Astronomers discovered another exoplanet within the habitable zone. It is true that there is a nuance.
Ross 508b orbits the red dwarf Ross 508 at 37 light-years away from Earth. This planet orbits the red dwarf Ross 508 at a distance of 37 light-years from Earth. It allows water to exist on its surface in a liquid form, which is the most important component of life.
Ross 508b is four times the mass of Earth. It is a rocky planet. This means it is part of the super-Earths class. The transit method was not used in this case, but a new infrared monitoring technology was used to discover the exoplanet. The new InfraRed Doppler instrument, which was just installed on the telescope, and the Hawaiian Subaru telescope were used to accomplish this. This is the first infrared spectrograph of high precision for telescopes 8 meters-class.
Scientists will also find Ross 508b very interesting, since it is the third exoplanet to be discovered around such small stars. Ross 508 is eight times more mass than the Sun.
To return to the nuance, Ross 508b does not always enter the habitable zone. Instead, he visits it once every 11 days. However, this does not necessarily mean there is no water in a liquid form. This is an important nuance.
The most important nuance is that Ross 508 (a red dwarf) is much more active than the Sun. Red dwarfs have more flares than the solar ones, so these flares are stronger. Red dwarfs, which are very close to their habitable zones, are also small, rather cold stars. Red dwarfs’ habitable zones are therefore likely to be continuously bombarded with radiation. However, there are many nuances that can allow life to develop and continue for a long period of time.
