![]() ![]() Researchers further detailed the viability of LP-890-9’s two planets. Delrez explained that “a follow-up with ground-based telescopes” can help find what TESS misses due to its limited sensitivity to light in the near-infrared range, which is emitted by colder stars, including LP 890-9. “TESS searches for exoplanets using the transit method, by monitoring the brightness of thousands of stars simultaneously, looking for slight dimmings that might be caused by planets passing in front of their stars,” said lead report author Laetitia Delrez, a researcher at the University of Liège who contributed to the findings. NASA reveals wild plan to find underwater aliens on other planets The system’s outer planet is 40% larger than Earth and completes its orbit in about 8.5 days - placing it in a “habitable zone” relative to its star. That’s also what makes them so much harder to detect. ![]() Stars like these, including our Sun, are believed to be best for nurturing life on their orbiting planets - because the hotter they burn, the harder it is for life to survive. Its star, also called TOI-4306, or SPECULOOS-2, is the second coolest star known to host planets - behind TRAPPIST-1, which boasts seven Earth-sized planets. Their work is forthcoming in the journal Astronomy & Astrophysics, according to a university news release. “The habitable zone is a concept under which a planet with similar geological and atmospheric conditions as Earth, would have a surface temperature allowing water to remain liquid for billions of years,” said professor of Exoplanetology Amaury Triaud, whose SPECULOOS team recently confirmed the existence of LP 890-9c, as well as the habitability of its sister planet. Naturally, scientists turn to our own place in the solar system when searching for factors that contribute to life, such as the exoplanet’s size and distance from its host star, as well as that star’s size and temperature. ![]() The two exoplanets, LP 890-9b and LP 890-9c, were detected 100 light-years away, orbiting the star LP 890-9 - and have since been dubbed “super-Earths” for their similarities to our home planet, though somewhat more massive.īased on earlier findings by NASA’s Transiting Exoplanet Survey Satellite (TESS), researchers at the University of Birmingham in the UK used their SPECULOOS telescope - which stands for “Search for habitable Planets Eclipsing ULtra-cOOl Stars” - to confirm the habitability of these two planets.
