Transiting Exoplanet Survey Satellite (TESS) launched by NASA by Falcon 9 rocket to search for exoplanets i.e., planets outside the solar system having the capability to look at 200,000 stars at around 300 light years distance from the Earth.
NASA announced that TESS has sent the first picture of Milky way skyspace that shows countless stars possible of having Solar System like model similar to Sun (star) keeping hold of eight planets. The picture was taken actually when TESS is approaching to the outer elliptical orbit around the Earth and it claims it to be just 0.25 percent of the sky it was intended to capture.
After reaching the defined path, TESS monitors the stars and planets revolving around them would periodically block the vision of satellite and the satellite's function is to monitor the differences in brightness for a certain period. With the data collected, the scientists could be able to locate the positions and characteristics of the planets. This is termed as transiting method. The reading shall be taken in June as stated by NASA. Following TESS, the James Webb Telescope also is under development stage much useful for future missions.
TESS is following the function of Kepler that has identified 3,700 exoplanets and still it is expected that there would be 4500 unidentified planets among which 50 exoplanets were anticipated to have Earth-like living conditions suitable for human living.
