Some of the oldest stars in the universe found hiding near the Milky Way's edge — and they may not be alone
By Harry Baker published
Astronomers reanalyzed the chemical composition of three stars in the Milky Way's halo and found that they are between 12 and 13 billion years old. They may have also been stolen from other galaxies.
Giant 'rogue waves' of invisible matter might be disrupting the orbits of stars, new study hints
By Paul Sutter published
New research shows how disruptions to binary star systems could be the key to detecting space's most confounding substance — dark matter.
Scientists find one of the oldest stars in the universe in a galaxy right next to ours
By Jonathan Gilbert published
An ancient star discovered in the Large Magellanic Cloud has revealed the chemical fingerprint of the early universe. It hints that conditions were not the same everywhere when the first stars forged the elements for life.
Gravitational waves reveal 1st-of-its-kind merger between neutron star and mystery object
By Sharmila Kuthunur published
Ripples in space-time point to the merger of a neutron star with another mystery object. The object, which falls right within the mass-gap range, sheds light on a long-sought, murky realm.
Immensely powerful 'magnetar' is emitting wobbly radio signals in our galaxy — and scientists can't explain them
By Harry Baker published
Strange radio signals coming from a magnetar that "woke up" after more than a decade of radio silence cannot be explained by our current understanding of the universe's strongest magnets, hinting at a puzzling new phenomenon.
Some stars may be 'infected' with black holes that destroy them from within, new study hints
By Jonathan Gilbert published
Could dark matter be made of mini black holes that formed in the early universe? One way to find out is to look for missing stars, destroyed by primordial black holes, a new study suggests.
Stars, planets and more will be visible during the total solar eclipse on April 8. Here's what to look for, and where.
By Joe Rao published
When the skies darken during the total solar eclipse on April 8, colors will change, and some stars and planets will be visible in the daytime. Here's what to look for, and where.
Study of 'twin' stars finds 1 in 12 have killed and eaten a planet
By Charles Q. Choi published
A study of 91 pairs of stars finds that about 8%, or one in 12, swallowed up a planet at some point in their lives.
Newly discovered 'fountain of youth' phenomenon may help stars delay death by billions of years
By Robert Lea published
Recent observations show that some white dwarf stars suddenly stop cooling. Now, scientists propose a 'fountain of youth' mechanism that may explain how these stellar husks avoid death for billions of years.
Speck of light spotted by Hubble is one of the most enormous galaxies in the early universe, James Webb telescope reveals
By Robert Lea published
The ancient obect Gz9p3, which appeared as a single point of light through the Hubble Space Telescope, is actually one of the most enormous galaxies in the early universe, James Webb Space Telescope observations reveal.
