We report on Day 4 of the winter AAS meeting in Seattle, WA. Highlights include an exploding space cow, a discussion of data in astronomy, the latest look at the possibility of life beyond earth, and an exploration of climate impact much closer to home.
We can learn a lot about the history of the universe from the stars we see in the night sky today. In today’s astrobite, we look at the history that certain carbon-enhanced, metal-poor stars might be trying to tell.
There ain’t no gosh darn part (of this Astrobite about star formation in dwarf galaxies) you can’t tweet.
A supernova that Tycho Brahe studied in 1572 may yet have something to tell us about what causes supernovae.
A mysterious pair of stars speeding through the outskirts of our galaxy together puzzles astronomers
Today’s paper describes models of what a nearby supernova would do to a young planetary system, and looks at whether the same may have happened to our own solar system.
