The NASA TESS probe has been in space for nearly a year, and it is definitely using powerful imaging tools. As we saw in NASA's first snapshot from last year, TESS is able to study large parts of the sky in great detail, and this work has paid off on a large scale.
TESS stands for Transiting Exoplanet Survey Satellite recognizes exoplanets by detecting changes in the brightness of the stars of these planets. In a new article, researchers explain how the study of stars led to TESS's presumably first large-scale discovery of exoplanets.
The scientists who originally discovered the object, known as TOI 197.01 (TOI means "TESS object" of interest ") originally studied a phenomenon known as the" starquake ". These are seismic waves that roll over stars and cause a shift in their brightness.
Instead of finding a starquake, the team discovered the telltale signs of planetary motion between the Earth and the host star. By scrutinizing the changes in the star's light that shine around the planet, researchers have managed to narrow down their possible composition.
TESS collects an immense amount of data that researchers can scour, and missions like this tend to make further discoveries for months or even years after the spacecraft's work is completed. The initial mission duration of TESS has been estimated to be only two years, but it is likely to be extended if the satellite demonstrates its ability to operate at a high level.
