Planets of the Solar system

Jupiter thousands of years ago named after the king of Roman gods, and reigns among the nine planets of our Solar system, rivaling the Sun in its splendor. The largest planet is located far beyond the main asteroid belt. The mass of Jupiter exceeds the mass of all other planets combined.

Jupiter is the largest planet in the Solar system. The semimajor axis of Jupiter’s orbit is 5.2.e. the eccentricity of the orbit e = 0,0489, the period orbits – 11,867 years. The inclination of the orbital plane to the plane of the Ecliptic is 1°1817″. The average speed along the orbit – about 13.1 km/s.

The period of rotation around the axis is 9 hours and 55 minutes. Each dot on the equator moves at a speed of 45 thousand miles per hour. Due to the centrifugal force of Jupiter is noticeably flattened (compression rate greater than 6 %). Since Jupiter is not a solid ball, and consists of gas and liquid, the Equatorial parts rotate faster than the polar regions. The rotation axis of Jupiter is nearly perpendicular to its orbit, therefore, the planet has no seasons.

The mass of the planet is M = 318 M = 1,9∙10 27 kg, radius R = 11,2 R = 71 492 km, However, Jupiter is very thin: its density is 1.33 g/cm 3. which is four times less than the density of the Earth. The acceleration of gravity at the level of the cloud surface of Jupiter sostavljaet = 2,53 g. Continue reading

According to the data sent to earth orbiting space telescope GALEX, astronomers have made the image of the Veil nebula in the ultraviolet range. The Veil nebula (W78, Sharpless 103), which is also known as the Loop nebula or nebula Fishing net, is a diffuse nebula in the constellation of Cygnus. Was opened on 5 September 1784 by astronomer William Herschel. Previously, astronomers believed that this huge and relatively faint supernova remnant that exploded about 5,000 to 8,000 years ago, is at a distance of about 2500 light years from Earth, however, studies that fulfilled the space telescope “Hubble”, showed that the nebula is much closer – at a distance of 1470 light years. However, it extends for a distance of about 90 light-years, taking in the sky region of 3 degrees. Astronomers have smashed the nebula into four parts: separation – nebula “witch’s broom” (NGC 6960). South-West side of the Pickering’s Triangle (NGC 6979), East side (NGC 6992), which represents the fibrous structure of the nebula and the North side (NGC 6995).

Astronomers have discovered in the nearby galaxy M95 supernova. The discovery was made on March 16, 2014, when astronomers, both professionals and Amateurs, noted a bright spot on the outskirts of a spiral galaxy with a jumper M95 (NGC 3351), which is at a distance of 38 million light-years away in the constellation of Leo.

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
