An Icy Disk in the Orion Nebula

The heart of the Orion Nebula, near the massive young stars of the Trapezium Cluster, is a dramatic place for a star to grow up. New research examines JWST images of an unusual protoplanetary disk in this exceptional setting.

Life Is Like a Box of Potential Biosignatures

Astrobites reports on how habitable exoplanets resembling Earth in its younger years might appear to the Habitable Worlds Observatory.

eighteen images of supernova remnant SN 1987A's equatorial ring

A ring of bright “hotspots” adorns the remnant of the supernova SN 1987A. Now, researchers have analyzed two decades of Hubble Space Telescope observations to track the evolution of this ring.

galaxy merger

Across cosmic time, galaxies interact and merge with each other, causing disruptions in their behavior. Recent simulations explore the impacts interactions have on the star formation activity in interacting galaxies.
