NASA's TESS Unveils 6,000 Exoplanets in 96-Slice Sky Map
6 articles · Updated · NewsBytes · May 21
NASA on May 21 released TESS's most detailed night-sky map yet, showing about 6,000 potential and confirmed exoplanets after years of observations since 2018.
The survey identifies those worlds by measuring tiny dips in starlight when planets cross in front of their stars, a method applied across 96 slices of the sky.
About 700 planets in the map are confirmed, while thousands remain candidates; NASA said some lie in habitable zones, while others appear volcanic or are being consumed by their stars.
TESS data this year also pointed to a super-Earth system with an unusual companion and possible evidence of two planets colliding, underscoring the mission's broader scientific reach.
Beyond exoplanets, the satellite is helping track young-star streams, asteroid activity and galactic behavior, with NASA saying the archive still holds more discoveries.

TESS and the Exoplanet Boom: How NASA’s Survey Satellite Unlocked Over 10,000 New Worlds and Transformed Planetary Science
Overview
NASA's Transiting Exoplanet Survey Satellite (TESS) is transforming exoplanet discovery by systematically surveying the entire sky with its four cameras, capturing images every 30 minutes. This approach steadily fills in more of the night sky, allowing TESS to identify new, nearby planetary systems and build an extensive dataset. The data is a treasure trove for exoplanet hunters and also provides valuable insights into other astronomical phenomena, such as young star formations and asteroid monitoring. Importantly, TESS data is freely available, supporting open science and enabling researchers worldwide to make new discoveries.
