Did early Earth order delivery, or did it make its oceans at home?
Could interactions between a magma ocean and early hydrogen rich atmosphere have created liquid water on Earth?

Direct imaging exoplanets is difficult, but a new method of vetting targets has just helped three independent teams discover, and image, a new gas giant.
Most astronomy is done by graduate students, but many aren’t compensated fairly or treated well. Ongoing struggles to unionize, especially in the past year, might give the confused and frustrated graduate student hope headed into 2023.
Astronomers study the orbits of a sextuplet system, an absurdly complex arrangement of six stars in orbit around one another, in order to measure their masses once and for all.
Protoplanetary disks don’t exist in isolation; when young stars pass each other by, their gravitational encounter can disrupt, or maybe even kickstart, planet formation.
