Astronomers – scientists who study stars, moons, planets and galaxies – at the National Aeronautics and Space Administration (Nasa) in America recently announced the discovery of four new exoplanets in space.
Exoplanets specifically orbit around other stars, while all the planets in our solar system orbit around the sun. The discovery of these exoplanets is part of Nasa’s Transiting Exoplanet Survey Satellite – or Tess – mission which is focused on searching for new planets orbiting the brightest stars in Earth’s sky.
The young exoplanets are orbiting stars named Tess Object of Interest ( TOI) 2076 and TOI 1807 and are more than 130 light years away from Earth. A light year is the distance light travels in 365 days. Since 2018 the Tess telescope has been watching for changes in the sky’s light which is caused by stars.
