科学家发现了一个名为HD 20794 D的“超级地球”系外行星,只有20光年。它的尺寸为六倍,它在可能存在液态水的可居住区中绕着阳光般的恒星旋转。这种紧密的接近度使其成为未来太空任务的主要候选人,以研究其气氛和潜在的生活迹象。 但是,地球的怪异轨道意味着它的水会冻结或定期融化,从而使人们对生命的迹象进行复杂化。然而,它的独特特征帮助科学家提炼行星宜居模型。 HD 20794 D的近端的强光信号使使用未来望远镜的研究变得更加容易,从而有可能揭示其大气和表面条件的更多信息。虽然生活的存在仍然未知,但在宜居区的附近系外行星的发现引起了科学家之间的兴奋。

Despite over 7,000 exoplanets being discovered, the search for extraterrestrial life continues.

But now, a nearby "super Earth", located about 20 light years away could be that home to extraterrestrial beings, according a new report from the NY Post, citing Astronomy & Astrophysics

Dr. Michael Cretignier, scientist with Oxford University, commented: “I’m now very enthusiastic to hear what other scientists can tell us about this newly discovered planet.”

“Excitingly, its proximity with us – only 20 light-years – means there is hope for future space missions to obtain an image of it," he continued.

UK researchers confirmed the “super-Earth” and an international team analyzed two decades of precise data from Chile’s HARPS and ESPRESSO spectrographs, verifying the object as an exoplanet.

Scientists are intrigued by HD 20794 d - it is six times Earth's size and it orbits in a habitable zone where liquid water could exist. It circles a sun-like G-star in 647 days, slightly less than Mars’ orbit.

“It is among the closest Earth analogues we know about and given its peculiar orbit,” Cretignier added. 

The NY Post report said that HD 20794 d follows an eccentric orbit, drifting in and out of the habitable zone, causing any water to freeze or melt depending on its position. This unique trait helps scientists refine models of planetary habitability.

At just 19.7 light-years away, its proximity makes it easier to study, with strong light signals ideal for future telescopes analyzing exoplanet atmospheres.

Despite its location in the habitable zone, whether it can support life remains uncertain. Scientists still need to determine if it has an atmosphere or surface water.
