Scientists Discover 45 New Exoplanets


In what seems to be a big discovery in the number of exo-planet confirmations for the past few years, scientists have discovered a trove of new exo-planets in solar systems that are beyond our own solar system. The new discovery has dwarfed the number of planets reported as discovered by the extra solar surveys.

The new discovery will help the scientists to improve the existing models of the solar system while also enabling them to further investigate the atmosphere in the exoplanets. Scientists have used some new techniques to validate the findings of the new planets and this could further accelerate confirmation of more new planets.

Astronomers were able to confirm the new findings and explain further details about them by pooling data from NASA’s Kepler and European Space Agency’s Gaia telescopes. The new findings yield some of the most surprising characters of the exoplanets. For example, four of the newly discovered planets take less than 24 hours to orbit their host stars. That is to say that a year on these four planets is actually shorter than a day on Earth.

Scientists believe that this phenomenon reflects that there could be more of such short period planets than were thought earlier. Sixteen of the new exoplanets are believed to be same of the size as Earth and one planet, in particular, is extremely small – about the size of Venus. Further, this planet was close to the limit of what can be possibly detected by the scientists.

Scientists have always hoped to study the kind of planets and their atmosphere present in the space but were not able to draw valid conclusions as there were not enough number of planets to provide a solid statistical analysis. The new discovery will enable them to further their study by offering a new theoretical understanding of the formation of solar system.

Further, the new planets provide good targets to carry on detailed individual studies of the planets to know the measurements of their planetary composition, their atmosphere and the interior structure. Especially, there are about 18 planets in different multi-planet systems which could be analysed better to study their atmosphere which will in turn help in teaching us how our own planet was formed. However, we’re still to remain on Earth.
