Red Giants

This visualization shows the new sample of oscillating red giant stars (colored dots) discovered by the Transiting Exoplanet Survey Satellite (TESS). The colors map to each 24-by-96-degree swath of the sky observed during the primary mission. The view then changes to show the positions of these stars within our galaxy, based on distances determined by the Gaia mission. The scale shows distances in kiloparsecs, each equal to 3,260 light-years, and extends nearly 20,000 light-years from the Sun.
