Selections from 2025: Hubble Observes 3I/ATLAS
The third interstellar object to enter our solar system, 3I/ATLAS, is without a doubt one of the most fascinating astronomical discoveries of this year.
Intergalactic Impacts of Quasars During the Epoch of Reionization
A recent study with JWST has unveiled how a reionization-era quasar has suppressed star formation in its galactic neighbors.
A Unified Explanation for Fast Radio Bursts
Researchers examine the possibility that one-off and repeating fast radio bursts could both arise from magnetars.
Michelangelo in Space: A Planet Carving the Fomalhaut Debris Disk?
Astrobites reports on the Fomalhaut debris disk, which is well studied but may contain a hidden planet we haven’t seen yet.
Featured Image: Studying the Space Weather of Young Suns
An ongoing survey aims to detect bursts of radio emission associated with flares and coronal mass ejections from young Sun-like stars.
Investigating the Most Luminous Known Fast Blue Optical Transient
AT2024wpp is the most powerful fast blue optical transient spotted so far. What do extensive X-ray and radio observations tell us about this event?
Boosting the Gravitational Wave Background
Researchers show how preferential accretion in a merging pair of supermassive black holes can explain the unexpectedly large amplitude of the gravitational wave background.
Bumpy Road Ahead: Can Binary Interactions Make Supernovae Periodically Brighter?
Astrobites reports on simulations that explore whether a baby neutron star repeatedly diving into the envelope of its inflated companion star could be the cause of bumpy supernova light curves.
How Solar Flares Hint That They’re About to Happen
Researchers have investigated how solar flares might signal that they’re about to occur and whether they’ll be accompanied by an explosion of plasma.
