The world's first image of a black hole was made public on April 10, 2019.

"In science-speak, the shadow cast by the M87 black hole is around 40 microarcseconds wide when viewed from the Earth. An arcsecond is 1/3600th of a degree. And there are 1 million microarcseconds in an arcsecond. Again: The shadow cast by the black hole is tiny. Compared to the full moon, the shadow cast by the M87 black hole is 46.5 million times smaller. Taking a picture of the shadow cast by a supermassive black hole is like taking a photo of a quarter in Los Angeles all the way from Washington, DC."

Is there sufficient interest to have a nighttime star viewing party on May 1st? (Or maybe May 8th?) We'd meet on the UT campus around 8:30 pm. I'd recommend bringing a parent.

Proxima Centauri is 4 light years away. Ambitious space mission Breakthrough Starshot is developing a way to push spacecraft there at a fifth of the speed of light.
