If you know of a particularly good site on a subject that we haven't listed , or you have or know of a personal site that may not be listed on a search engine, feel free to bring it to our attention so we can add it, if appropriate.

We would appreciate any feedback, good or bad, so we can update this list and try to make it more user friendly.

Hopefully this will be something we can all benefit from :)

:unsure: A couple of online newsletters that may be of interest;

The Magellanic Clouds Newsletter (http://www.astro.uiuc.edu/projects/mcnews/MCNews.php)

The Galactic Center Newsletter (http://www.aoc.nrao.edu/~gcnews/index.shtml)

Planetary News

SpaceRef (http://www.spaceref.com/) has planet specific news sites for the Moon today (http://www.moontoday.net/), Mars today (http://www.marstoday.com/), Mercury today (http://www.mercurytoday.com/), Juipiter today (http://www.jupitertoday.com/) and Saturn today (http://www.saturntoday.com/). I think Juipiter today was set up mainly for Galileo, and the others as missions began.

Worth spliting up and linking seperately under each planet?

Astro-Photography sites:

Astrophotography By Jon Kolb (http://www.home.datawest.net/jkolb/)

An Atlas of the Universe (http://www.anzwers.org/free/universe/index.html) has some great links Star Cluster and Nebula within 10000 ly (http://www.anzwers.org/free/universe/nebclust.html) shows the distances for such objects, as the Cats Paw (NGC 6334)

All the sky (http://www.allthesky.com/nebulae/pipe.html) has some great links to catalogs like, E. E. Barnard's Catalog of Dark Nebulae (http://www.dvaa.org/AData/Barnard.html)

Naoyuki Kurita, stellar scenes (http://www.ne.jp/asahi/stellar/scenes/object_e/pipe2.htm)


Axel Mellinger (http://canopus.physik.uni-potsdam.de/~axm/images.html) in particular his all sky panarama.

Star Echoes (http://www.astrosurf.com/lorenzi/index.htm), I like this site, in particular for the wide shots of Orion (http://www.astrosurf.com/lorenzi/images/nslf.htm)


I think you may want to add this as a seperate section.

First The catalog of catalogs (http://cdsweb.u-strasbg.fr/cats/U.htx) from the CDS, contains brief descriptions, but is one of the most thorough.

INSPEC (http://www.iee.org/publish/support/inspec/document/astron/) has a lot of technical resources, in particular, a list of astronomical designations. No links to catalogs or databases. I think Simbad (http://cdsweb.u-strasbg.fr/Simbad.html) stands alone, as far as atlases go.

A Timeline of DSO catalogs (http://home.ix.netcom.com/~bwilson2/barbarasweb/History.htm) by Barbara Wilson

The Northern Caldwell Objects (http://www.3towers.com/Caldwell_objects.htm)

NRAO Catalogue of SNR (http://www.mrao.cam.ac.uk/surveys/snrs/index.html) (super-nova remnants)

LSPM North catalog (http://www.arxiv.org/PS_cache/astro-ph/pdf/0412/0412070.pdf) is a comprehensive list of 61,977 stars north of the J2000 celestial equator that have proper motions larger than 0.15 seconds of arc per year (local-background-stars frame). (spotted by Antoniseb (http://www.universetoday.com/forum/index.php?showtopic=5589&st=0&#entry52643))

Astronomy clubs

Astronomy Clubs world wide (http://www.astronomyclubs.com/)

Tri-city astronomy club of Southeast Washington (http://www.tri-cityastronomyclub.org), amongst the offerings on their site is a biography of Charles Messier with guides to THE MESSIER MARATHON (http://www.tri-cityastronomyclub.org/CharliesMBio.htm) and detailed finder charts for CALDWELL objects (http://www.tri-cityastronomyclub.org/Caldwells.htm)

Ames Area Amateur Astronomers (http://www.amesastronomers.org/)

And I have to recomend Hawaiian Astronomical Society (http://www.hawastsoc.org/deepsky/constellations.html) for their Deepsky Atlas.

