Sensing Suns: Astronomers Accurately Measure the Temperature of Red Supergiant Stars
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…
Planetary scientists wondered if bands of winds or swirling storms dominated the atmospheres of brown dwarfs. University of Arizona-led research has solved the mystery. A…
Astronomers have recently found the fastest spinning and possibly the youngest magnetar known. This object, known as J1818.0-1607, is located about 21,000 light years away…
A research team, led by astronomers from National Astronomical Observatories of Chinese Academy of Sciences (NAOC), has discovered 591 high velocity stars from the Large…
How stars form in galaxies remains a major open question. Robert Feldmann sheds new light on this topic with the help of a data-driven re-analysis…
Researchers may have found the long-sought “nanoflares” thought to heat the solar corona to its incredible temperatures. A new study published in Nature Astronomy marks…
An international research team led by the University of Bern has discovered an exotic binary system composed of two young planet-like objects, orbiting around each…
