Astronomers detect more than 100 exoplanets New

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 Astrobioloń°iku 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The spacecraft was withdrawn in its current orbit and secure, & # 39; away from Earth, according to NASA.