For treatment of the different catalogs of stars, most seem to be connected to Astronomy software sites, The Guide is a software package, this page (http://www.projectpluto.com/catalogs.htm) outlines the catalogs it uses, for example. Desktop universe is another

The Schmidt Cassegrain website (http://www.sctscopes.net/) by Ted Kurkowski, has one of the best lists of DSO (deep sky Objects) (http://www.sctscopes.net/Glossaries/DSO_Database_Notations.html)l catalogs I have found. From Abell to Westr.

SEDS Goes further including longer discriptions (http://www.seds.org/messier/xtra/supp/cats.html)

This is HST (http://www.stsci.edu/hst/proposing/docs/target-naming) Target naming conventions, this includes a link to proposals (in case any of you UT Rouges want to have a go ! Best get in quick before she crash and burns I guess!)

Not completely off the topic, but perhaps a History section ??

Sharpless catalog of HII regions. While looking for some close ups of Sh2-3, I came across This site (http://www.angelfire.com/id/jsredshift/sharp.htm), it has a little bit of history about Sharpless and Lynds. Lynds seems to have moved from studying HII regions in our galaxy to other galaxies, An atlas of dust and HII regions in Galaxies (http://nedwww.ipac.caltech.edu/level5/Lynds/frames.html), This article (http://www.1000plus.com/StalkFire.htm) mentions her bright and dark nebula Atlases. Stewart Sharpless is mentioned in This site (http://www.nofs.navy.mil/about_NOFS/hist.html) about the history of the USNO Flagstaff station, and he is mentioned in this site (http://starryskies.com/articles/pr/LifeandTimesOldestPlanet.html) and this site (http://www.phys-astro.sonoma.edu/BruceMedalists/Osterbrock/index.html) as one of the first astronomers to realise our position within a spiral galaxy.

Unfortunately, I still have not found anything of Sh2-16, It looks like a three stars with some nebulosity, any help appreciated!!! :D
I found it extremely helpful in locating the galactic center in the visual wavelength, it appears in This image (http://www.astro.ucla.edu/~jlu/gc/journey/) just below the cross marking the center of our galaxy.

For Biographies

HAO (http://www.hao.ucar.edu/public/education/education.html#history) has some great Bios from Aristotle (http://www.hao.ucar.edu/public/education/sp/images/aristotle.html) to Bernard Lyot (http://www.hao.ucar.edu/public/education/sp/images/lyot.html)

And we would have to include The Galileo Project (http://galileo.rice.edu)


Edward Emerson Barnard (http://astro.uchicago.edu/yerkes/virtualmuseum/Barnard.html)

Edward Emerson Barnard (http://www.belmontnc.4dw.net/dkneb.htm)at the Belmont society.

Hope I haven't spwralled this post

You simply must try these sites!

First, there is a nice site at NASA, Near Earth Object Program (http://neo.jpl.nasa.gov/) that has a Java simulation of Near Earth Objects, a highlighted list of Close Approaches(updated daily), and a list of the Orbital Elements for nearly 3000 asteroids. Also, there is a list for Comets.

Then, and this is really the neat one, there is a FREE PROGRAM called CELESTIA (http://shatters.net/celestia/).

Celestia is a real-time 3D space simulation featuring a database of over 100000 stars, nearly a hundred solar system objects, and a complete catalog of neat stuff, like fictional space ships and space stations from 2001: A space Odyssey, Star Trek, Star Wars, Babylon 5, Stargate and others.

It's like a joyride through a planetarium! And here's the neat part. You can copy the orbital elements from the Nasa-NEO site into a template(simple text-file) for Celestia, drop it into the resources folder(after you have downloaded Celestia to your computer...for free) and it will appear in the simulation, in the right place. You can go forward and backward in time, and move seamlessly to anywhere, even other galaxies, at light speeds plus.

