July 6, 2021 —Using sophisticated simulations of the whole of the Local Group of galaxies, including the Milky Way, the Andromeda galaxy and their respective satellite galaxies, researchers have shown that the ...
Feb. 8, 2023 —Astronomers have uncovered striking new evidence for a mass migration of stars into the Andromeda Galaxy. Intricate patterns in the motions of stars reveal an immigration history very similar to that ...
Aug. 27, 2020 —In a landmark study, scientists using NASA's Hubble Space Telescope have mapped the immense halo of gas enveloping the Andromeda galaxy, our nearest large galactic ...
May 25, 2021 —A new map of dark matter in the local universe reveals several previously undiscovered filamentary structures connecting galaxies. The map, developed using machine learning, could enable studies ...
Jan. 11, 2023 —Scientists have reported something unexpected about the distinct populations of stars that make up the Triangulum galaxy: In this satellite galaxy, a close companion of the much larger Andromeda ...
Oct. 25, 2022 —VLA observations revealed that cosmic rays can play an important role in driving winds that rob galaxies of the gas needed to form new stars. This mechanism may be an important factor in galactic ...
July 28, 2021 —科学家发表了一个新的详细的无线电image of the Andromeda galaxy -- the Milky Way's sister galaxy -- which will allow them to identify and study the regions of Andromeda where new ...
July 21, 2021 —Astronomers have made detailed observations of a large tidal flow around the Sombrero galaxy, whose strange morphology has still not been definitively ...
Nov. 23, 2022 —Pioneering a new technique, researchers have peered into the extremely faint light that exists between galaxies to describe the history and state of orphan ...
Feb. 26, 2021 —A study has found the most densely populated galaxy cluster in formation in the primitive universe. The researchers predict that this structure, which is at a distance of 12.5 billion light years ...
