NASA 55 Cancri e a planet where the temperature exceeds 2500 degrees

Earth really seems to be an unusual planet as those referenced in the universe does not have the same conditions. It would therefore be impossible to live on 55 Cancri e, because the temperature is extremely high. Two times larger than Earth, 55 Cancri e-gravitates to "only" 1.5 million kilometers from its star, Earth really seems to be an unusual planet as those referenced in the universe does not have the same conditions. It would therefore be impossible to live on 55 Cancri e, because the temperature is extremely high.

Two times larger than Earth, 55 Cancri e-gravitates to "only" 1.5 million kilometers from its star, a distance 100 times less than that between the Earth and the sun. Therefore a year there lasts only 18 hours, but mostly it's a bit hot, 1,400 degrees between night and day 2,700 degrees. In addition, the proximity and the laws of gravity are only one side of the planet is constantly exposed to the sun and still he does there night on the other side.

This excessive temperature is not really surprising when one focuses on the composition of this planet. In fact, 55 Cancri e has the distinction of being covered with larva, so this explains the 2,500 degrees that make it completely inhospitable to humans. While some fans were able to observe a stealth explosion on Jupiter, scientists from NASA focus on 55 Cancri e that displays a size two times greater than that of Earth. Now it is possible to obtain various information through the Spitzer telescope has had the opportunity to capture it in all directions.
One side of this planet where it is only 1100 degrees

Other features away the similarities between these two planets as 55 Cancri e is very close to its star and to make a turn, she puts only 18 hours. The astronomers also observed that the temperature on one side was around 2500 degrees, but, on the other, the situation is totally different. Indeed, studies show it is twice as hot as the thermometer climbs up to 1100 degrees only. To find it, you have to go in the constellation of Cancer at 40 light years from the Blue Marble. Some 55 Cancri e could well be compared to the hell seen referenced conditions. Meanwhile, scientists are trying to unravel the mystery about these differences from one face to another. Several hypotheses are stated as the proximity to its star or the lack of atmosphere, and even radiation.

Observe 55 Cancri e with the James Webb telescope

Experts and evoke a thermal shock which would be responsible for the molten rock. Two faces are seen, since we have one side of the lava solidified while on the other it is more rivers of lava that are identified. The universe still has some gray areas that Men do not have the chance to experience. However, with the arrival of the James Webb telescope will be much more efficient than the Spitzer or the famous Hubble, the situation could change. From 2018, other more accurate data could therefore be relayed to 55 Cancri e. This planet is fascinating and shows how Earth is exceptional.

A new path in the study of exoplanets

55 Cancri e still keeps many secrets, including the origin of its extreme heat, according to astronomers, can not be explained by the presence of the star. However, recent findings open a new avenue in the study of exoplanets. This is indeed the first time that reaches such conclusions for such a small planet.

"This is the first weather map we have to a world of super-Earth guy, so it's only interesting in terms of success," said to Mashable, the astronomer Sarah Ballard. But from 2018, scientists might be able to go even further with the arrival of the James Webb Space Telescope NASA supposed successor to Hubble Space Telescope. With a mirror of 6.5 meters, is expected to revolutionize the study of exoplanets, offering more precise observations and especially allowing astronomers to see further. A promising prospect in finding a planet similar to ours and potential traces of life in the Universe.

Less than a year after its restoration the Kepler telescope discovered over 100 exoplanets!

While Kleper telescope is in poor condition, he still continues his explorations and even discovered 100 exoplanets in just one year. Three of which are larger than Earth. NASA made the announcement as it remains a feat for a telescope sent outside our solar system. Indeed, most of these devices, even sophisticated, discovers a dozen exoplanets during shipment.

Redesigned, the giant eye, measuring nearly a meter in diameter and is equipped with a sensor of 95 million pixels, observed objects he had not detected before. It has, for example, discovered several exoplanets in one solar system and the stars that orbit the hottest items and more luminous than our sun. The Kepler telescope never ceases to surprise the scientific community because it multiplies exploits. Now he can add to his resume the explosion of a star as it was captured for the first time. The result is truly spectacular.

With today's technology, scientists have the opportunity to achieve the unthinkable. The Kepler telescope back on the front of the stage with good news as it filmed a supernova. This is the first time such a phenomenon is the subject of a catch, this discovery will likely be part of the history of astronomy forever. They are astronomers from NASA that are responsible for the dissemination of the news, they can also collect a massive amount of information. The universe still has some gray areas in particular on the end of a star.
