Stunned Scientists Discover SUPER EARTH Planet Close to Earth, That Could May Reveal Existence of Aliens
This type of orbit means any water on the planet would freeze and melt depending on where it is in its orbit Irish Sun, Millie Turner, Science Reporter 28 Jan 2025 ![]() SCIENTISTS have discovered a new super-Earth with an eccentric orbit that swings it in-and-out of its stars habitable zone. Nearby exoplanet, HD 20794 d, orbits a star very similar to our Sun - a placement that is necessary for life as we know it. Located roughly 19.7 light-years away, the exoplanet is a relatively close neighbour of Earth. An international team of experts from the University of Geneva (UNIGE) and the Swiss research foundation NCCR PlanetS found the exoplanet after analysing nearly two decades worth of data. They used a new system called YARARA, an algorithm recently developed at UNIGE that can go through data like a fine-tooth comb. ![]() We analysed the data for years, carefully eliminating sources of contamination, said Michael Cretignier, co-author of the study and developer of YARARA during his PhD at UNIGE. The exoplanets closeness to Earth makes it easier to study, as its light signals are stronger and unobscured by cosmic noise. Xavier Dumusque, senior lecturer and astronomy researcher at the UNIGE, said: HD 20794, around which HD 20794 d orbits, is not an ordinary star. Its luminosity and proximity makes it an ideal candidate for future telescopes whose mission will be to observe the atmospheres of exoplanets directly. ![]() Researchers are already eyeing up the European Southern Observatorys Extremely Large Telescope, which is under construction in the Chilean Atacama Desert. https://www.youtube.com/watch?v=-cuvlIDI7UE |
