A curiously yellow pre-supernova star has caused astrophysicists to re-evaluate what’s possible at the deaths of our Universe’s most massive stars. The team describes the…
Scientists have spotted the largest flare ever recorded from the sun’s nearest neighbor, the star Proxima Centauri. The research, which was published recently in The…
Stars spin faster than expected as they age according to a new study led by scientists at the University of Birmingham which uses asteroseismology to…
Discovery a ‘coup’ in astrophysics involving observations with nine instruments. A team of astronomers including Carnegie’s Alycia Weinberger and former-Carnegie postdoc Meredith MacGregor, now an…
An international team of researchers led by ETH Zurich has reconstructed solar activity back to the year 969 using measurements of radioactive carbon in tree…
The red hypergiant VY Canis Majoris is enshrouded in huge clouds of dust Stars come in an extraordinary range of sizes. One of the most…
Red supergiants are a class of star that end their lives in supernova explosions. Their lifecycles are not fully understood, partly due to difficulties in…
Gaia survey provides location and motion of 1.3 million binary pairs within 3,000 light years of Earth. The latest star data from the Gaia space…
An international team of scientists has discovered planet formation in a star system younger than 500,000 years old. The find, published in Nature, is a…
Remnants of planets with Earth-like crusts have been discovered in the atmospheres of four nearby white dwarf stars by University of Warwick astronomers, offering a…
Using observations from NASA’s Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a trio of hot worlds larger than Earth orbiting…
Recalibrated Betelgeuse’s mass, radius, and distance. Betelgeuse is normally one of the brightest, most recognizable stars of the winter sky, marking the left shoulder of…
Galaxies begin to “die” when they stop forming stars, but until now astronomers had never clearly glimpsed the start of this process in a far-away…
The Pleiades star cluster, a brilliant collection of several hundred stars visible in the winter sky near the constellation of Orion, has been admired by…
Examination of Theia 456 finds its nearly 500 stars were born at same time. The Milky Way houses 8,292 recently discovered stellar streams — all…
Rare Star’s Giant Gamma-Ray Burst GRB 204015A Captured Close to Our Home Galaxy Earth gets blasted by mild short gamma-ray bursts (GRBs) most days. But…
Astronomers have looked nine billion years into the past to find evidence that galaxy mergers in the early universe could shut down star formation and…
This image shows a new type of star that has never been seen before in X-ray light. This strange star formed after two white dwarfs…
