Astronomers Spot Two Dust Bunnies Hiding in the Early Universe

Christopher Intagliata: This is Scientific American’s 60-Second Science. I’m Christopher Intagliata. If you’ve ever looked up at the Milky Way, you’ve seen what’s known as cosmic dust. Pascal Oesch: When you see this band of the Milky Way, you can see these dark patches. So that’s really just dust that is obscuring the stars behind it. Intagliata: Pascal … Read more

Astronomers Spot a Ghostly ‘One-Winged Butterfly’ Blazing Through Space

The beautiful birth of a star has produced an exquisitely ethereal structure in interstellar space. It’s called the Chamaeleon Infrared Nebula, located about 520 light-years away, and in a new image from the NSF NOIRLab’s International Gemini Observatory in Chile, it appears in the sky like a pale gossamer butterfly wing.   At its core, … Read more
