In the star-forming region IC 348, about 1,000 light-years away, Webb has spotted an object barely twice Jupiter's mass — the lightest brown dwarf candidate known. It's forcing astronomers to rethink where planets end and stars begin.
Newborn star clusters are wrapped in gas cocoons and invisible in optical light. A team led by Stockholm University combed through thousands of clusters with Hubble and JWST and found that massive clusters break free in about 5 million years, while lighter ones take 7 to 8 million — and the heavier ones are the first to light up their galaxy. SORABUMI explains.
About 200,000 light-years away, in a corner of the Small Magellanic Cloud, NGC 602 is a star cluster where the death of massive stars and the birth of new ones play out in the same place, at the same time. What JWST and Chandra captured together looks like a cosmic wreath — and it doubles as a window into what the early universe was like.
The spiral galaxy M88, 63 million light-years away, is losing its gas as it plows through the Virgo Cluster. Hubble's observations of this "ram pressure stripping" reveal the mechanism that decides a galaxy's fate — explained clearly.
