TESS

NASA's TESS telescope has already notched up a few noteworthy achievements. Its latest feat, however, is also its most significant, with the space telescope having now identified its first Earth-sized exoplanet in the habitable zone.

While NASA's TESS satellite was staring off into the depths of interstellar space, the comet 46P/Wirtanen wandered into view. The satellite managed to catch an explosive outburst from the comet in more detail than ever seen before.

NASA has released an enormous mosaic of the southern sky, stitched together from images captured by the agency’s Transiting Exoplanet Survey Satellite (TESS) over the course of its first year of science observations.

The Breakthrough Listen has announced that scientists from NASA's Transiting Exoplanet Survey Satellite (TESS) mission will be working alongside its own researchers as they ramp up the search for intelligent, extraterrestrial life.

NASA's Transiting Exoplanet Survey Satellite (TESS) has observed a gigantic black hole ripping apart a star in a distant galaxy.

NASA’s TESS mission has been very busy lately, making many exoplanet discoveries. Now, the productive little satellite has made another important discovery – the closest super-Earth that’s potentially habitable.

NASA's TESS probe is halfway through its two-year primary mission and has completed its survey of the southern sky in its search for extrasolar planets. According to the space agency, the unmanned telescope has discovered 21 confirmed exoplanets and 850 candidates for further study.

NASA’s Transiting Exoplanet Survey Satellite was built to search for new planets, but astronomers at Ohio State found it could also observe supernovas created by exploding white dwarf stars. This means we might soon have a better idea about why they explode, and what they leave behind.

Three new, roughly Earth-sized exoplanets have been found orbiting a nearby star. Named L 98-59b, c and d, the small worlds were spotted by NASA’s TESS, as part of a larger haul of data that finally brings the total tally past the milestone of 4,000 exoplanets discovered to date.

Another 18 exoplanets have been added to the haul, but the difference this time is that all of them are roughly Earth-sized – much smaller than the Neptune-sized average found so far. The discovery was made in old data, using a new and more sensitive algorithm.

A team of astronomers led by MIT has confirmed that NASA's unmanned Transiting Exoplanet Survey Satellite (TESS)​ space telescope has discovered its first Earth-sized exoplanet. Called HD 21749c, it orbits the main-sequence star HD 21749, 52 light years away from Earth.

A new exoplanet hunting tool​ has been installed onto an Australian telescope. Dubbed Veloce, the instrument looks out for the wobble of a star caused by the gravitational tug of orbiting planets, and it specializes in red dwarfs, the most common type of star in the universe.
