NASA’s Transiting Exoplanet Survey Satellite has discovered a new super-earth exo-planet named GJ 357 d.
“This is exciting, as this is humanity’s first nearby super-Earth that could harbour life — uncovered with help from TESS, our small, mighty mission with a huge reach”
- This is the first potentially habitable world ever discovered. Super-earth is located about 31 light-years from our location in the universe.
- Transiting Exoplanet Survey Satellite aka TESS is a mission designed to look for exoplanets throughout the viewable universe.
- The massive exoplanet has a dense atmosphere which means it could retain liquid water on its surface, much like planet Earth.
- NASA will be able to confirm the existence of life on the planet after their next telescope, James Webb Space Telescope goes online.
- The ‘Super-earth’ revolves around M-type dwarf sun, GJ 357. This sun harbours three planets. One of these planets – GJ 357 d – aka Super Earth, is in the Goldilocks zone.
- The evidence of planetary existence in the system came in February last year when the dwarf sun could be seen dimming about every 3.9 days.
- The other planets – GJ 357 b, GJ 357 c – are incredibly hot. GJ 357 d, on the other hand, could possibly support life.
- Is it a possibility that we will travel to exoplanets anytime soon? Probably not. We do have a chance to see humans travelling to Mars though.
