Newfound Alien World May Bridge Rare Gap in Planet Types

A student who obtained a master's degree in May cooperated with an international research team to find a special universe neighbors twice the size of the Earth.

Graduate student Merrin Peterson and a team of scientists in Canada, Germany and the USA studied Wolf 503b, 145 light years apart, using data from the NASA Kepler telescope.

Student Peterson of the University of Montreal 's Exoplanets Institute (iREx) said in a statement issued on September 6, world discovery took place very soon. After her and her consultant Björn Benneke began planning to find "interesting solar extranet planet candidate" based on Kepler's data recently announced in May 2018, a survey has occurred, she said Told. [Ten external planets that can receive extraterrestrial life]

According to the statement, it is orbit the old 'orange dwarf' orbit which is somewhat dimmer than the solar system external light, and it is very close once every 6th. According to university officials, the wolf 503b is very attractive as there is nothing to compare with our solar system. Its size makes the extrasolar planet the best position in science - wolves 503b are in areas that may be gases like rock "super earth" or "Neptune".

Kepler has studied the radius of thousands of outer planets scattered in the universe, but as researchers call it a phenomenon that is not fully understood in the Fulton space, so many outer planets are earth size. 5 or 2 times This is the result of additional observation of the wolf 503b - its radius is 03 times that of the earth - it is full of possibility of discovery

Generally, these Fulton gap planets observed by Kepler are difficult to study. According to the statement, they run around distant, dim star, making it difficult for researchers to calculate their density, measure the wavelength of light from them, and investigate their atmosphere.

Benneke of the University of Montreal said in a statement, "Wolf 503b is the only planet with a radius close to the gap, that star is bright enough to accept more detailed research."

According to Peterson, the closeness and brightness of the star helps support some tests, such as the wolf moves to measure the movement of the stars to determine the quality of the wolf 503b. Understanding quality will help scientists understand the composition of our celestial bodies. "If the composition of the Earth is similar to that of the Earth, within its radius, its mass must be 14 times its mass," a university official said. "Like Neptune, if that gas or volatile material contains a rich atmosphere, then it will be about half the weight."

As the Jame Webb Space Telescope flies, scientists can observe the presence of water and other chemicals in the atmosphere of Wolf 503b. The team said that characterizing the atmosphere of the wolf 503b would tell astronomers how other planets of Fulton gap size might look like.

"Wolf 503b provides an important opportunity to better understand the origins of this radius gap and the interesting population nature of" Super Earth "and" A-Neptune "as a whole. "The research authors write in their thesis

A paper detailing the results of the Peterson study was posted on the Journal of Astronomy on 30 August.

A newly discovered planet known as Kepler-186f was first discovered by NASA's Kepler Space Telescope and rotated around a dark red dwarf about 490 light years from the earth. Scientists say that the main star is darker than the Earth's sun and the planet is slightly larger than the Earth, but from the position and size of the universe world there may be water on the surface of Kepler-186f It suggests. You can learn more about the wonderful alien planet with the video created by Space.com. Tom Barkley, co-author of Kepler scientists and research on the new extrasolar planet, said, "One of the things we were looking for is one of the sun's star's livable areas, Space.com "This is an earth - sized planet and it is in a place where a cold star can live, so it is not the twin of the earth, but it may be the cousin of the earth. It has similar characteristics, but it is a different parent. "

Since the 1950's, the United States and other parts of the world have been fascinated by space exploration, extraterrestrial life, and extra-terrestrial planets, but in reality our own planet is an alien planet. To date, only 5% of our sea has been found and our sea accounts for 71% of the earth. Scientists believe that the sea already exists because the Earth is mere lava, and when it is formed quickly, all lives come from the ocean. So why did not we investigate it?
