Following the "first light" imagery release, NASA's astrophysics division director Paul Hertz 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". Still, it is not really the first time that TESS sent an image back to Earth.
TESS has been built upon the legacy of Kepler spacecraft of NASA, as it also utilizes the transits to find out exoplanets.
Launched in April this year, TESS began science operations in July and captured the released imagery in early August. "This first light science image shows the capabilities of TESS' cameras, and shows that the mission will realise its incredible potential in our search for another Earth", Hertz said. During its first year of operations, the satellite will study the 13 sectors making up the southern sky.
The probe's exemplary inaugural science image is the first look at TESS's unique approach to planet hunting.
There are parts of a dozen constellations in the TESS image, according to NASA, along with a globular cluster that includes hundreds of thousands of stars. NASA had previously shared a two-second test exposure image of space that TESS had taken with just one camera during its testing phase.
The fresh pictures utilise all Four of the satellite's large-self-discipline cameras, providing a panoramic look of the southern sky stitched collectively from sixteen determined pictures.
As well as the large and small Magellanic Clouds, the galaxies closest to ours, in addition to the stars, Beta Gruis and R Doradus, reported the National Aeronautics and Space Administration (NASA). NASA's James Webb Space Telescope and a new generation of ground-based telescopes will be well-suited for the follow-up work. The results represent "first light" for the new space telescope, and indicate that it is ready to begin looking for exoplanets by monitoring nearly the entire night sky to look for regular dips in the brightness of relatively nearby stars. The image is absolutely packed with stars, taking a half hour to soak in the light and produce the collection of pictures you see below. 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 will scan a much larger region of the sky than Kepler did - and one that is closer to Earth. TESS will study 13 sectors in the southern sky the first year, followed by 13 sectors in the northern sky the second year.
Tess is 5 feet (1.5 meters) wide and is shorter than most adults.
