7 new planets

NASA discovered 7 Earth sized planets or exoplanets that may have Alien life forms living there. ALL these new planets are orbiting a small Star. These newly found planets are much closer to Earth if compared to those found earlier. So these planets offer a big opportunity to finally find any extraterrestrial life outside our solar system. This is another giant discovery made my NASA . NASA published its findings about these planets on Wednesday during a news conference.

The newly found planets are residing in a solar system 40 light-years(i.e.-235 Trillion miles) from our planet Earth. For Astrophysicists this distance is not very much when compared to other planets outside our solar system. These newly discovered planets are orbiting a tiny dwarf star named Trappist-1. It has never been happened before that Astrophysicists found so many planets in this case 7 together that arr very much like Earth and are orbiting a common star.

Amaury H.M.J. Triaud, an astronomer at University of Cambridge stated that they might have made a very important step about finding alien life in the outer space. He added that if they managed to simulate same gaseous conditions that on Earth, they will know about alien life. These planets are revolving around a red tiny star which is not very hot and scientist are planning to find more planets by observing more Cool and red dwarf stars.

NASA plans to observe the type of molecules that are present in the atmosphere of those planets with the help of Hubble Space Telescope and other telescopes that are present on Earth. NASA is also launching James Webb Space Telescope next year which help in observing the wavelengths emitted by these planets.

Trappist-1 the dwarf star found is called so because it is named after an automated telescope in the Atacama Desert of Chile that the stargazers at first used to concentrate the star, is the thing that cosmologists call a “ultracool predominate,” with just a single twelfth the mass of the sun and a surface temperature of 4,150 degrees Fahrenheit, significantly cooler than the 10,000 degrees emanating from the sun. Trappist is a shortening of Transiting Planets and Planetesimals Small Telescope.

Sun vs Trappist-1
Trappist-1 is very much smaller and cooler than Sun. It is also a red star.

Amid the NASA news meeting, Dr. Gillon gave a basic relationship: If our sun were the measure of a b-ball, Trappist-1 would be a golf ball.

Until the most recent couple of years, researchers searching forever somewhere else in the system have concentrated on discovering Earth-estimate planets around sun-like stars. Be that as it may, it is difficult to select the light of a planet from the glare of a brilliant star. Little diminish diminutive people are considerably simpler to ponder.

A year ago, space experts reported the disclosure of an Earth-measure planet around Proxima Centauri, the nearest star at 4.24 light-years away. That revelation was made utilizing an alternate procedure that does not take into account investigation of the climate.

Trappist-1 intermittently darkened detectably, demonstrating that a planet may go before the star, blocking some portion of the light. From the state of the plunges, the space experts compute the extent of the planet.

Trappist-1’s light plunged such a large number of times that the space experts finished up, in research detailed a year ago, that there were no less than three planets around the star. Telescopes from around the globe then likewise watched Trappist-1, as did the Spitzer Space Telescope of NASA.

Spitzer watched Trappist-1 almost all day and all night for 20 days, catching 34 travels. Together with the ground perceptions, it let the researchers compute not three planets, but rather seven. The planets are too little and excessively near the star to be captured specifically.

 

All the seven planets found are orbiting very close to their dwarf star Trappist-1 that they are they are revolving much faster than any planet in our solar system. The innermost planet completes its one revolution around Trappist-1 in just 1.5 days and the planet which is farthest from Trappist-1 completes its revolution in just 20 days. It is being thought over that these planets were created farther from the dwarf star but were eventually pulled inwards by the gravitational force. For now lets hope for NASA finds out something interesting about alien lives on those planets.
