Pancake-like clouds of #gases, dust and ice surrounding young #stars – known as #protoplanetary discs - are where the process of #planet formation begins. Through a process known as core accretion, #gravity causes particles in the disc to stick to each other, eventually forming larger solid bodies such as #asteroids or #planets

Alright #Astrodon I migrated here a couple of days ago and the time for introduction is nigh overdue.

I'm an astrophysicist, currently postdoc at #ZAH in #Heidelberg. I spend most of time thinking about planet formation and the evolution of gas and dust in #Protoplanetary discs. Particularly the ones that are a bit wonky, i.e, warped and misaligned. The wonky ones have a lot of interesting physics! We should all care about the wonky ones!

Hey #Astrodon I think it's time for an #introduction.
I'm an Associate Professor of #astrophysics at the Centre de Recherche Astrophysique de #Lyon, #France (affiliated with #UniversitéLyon1, #ENSdeLyon, #CNRS). I work on the first stages of #planet formation, more specifically the evolution of gas and dust in #protoplanetary #disks with numerical simulations. I also compute synthetic observations from them.

This has to be one of the coolest space objects I've seen in a while. While exploring around in #SpaceEngine, I came across this odd looking object. I though it was an artifact or glitch due to the procedural generation used by the software in some unmapped areas of the galaxy, but no, this exists! It's called the Red Rectangle #Nebula (HD 44179), a #protoplanetary nebula located in constellation Monoceros. It's around 710 ± 100 pc away. #Hubble actually imaged it:
