Arboreal Astronomers: Using Tree-Rings to Probe Solar Activity
Humans aren’t the only things that track evidence of cosmic history. See how modern astronomers use ancient tree-rings to investigate solar activity!

Can machine learning and photometry help us uncover water on distant planets? Read on to find out!
Today’s authors use orbital measurements to dynamically “weigh” a group of galaxies. Read on to learn about this method and how the Centaurus A group may be missing some matter!
Was Einstein right that experiments behave the same in deep space as in an elevator freely falling on Earth, or does the gravity in the latter case matter? Find out about an observational test in today’s guest post by Indranil Banik.
Ever wanted to estimate some cosmological parameters but your MCMC chains are too slow? Check out today’s paper for a method to speed up your estimation using iterative emulation.
With an ideal dataset of many localized FRBs, how can the diffuse gas fraction in the IGM be constrained?