I forgot to eat for nearly a day after I downloaded it. :blink:

Download size for Mac and PC versions is about 12+ megabytes, expands to about 18 mb's. They also have a page called The Celestia Motherload (http://celestiamotherlode.net/)
which contains links to about 3 gigabytes of additional files for most of the locations and objects in the Universe that you could possibly think to visit.

2004-Aug-24, 05:54 AM
Sh2-13 (http://www.astroimages.com/m6.htm), wow doesn't it help when you add words like nebula to your search!

Astronomical Images by George Greaney (http://www.astroimages.com/index.html) more astrophotography!

Another site I have to mention is A CCD Tour of the Universe by Jan Wisniewski (http://www.astrosurf.com/jwisn/index.html), in particular for it's lovely illistrations of the constellations

The Saguaro Astronomy Club (SAC) (http://www.saguaroastro.org) has a variety of downloads (http://www.saguaroastro.org/content/downloads.htm)

Aladin has some black and white images of Gum70 and in colour (http://aladin.u-strasbg.fr/AladinPreview?GUM%2070)
Put in GUM 70 , including some object databases

at the Aladin sky atlas (http://aladin.u-strasbg.fr/AladinPreview). get an RGB image, there is a very subtle colum near the star HD 161408.

2004-Aug-24, 07:16 PM
Hey, guys, I was looking around and I found a few that might have been visited before but that I think should definitely be noted within this string:

[non-mainstream link removed]

[linkfarm reference removed]

Through no fault of my own, I found this FAQ site. Read on!

Lastly, I found this site at random:
I'm not sure what good it'll do for anybody who reads it, but for Cosmology-minded minds like me, it works fine as a guidesite.

Sharpless Catalog of HII regions (http://adsabs.harvard.edu/cgi-bin/nph-bib_query?1959ApJS....4..257S)

2004-Sep-20, 05:35 AM
Another Catalog

Hickson Compact Groups (http://www.astro.ubc.ca/people/hickson/hcg/data.html), this catalog has 100 listings.

Arp (http://nedwww.ipac.caltech.edu/level5/Arp/frames.html)

Another list of catalogs (http://www.astrosurf.com/skylink/deepsky/database/catalog.html)

If catalogs are to be added, stars, nebula and galaxies would make good sub categories.

Nineplanets (http://nineplanets.org) list of large telescopes (http://nineplanets.org/bigeyes.html), also has a great biography of Ptolemy (http://nineplanets.org/psc/theman.html).

2004-Oct-09, 03:47 AM

This is an online list of all know Herbig Haro objects.

APOD images and descriptions of Herbig Haro objects (http://antwrp.gsfc.nasa.gov/cgi-bin/apod/apod_search?Herbig+Haro)

My interest in HH objects was rekindled when I found Hubbles Variable Nebula (http://antwrp.gsfc.nasa.gov/apod/ap991020.html), and a claim that it is a HH object, associated with a T Tauri Star. I wonder if this is common?

The closest I have come to finding a catalog of T Tauri stars is
http://legacy.gsfc.nasa.gov/W3Browse/all/v.../vstarsusp.html (http://legacy.gsfc.nasa.gov/W3Browse/all/vstarsusp.html)
The VSTARSUSP database containing the New Catalog of Suspected Variable Stars (NSV).

One of the better lists I have seen for star types. I am not sure how to access it, nor is anyone is interested, I will post when I figure it our though :)

heres one in Moscow,

APOD images and descriptions of T Tauri Stars (http://antwrp.gsfc.nasa.gov/cgi-bin/apod/apod_search?T+Tauri+stars)

ATNF Pulsar Catalogue, v1.2: Documentation (http://www.atnf.csiro.au/research/pulsar/psrcat/psrcat_help.html)
This looks like a comprehensive treatment of Pulsars, I Have seen a shortlist of about a hundred but this news release (http://www.csiro.au/news/mediarel/mr1998/mr98259.html) from Parkes put the number at over a thousand from Parkes alone in 1998.

the search for a thorough list of Pulsars continues.

