The newest discovery by the astronomers says that there are around 20 other planets that have a similar atmosphere like the Earth’s, which further implies certain planets could be the source of alien life or life in general.
The discovery was achieved with the help of the impressive Kepler space telescope which claims the cosmos owns orbit stars very much matching the Sun.
Jeff Coughlin, who was the leader of the Kepler project, stated that there was a particular, outstanding exoplanet which had an orbit of 395 Earth days so as a comparable dimension, while another had an orbit of only 18 days.
The planet which is similar to Earth is around 97% of Earth’s size and has similar climate conditions to our tundra areas.
Even though the climate was quite wintry, it still was mild enough to sustain water in as a liquid substance. And we all know water is the main element to maintain life, not just human but supposed alien life too.
Mr. Coughlin told New Scientist: “If you had to choose one to send a spacecraft to, it’s not a bad option.”
The planet, so-called KOI-7923.01, has colder climate conditions which are a result of the larger distance from its star, which is also colder than the Earth’s star or simply, the Sun.
This means its weather conditions are comparable to the Earth’s tundra regions, for instance, Siberia; however, these areas would still be capable of providing life.
Kepler project’s team, however, cautiously suggested that in order to draw conclusions they need to make further investigation.
Moreover, this discovery will be a fragment of a bigger picture. New research is coming up from the Hubble Space Telescope related to this subject and containing the previously achieved results.
Scientists working on Kepler have also found the “Rosetta Stone” which shows that apparently, our own solar cycles are not alone in the galaxy.
Researchers analyzed the star HD 173701 and concluded it is almost equal to our Sun, in terms of size, mass and age.
One of the writers of a theme in the Astrophysical Journal, Travis Metcalfe, reported to Forbes: “This star is a Rosetta Stone for stellar dynamos – despite having the same mass and age as the sun, its cycle period is 7.4 years instead of 11.”
Christoffer Karoff, the paper’s principal author and an astronomer at Denmark’s Aarhus University, said: “We show that the chemical composition of a sun-like star can influence the dynamo generated in the star.”
Earlier this year, the Kepler probe found 219 new exoplanets but only 10 of them were possibly habitable.
According to NASA’s Research Centre, there are about 4,034 latent planets in our solar system worth of observing.
