The Sloan Digital Sky Survey: A Legacy
Today’s ‘beyond’ bite takes you back to 2000, when a new telescope meant to survey the night sky takes the astrophysics community by storm.
Our halo is getting younger, spatially speaking
The halo of the Milky Way is old. You’ve probably heard that a million times. But can we know more about its age than simply “it’s old”? Yes, we can — and that leads to interesting results!

The Great Wall (of Galaxies, in Sloan)
The largest structures of the universe lie within.
The Trouble with H0 (or not?)
Theres trouble brewing in the field of cosmology, as astrophysicists attempt to understand the latest measurements of the Hubble constant.
Probing the Galaxy with Dead Stars

Hypervariables in the nucleus of galaxies
A search expedition on the lookout for tidal disruption events led to something else altogether.
