新的观测显示,一个年轻的无赖行星,距离620光年之遥,正在以创纪录的速度消耗气体和尘埃而迅速增长。 A young rogue planet, 620 light-years away, is growing rapidly by consuming gas and dust at a record pace, new observations show.

天文学家已经探测到一个年轻的无赖行星,Cha 1107-7626号,离地球约620光年之遥,在2025年8月的激增期间,消耗天然气和尘埃的速度创下纪录,每秒60亿吨,比以前所见速度快八倍。 Astronomers have detected a young rogue planet, Cha 1107-7626, about 620 light-years away, consuming gas and dust at a record rate of six billion tons per second—eight times faster than previously seen—during a surge in August 2025. 地球是木星质量的五到十倍,有一到两百万年的历史,它仍在通过类似恒星形成的过程而成长,很可能得到强磁场的帮助。 The planet, five to ten times Jupiter’s mass and one to two million years old, is still growing through a process resembling star formation, likely aided by strong magnetic fields. 在非常大型望远镜和詹姆斯·韦伯空间望远镜观察下,它的活动挑战了一种概念,即无赖行星是无活动行星,在自由漂浮的世界中暴露出动态的、类似于恒星的行为。 Observed with the Very Large Telescope and James Webb Space Telescope, its activity challenges the notion that rogue planets are inactive, revealing dynamic, star-like behavior in a free-floating world.
