They find 104 planets outside the Solar System in three months

If not record, hit the post: in just three months, different astronomers announced the discovery of & # 39; more than one hundred exoplanets (the so-called planets revolving around stars off the Sun) thanks to the combination a & # 39; terrestrial and space telescopes. The precise figure is & # 39; 104; They are very different and are expected to play an important role in research on life in the Universe.

It was a very devoted and active search for exoplanets in & # 39; in recent years. One of the pillars that made it possible is the success of the Kepler Space Telescope, which was launched in 2009 to ifittexhom, and worked like this: if a planet crosses (transits) in front of its star, the observed brightness of the star falls & # 39; small amount Kepler discovered several exoplanets using this method. However, such regulatory phenomena are not only caused by exoplanets, thus confirming that the phenomena are really caused by them is very important.

meteoric career

F & # 39; these months, the astronomers from around the world are competing to confirm whether or not x exoplanets & # 39; it is the data suggest Kepler is winning.

An international team & # 39; researchers from the University & # 39; Tokyo and the Center for Astrobioloń°ija National Institutes of Natural Sciences of Japan investigated 227 candidates for exoplanets using other telescopes, both space and terrestrial, according to National Astronomy Observatory Japan (NAOJ). .

Were those who confirmed that 104 of them are really exoplanets, and also discovered that seven have orbital periods ultra-short & # 39; less than 24 hours. As the process & # 39; & # 39 formation; this type of & # 39; planets remains unclear. Additional study & # 39; these celestial bodies helps to advance in the investigation of the processes involved in their formation, is reported in & # 39; statement.

They were also able to confirm many of exoplanets & # 39; low rock mass, slightly less than the size of Earth, as well as some planetary systems with & # 39; over exoplanets.

The successor

The student at the University & # 39; Tokyo and the main author of the documents describing the findings, John Livingston, He explained that although Kepler Space Telescope from NASA officially removed, his successor, called TESS, has already begun collecting data.

"Only in the first month & # 39; its operations, TESS has found many new exoplanets and will continue to discover many more. We can expect numerous exciting discoveries in the coming years", says Livingston.
