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. 10, 2022 — A supernova is a stellar explosion, which occurs when the lives of some really massive stars come to an end. In this violent epilogue, the star expels the material from its outer layers by means of a ...
Apr. 14, 2022 — The MAGIC telescopes have observed the nova RS Ophiuchi shining brightly in gamma rays at extremely high energy. The Gamma rays emanate from protons that are accelerated to very high energies in the ...
Apr. 14, 2022 — Astronomers have found a slimmer type of red giant star for the first time. These stars have undergone dramatic weight loss, possibly due to a greedy companion. The discovery is an important step ...
July 22, 2021 — Any life identified on planets orbiting white dwarf stars almost certainly evolved after the star's death, says a new study that reveals the consequences of the intense and furious stellar winds ...
