According to one theory of planet formation, the secret to forming massive planets is through itsy-bitsy, teeny-weeny pebbles of dust. In today’s astrobite, we explore what sort of planets these little pebbles could form.
With the awesome power of ALMA, scientists have observed a variety of dust gaps in protoplanetary disks. In today’s astrobite, we explore how these gaps might be related to planet formation.
The redshifts of active galactic nuclei (AGNs) can help us piece together the universe’s evolutionary timeline. Unfortunately, measuring these redshifts can be pretty tricky. In today’s astrobite, we look at a trick for estimating and constraining the redshifts of AGNs that are – ironically enough – partially obscured from our view.
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.
The Rosetta orbiter sent back lots of mystifying data from its time spent following the comet 67P/C-G. Today we focus on just one of its discoveries: molecular oxygen in the comet’s coma.
