The newly announced Landolt NASA Space Mission will launch a bread box-size "artificial star" satellite that will mimic stars by shining lasers directly at ground-based telescopes. This will enable astronomers to fine-tune instruments and potentially revolutionize how we study the universe.

Stars that vanish from the sky may be collapsing directly into black holes without going supernova first, a new study of a bizarre binary star system suggests.

Researchers have identified at least seven stars in our galaxy that may be surrounded by super-advanced alien megastructures, known as Dyson spheres. However, this is not the only explanation for these stars.

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.

New research shows how disruptions to binary star systems could be the key to detecting space's most confounding substance — dark matter.

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.

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.

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.

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.

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.
