Scientists have discovered almost 100 new "exoplanets" in the search for Earth-like planets that could support life. At present, the NASA's K2 mission had discovered more than 100 new planets adding to the list of 200 other planets that were discovered over its course of discovery. An worldwide team led by Andrew Mayo from the National Space Institute at the Technical University of Denmark took a closer look at 275 exoplanet candidates, validating 149 of them.
"We found that a portion of the signs were caused by numerous star frameworks or commotion from the rocket", ponder lead creator Andrew Mayo, a Ph.D. understudy at the Technical University of Denmark's National Space Institute, said in an announcement.
'We found that some of the signals were caused by multiple star systems or noise from the spacecraft. The planets range from rocky, Earth-like planets to massive gas planets like Jupiter. Four years after launch in 2013, Kepler was hit was a mechanical snag that crippled the telescope. In this stage of Kepler's life, the space observatory periodically shifts its field of view to prevent radiation from the sun interfering with its balance.
Exoplanet explorers want to find other Earth-sized planets that may be capable of supporting life. It records the light levels of hundreds of thousands of stars in search of characteristic light fluctuations that occur when exoplanets cross in front of their host stars.
It is given a closer look before it is confirmed to be an exoplanet - but the task is not an easy one as scientists must differentiate between signals from a candidate and signals from other spacecraft.
The first planet orbiting a star similar to our own sun was detected in 1995.

In a private Instagram group chat , Cruz talked about killing Mexicans, keeping black people in chains and cutting their necks. No police reports were immediately available for those calls so it was not possible to determine whether Cruz was involved.
For a long time, the rocket gazed consistently at around 150,000 stars, searching for little dunks in their shine caused by the entry of planets over their countenances.
That planet around HD 212657 circles its star in just 10 days.
"Planets around brilliant stars are vital in light of the fact that space experts can take in a considerable measure about them from ground-based observatories". "As more planets are discovered, astronomers will develop a much better picture of the nature of exoplanets which in turn will allow us to place our own solar system into a galactic context", Mayo said.
"Exoplanets are a very exciting field of space science".
"The follow up K2 mission, on the other hand, has provided us with a great deal of interesting individual planets and systems that we can now start to study in greater detail". A team of five members at Ball Aerospace, Colorado attempted to revive the spacecraft with an unique solution of using sunlight pressure to obtain a stabilized course for which, the commands were fed onto the system and then transmitted to the Kepler spacecraft in a desperate attempt to revive it before finally bidding goodbye if it doesn't work. An exoplanet refers to a planet which orbits a star outside the solar system.
Astronomers may be able to even glean information about its atmosphere, as they have done for TRAPPIST-1 planets.
