I'd love to see it, but "show me the money" and don't believe it until they "bend tin" given past disappointments.

To Far Centaurus

Today's Astronomy Picture of the Day shows "active galaxy". The visible image is only a portion of what is going on there.

Swirling Complexity

Today's Astronomy Picture of the Day shows the complexity found in the Great Nebula of Orion. This one is worth making into your desktop image!
