In a groundbreaking discovery, astronomers have identified TOI-1846 b, a super-Earth exoplanet located 154 light-years away.

“HD 20794 d is not a second home for humanity, but its position and peculiar orbit give us a unique opportunity to study how the conditions for habitability vary over time and how these ...

Earth" that is located about 154 light-years away and is nearly twice as big and four times as massive as our planet.

最后，对生物学家来说，“宜居星球”必须满足现代生命所需的物理化学条件。这些基本条件需要通过研究地球生命生存的极限条件来确定，这意味着存在液态水（但并不局限于地表水，也可以是地下海洋，如上文所述）、适宜的温度（介于0~110℃）及能量源。能量可以是光能 ...

Astronomers have found a new exoplanet named TOI-1846 b. This planet is nearly twice the size of Earth. It may contain a lot ...

与此同时，今年早些时候，研究人员在太阳系外发现了另一颗“超级地球”。据牛津大学的研究结果，这颗被命名为HD 20794 d的系外行星质量是地球的六倍，其表面可能存在液态水。它距离地球20光年，在一颗类似太阳的恒星的宜居带内运行。

这颗新发现的行星被命名为HD 20794 d，质量是地球的6倍，距离地球约20光年，围绕一颗类似太阳的恒星运行。 它的轨道位于该星系的宜居带内，这意味着它与恒星的距离合适，其表面能维持液态水存在，液态水是生命所需的一种关键成分。

Scientists have discovered a water-rich "super-Earth" named TOI-1846 b, which is twice the size and over four times the mass of Earth.

A decades-old pursuit to explore for life beyond Earth has received new impetus with a recent discovery that promises to simplify and make routine the task of searching for life on distant planets ...
