Astronomers tracking a nearby star system thought they had spotted an exoplanet reflecting light from its star. Then it vanished. Even stranger, another bright object appeared nearby.
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have discovered chemical fingerprints of primordial stars weighing between 1,000 and 10,000 times the mass of the Sun in GS 3073,an early galaxy.
Two stars, now located some 400 to 500 light-years from Earth, swung through our neighborhood on their journey through the Milky Way, coming as close as 32 light-years.
A galaxy formed around 11 billion years ago that appears to be "metal-free", indicating that it might contain a set of elusive first-generation (Pop III) stars.
Astronomers have detected a storm on a star other than our Sun for the first time, discovering an explosion so violent it could have stripped away the atmosphere of any planets unlucky enough to be nearby.
The finding suggests phosphine—a potential biosignature—shouldn’t be viewed as evidence of alien life until natural, non-biological sources are ruled out.
A new theory proposes that Population III.1 supermassive stars were progenitors of supermassive black holes in the early Universe.
In 2021, astronomers watched in astonishment as a supernova 2.2 billion light-years away named SN2021yfj bloomed, rich with silicon, sulfur, and argon – something never before seen in an exploding star.
About 70,000 years ago Scholz's star passed through the Oort Cloud. It may have perturbed some comets from the Oort Cloud. But we won't know for a couple of million years because that's how long it would take for a comet to reach us.
Binary star systems are pairs of stars held together by gravity, orbiting a common center of mass.
On May 6, 2025, an international team of astronomers using the W. M. Keck Observatory in Hawaii said it has listened to the “music” of a nearby star.
A celestial shadow known as the Circinus West molecular cloud creeps across this image captured with fabricated Dark Energy Camera - one of the most powerful digital cameras in the world.
Scientists have long been trying to determine how elements heavier than iron, including gold and platinum, were first created and scattered through the Universe, and new research may give us another part of the answer: magnetars.
The "music" of starquakes - enormous vibrations caused by bursting bubbles of gas that ripple throughout the bodies of many stars - can reveal far more information about the stars.
A recent study reveals that the famous Wolf-Rayet 104 "pinwheel star" holds more mystery but is even less likely to be the potential "death star" it was once thought to be.
