Meet the AAS Keynote Speakers: Joel Kastner
Learn all about beautiful planetary nebulae with Joel Kastner at his plenary talk at #AAS242 this afternoon! We interviewed Kastner about his journey into astronomy here:
Dust n’ H2
The diffuse interstellar medium (ISM) isn’t as smooth as its name makes it sound. In today’s astrobite, we look at one mechanism for clumping up the diffuse ISM, and how that mechanism could affect molecular hydrogen formation.
How the other half spins: probing the huge gas cloud around the Milky Way
Our galaxy is not just made up of stars and dark matter, but a huge weight of dust, extending out much further than we can see. Now we’re starting to pin down the properties of our surrounding mysterious gas cloud, and new evidence shows that it’s busy doing it’s own thing.

Mealtime for Sgr A*
Remember that tidal disruption event we talked about earlier this year, where a star got just a little too close to a quiescent black hole? Well, here’s our chance to witness something similar, happening in the center of our very own galaxy!
