This illustration depicts a planet partially hidden in the glare of its host star and a nearby companion star. After examining a number of binary stars, astronomers have concluded that Earth-sized planets in many two-star systems might be going unnoticed by transit searches, which look for changes in the light […]

Artist’s impression of the surface of Gliese 486b.

Also, using a combination of different observing techniques […]

The newly discovered TOI 451 planetary system features three planets orbiting the same sun. Credit: NASA’s Goddard Space Flight Center   ENLARGE A newly discovered planetary system will provide researchers with the rare chance to study a group of growing planets, according to research co-led by Dartmouth. The new system, named […]

An artist’s rendering of five planets orbiting TOI-1233, four of which were discovered using the Transiting Exoplanet Satellite Survey (TESS), an MIT-led NASA mission. Credit: NASA/JPL-Caltech MIT-led NASA mission finds a multi-planetary system that could be an “ideal laboratory” to study planetary formation and evolution. MIT researchers have discovered four new exoplanets […]

ANIMATION Using data from facilities including NASA’s Neil Gehrels Swift Observatory and Transiting Exoplanet Survey Satellite (TESS), scientists have studied 20 instances and counting of regular outbursts of an event called ASASSN-14ko. Astronomers classify galaxies with unusually bright and variable centers as active galaxies. These objects can produce much more energy […]

TOI 700, a planetary system 100 light-years away in the constellation Dorado, is home to TOI 700 d, the first Earth-size habitable-zone planet discovered by NASA’s Transiting Exoplanet Survey Satellite. Credit: NASA’s Goddard Space Flight Center TESS, the Transiting Exoplanet Survey Satellite, was launched in 2018 with the goal of […]

This artist’s impression shows LTT 9779b near the star it orbits and highlights the planet’s ultra-hot (2000 Kelvin) day-side and its quite toasty night-side (around 1000 K).

Illustration of NASA’s Transiting Exoplanet Survey Satellite (TESS) at work. Credit: NASA’s Goddard Space Flight Center On July 4, NASA’s Transiting Exoplanet Survey Satellite (TESS) finished its primary mission, imaging about 75% of the starry sky as part of a two-year-long survey. In capturing this giant mosaic, TESS has found 66 […]
