Astronomers have spotted an intriguing "super-Earth" orbiting its red dwarf star inside the habitable zone, meaning it could likely host liquid water on its surface, a key factor for the potential habitability of exoplanets.
At just 1.55 times the Earth's radius, it's fairly small for a planet of its type. But what really caught the researchers' attention was its suspected sibling, which they believe is even smaller and also roughly the size of our own planet, lurking within the same region.
If confirmed, the latter "would represent the smallest habitable zone planet" discovered by NASA's Transiting Exoplanet Survey Satellite (TESS), per a paper about the finding published in the journal Monthly Notices of the Royal Astronomical Society.
