An international team & # 39; astronomers discovered more than 100 extrasolar planet (exoplanets) – revolving around stars off the Sun – in only three months, using & # 39; combination & # 39; based telescopes on earth and space.
These planets are quite different and is expected to play a big role in the development of the research field of exoplanets and life in the Universe.
The team involved researchers at the University & # 39; Tokyo and the Astrobioloġiku Center National Natural Sciences Institutes investigated 227 exoplanet candidates based on data from the second mission of the Kepler Space Telescope (K2 mission) NASA, as well as use of & # 39; Other space telescopes and ground-based telescopes.
They confirmed that 104 of them are really exoplanets. Seven of confirmed exoplanets have orbital periods ultra-short & # 39; less than 24 hours.
The process & # 39; & # 39 formation; b exoplanets & # 39; such short orbital periods yet clear.
The team also confirmed many of rocky exoplanets & # 39; & # 39 with low mass, mass less than twice that of Earth and planetary systems with a & # 39; over exoplanets.
The study is detailed in the Journal Astronomy.
The findings bring the production of & # 39; K2 for more than 360 planet, and b & # 39; extrapolation, we expect that K2 has discovered 600 planet before the expected reduction of fuel on board at the end of 2018, said team.
F & # 39; October, the American space agency NASA decided to withdraw its Kepler Space telescope worked in deep space for nine & # 39; years. Kepler planets discovered outside the solar system, many of which could be promising venues for life.
The spacecraft was withdrawn in its current orbit and secure, & # 39; away from Earth, according to NASA.
