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

In two years, tourists will fly into space on a balloon

Those who have always dreamed to visit space and go on an unforgettable journey that may be just once in your life, now have the opportunity to experience a new miracle of technology: a high tech space balloon .

The Spanish company plans within the next two years to offer services in transportation of passengers over long distances, which will significantly reduce flight time.

Space balloon ?bloon? – the idea of the entrepreneur Jose Mariano Lopez-Urdiales. the head of the company Zero2Infinity from Barcelona.

During the flight passengers will have the opportunity to observe the fantastic scenery of our planet. will experience weightlessness and will be able to eat, if you wish. Space tourists will travel along the edge of the Earth’s atmosphere in a special capsule, which seats 6 people – 4 passengers and 2 pilots .

The developers of the new vehicle say that the flight will be very quiet and smooth, and the passengers will have the unique opportunity to see the sun and the stars simultaneously. it is impossible to observe, being on the surface of the Earth. Continue reading

Comet

Comets are Solar system bodies having the form of vague objects, usually with pale clot kernel in the center and tail. They are among the most beautiful celestial bodies. hazy Bright shell surrounding a core of hazy, long tail, extending sometimes to half the sky, fast motion among the stars – all this makes comet different from other heavenly bodies. The comet can be observed when a small ice body, called the nucleus of the comet is approaching the Sun at a distance that is less than 4-5.e. warmed by the sun, and it begins to stand out gases and dust that are visible as a result of their illumination by the Sun.

Gases and dust released from the nucleus, creating around him a hazy shell – atmosphere of the comet, components along with the core of the head of the comet. The atmosphere of a comet continuously dissipates in interplanetary space: under the action of radiation pressure and interaction with the solar wind gases and dust are carried away in the direction from the Sun forming the comet’s tail.

Most of the comets in the middle of the head there is a bright star-like “core”, representing the illumination of the Central, most dense zone of true gases around the comet’s nucleus. Continue reading
