The unexpected behavior of pulsing stars could help us measure the universe
New research offers the most precise measurements yet of pulsating Cepheid stars, which could reveal new clues about the immense size and scale of our universe.
A 'new star' will appear in the sky any night now. Here's how to watch the Blaze Star ignite.
The "Blaze Star" T Coronae Borealis is expected to erupt with a magnificent explosion sometime between now and September, becoming visible to the naked eye. Here's how to find it when it does.
James Webb telescope reveals long-studied baby star is actually 'twins' — and they're throwing identical tantrums
New observations from the James Webb Space Telescope revealed that a distant protostar is actually a pair of baby binary stars that are spitting out parallel energy jets as they gobble up giant disks of gas and dust.
Three bright stars mark the beginning of summer. Here's how to spot the 'Summer Triangle' this week.
The appearance this week of the three bright Summer Triangle stars — Vega, Deneb and Altair — marks the beginning of summer in the Northern Hemisphere. Here's how to spot them.
NASA will put a 'new star' in the sky by the end of the decade in 1st-of-its-kind mission
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.
'Vanishing' stars may be turning into black holes without going supernova, new study hints
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.
Alien 'Dyson sphere' megastructures could surround at least 7 stars in our galaxy, new studies suggest
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.
Some of the oldest stars in the universe found hiding near the Milky Way's edge — and they may not be alone
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
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
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.
