Over time, the universe evolved from a primordial soup of hydrogen and helium into the metal-rich environments of today. How exactly does the chemistry of galaxies evolve, and what processes drive this evolution?
Today’s paper ventures into the realm of Astronomy Education Research, unpacking how students in ASTRO 101 courses think about the shape of the universe.
Everyone wants to find a habitable planet. The authors of today’s paper make a compelling case that the HR 5183 system is not the best place to look.
Chemical tagging is the idea that using the chemistry of stars we can reconstruct their birth clusters. But can it actually be done?
Pulsar timing arrays could localise individual sources of gravitational waves to host galaxies. The problem is, it’s so computationally difficult! This paper shows us a faster way.
Today’s authors look for the origin of the blobby neutrino emission IceCube sees in the Milky Way!
