Jan. 13, 2023 —A team has studied the relation between galaxy size and luminosity of some of the earliest galaxies in the universe taken by the James Webb Space Telescope, less than a billion years after the Big ...
June 8, 2021 —Astrophysicists have developed a new method for pinpointing the whereabouts of extremely rare extragalactic objects. They hope their technique for finding 'changing-look quasars' will take ...
Sep. 29, 2022 —Researchers have implemented a ground-breaking algorithm for reconstructing particles at the Large Hadron Collider. The project is part of the Compact Muon Solenoid (CMS) experiment -- one of seven ...
May 19, 2023 —Researchers have observed the X-ray emission of the most luminous quasar seen in the last 9 billion years of cosmic history, known as SMSS J114447.77-430859.3, or J1144 for short. The new perspective ...
Sep. 6, 2021 —As their name suggests, ultradiffuse galaxies, or UDGs, are dwarf galaxies whose stars are spread out over a vast region, resulting in extremely low surface brightness, making them very difficult to ...
June 12, 2023 —fo新模拟提供了新的解释r star's 85-year flare. In this scenario, a young giant planet is burning up very close to its star, suggesting solar systems may have hosted many of such ...
Apr. 7, 2022 —An international team of astronomers has spotted the most distant astronomical object ever: a galaxy. Shining only approximately 300 million years after the Big Bang, it may be home to the oldest ...
Nov. 30, 2022 —Astronomers discover a bright optical flare caused by a dying star's encounter with a supermassive black ...
Nov. 9, 2020 —Scientists have developed new simulations of black holes with widely varying masses merging that could help power the next generation of gravitational wave ...
Apr. 6, 2023 —Of the many different kinds of stars, asymptotic giant branch (AGB) stars, usually slightly larger and older than our own sun, are known producers of interstellar dust. Dusty AGBs are particularly ...
