Hubble discovers a planet that presses on the speed of a record



With the help of the NASA Hubble telescope, a team of astronomers at the University of Johns Hopkins in Baltimore, Maryland, has discovered a long, medium planet – from dimensions like Neptune – they have called GJ 3470b. and it evaporates a hundred years faster than another similar celestial body that was discovered from the front, the GJ 436b, according to an article published on Thursday at the Phys.org scientific portal.

"Here is the test The planets can lose a significant part of their total mass. The GJ 3470b loses more growth than any other planet we have seen so far, "said David Sing, a distinguished teacher in this American university and the project director who led the discovery." In a few billion years, half of the planet, "Sing added.

The recent discovery, which will allow the scientific community to understand better how planets are developed and evolved, will be part of the PanCET Exoplanet Comparative Treasury program, and # 39; n aim to measure 20 exoplanets with ultraviolet, optical and infrared light. as they orbit their stars, "am decide how each planet is affected by itselfenvironment"

The new planet, which is 96 light years of Earth and surrounds a red red star in the direction of Cancer contrast, has significantly lost more mass than GJ 436b and she has an extremely low exosffer because it is less density and receives a burst of stronger radiation from its host star. The lower density of the GJ 3470b means that it can not seriously persist in the hot atmosphere.

Although the star that is home to the similar planet already studied between 4,000 and 8,000 million years old, the star that is home to the new heavenly body is only 2 billion years old, which means that the planet's atmosphere gets more radiation to heat, because being younger is more active.

According to the study led by Sing, the GJ 3470b could has lost up to 35% of total mass. Also, scientists believe that in a few billion years it could be a simple rocky foundation as a result of losing all your gas. The researcher hopes that his team can study more exoplanets that look for helium in infrared light, which would allow more search range than if they used hydrogen in ultraviolet light , collects Can.
