An independent study shows how NASA can help understand unidentified anomalous phenomena, more colloquially known as UFOs.
A newfound cosmic alignment of galaxies challenges fundamental ideas about the nature of our universe.
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.
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.
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.
Astronomers have spotted the first solid evidence for a planetary Trojan body forming in another system outside our own.
The intrepid infrared explorer is offering astronomers a jump back in time, enabling them to see quasars at earlier times than ever before.
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).
In the JWST version of the Hubble Deep Field, astronomers are discovering what galactic life was like in the earliest years of the universe.
Massive, dying stars — behemoths tens of times the Sun's mass — should emit gravitational waves that we can hear with LIGO.
The Daniel K. Inouye Solar Telescope shows some stunning detail on the Sun, including sunspots, fibrils, granules, and other solar textures.
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.
The first stars are too faint and far away to detect directly, but their gaseous remains can be seen absorbing the light of distant galaxies.
