➀ Astronomers have detected the lowest-mass dark object ever found in the universe, a mysterious object with a mass of roughly one million times that of our Sun, located approximately 10 billion light-years from Earth.

➁ The discovery challenges the widely-accepted Cold Dark Matter (CDM) theory, which predicts that dark matter forms clumps or halos across a vast range of sizes.

➂ The object's true nature remains unknown, with two leading possibilities: a clump of dark matter or a very compact, inactive dwarf galaxy.

➀ NASA的Webb望远镜成功捕捉到附近星系中多颗行星的图像，展示了其分析系外行星大气化学成分的能力。

➁ NASA确认詹姆斯·韦伯太空望远镜（JWST）已捕捉到地球银河系附近多个系外行星的直接图像。

➂ 通过对HR 8799行星系统的观测，Webb望远镜收集了强有力的证据，表明该系统中的四颗气态巨行星的形成方式与木星和土星相似，它们通过缓慢构建固体核心最终从原行星盘吸收气体。
