An unprecedented collection of pulsating giant red stars has been identified by astronomers at the University of Â鶹´«Ã½<\/span> at M\u0101noa Institute for Astronomy<\/a> (IfA<\/abbr>). Using observations from NASA\u2019s<\/abbr> Transiting Exoplanet Survey Satellite (TESS<\/abbr>), the researchers detected the stars, whose rhythms arise from internal sound waves and provide the opening chords of a symphonic exploration of our galactic neighborhood.<\/p>\n

Since its launch in 2018, TESS<\/abbr> has primarily hunted for exoplanets\u2013worlds beyond our solar system. But its sensitive measurements of changing stellar brightness make the telescope ideal for observing stellar oscillations or material within the internal structure of stars. It\u2019s an area of research called asteroseismology.<\/p>\n
