NASA’s TESS Shares First Science Image in Hunt to Find New Worlds

TESS's scientific mission is largely the same as Kepler's - to take images of exoplanets.

The first official image can be considered Large and the Small Magellanic Cloud, striking Beta in the constellation of the Crane and the red giant R Golden fish.

TESS is equipped with four cameras that allow it to cover 85% of the sky. This new image, however, uses all four of the satellites wide-field cameras and it consists of a panoramic view of the southern sky made by stitching together 16 different images. "This first research the shows features cameras TESS", - said the Director of the Department of astrophysics at the headquarters of NASA in Washington, Paul Hertz.

TESS could discover thousands of new planets relatively close to Earth.

'This first light science image shows the capabilities of TESS's cameras, and shows that the mission will realize its incredible potential in our search for another Earth'.

The Transiting Exoplanet Survey Satellite (TESS) snapped a photo using its four wide-field cameras on August 7, almost four months after it blasted off from Cape Canaveral. The images include parts of a dozen constellations, from Capricornus to Pictor, and both the Large and Small Magellanic Clouds, the galaxies nearest to our own. NASA had previously shared a two-second test exposure image of space that TESS had taken with just one camera during its testing phase.

TESS will spend two years monitoring of the 26 sectors of the sky for 27 days each. If we're going to search out lifestyles within the cosmos, or no longer it's a lawful advice to study varied planets.

The first year of operations will have TESS studying 13 sectors of the southern sky. NASA's James Webb Space Telescope and a new generation of ground-based telescopes will be well-suited for the follow-up work. When the data is analyzed, scientists will be able to detect minute dips in a star's brightness - suggesting that a planet has passed in front of it (relative to the telescope, of course). TESS is picking up the exoplanet-hunting mantle from Kepler and is targeting stars much brighter than Kepler investigated. It was launched back in April, but it took some time to get the satellite up to speed and begin working on actual science objectives. But while Kepler focused on small fields of view for long periods of time, TESS adopts a wider, more comprehensive view.

Tess is 5 feet (1.5 meters) wide and is shorter than most adults.
