James Webb shows what a dark super-Earth looks like with no air

The James Webb Space Telescope turned toward LHS 3844 b and drew a blunt conclusion from its thermal signal: this is a dark, bare rocky world without an atmosphere.

JWST may put the black hole before the galaxy in an early-universe puzzle

JWST has reopened an uncomfortable question in early cosmology: what if some supermassive black holes did not wait for their galaxies to mature, but became the system’s gravitational core first?

Webb Finds a Black Hole That Breaks the Early-Galaxy Timeline

The James Webb Space Telescope has caught the early Universe in an awkward frame: a black hole that looks too large, too early, and possibly older than its own galaxy.

James Webb reads the universe before stars had fully enriched it with heavier elements

An international team led by Kimihiko Nakajima of Kanazawa University used JWST and gravitational lensing to sharpen one of the most chemically primitive galaxies seen in the early universe.

Webb telescope turns the young cosmic web into a test of galaxy growth

COSMOS-Web uses JWST’s infrared reach to turn the early cosmic web from an impressive image into a structure astronomers can measure.

A barely visible early galaxy may carry the ash of the first stars

The James Webb Space Telescope has captured LAP1-B, a galaxy about 13 billion light-years away, that looks like one of the cleanest traces of the early universe.

A small planet survived the trip with a hot Jupiter and made migration harder to explain

JWST's analysis of TOI-1130b suggests the mini-Neptune formed far from its star and migrated inward with a hot Jupiter.

Uranus’s faint rings may be a map of moons we still cannot see

Uranus’s faint outer rings show patterns that may have been shaped by the gravity of small moons not yet directly observed.

The Black Hole Desert Debate: A Gap in Stellar Evolution

Three independent studies published this year clash over a 2.5–5 solar mass range where black holes seem to vanish—yet no one agrees why.

A planet with a 37-hour year could show how much air survives around red dwarfs

TOI-4616 b orbits an M4 dwarf 91.8 light-years away, giving astronomers a nearby lab for hot rocky atmospheres.
