I just happened to look out the window last night (Sunday, July 15, 2018) at the right time and saw the Moon and Venus hanging out together.
“About 1.1 billion years ago, two black holes coalesced. They had danced around each other for billions of years, losing energy and swinging closer, until they could no longer resist each other's embrace. Spiraling in, they merged, and released a quaking shout of gravitational waves that echoed across the cosmos.”
Phil Plait on syfy.com has a nice story about a black-hole merger.
This is cool, though I don’t know why people are always picking on Pluto. (It may also need an asterisk stating that Saturn needs to be at an angle like that.)
The Washington Post has a good article, “What the new gravitational waves discovery means for the future of astronomy.”
“Ironically, the bounty was made possible when the Kepler space telescope's pointing system broke.”
