Featured Image: Hunting for Missing Supernova Remnants with EMU and POSSUM
Our galaxy likely contains far more supernova remnants than we’ve found so far. What progress have recent radio surveys made in the hunt for supernova remnants?
Featured Image: Mother’s Day Superstorms
In May 2024, the Sun put on a powerful display of solar storms, and researchers have examined the source of all this activity to understand why.
Featured Image: Low-Mass Brown Dwarfs in a Class of Their Own?
JWST observations of the young star cluster IC 348 revealed extremely low-mass brown dwarfs with signatures of hydrocarbons in their spectra: meet the members of the proposed “H” spectral class.
Featured Image: Hubble and JWST Check Up on the BOAT Gamma-Ray Burst
Two powerful telescopes examined the brightest gamma-ray burst ever observed by humans, hundreds of days after the burst was first detected. What did they see?
Featured Image: Following Photons Through Curved Spacetimes
A new fast and flexible ray-tracing algorithm aims to make the complex world of general relativistic magnetohydrodynamics simulations more approachable.
Featured Image: JWST Examines the Ring Nebula
New JWST images of the Ring Nebula reveal a dusty disk around the nebula’s central star — just the second resolved disk known around a planetary nebula’s central star.
Featured Image: The Last Asteroid Pair Discovered by Arecibo
The 1,000-foot-wide Arecibo Telescope discovered nearly 60 binary or triple asteroid systems. 2020 BX12 was the final binary asteroid discovered with Arecibo before the telescope collapsed in 2020.
Featured Image: Rare Double Radio Relic
What at first appeared to be an unremarkable low-mass galaxy cluster has been revealed to host a rare pair of parenthesis-shaped radio sources.
Featured Image: Details of a Rare Ejecta Nebula
New images highlight the clumpy ejecta and radial streaks surrounding WR 8, a Wolf–Rayet star that may be changing from one spectral subclass to another.
