The Hidden Depths Of The Dark Cloud Hiding Newborn Stars

For Forbes:

The third dimension is one of the biggest obstacles in astronomy. We see the stars, but we don’t know how far away they are without some additional information, which requires scientific cleverness. And when the object we’re studying is a nebula — a cloud of gas or dust — we only see its profile, not its full three-dimensional shape. But a new paper shows that, in some cases, we might be able to deduce the full shape of a nebula by how it vibrates: a kind of magnetic nebulaquake.

Astrophysicists Aris Tritsis and Konstantinos Tassis compared a sophisticated computer simulation to observational data on an object called the “Musca molecular cloud”, also known as the “Dark Doodad”. (“Musca” is the name of the constellation where it’s found, which means “the fly”. It’s only visible in the Southern Hemisphere.) They found that even though the Doodad looks like a filament, it’s actually more like a pancake that we’re seeing edge-on. Beyond the curiosity aspect (who wouldn’t want to study the Dark Doodad?), this result is important for understanding how stars are born.
