Bedtime Astronomy

James Webb has found a rocky super-Earth that appears to retain an atmosphere despite orbiting extremely close to its star. Its unexpectedly cool dayside may reveal how gases survive on scorching lava worlds—and could offer clues about Earth’s own molten past.

Did the universe twist its oldest light as it traveled across billions of years? Scientists have developed a new calibration method to test cosmic birefringence and separate genuine cosmic signals from telescope errors.

Using Planck data, the technique strengthens the case for a mysterious rotation that could point to new physics or dark matter.

The James Webb Space Telescope has found evidence that early galaxies were already producing and spreading heavy elements just 500 million years after the Big Bang.

Carbon and oxygen detected in distant galaxies suggest the young universe became chemically enriched much faster than expected, challenging the idea of a pristine early cosmos. The discovery also narrows the window for finding the universe’s first stars and reveals how rapidly the earliest galaxies evolved.

Researchers from the University of Hong Kong and Beijing Normal University have developed a new way to investigate dark matter by simulating its behavior as a wave.

Their 3D models of “fuzzy” dark matter reproduced the gravitational lensing of a distant quasar more accurately than previous approaches, revealing interference patterns that could help distinguish wave-like dark matter from conventional models. The work offers a new way to probe what may make up most of the universe’s matter.

Astronomers using the XRISM X-ray observatory have captured rare details of a neutron star feeding on the powerful stellar wind of a massive blue hypergiant 13,000 light-years away.

The observations reveal plasma racing toward the neutron star at about 335,000 mph, creating intense X-ray flares and a turbulent accretion disk. The discovery offers an unprecedented look at how matter behaves under extreme gravity and how some of the universe’s most
