Magnetars are observationally rare, highly magnetic neutron stars, potentially arising from core-collapse supernovae. However, other origins have been suggested: stellar mergers or an induced collapse within a progenitor binary system….

Surprisingly faint first galaxies | Nature Astronomy
A puzzling feature of cosmic dawn is that bright galaxies in the redshift range 10 < z < 15 are overabundant relative to HST-based expectations but have so far evaded detection at higher redshifts, despite JWST’s technical capacity to do so….

The Resonant Remains of Broken Chains from Major and Minor Mergers
TESS and Kepler have revealed that practically all close-in sub-Neptunes form in mean-motion resonant chains, most of which unravel on timescales of 100 Myr. Using N-body integrations, we study how planetary collisions from destabilized resonant…

Missing link in early Martian water cycle discovered
Billions of years ago, water flowed on the surface of Mars. But scientists have an incomplete picture of how the Red Planet’s water cycle worked.
That could soon change after two graduate students at The University of Texas at Austin filled a…

Galaxy Clusters Should Be Cold – XRISM Just Found Out Why They’re Not
Astronomers may have finally cracked one of the universe’s long-standing puzzles: why galaxy clusters remain mysteriously warm despite constantly losing energy through X-rays. Using Japan’s XRISM satellite, scientists observed a fast,…
