Thanks to a tweet by Ars Technica's John Timmer, I was introduced this morning to Gomez's Hamburger—a delightfully named astronomical feature about 900 lightyears away from Earth.
The name is funny. But what makes Gomez's Hamburger worth posting about here is that it gives you a glimpse of a process you've probably only read about before. Scientists think that planets form out of clouds of gas and dust circling a star. Over time, bits of dust clump together into larger objects, which in turn collide and smush into even larger objects. Eventually, instead of a star sitting in a dust cloud like Pigpen from Peanuts, you've got a classy, mature star orbited by a series of planets.
Gomez's Hamburger is most likely a young star sitting in a dust cloud. The dust is actually the meat in this sandwich. The "buns" are actually light reflecting off of the dust.
Confused about what we do and don't know about the relationship between humans and Neanderthals? This video by Lynn Fellman will get you up-to-date on the basics—including some of the questions that haven't been answered yet. It doesn't cover everything, but it is a nice primer on recent research and how that research was done.
EDIT: Bad news: Autoplay continues to be the devil. The good news: If you go to Lynn Fellman's website to view the video there, it doesn't autoplay. So follow the link and enjoy.
