I'm not sure how to ask this so it makes sense.

What kind of exciting new data are they hoping for from the Venus transit? What kind of measurements and calculations and stuff are they going to be able to take, that they never were able to before? What kind of "We used to think...but now we know..." space information are they going to be looking for?

During the last one in 1882, they were able to take some measurements that confirmed some of the distances in the solar system, yes? And the one in 1769, too.

So what kind of thing are they going to be looking for, this time around? I found this (http://www.vt-2004.org/Background/Infol1/BIS-A1.html), but it's mostly about distances and measurements. Are they expecting to find out anything new from this one?

The only one I remember hearing about is helping figure out how to detect extrasolar planets (http://www.vt-2004.org/Background/Infol1/BIS-E1.html).

The current SOHO hot shot (as of 25 May) (http://sohowww.nascom.nasa.gov/) discusses the science a bit. From SOHO's point of view, Venus will pass "below" the sun and occult part of the corona. They will be able to use this to help improve the measurements of coronal temperature. Venus will enter the LASCO C3 field of view on 3 June, so stand by. :)

Okay, thanks, that's what I was getting at.

Scientists To View Venus' Atmosphere During Transit, Search For Water Vapor On Distant Planet (http://www.sciencedaily.com/releases/2004/06/040604025320.htm)


On June 8, peering through a specialized solar telescope in the Canary Islands, Brown will study the chemical composition and winds of Venus' upper atmosphere, a region poorly observed until now.
