It contains an ocean in 20 degrees Celsius and years lasting 25 days
One of the residues of astronomy is to find planets with conditions similar to those we have in TiraEssential case for There may be life in it.
There are many external planets (i.e. outside our solar system) that offer some promising properties. One of the people who look at the best is LHS 1140 B.
Discover for the first time in 2017, LHS 1140b is 41 light -year -old It can be the best opportunity for humanity to find liquid water in a world outside our solar system.
Last year, after being carefully noticed by James Web telescope for spaceScientists were able to discover more about this world very far, but at the same time very cool.
Thus, it contains an ocean with a possible temperature for some 20 ° C. It is believed that it is significantly rocky and largely greater than the earth. It has a planetary block of 5.6 lands and a year that lasts only 25 days, according to NASA.
LHS 1140 B has a nitrogen atmosphere, although more notes are needed to confirm it completely. “The discovery of an atmosphere similar to the Earth on a moderate planet carries the capacity of the web to the limit; it is possible; We just need a lot of note time. Rene Duyon, from the International Research and Stock Exchange Council (IREX) last year.
“The current signal for a rich nitrogen atmosphere requires more data. We need at least one year of notes to confirm that LHS 1140b has an atmosphere, and perhaps Two or three others to detect carbon dioxideAdd doyon.
When the telescope data was sent to the ground, it was “the first time that scientists saw an indication of an atmosphere in A planet outside the rocky planets or ice is rich in a living areaAccording to Ryan McDonald, a member of NASA Sagan in the Department of Astronomy at the University of Michigan, which helped analyze the LHS 1140b atmosphere.
Telescope data also indicates that the external planets mass can consist of 10 and 20 % liquid water. While this may mean that the planet seems to be a large snowball, the side that looks towards the sun can have a warm liquid circumference, giving it the appearance of the eyeball.
Charles Kadio, a doctorate at the University of Montreal and the main author of an article on the discovery, says: “Of all the moderate external planets currently known, LHS 1140 B can be the best bet for one day indirectly on the presence of liquid water on the surface of a foreign world. An important milestone in searching for external planets It is possible that it is valid for housing. “
