AAS #237: five things we learned Here are the key take-outs from the 237th meeting of the American Astronomical Society. The Hubble Space Telescope captured this image of the "butterfly wing"- shaped nebula, NGC 2346. The nebula is about 2,000 light-years away from Earth in the direction of the constellation Monoceros.

Last year it was in Honolulu. But this year, thanks to COVID-19, it was online—something that AAS had already practised for smaller meetings as far back as June 2020. Not surprisingly, given the rehearsal, they did a smash-bang job of it. But they also had a remarkable amount to present… plus a lot of fun.
