研究萨迦 A* 附近三团异常气体云的天文学家表示,它们几乎相同的轨道很可能有共同起源,新观测将其追溯到一个大质量接触双星系统。

芝加哥大学学生团队利用斯隆数字巡天数据,在银河系中识别出一颗极低金属丰度的红巨星,研究人员认为它很可能起源于银河系之外。

借助欧洲空间局 Gaia 数据和一种新的探测算法,天文学家在银河系周围识别出数十个微弱的恒星流候选体,显著扩展了对古老引力残骸的绘图范围。

New research suggests the Sun and thousands of similar stars may have made a dramatic journey from the galaxy's dense inner regions to the quieter outer disk billions of years ago—a migration that may have made life on Earth possible.
Astronomers using the ALMA telescope have produced the largest image ever taken of the Milky Way's central region, spanning 650 light-years. The mosaic reveals a complex network of cold gas filaments and dozens of molecules, from simple silicon compounds to complex organics like acetone and ethanol.
An international team of astronomers has detected what could be an ultra-fast pulsar lurking near the supermassive black hole Sagittarius A* at the center of our galaxy. If confirmed, this discovery would provide an unprecedented natural laboratory for testing Einstein's general relativity in extreme gravitational conditions.
Columbia University scientists working with the Breakthrough Listen project have identified a millisecond pulsar candidate spinning at 8.19 milliseconds near Sagittarius A*. If confirmed, the discovery could provide a powerful new tool for testing Einstein's general relativity under extreme gravitational conditions.
