Astronomers have detected elusive pulsation patterns in dozens of young, rapidly rotating stars thanks to data from NASA’s Transiting Exoplanet Survey Satellite (TESS). The discovery…
Through the noise, a class of stars reveals its inner workings; poor ‘social distancing’ identified using NASA space telescope. By listening to the beating hearts…
In a generic brick building on the northwestern edge of NASA’s Goddard Space Flight Center campus in Greenbelt, Maryland, thousands of computers packed in racks…
A star that pulses on just one side has been predicted in theory. But it took two simultaneous discoveries on opposite sides of our planet…
Astronomers announced Monday (January 6, 2020) the first discovery made by NASA’s TESS mission of a two-star planetary system. Led by researchers at NASA’s Goddard…
NASA’s Transiting Exoplanet Survey Satellite (TESS) has discovered its first Earth-size planet in its star’s habitable zone, the range of distances where conditions may be…
Using data from NASA’s Transiting Exoplanet Survey Satellite (TESS), astronomers at the University of Maryland (UMD), in College Park, Maryland, have captured a clear start-to-finish…
When NASA’s James Webb Space Telescope launches in 2021, one of its most anticipated contributions to astronomy will be the study of exoplanets—planets orbiting distant…
The glow of the Milky Way — our galaxy seen edgewise — arcs across a sea of stars in a new mosaic of the southern…
For the first time, NASA’s planet-hunting Transiting Exoplanet Survey Satellite (TESS) watched a black hole tear apart a star in a cataclysmic phenomenon called a…
A new study using data from NASA’s Spitzer Space Telescope provides a rare glimpse of conditions on the surface of a rocky planet orbiting a…
A piping hot planet discovered by NASA’s Transiting Exoplanet Survey Satellite (TESS) has pointed the way to additional worlds orbiting the same star, one of…
NASA’s newest planet hunter, the Transiting Exoplanet Survey Satellite (TESS), has discovered three new worlds — one slightly larger than Earth and two of a…
NASA’s Transiting Exoplanet Survey Satellite (TESS) has discovered 21 planets outside our solar system and captured data on other interesting events occurring in the southern…
