This extreme star might have huge tidal waves
Gravitational forces between two orbiting stars might be creating huge waves of plasma on one of the stars that break and crash to the surface.

JWST’s hunt for distant galaxies keeps turning up surprises
In its first year, the James Webb Space Telescope has found many galaxies from the early universe that are bigger, brighter and more mature than expected.

Recoiling black holes could move at nearly one-tenth the speed of light
Knowing black holes’ speed after being kicked by gravitational waves can reveal how much energy converging black holes can release.

Meet Jane Rigby, senior project scientist for JWST and advocate for LGBTQ+ astronomers
Rigby, senior project scientist for the James Webb Space Telescope, believes being part of the LGBTQ+ community has made her a better astronomer.

Spiral galaxies might have been lentil-shaped before becoming starry whirls
By using black holes to track how galaxies merge and grow, an astronomer has proposed an update to the prevailing story of how galaxy shapes evolve.

50 years ago, mysterious glass hinted at Earth’s violent past
Like Hansel and Gretel followed a trail of breadcrumbs, scientists have followed tektites to the sites of major meteorite impacts.

The James Webb telescope may have spotted stars powered by dark matter
Three objects in the distant universe bear signs of hypothesized “dark stars,” researchers claim, though others say more definitive data are needed.

How an ancient solar flare illuminated the start of the Viking Age
Improved radiocarbon dating aided by a solar flare in the year 775 sheds light on the early days of Vikings and global trading in medieval times.

NASA’s DART mission lofted a swarm of boulders into space
Hubble telescope images of the asteroid Dimorphos reveal a halo of 37 dim, newfound objects — most likely boulders shaken loose from the surface.

Centuries on, Newton’s gravitational constant still can’t be pinned down
A new experiment could finally answer the question 'What is the strength of gravity?' But it's a hard test to do.

Granite likely lurks beneath the moon’s surface
Without plate tectonics or water, granite is hard to make. But a 50-kilometer-wide hunk sits beneath the moon’s surface, lunar orbiter data suggest.

A rain of electrons causes Mercury’s X-ray auroras
The first direct measurement of electrons raining down on Mercury suggests this particle precipitation causes most auroras in the solar system.
