Just in 50 light-years from the Earth, there are around 1,560 stars, likely orbited by thousands of planets. These extrasolar planets—also known as exoplanets—might be rocky and have an arrangement similar to that of Earth. Some of them can even harbor life. About 99% of these alien worlds are unexplored—but this can change soon. By using NASA’s novel TESS (transiting exoplanet survey satellite), the whole sky search is being conducted for possibly habitable planets nearby our solar system. TESS—which orbits Earth every 13.7 Days—and ground-based telescopes are balanced to discover hundreds of planets in the coming few years.
This can change astronomers’ perceptive of alien worlds and can offer targets to screen with latest-generation telescopes for marks of life. In just a year, TESS has spotted over 1,200 planetary entities, 29 of which scientists have already verified as planets. Considering TESS’ exceptional capability to concurrently investigate tens of thousands of stars for planets, the operation is anticipated to yield more than 10,000 new worlds. These are exhilarating times for astronomers and, in particular, for those searching for exoplanets. TESS mission by NASA was launched in April 2018 to search for other mostly Earth-sized planets, but with an unusual technique. TESS is searching for unique dimming incidents that occur when planets pass in the presence of their host stars, obstructing some starlight. These transit incidents reveal not only the existence of the planets but also their orbits and sizes.
Recently, NASA was in news as its chief stated, “Pluto is a planet” as it is a complex and amazing world. The long-term debate about Pluto’s planethood lately received a public boost up from Jim Bridenstine—NASA Administrator—who stated that the world should certainly be a planet. The observations from the space agency’s mission—New Horizons spacecraft—in 2015 disclosed that Pluto was extremely complex than anticipated, with a possible underground ocean, unrefined materials (the latent precursors of life) on the surface and a multi-layered atmosphere, Bridenstine asserted during the IAC (International Astronautical Congress) 2019, Washington.
