詹姆斯·韦布太空望远镜发现了位于双鱼座、距地球154光年的超级地球HD 3167 b拥有大气的强有力证据1。这一发现由芝加哥大学科学家Brandon Park Coy领导的研究团队做出，相关成果已发表在《天体物理学杂志通讯》上1。
HD 3167 b每24小时绕其宿主星一圈，表面极其炎热1。该行星是迄今发现的最冷的拥有大气的熔岩行星1。目前已有五颗拥有大气的陆地行星被发现，其中四颗处于超热状态1。
HD 3167 b的发现有助于科学家理解岩石行星如何保留大气，同时为认识年轻地球可能曾经的样子提供了参考1。该研究项目正在对10个超热熔岩行星进行观察1。
The James Webb Space Telescope has found compelling evidence that HD 3167 b, a super-Earth located 154 light-years away in the constellation Pisces, possesses an atmosphere 1. The exoplanet completes one full orbit around its host star every 24 hours and features an extremely hot surface, making it the coolest known lava planet with a confirmed atmosphere to date 1.
This discovery advances scientific understanding of how rocky planets retain their atmospheres and provides insights into what the young Earth may have resembled 1. The research was led by Brandon Park Coy, a scientist at the University of Chicago, and has been published in The Astrophysical Journal Letters 1. Among the five known terrestrial planets with atmospheres, four are ultrahot; HD 3167 b stands as an exception to this trend 1. The research initiative is currently monitoring ten ultrahot lava planets as part of a broader investigation into atmospheric retention on such extreme worlds 1.
