I wonder if SIRTF ( sorry Spitzer Space Telescope (http://www.universetoday.com/forum/index.php?showtopic=1477) :D ) will produce somthing like this ? :unsure:


do you think the comet looking thing heading towards the center of the galaxy in this picture is the southern crown (http://antwrp.gsfc.nasa.gov/apod/ap021002.html) (picture from APOD)?

Spitzer Space Telescope otherwise and formerly known as SIRTF has produced the first batch of images now avaible for PUBLIC viewing and appreciation. Check out the Press Release and images at links provided for below.

Well this looks a bit like your original picture:


And this one ain't bad:


Both from SIRTF.

As a master of understatement I'd like to say ... Those pictures are rather good, aren't they?

I downloaded a few of the SIRTF images in full size TIFF, it took a while on my dialup connection, but it was worth it. So crisp! But it would be good if more images were released, at the moment there aren't all that many pictures. The Hubble has got a much bigger range of crisp images.

Those first images are indeed BREATHTAKING! Spitzer is zillion of light years (L.Y.) better than IRAS! The infrared sky sure compares well with its optical counterpart doesn't it? ;) Do check out the Formalhaut disk pics. They are simply AWESOME!

The images just released are classed as Early Release images taken just so that they could be released within three months of launch. Usually there is an embargo of about a year between when an image is taken with a space telescope eg Hubble to when it is released. This is so that the astronomers that spent their time and energy putting together the proposal for the image to be taken in the first place get to be the ones who make the discoveries.

These images were probably part of what is called Director's Time. The Director of the telescope gets maybe five days a year when he can point the telescope at anything he likes. This is how things like the Hubble Deep Field got taken. It's a reward for being the guy who makes all the important decisions.

You also have to remember that Hubble has been in orbit for over 10 years and so has had more time to build up a huge and impressive archive of images. The SST will hopefully do the same over its operational time though it is limited by the time it takes for the helium to evaporate. After this is gone it won't be able to take such good images, though it may be still able to some science.
