Physicists dispute a claim of detecting a black hole’s ‘photon ring’
A thin ring of light around a black hole, which would probe gravity in a new way, has been found, one team claims. Skeptics aren’t convinced.

The James Webb telescope spotted CO2 in an exoplanet’s atmosphere
The first definitive detection of the gas on a world in another solar system paves the way for detections in planets that are more Earthlike.

The discovery of the Kuiper Belt revamped our view of the solar system
Thirty years ago, astronomers found the Kuiper Belt, a region of space home to Pluto and other icy worlds that helped show how the solar system evolved.

Not one, but two asteroids might have slain the dinosaurs
A craterlike structure found off West Africa’s coast might have been formed by an asteroid impact around the same time the dinosaurs went extinct.

Oort cloud comets may spin themselves to death
How icy objects from the solar system’s fringe break up as they near the sun is a long-standing mystery. One astronomer now thinks he has an answer.
- Planetary Science
Asteroid impacts might have created some of Mars’ sand
Roughly a quarter of the Red Planet’s sand is spherical bits of glass forged in violent impacts, new observations reveal.

Over time, Betelgeuse changed color. Now it’s also lost its rhythm
A recent upset to the star’s variability and ancient records that describe the red star as yellow tell a tale of a star that is no stranger to change.

Scientists mapped dark matter around galaxies in the early universe
A technique used to reveal dark matter could also shed light on a disagreement about the clumpiness of matter in the cosmos.

Mini-Neptunes may become super-Earths as the exoplanets lose their atmospheres
Starlight is eroding the atmospheres of a handful of gassy exoplanets that are a bit smaller than Neptune, gradually exposing the rocky cores within.
