Aug. 3, 2023 NASA's James Webb Space Telescope has recorded breath-taking new images of the iconic Ring Nebula, also known as Messier ...
July 13, 2023 A billowing pair of nearly symmetrical loops of dust and gas mark the death throes of an ancient red-giant star. The resulting structure, said to resemble an old style of English jug, is a rarely ...
Nov. 24, 2021 Mounded, luminous clouds of gas and dust glow in this Hubble image of a Herbig-Haro object known as HH 45. Herbig-Haro objects are a rarely seen type of nebula that occurs when hot gas ejected by a ...
Mar. 1, 2024 Up to a certain point, very luminous stars can have a positive effect on the formation of planets, but from that point on the radiation they emit can cause the material in protoplanetary discs to ...
Apr. 16, 2021 A survey of star formation activity in the Orion Nebula Cluster found similar mass distributions for newborn stars and dense gas cores, which may evolve into stars. Counterintuitively, this means ...
Jan. 12, 2023 Something is amiss in the Butterfly Nebula. When astronomers compared two exposures of this planetary nebula that had been taken by the Hubble Space Telescope in 2009 and 2020, they saw dramatic ...
Mar. 28, 2022 Helium-3, a rare isotope of helium gas, is leaking out of Earth's core, a new study reports. Because almost all helium-3 is from the Big Bang, the gas leak adds evidence that Earth formed inside ...
June 8, 2022 Astronomers have developed a new code to simulate the formation of a cluster of baby stars. Comparison with the well-known real case of the Orion Nebula shows that its off-center bubble of ionized ...
June 15, 2022 Astronomers have unveiled intricate details of the star-forming region 30 Doradus, also known as the Tarantula Nebula, using new observations from the Atacama Large Millimeter/submillimeter Array ...
Apr. 13, 2021 Researchers studied RCW 120 to analyze the effects of stellar feedback, and found that RCW 120 must be less than 150,000 years old, which is very young for such a ...
