NASA Finds No Evidence UFOs Are Extraterrestrial, Promises Further Study
An independent study shows how NASA can help understand unidentified anomalous phenomena, more colloquially known as UFOs.

Galaxies Outline Bubble 1 Billion Light-Years Wide in Space
A newfound cosmic alignment of galaxies challenges fundamental ideas about the nature of our universe.

Peculiar Pulsar Throws “Cosmic Cannonballs”
Astronomers think a city-size star that’s spinning faster than a kitchen blender is shooting out plasma torpedoes.

Astronomers Find Strange Star Is a Powerful Magnet
Astronomers have found a star that has a magnetic field rivaling the strongest magnet humans have ever built — and it might explain the origin of highly magnetic cinders known as magnetars.

Webb Views the Ring Nebula and Earendel in a New Light
This week, James Webb Space Telescope reveals new details in the Ring Nebula and shows that the most distant known star isn't alone. Meanwhile, patient astronomers have collected 17 years' worth of images of the super-Jupiter Beta Pictoris b.

Images capture the birth of stars and planets in multiple results from space- and ground-based telescopes.

Kite-like Galaxy Trails a Million-light-year String of Gas and Star-forming Knots
A galaxy 600 million light-years away appears to be trailing gas in a string 1.2 million light-years long, but explaining its origins presents a challenge.

This Planet Might Have a Sibling Sharing Its Orbit
Astronomers have spotted the first solid evidence for a planetary Trojan body forming in another system outside our own.

Exoplanet News: No Air on Venus Twin, Young Jupiter Discovery
Astronomers have discovered Jupiter's younger sibling in a system 88 light-years away. Meanwhile, only 40 light-years away, a Venus-size world turns out to be airless (or nearly so).

Even Lonely Black Holes Need to Eat
Astronomers have found supermassive black holes in smaller galaxies are actually more likely to light up when they’re isolated in vast, cosmic voids.

How Soon Will Betelgeuse Blow?
A new study making the rounds predicts that supergiant Betelgeuse will explode as a supernova sooner rather than later, but others are urging caution.

James Webb Space Telescope Uncovers Hundreds of Galaxies in Early Universe
In the JWST version of the Hubble Deep Field, astronomers are discovering what galactic life was like in the earliest years of the universe.

We Could Soon “Hear” the Gravitational Waves of Dying Stars
Massive, dying stars — behemoths tens of times the Sun's mass — should emit gravitational waves that we can hear with LIGO.

The Sun Gets Its Close-up: Images from New Solar Telescope
The Daniel K. Inouye Solar Telescope shows some stunning detail on the Sun, including sunspots, fibrils, granules, and other solar textures.

Replay of Star’s Death Sheds Light on Universe’s Expansion
A cosmic lens magnified the light of an exploding star. Now, astronomers are using observations of that supernova to calculate the universe’s current rate of expansion.
