Posted on 05/26/2012 9:48:31 PM PDT by SunkenCiv
Explanation: Can you spot the planet? The diminutive disk of Mercury, the solar system's innermost planet, spent about five hours crossing in front of the enormous solar disk in 2003, as viewed from the general vicinity of planet Earth. The Sun was above the horizon during the entire transit for observers in Europe, Africa, Asia, or Australia, and the horizon was certainly no problem for the sun-staring SOHO spacecraft. Seen as a dark spot, Mercury progresses from left to right (top panel to bottom) in these four images from SOHO's extreme ultraviolet camera. The panels' false-colors correspond to different wavelengths in the extreme ultraviolet which highlight regions above the Sun's visible surface. This was the first of 14 transits of Mercury which will occur during the 21st century. Next week, however, an event much more rare but easier to spot will occur -- a transit of Venus across the Sun.

How can there be two different Astronomy picture’s of the same day?
*shrug* It’s a big universe...
Silly, because it’s a leap year! ;’)
There are many days.
For once, I had no trouble observing the planet described in the blurb. Tiny little thing compared to the sun, isn’t it.
However, Mu Cephei is 1650 times larger than the sun, so everything is relative.
If Mu Cephei were to switch places with the sun, all of our planets up to Jupiter would be inside it.
I thought I’d discovered another planet when I was looking at those photos, but it was just a piece of my pop tart.
