Why Just the ninth planet in the Solar system, according to the International astronomical Union (IAU), there are eight planets. Pluto the IAU decision in 2006 is no longer considered a planet by going to the class of dwarf planets because it is not dominant in its space orbit. According to scientists, the Solar system may be over two thousand dwarf planets. However, the definition of a planet as a dwarf is still a matter of controversy. In particular, a crucial role may play the size of a celestial body.

Therefore, to say that discovered ninth planet in the Solar system very early.”

The scientist reminded that beyond the orbit of distant planets in the Solar system has many objects that are studied by astronomers. Among them was discovered a new heavenly body, which claims the title of planet in the Solar system.

According to the authors, it is a gas giant with a mass of 5-10 times the mass of the Earth. This planet supposedly moves in an elliptical orbit, making a complete revolution around the Sun for 10-20 thousand years. According to the calculations of astronomers to confirm the planet’s existence by observation through the telescope, will take several years. Continue reading

Gravity puzzle, or how space ships can cover vast distances in the Universe

It turns out that people have learned to make interstellar travel over huge distances. Previously it was thought that use gravity for space jump can only sverhrazdutoe of civilization, as fuel is always limited — it is impossible to bring as much as you want. However, science has leaped forward. Not everyone knows about what happened is a real space revolution.

This principle, the flights with the help of gravity, demonstrated in the sensational film “interstellar”. Read more about this amazing phenomenon tells Kip Thorne, a theoretical physicist, consultant to the film (he invented everything that has to do with science) and the author of the book “interstellar. The science behind the scenes” .

The view from the ship, performing a gravitational slingshot

Though Director Christopher Nolan decided not to show the gravitational slingshot (maneuvers, which we describe below) in “interstellar” Kip Thorne was curious, as if they saw Cooper, the main character, piloting the “Ranger” to the planet Miller. So he is using his equations, modeled images for a camera that would Record with the Ranger, making the maneuver around the black hole before landing on planet Miller. Continue reading

Discovered the largest known planets

The biggest of all open still planets astronomers found in the constellation of Hercules.

Space body, named TrES-4, is drawn around the star GSC02620-00648, remote from the Earth at a distance of 1435 light-years. A new extrasolar planet about 70% larger size than Jupiter, but has a much smaller mass, which indicates its extremely low density. In addition, the object is deleted only 7 million kilometers from its star, making its surface extremely hot, over 1300 degrees Celsius.

Around its star turns the planet every 3.55 days, you one earth week to two years, listed on TrES-4. Because of the relatively weak gravity TrES-4, probably permanently loses a part of the upper layer of its atmosphere, which stretches behind the planet in the form of a curved tail resembling a comet.

“This is the largest of all known exoplanets, says lead researcher George Mandushev from the Lowell Observatory. It is so large that using existing scientific models to superhot giant planets its size is quite difficult to describe. Continue reading
