This week in science: JWST pushes star-like formation to two Jupiter masses, LIGO reveals quantum back-action on 40-kilogram mirrors, WASP-12 b loses hydrogen into space, and Chandra uncovers 84 hypersoft X-ray sources.

This week in science: JWST’s little red dots may be quasi-stars around growing black-hole seeds, Gaia measures the Milky Way’s slow disk tilt, IceCube constrains one LUX-ZEPLIN dark-matter explanation, and Spectrum reaches orbit from Europe.

Roman heads toward L2 as a quantum free-fall test supports Einstein, dark-matter detectors enter the neutrino fog, and X-rays hint at a 0.16c black-hole inflow.

This week in science: S301 races around Sagittarius A* at more than 8% of light speed, REBELS-25 reveals an unexpectedly mature early galaxy, JWST probes a reflective lava-world atmosphere, and ancient nova shells may surround U Geminorum.

Webb’s Lion Nebula, a lunar rocket impact, new IMAP data, and a plan to boost NASA’s Swift observatory lead this week’s space science roundup.

New research suggests the Sun’s most extreme X100 flares may be far rarer than simple extrapolations imply, while new observations reveal hidden magnetic structure, an accretion-disk wind, and a stable galaxy-rotation relation.

Curiosity maps its largest field of Martian polygonal fractures, while Landsat records Western Europe’s fires and NASA previews August skywatching.

eROSITA nearly doubles the known X-ray source population, while Rubin opens a deep COSMOS data preview and an AI scheduler directs a major telescope.

Webb links mysterious little red dots to obscured black holes, while August brings a solar eclipse, the Perseids, bright Venus, and a lunar eclipse.
