Astronomers surprised us again with a new discovery something that looks like Earth. It is also possible to be glacial, but the possibility to be habitable is existed, too!
How it would be if the newest discovery of a 31 light-years distance from our solar system, would be true? Astronomers come with the latest information of their discovery stating that the ‘super-Earth’, also named GJ 357 d, is actually larger than Earth, almost by six times, orbiting a dwarf sun, littler than ours, each 55,7 days. What’s more intriguing is the fact that astronomers tend to strongly believe that this planet could offer conditions of existing just like Earth does.
GJ 357 d it’s believed to have a dense atmosphere, maintaining the water on its area like our planet, and we could have the possibility to catch some signs of life with a telescope that will be available.
NASA’s TESS (Transiting Exoplanet Survey Satellite) first found another planet, called GJ 357 b,a, but it was as they stated just a ‘hot Earth’, orbiting a dwarf sun. GJ 357 d, however, obtains the most chances to be a habitable area, with temperatures not so hot nor cold. Lisa Kaltenegger, the director of Carl Sagan Institute at Cornell and a professor in astronomy, announced that telescopes will begin their mission in 2021 and 2025, of exploring the planet to see if it will have oceans or if it’ll be rocky.
Kaltenegger expressed her feelings towards the perfect target of these telescopes, due to the fact that the distance will be very close and the brightness huge. She also stated that they can gather enough information about that light and study it next to find out if the chemical structure of the atmosphere or if there are any water and oxygen.
