Multi-messenger constraints on the Hubble constant
The Hubble tension remains a major open question in contemporary cosmology. Today’s paper addresses using gravitational waves and light from neutron star mergers to constrain the Hubble constant.
How Pulsating Stellar Flares Shape the Prospects for Life on Distant Planets
Pulsating flares on M dwarfs can disrupt the atmospheres of exoplanets. However, in just the right amounts, they could be the genesis of primordial life. Today’s paper describes how!

Breaking the Stigma around Community College: an astro[sound] bite
For many students, community college is part of their undergraduate education. We take a look at what community college is, the perception of a community college student, and share experiences from a few astronomers that started undergrad at a community college.
UR: GRBs – New Standard Candles for Cosmology
Hyper accreting black holes? Highly magnetised neutron stars? What is behind the most powerful explosions in space and how can we use them to measure the largest distances? Recently published population study of gamma-ray bursts light curves that addresses these questions.
UR: Matching Supernova Progenitors to their Fingerprints
In the latest of our #UndergradResearch series, Mckenzie Ferrari compares real optical supernova spectra to models to identify their progenitors.
