This is an interesting thing to look forward to. In about 6 billion years, the Milky Way will likely collide with the nearby Andromeda Galaxy. Hmm, I wonder what I'll be doing?

Valla, I don't remember how I came across the site, but it has years of daily photos of and about space. I have spent hours there and I don't think I'll ever catch up to the present photos. Some are simple, some are absolutely awesome.

There are some amazing pictures on that site Mousetrails, thanks. I've always been fascinated with astronomy and could gaze at the pictures for hours. I loved "Earth at Night" but don't quite understand how it could be night over the entire earth at the same time. The picture must have used two photos fused together, which were taken at different times.

First gravitational waves form after 10 million years

If two galaxies collide, the merging of their central black holes triggers gravitational waves, which ripple throughout space. An international research team has now calculated that this occurs around 10 million years after the two galaxies merge -- much faster than previously assumed. Ref. Source 8m.
