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

On the Day of cosmonautics

April 12 (cosmonautics Day) is one of the outstanding dates in the history of the world. It is in this auspicious day super booster successfully launched into orbit the first ever space ship “Vostok-1” with the first cosmonaut, a citizen of the Soviet Union, Yuri Gagarin.

“Man is ever weary of the country in which he lived, and tried his best to push. The desire for the Unknown, to the knowledge of what was outside of his native place — the home, the field, the planet has always been one of his most powerful feelings”.

Cosmonautics day — a memorable date, celebrated on April 12, installed to commemorate the first manned flight into space, it is a celebration of the human mind, of intelligence.

Unknown to the mankind was Space. But in 1957 changed everything. “The beginning of the Space age marked by the launch on 4 October 1957 the first Soviet artificial satellite of the Earth. News of the launch of the satellite inscribed in Golden letters in history”.

“The space age… With these words, the majority of the inhabitants of the Earth are related some concrete representation”. Meanwhile, the history of Space exploration is to our eyes. Continue reading

What do you think, will it be possible flights to other stars?
Most likely will be possible. No. When flying on supersonic aircraft the pilot is experiencing a huge overload and must be in good health and keep fit. For flights into…

Comets fascinate the human mind since ancient people first noticed the white tail streaking through the night starry sky. We remember the date when the comet flies past the Earth…
