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

Новый телескоп NASA TESS открыл свою первую экзопланету

The strip of stars and galaxies consist of the enormous and Minute Magellanic Clouds, two dwarf galaxies orbiting the Milky Skill, and a few brilliant stars that saturated the digicam's detectors: Beta Gruis and R Doradus."This dawn science image exhibits the capabilities of TESS' cameras, and exhibits that the mission will imprint its fabulous attainable in our watch one other Earth", acknowledged Paul Hertz, astrophysics division director at NASA, Washington.A image of all sectors might possibly well maybe be considered below. The detailed image was produced using all four of the spacecraft's wide-field cameras for 30 minutes, while the portion above shows the view captured by a single detector of one of its cameras. The frame is part of a swath of the southern sky TESS captured in its "first light" science image as part of its initial round of data collection.

NASA's Paul Hertz, astrophysics division director, said: "In a sea of stars brimming with new worlds, TESS is casting a wide net and will haul in a bounty of promising planets for further study,". The black lines in the image are gaps between the camera detectors. In contrast, TESS will survey about 85 percent of the night sky, targeting stars that are 30 to 300 light-years away. Transits are the phenomenon of a planet passing in front of its star when viewed from the satellite direction, and this causes a dip in the brightness of the star. During its first year of operations, the satellite will study the 13 sectors making up the southern sky. Thirteen sectors in the southern celestial hemisphere will be covered first, followed a year later by 13 sectors in the northern hemisphere. Download TESS "first light" images in HD resolution.

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


TESS has been built upon the legacy of Kepler spacecraft of NASA, as it also utilizes the transits to find out exoplanets. It was launched in April but took some time to actually work for the science objectives.

The stars which become its targets are in fact 30 to 300 light years away and nearly 30 to 100 times brighter when compared to Kepler's targets which too are 300 to 3,000 light years away. Come what might possibly, scientists will be ready to burn up TESS's discoveries with flooring-based mostly observatories and the long-delayed James Webb Space Telescope to expose us extra regarding the composition of these a ways away planets.
