Meet the Progenitor of the Latest Nearby Supernova
Supernova hunters have been busy: SN 2024ggi is the second nearby supernova in less than a year. What do archival observations tell us about this supernova’s progenitor star?
A New Way to Grow a Supermassive Black Hole
Simulations suggest that black holes could have grown to supermassive size with the help of young star clusters in the early universe.
The Curious Case of Twin Fast Radio Bursts
A pair of nearly identical fast radio bursts from different sources gives a hint to the cause of these powerful radio flashes.
Hot Stars Spin Sideways
Most cool stars spin nicely aligned with their planets. So why do their hot counterparts tumble in nearly random directions?
A Type Ia Supernova in an Unusual Place
The supernova SN 2019ein may have originated near a globular cluster — an unusual environment that hints to the nature of the supernova progenitor system.
Signs of the First Stars in a Distant Galaxy
Meet RX J2129–z8He II: a remarkable high-redshift galaxy that might be home to some of the first generation of stars.
It’s Just a Phase: Dark Matter–Dominated Galaxies in the Early Universe
Billions of years ago, small galaxies may have had cores packed with dark matter. What would these galaxies look like today?
Dimorphos, from Up Close and Far Away
A recent study merges different datasets to build a richer picture of Dimorphos, humanity’s first asteroid redirection target.
Monthly Roundup: The Allure of Temperate Exoplanets
This month, we’re exploring temperate exoplanets: how to find them, how to model them, and how to figure out if they host life.
