Above, a kilometer high cliff on Comet Churyumov-Gerasimenko. The largest boulders at the cliff bottom are about 20 meters wide. The photo was taken a few weeks ago by the Rosetta orbiter.
Here's an interesting photo (above). It's a composite picture of our galaxy's core taken by Hubble and the Spitzer X-ray telescope. The white splotch on the lower right is a star cluster surrounding Sagittarius A, the super massive black hole at the galactic center.
In case the wide photo showing the Sagittarius A cluster is obscured by my sidebar , here's (above) an unencumbered enlargement. There's a nearby cluster on the upper left, which is puzzling. How did it escape being ripped apart by Sag. A? And what are those rake marks on the upper right?
Finally, here's (above) a new and improved picture of the M16 star nursery taken by Hubble. You probably saw the earlier version of this that was taken 20 years ago and is considered by many to have been Hubble's greatest achievement. This latest photo benefits from a wider field and a higher res.
