July 31, 2023 — Researchers offer insight into the source of cosmic magnetic fields. The research team used models to show that magnetic fields may spontaneously arise in turbulent plasma. Their simulations showed ...
Sep. 6, 2022 — Jupiter-sized planets can be stolen or captured by massive stars in the densely populated stellar nurseries where most stars are born, a new study has ...
Aug. 27, 2021 — Brown dwarfs are astronomical objects with masses between those of planets and stars. The question of where exactly the limits of their mass lie remains a matter of debate, especially since their ...
Oct. 19, 2020 — Astronomers at the University of Iowa have determined our galaxy is surrounded by a clumpy halo of hot gases that is continually being supplied with material ejected by birthing or dying stars. The ...
May 11, 2023 — Globular clusters are the most massive and oldest star clusters in the Universe. They can contain up to 1 million of them. The chemical composition of these stars, born at the same time, shows ...
July 19, 2021 — Black holes with masses equivalent to millions of suns do put a brake on the birth of new stars, say astronomers. Using machine learning and three state of the art simulations to back up results from ...
Dec. 17, 2020 — Astrophysicists have for the first time observed a gas filament with a length of 50 million light years. Its structure is strikingly similar to the predictions of computer simulations. The ...
May 24, 2021 — Three dozen dwarf galaxies far from each other had a simultaneous 'baby boom' of new stars, an unexpected discovery that challenges current theories on how galaxies grow and may enhance our ...
Nov. 6, 2020 — Astrophysicists consider that around 40% of the ordinary matter that makes up stars, planets and galaxies remains undetected, concealed in the form of a hot gas in the complexe cosmic web. Today, ...
Apr. 25, 2023 — Scientists have unlocked one of the biggest mysteries of quasars -- the brightest, most powerful objects in the Universe -- by discovering that they are ignited by galaxies ...
