A New View of the Spectroscopic Universe
More than a quarter century ago, the Sloan Digital Sky Survey fundamentally changed the way modern astronomy research is done. The collaboration recently released their summary of the fifth generation of their landmark survey.
Recent work explores whether a commonly assumed source of data–model disagreement in simulations of stellar interiors is really to blame.
Feed the Fire, Fade the Metals
Astrobites reports on whether cosmic clumps are “homegrown” or fueled by fresh inflows.
Are galaxies that travel through space in groups any different from those that fly solo? A new look at local galaxies provides clues.
Gas flowing into a galaxy is hard to detect, but a recent study simulated a dusty galaxy to understand how we might be able to uncover inflows with emission line ratios.
A Black Hole’s Puzzling X-Ray Bursts
A supermassive black hole awakened seven years ago, and it’s now behaving in a way astronomers can’t explain.
The Oldest Starlight
Astrobites reports on whether JWST’s most extreme high-redshift galaxy candidates aren’t galaxies at all, but the explosive deaths of the very first stars.
Monthly Roundup: Science of the Sun
Researchers search for the tiniest coronal jets, explore the Sun’s behavior from centuries ago, and examine space weather forecasts in this month’s Roundup.
How Galaxies Grow Up
A massive survey of images collected by JWST is shedding light on how galaxies grow and evolve.
