JWST resolves 16.5 million stars in Messier 82’s Cigar Galaxy and finds an early, densely packed star-forming environment incons

The James Webb Space Telescope used its infrared camera to resolve 16.5 million individual stars in Messier 82, attributing the bursty star formation to a galaxy merger. The observed stellar population implies star formation rates far above the Milky Way and a short-lived episode—estimated to persist only a few hundred million years.

JWST and ALMA observations suggest “galaxy-killing” merger-driven winds shut down star formation in early massive galaxies New James Webb Space Telescope and ALMA data point to a wind mechanism capable of suppressing star formation in some of the early universe’s most massive galaxies. The “galaxy-killing” outflows are linked to cosmic mergers, offering an explanation for why these systems “lived fast and died young.”

JWST “Little Red Dots” take shape: evidence they’re black-hole feeding bursts Astronomers using the James Webb Space Telescope report its strongest spectrum-based evidence yet that the early-universe “little red dots” may be black holes. A theoretical study further argues the objects could correspond to black hole feeding episodes occurring in rare nuclear bursts.

NASA’s Habitable Worlds Observatory planning: study tests how it could detect biosignatures in an “ancient Earth” atmosphere NASA is building the Habitable Worlds Observatory (HWO) to search for signs of life on nearby planets. A new study modeled whether HWO could confidently detect atmospheric biosignatures by comparing observations against an “ancient Earth” reference, focusing on the interpretability of biosignature signals.

Webb makes first direct measurement of a supermassive black hole in the early universe Using data from the joint NASA/ESA/CSA James Webb Space Telescope, an international team reports the first direct measurement of a supermassive black hole in the early universe, refining understanding of “Little Red Dots.” The result underscores Webb’s ability to capture high-redshift black hole signatures directly rather than infer them indirectly.

JWST is “sniffing” alien atmospheres as Habitable Worlds Observatory moves into construction to hunt for extraterrestrial biolog The James Webb Space Telescope is already probing potential signs of life by analyzing alien atmospheres, while the Habitable Worlds Observatory is being built specifically to search for biology beyond Earth. The shift underscores how JWST-era observations will feed into dedicated follow-on missions.

JWST study suggests Neptune’s moon Nereid is the lone intact survivor from the planet’s original satellite system A new study reports that Neptune’s third-largest moon, Nereid, may be an intact survivor from the planet’s primordial satellite system. Researchers used NASA’s James Webb Space Telescope to study Nereid in 2024, challenging earlier views of a more heavily disrupted past.