Basic (http://astrosun2.astro.cornell.edu/academics/courses//astro201/pulsar.htm)

NASA (http://science.nasa.gov/newhome/help/tutorials/pulsar.htm), that explains that Pulsars emit along most wavelengths

A Gravitationally Powered Oscillatory Pulsar Model (http://www.s-4.com/pulsar/)

ATNFPULSAR (http://heasarc.gsfc.nasa.gov/W3Browse/all/atnfpulsar.html), has a great introductory and advanced introduction to pulsars, along with a catalog, (J0815+09 doesn't seem to be on it though)

The Princeton Group (http://pulsar.princeton.edu/) seem to be the other main group and have som great links including these Pulsar Maps (http://pulsar.princeton.edu/pulsar/map/PulsarMap.html)(JAVA), again, doesn't have J0815+09

Some info on Nomenclature;

Basic (http://www.spektros.de/nomencl.html)

and from "Ecology" of Magnetic Rotators (http://xray.sai.msu.ru/~mystery/articles/review/node22.html), well somthing else.

I am now looking at catalogs of molecular clouds. This was inspired by the Diagram (http://www.solstation.com/x-objects/1806-20.htm) of objects in between us and LBV 1806 - 20.

There are two obvious classifiers W and MC. So far, the best I have managed is an article about W31 (http://adsabs.harvard.edu//full/seri/ApJ../0347//0000338.000.html), the largest HII region in the Milky Way.

I have been looking at a lot of online Star Atlases, historical and current, and was thinking of a UT Star Atlas.
This could be done in a number of ways. For starters, I will list the best I have found so far online, then
we could sample pictures with links to objects in an Atlas thread, or Fraser could open a seperate section
with a thread for each section, maybe in astrophotography, and people could post their astrophotographs
by constellation, just an idea, what do you think :) .

Anyway, here are my favorite

Tim Thompson
2005-Jan-25, 11:46 PM
First, I would like to endorse, for what is's worth, a few sites already mentioned by others.

Devilmech already pointed out Ned Wright's Cosmology Tutorial (http://www.astro.ucla.edu/~wright/cosmolog.htm), and I want to emphasize that pick. It's more than the title implies. The News of the Universe (http://www.astro.ucla.edu/~wright/cosmolog.htm#News) section keeps you up to date on current events & research in cosmology. The Cosmological Fads & Fallacies (http://www.astro.ucla.edu/~wright/errors.html) section points out flaws in some of the more popular, but unsound alternative cosmologies. The main tutorial section has been translated into Italian (http://www.vialattea.net/cosmo/) and French (http://www-cosmosaf.iap.fr/Wright.htm).

Starlab points out two valuable sites. The Usenet Physics FAQ (http://math.ucr.edu/home/baez/physics/) has combined the old, separate FAQs on physics and relativity & cosmology into one highly useful reference, along with a list of similar FAQ files elsewhere. The Level5 Knowledgebase (http://nedwww.ipac.caltech.edu/level5/) from Caltech is a huge database on astronomy, astrophysics and cosmology; it includes a long list of papers (http://nedwww.ipac.caltech.edu/level5/araa.html) reproduced from the Annual Reviews series, selected chapters (http://nedwww.ipac.caltech.edu/level5/cup_monographs.html) from Cambridge University monographs, and a wealth of other information.

The Level5 site is part of the extensive NASA/IPAC Extragalactic Database (http://nedwww.ipac.caltech.edu/), Amongst other things, you can look up data & images of just about any extragalactic NGC object. The HyperLeda Database (http://leda.univ-lyon1.fr/) provides a similar service, you can look up data on galaxies galore.

Now I haven't noticed the rest of these listed yet, but I find them useful, and you might also.

