NASA says the Nancy Grace Roman Space Telescope is scheduled to launch Aug. 30 aboard a SpaceX Falcon Heavy. The observatory will travel nearly 1 million miles from Earth to reach the same orbital “sweet spot” as the James Webb Space Telescope, enabling wide-field science aimed at discoveries currently impossible from existing assets.

NASA says the Nancy Grace Roman Space Telescope is scheduled to launch Aug. 30 aboard a SpaceX Falcon Heavy. The observatory will travel nearly 1 million miles from Earth to reach the same orbital “sweet spot” as the James Webb Space Telescope, enabling wide-field science aimed at discoveries currently impossible from existing assets.
ESA’s Euclid space telescope has spotted 31 ancient quasars—among the oldest and most remote objects observed—using their redshifted light to peer into the dawn of the Universe. The findings include the earliest quasars ever identified and add new constraints on how the first galaxies formed and evolved.
NASA’s James Webb Space Telescope used unprecedented near- and mid-infrared sensitivity to penetrate Centaurus A’s dust lanes, revealing a densely packed, active, and changing galaxy shaped by a cosmic collision. Separate JWST findings identify early-universe “little red dots” that may conceal black holes firing high-energy neutrinos through space.
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.
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.”
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 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.
High activity
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.
