August 18, 2021. Red Giants Across The Sky
Astronomers have identified an unprecedented all-sky collection of pulsating red giant stars.
The find, made with data from NASA's Tess and ESA's Gaia missions, confirms our fundamental prediction in galactic astronomy:
In an animation, different colored fields cover sections of Earth.
As the Earth breaks apart, the colors turn into a spray of pixels. Text, Younger, higher-mass stars lie closer to the bright plane of the Milky Way, rather than the diffuse outskirts.
At the center of concentric circles.
The stars' pulsations, created by internal sound waves, tell scientists accurate details about the stars' size and internal structure.

TESS's broad coverage allow scientists to make these measurements across almost the entire sky.
