15 New Exoplanets Near Cool Dwarf Stars Have Been Discovered And One Of Them Can Hold Life

The orbital observatory Kepler discovered 15 new exoplanets near cool dwarf stars. One of them is particularly interesting since the scientists confirmed it’s having an Earth-like atmosphere and could also possess oceans, thus, it can hold life.

The study involved the examination of images and readings done by Kepler

Teruyuki Hirano from the Tokyo Institute of Technology’s Department of Earth and Planetary Sciences and his colleagues analyzed the data collected by Kepler in the first three years after it was repaired by the NASA engineers.

As scientists noted, they were interested in celestial bodies revolving around stars that are not like our Sun and red dwarfs, which are small and dull stars with a bigger lifespan. However, Kepler was originally intended to search for planets from brighter and larger stars than our Sun, which complicated the search for the red dwarfs.

“It’s important to note that the number of planets around red dwarfs is much smaller than the number around solar-type stars. Red dwarf systems, especially coolest red dwarfs, are just beginning to be investigated, so they are very exciting targets for future exoplanet research,” said Hirano.

Over the past two years, astronomers have discovered several star systems and exoplanets, such as Proxima B and the seven small planets revolving the around the TRAPPIST-1 star.

Scientists found 15 new exoplanets near cool dwarf stars

In total, the Japanese scientists managed to find 15 new exoplanets that are revolving around the cool dwarf stars. Many systems were formed by planets similar to Venus but one system was particularly interesting for the scientists – K2-155.

The newly discovered K2-155 system is located in the constellation Taurus and is at about 200 light-years away from us. It is the home to three planets, the farthest of which, K2-155d, looks habitable and, according to the scientists, is similar in its climate and hydrological conditions to the Earth.

According to Hirano, it will be possible that, when NASA will launch the TESS telescope, scientists will be able to get the first accurate data on the composition and temperatures of these new 15 exoplanets near cool dwarf stars.planets.
