James Webb Space Telescope
This image from Webb’s MIRI (Mid-Infrared Instrument) shows the star system Beta Pictoris. An edge-on disk of dusty debris generated by collisions between planetesimals (orange) dominates the view. A hotter, secondary disk (cyan) is inclined by about 5 degrees relative to the primary disk. The curved feature at upper right, which the science team nicknamed…

Astronomers solve mystery of ‘Green Monster’ in famous supernova remnant (photo)
The bizarre, grinch-like wisp of green light dubbed the Green Monster, first seen last year snaking through the glowing remnants of an exploded star, belongs to a blast wave bordering the debris field, a new study reveals. Last April, NASA’s James Webb Space Telescope (JWST or Webb) photographed the unusual “wall of emission” in front…

Space Oddity: Uncovering the Origin of the Universe’s Rare Radio Circles
Newswise — It’s not every day astronomers say, “What is that?” After all, most observed astronomical phenomena are known: stars, planets, black holes and galaxies. But in 2019 the newly completed ASKAP (Australian Square Kilometer Array Pathfinder) telescope picked up something no one had ever seen before: radio wave circles so large they contained entire…