The ArXiv.Org e-Print archive (http://cul.arxiv.org/), hosted by the library at Cornell University, is a repository of pre-prints & re-prints of scientific papers. In some cases, the papers can go back as far as about 20 years. Originally devoted to physics & mathematics, the archive now includes non-linear sciences (i.e., chaos theory), computer science and quantitative biology. In all cases the whole paper is available, usually as a PDF or PostScript file.

The NASA Astrophysics Data System (http://adswww.harvard.edu/) is a similar archive of published papers, though in this case the whole paper is often not available (especially the recent ones which are still under close supervision by the original copyright holders), and sometimes even the abstract is not, just the reference. Over 1,000,000 papers in astronomy & astrophysics, and nearly 2,000,000 in physics & geophysics, sometimes dating back centuries. It also interfaces to the ArXiv archive.

Living Reviews (http://www.livingreviews.org/) is an online, free-access technical journal. It started out devoted entirely to relativity, but has now branched out to include solar physics. The papers are called "living" reviews, because once published on the web (and available as PDF too), the papers are periodically updated by the authors, in a manner not really plausible in the more traditional formats. Not for the mathematically faint-hearted, but a reliable source.

I have also written a few of my own webpages (http://www.tim-thompson.com/faqs.html), which might be interesting. Most relavent to this forum perhaps, would be Solar Fusion & Neutrinos (http://www.tim-thompson.com/fusion.html), The Hertzsprung Russell Diagram And Stellar Evolution (http://www.tim-thompson.com/hr.html), and the cosmic microwave background (http://www.tim-thompson.com/cmb.html).

Finally, I will recommend the Physical Reference Data (http://physics.nist.gov/cuu/index.html) site from the National Institute of Standards & Technology. The reference site will show you the currently accepted values for all of the fundamental & derived constants of physics, such as Planck's constant (http://physics.nist.gov/cgi-bin/cuu/Value?h|search_for=universal_in)!, or the Newtonian constant of gravitation (http://physics.nist.gov/cgi-bin/cuu/Value?bg|search_for=universal_in)!.

Hello Everyone,

I would like to add my two sites for consideration.

http://www.marsartgallery.com features images derived from the various missions to Mars. It just went live a couple weeks ago and I still have much content to add.


htp://www.astrodigital.org my other site with sections on Mars, Space Exploration, etc. Note that some parts of the site are quite dated.

BTW: if you are in the Chicago area you may want to visit another of my other web sites:

http://www.chicagospace.org the home of the Chicago Society for Space Studies.

2005-Mar-23, 03:25 AM
One I am surprised not to have seen mentioned before on the space exploration side is the

Encyclopedia Astronautica (http://www.astronautix.com/)

by Mark Wade containing an enormous amount of information on all space technology, past and present. Well worth a look.

Really good idea, this. I have been looking at the photographs people have put on UT and it has been wonderful, so the idea of a site with a growing atlas of maps and photographs with everyone able to contribute and view - simply fantastic! This sort of thing makes internet truly meaningful.

And thank you, everyone, for the sites today.

I did a quick scan, and I don't think these sites are listed yet. One is pretty obvious, the others are physics related. Those of you who know me from the BABB will remember that these are among my favorite references.

Biography and research

The Nobel Prize site (http://nobelprize.org/).
This has the biographies of all of the Nobel winners in all fields. It also has their Nobel lectures, some of which can be fairly detailed descriptions of the work that won them the prize.

Science News

American Institute of Physics Physics News Update (http://www.aip.org/pnu/)
My favorite link for breaking news in physics and some astronomy. Much more detailed and less sensationalistic than the typical press releases.

Physical Review Focus (http://focus.aps.org/)
From the American Physical Society. Similar to PNU, but with specific links to articles published in the Society's journals Physical Review and Physical Review Letters. Notes on cutting edge research.

Physical Review Letters (http://prl.aps.org/)
Speaking of cutting edge research, PRL is probably one of the most prestegious journals in the field. You'll need a subscription or pay to read the actual articles, but you can browse the abstracts for free. Any university physics library will have a subscription if you have access to one. Be warned, however, this journal is aimed at the practicing physicist. The amateur may have some difficulty, but don't let that deter you from browsing.

