The Transiting Exoplanet Survey Satellite (TESS), has discovered 66 new planets. The confirmation of the discovery of the following 2100 or so planets is yet as the scientists are still working on it.
The tiny drops in heaven in the brightness of the stars that reveal the planets is scan by the spacecraft, but we can’t see them now.
The primary mission of the TESS has been formally complete after two years. Still, TESS has a long life left not like many other NASA tools.
An extended mission will be initiated which will result in giving many more amazing discoveries, as NASA said. The southern skies (new planet and astronomical events) will be searched when the spacecraft returns for scanning.
TESS is NASA’s most powerful tool which is used for spotting exoplanets. Till now, TESS has already discovered roughly about seventy-five percent of the sky as seen from Earth. This is done in large chunks, examining the brightness of the stars over the period of months.
TESS uses a very simple technique to spot the Exoplanets.
The satellite keeps an eye on the stars for an extended period of time and observes when the brightness decreases at regular intervals. The dip in the brightness of the stars is a hint that something ( or many things) are revolving occasionally or regularly around the stars, blocking its light. This is as simple as it sounds.
Earlier, TESS completes its mapping in the southern sky, and after completing that it starts mapping the northern sky until it’s primary mission gets complete. NASA informed that once again TESS will map the southern sky in the search of some new discoveries.
The TESS team introduced some new improvements in its system by which the satellite collects and processes its data. Every ten minutes, it’s the camera will capture new images.
