A world that bears more than a passing similarity to Earth has just been discovered orbiting a star just 40 light-years from the Solar System.
What we don't yet know is whether Gliese-12b has an atmosphere. That's the factor that could make a huge difference to whether the world is hospitable to life like Earth, or This is what we have with Gliese-12b. It was found in data from the TESS exoplanet-hunting telescope, and Dholakia, his co-lead author Larissa Palethorpe of the University of Edinburgh and University College London, and their team followed up with a number of different telescopes to confirm that the TESS detecting was legit.
Whether or not the exoplanet has an atmosphere could play a huge role in what the surface conditions are like, though. Gliese-12b gets about 85 percent of the radiation received by Venus – but Venus is covered in a thick, choking atmosphere that generates a greenhouse effect, resulting in an
