Click on the image above. My Vote for best homepage, other than An Unreliable Fingerpost, is the Astronomy Picture of the Day. Each day of the week, including weekends, they add a new picture of astronomical or atmospherical interest. The pictures also come with a short explanation of what is being shown.
Images of deep space are some of my favorites. If you take a close look you can see tiny galaxies in the background, millions or billions of light years away. It is fascinating to contemplate what might exist in those galaxies.
Shown here is a non-descript galaxy known only as NGC 4921 (approx. 320 million light years away). What might be happening in any of the hundreds of millions of solar systems within it?
Click on the image above and gaze at the countless tiny galaxies, even further away, in the background.
If you were holding a grain of rice at arms length while looking at the night sky, this image would represent a portion of the sky much, much, smaller.
