天文学家发现了一个新的迅速形成的星球 它对行星形成的现有理论提出了挑战 Astronomers discover a new, rapidly formed planet that challenges existing theories on planetary formation.

天文学家发现了一个新的行星, 名为IRAS 04125+2902 b 或 TIDYE-1b, 形成仅300万年, 时间是地球所花的一半。 Astronomers have found a new planet, named IRAS 04125+2902 b or TIDYE-1b, that formed in just 3 million years, half the time it took Earth. 距离地球520光年远,这个行星的轨道更接近其恒星,比水星更接近太阳,其直径比地球的直径大11倍。 Located 520 light-years away, this planet orbits closer to its star than Mercury does to the Sun and has a diameter 11 times larger than Earth's. 它的发现 通过观测恒星光亮度的下降 向目前关于行星形成速度的理论提出了挑战 Its discovery, made by observing dips in the star's brightness, challenges current theories on how quickly planets can form.
