James Webb Space Telescope Uncovers Overlapping Jets and a Golden Cavity in NGC 7129

Photo credit: NASA/Chris GunnNASA’s James Webb Space Telescope turned its near-infrared camera toward a dusty patch of the constellation Cepheus and returned an image of NGC 7129 that lays out several stages of star formation across a single frame. Roughly 3,300 light-years from Earth, the region spans about 5.7 light-years and holds both young stars […]

Webb Places the Farthest Fast Radio Burst Inside a Tiny Young Galaxy

On March 4, 2024, a radio array in South Africa caught a flash that lasted only a few milliseconds and then vanished. MeerKAT, working with the MeerTRAP search system, logged it at 00:50 UTC and gave it the name FRB 20240304B. The pulse arrived stretched and delayed by free electrons along the path, with a […]

James Webb Finds Two Rare Gravitational Mirrors in Cluster MACS J0454.1-0300

Golden elliptical galaxies fill the middle of the newest James Webb Picture of the Month, released this morning. They belong to the cluster MACS J0454.1-0300. Orange galaxies crowd one side of the frame and stretch into a broad arc around the brightest central members, while smaller reddish objects bend into short arcs even near the […]

Webb Showcases How IRS 3 Still Makes Dust and Water 0.55 Light-Years From Sagittarius A*

Webb’s NIRCam and MIRI cameras filled a 2.5-by-1.8-arcminute frame with the inner parsec of the Milky Way, a packed star field 26,000 light-years away in Sagittarius. IRS 3 sits in that crowd, a cool, luminous asymptotic giant branch star only 0.55 light-years from Sagittarius A*, the four-million-solar-mass black hole at the center of the galaxy. […]
