An international team of astronomers, using a combination of ground-based and space telescopes, discovered more than 100 extrasolar planets (exoplanets) in just three months – rotating around stars outside the sun.
These planets are very diverse and are expected to play an important role in the development of exoplanets and life research in the universe.
Researchers at the University of Tokyo and the research team at the Center for Astrobiology of the National Academy of Natural Sciences surveyed 227 departments based on data from the second mission of the NASA Kepler Space Telescope (K2 mission) and the use of other space telescopes and foundations. Exoplanet candidate. telescope.
They confirmed that 104 of them were really exoplanets. The confirmed ultra-short orbital period of the seven exoplanets is less than 24 hours.
The formation of exoplanets with such short orbital periods remains unclear.
The team also identified many low-mass rock exoplanets that are less than twice as massive as Earth and some planetary systems with multiple exoplanets.
The study is detailed in the Journal of Astronomy.
The research team said the results of the study brought K2 production to more than 360 planets, and by inferring, we expect K2 to find 600 planets before the end of 2018 is expected to deplete its onboard fuel.
In October, NASA decided to retire its Kepler Space Telescope, which has been working deep in space for nine years. Kepler discovered planets from outside the solar system, many of which may be promising places of life.
According to NASA, the spacecraft is retired in the current safe orbit, away from the Earth.
