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.
If there’s one thing that 21st-century telescopes have shown us about Pluto, it’s that there’s still a lot we don’t know about our very far-off neighbor. Today we look into just one of Pluto’s many mysteries: the formation of its complex five-moon system.
There’s more happening for the surface of Mars than just piles of Martian rock. In today’s astrobite, we look at laboratory experiments done right here on Earth to learn more about the climate of our dusty neighbor.