General Resource

The Particle Data Group (http://pdg.lbl.gov/)
Ahhhh, Saving the best for last. As a particle physicist, it's my favorite reference site. This is the encyclopedia of all data on particle physics. It also has review articles on tests of General Relativity, Big Bang cosmology, Big Bang nucleosynthesis, the CMB, Dark matter, and other astronomy-related topics. This site should be required reading for any ATM (against the mainstream) type. Know the status of current science before casting stones. It's also useful for others interested in cosmology and how particle physics relates to it. Again, it's aimed at the practicing scientist, but knowledgeable amateurs should be able to get a lot out of it.

2005-Sep-08, 03:52 AM
The Particle Data Group (http://pdg.lbl.gov/)

I can vouch for the last. Outstanding site.

More HLLV news:




More here:
http://www.safesimplesoon.com (Updated)

The Euros will be building this:

The Ariane M the European Very Heavy launch vehicle:

The Russians are also looking at HLLV

Aldridge report out:
See Page 29-33 of 64 In Adobe
Page 27-30 hardcopy



But Mike Griffin's hands have been tied, and EELV pushers have been trying to use their influence upon the White House OSTP--even though EELVs are an inferior product:
http://www.spacedaily.com/news/oped-5za.html http://www.thespacereview.com/article/150/1


"The Aldridge Commission suggested that a heavy-lift vehicle was necessary, calling it an “enabling technology” for implementing the vision, yet also suggested that heavy-lift vehicles might be developed commercially..."


Michael Griffin, NASA’s associate administrator for exploration from 1991-1993, says the most logical approach, all things considered, is to spend the $3 billion or $4 billion it would cost to build a shuttle-derived heavy lifter and forget about EELV-driven approaches.


"This examination shows there is no significant cost savings by pursuing the use of numbers of medium-lift vehicles when compared to the development of a new, shuttle-derived heavy lift booster. The development of such a heavy-lift booster supports the President’s space vision by providing the capability of lofting heavy payloads to the Moon in support of the construction of a lunar base as well as providing the capability to conduct other missions. I believe the development of a heavy booster in conjunction with the appropriate use of medium-lift boosters and modular spacecraft represents the most effective strategy for the US manned space program."


The Air Force has been an enemy of the Space Program.

It's great to see this still being used. I haven't had a chance to update it, seeing as I've been deployed to Iraq for most of a year, and various other real life issues took precedence over my love of astronomy and science.

That being said, I would like to update this thread to contain current and useful info, so I shall need some input from any of you that might use it. I need you to tell me what info you wanna see here, and how I should present it. I'm afraid the current layout is a bit confusing, so I'd like to perhaps combine a few sections and make it more "user-friendly". Any input or ideas in this regard, please post them, and I promise I shall get around to updating this thread post haste.

I definitely appreciate the lists posted recently on the forum on web resources.

For newbies just getting back into astronomy/related sciences and browsing online, does anyone have any suggestions on criteria these web resources should meet? How could someone know what is reliable from what is edited/spinned?

I received this from the moderator of this forum, not a site, but both PDF-files are very to the point, with explanations accompanied by formulas to prove things and let you find out yourselves.

Quote :
"However, this paper, by Davis and Lineweaver, provides a good, succinct account of some popular misconceptions of modern cosmology.

Davis and Lineweaver have also written a less technical account. It was published in the magazine Scientific American, in March 2005. However, you can get a (PDF) copy from Charles Lineweaver's webpage - click on the link to it (it's at the bottom of the webpage).

If you don't understand anything in either, please just ask.

I think that you should first understand the basics of the "Big Bang" theory, before trying to understand how Dark Energy fits into the concordance model

Spaceman Spiff recently posted an article (http://www.bautforum.com/showpost.php?p=930970&postcount=1) describing Caltech cosmologist Sean Carroll's Preposterous Universe (http://preposterousuniverse.com/) site and its Cosmology Primer (http://preposterousuniverse.com/writings/cosmologyprimer/index.html) and FAQ (http://preposterousuniverse.com/writings/cosmologyprimer/faq.html) pages.

