Nasa spacecraft spots gaseous planet 23 times the size of Earth
‘Super-Earth’ among trio of planets and six supernovae detected by Tess mission
Three new planets and six supernovae outside our solar system have been observed by Nasa’s planet-hunting Tess mission in its first three months.
Since it started surveying the sky in July, the MIT-led Transiting Exoplanet Survey Satellite project has identified Pi Mensae b, a “super-Earth” that travels around its star every six days, and LHS 3844b, a rocky world with an orbit of only 11 hours.
