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

Space tourism

Focus on the future characteristic of all mankind. The progressive development of society necessarily reflected in tourism. So, the era of space exploration marked the beginning of space tourism. Mankind began to think about the possibilities of travelling to distant stars. In 2001 Russia launched the first space tourist – the American citizen Denis Tito. Space tour cost him $20 million Space tourism is still very expensive form of tourism. But the growing interest in space travel is forcing tour operators to develop tours of the space, work for the future.

Russia launched the first space tourist – the American citizen Denis Tito. Space tour cost him $20 million.

Japanese Association of Aeronautics established a study group on problems of development of space tourism. The session was attended by over 40 representatives of scientific organizations. The Japanese have developed the concept of tourist rockets reusable, which is able to take a 3-hour space flights with 45-50 tourists on Board. Average tourist flight will cost $25 thousand Is equivalent to the cost of round-the-world journey on sea cruise liner. Continue reading
