The glow of the Milky Way arcs across a sea of stars... and planets! 🌌
This panorama of the southern sky was created with 208 images from a year of observations by our Transiting Exoplanet Survey Satellite (TESS) mission. Swipe through the images to see TESS's discoveries: first, the host stars of 29 confirmed exoplanets (worlds beyond our solar system), and second, more than 1,000 candidate planets astronomers are now investigating.
To find exoplanets, the four TESS cameras capture a full sector of the sky every 30 minutes to search for transits. Transits occur when a planet passes in front of its host star from our perspective, briefly and regularly dimming its light.