Current FAQ questions:

What is the universe expanding into?
Are distant galaxies moving faster than the speed of light? Wouldn't that violate relativity?
Does the universe have a center?
Could we detect the expansion of the universe by trying to measure the expansion of the solar system?
Is the universe finite or infinite? Will it recollapse or expand forever?
Is space flat or curved? I've heard both.
Is energy conserved in an expanding universe?
What is the difference between dark matter and dark energy?
Will we ever be able to detect dark matter or dark energy directly?
Isn't "dark energy" just like the older concept of the "ether"?
How do you know that dark matter isn't just ordinary matter that we can't see?
Could the inferred existence of dark matter and dark energy be due to a modified behavior of gravity?
Is inflation testable?
What came before the Big Bang?
Is our universe the only one, or are there others?


Just thought I'd add a link here to the Lineweaver "misconceptions" article mentioned above:
Scientific American: Misconceptions about the Big Bang (http://www.sciam.com/article.cfm?id=misconceptions-about-the-2005-03&print=true)

Baffled by the expansion of the universe? You're not alone. Even astronomers frequently get it wrong

We would appreciate any feedback, good or bad, so we can update this list and try to make it more user friendly.

Hopefully this will be something we can all benefit from http://top5choices.com/-pics-/eebie.jpg:)

www.liftport.com has a rather good FAQ and a very extensive archive of forum about the space elevator and related topics. Some of the details are likely wrong, but that likely is true of all sources of information.
www.spacesolarpower.wordpress.com has a mostly correct forum about solar power satellites and related topics. Neil

Is there a post like this for podcasts? Just a thought, as my Ipod is brimming with loads of completely free content, both audio and video, related to space, astronomy and the sciences.

From topic Links to all space exploration missions (http://www.bautforum.com/space-exploration/95993-links-all-space-exploration-missions.html):

Armchair Astronautics: Space Mission Links (http://armchairastronautics.blogspot.com/2009/11/space-mission-links.html)

Because I'll probably never be able to find it in that topic when I need it. But I can find it here.

Good advice from a Nobel Laureate.

Not sure if this has been mentioned:

Wayne Hu's excellent website on the Cosmic Microwave Background (http://background.uchicago.edu/~whu/)

Fraser Cain, owner (with Phil Plait, the Bad Astronomer) of this website, also owns Universe Today (http://www.universetoday.com/). This site has an excellent Guide to Space (http://www.universetoday.com/guide-to-space/) section; however, it's best to use this by entering a key word (or phrase) into the search box, making sure "Universe Today Search" is selected.

The videos of Richard Feynman's lectures on quantum electrodynamics (http://www.vega.org.uk/video/subseries/8) have been referenced a few times recently. These are pretty non-technical and a good introduction to how quantum theory explains the behavior of light.

Well, if I might "plug" my own website here, I have 2 magnitude calculators:
http://www.1728.org/magntudj.htm (this is a more advanced magnitude calculator)

and two calculators for Kepler's Third Law:
http://www.1728.org/kepler3a.htm (the more advanced calculator)

I've listened to a great set of lectures from Ohio State University available as a podcast or mp3:

Astronomy 141 - Life in the Universe (http://www.astronomy.ohio-state.edu/~pogge/Ast141/Audio/)
Astronomy 161 - An Introduction to Solar System Astronomy (http://www.astronomy.ohio-state.edu/~pogge/Ast161/Audio/)
Astronomy 162 - Introduction to Stars, Galaxies, & the Universe (http://www.astronomy.ohio-state.edu/~pogge/Ast162/Audio/)

I also live the Slacker Astronomy Podcast (http://www.slackerastronomy.org/)! Awesome!

This looong list will have me busy for a while!
