NASA's TESS released its most complete all-sky mosaic, using images from April 2018 to September 2025.
The mosaic shows 679 confirmed and 5,165 candidate exoplanets, assembled from 96 sectors over eight years.
Rebekah Hounsell said TESS found planets from Mercury-size to larger than Jupiter, including some in habitable zones.
Allison Youngblood said TESS also maps young-star rivers, tracks galactic dynamics, detects near-Earth asteroids, and shows the Magellanic Clouds about 160,000–200,000 light-years away.
