10 most amazing space objects
№10. R136a1 - the most massive star of
R136a1 is at a distance of 165 000 light-years from Earth in the Tarantula Nebula in the Large Magellanic Cloud. This blue hypergiants is the most massive star ever known to science. Also, the star is also one of the brightest, the light emitting up to 10 million times greater than the sun.
Star weight of 265 suns and the mass of the formation - more than 320.
R136a1 found a team of astronomers from the University of Sheffield led by Paul Crowther 21 June 2010.
Still it remains unclear origin of such supermassive stars: they formed with the weight initially, or they are formed of several smaller stars.

№9. Boomerang Nebula - the coolest place in the universe
Boomerang Nebula is located in the constellation Centaurus at a distance of 5000 light years from Earth. nebula temperature is -272 ° C, which makes it known to the coldest spot in the universe.
The gas flow coming from the central star Boomerang Nebula, moves with a velocity 164 km / s, and constantly expanding. Because of such high-speed expansion of the nebula in such a low temperature. Boomerang Nebula colder than even the relic radiation from the Big Bang.
Keith Taylor and Mike Skarrot object named "Boomerang Nebula" in 1980 after observing it with the Anglo-Australian Telescope at Siding Spring Observatory. Sensitivity only device allowed to fix a small asymmetry in fractions nebula appear from the assumption that the curved like a boomerang shape.
Boomerang Nebula was photographed in detail space telescope "Hubble" in 1998, after which it became clear that the nebula has a shape galstka butterfly, but this name was already taken.
№8. SDSS J0100 + 2802 - the brightest quasar with the most ancient black hole
SDSS J0100 + 2802 - a quasar, located in 12, 8 billion light-years from the sun. It is notable that feed his black hole has a mass of 12 billion solar masses, it is 3000 times larger than the black hole at the center of our galaxy.
The luminosity of the quasar SDSS J0100 + 2802 is superior to the sun in the 42 trillion times. A black hole is the oldest known. The object was formed in 900 million years after the alleged big bang.
Quasar SDSS J0100 + 2802, astronomers discovered in Yunnan Province of China with 2, 4 m Lijiang telescope 29 December 2013.
№7. WASP-33 b (HD 15082 b) - the hottest planet
Planet WASP-33 b is exoplanet white stars in the main sequence in HD 15082 Andromeda. The diameter slightly larger than Jupiter. In 2011, the planet's temperature was measured very accurately - about 3,200 ° C, which makes it the hottest known exoplanets.
№6. Orion Nebula - the brightest nebula
The Orion Nebula (also known as Messier it 42, M 42 or NGC 1976) - the brightest diffuse nebula. It can be clearly seen in the night sky with the naked eye, and it can be seen almost anywhere in the world. The Orion Nebula is located about 1344 light-years from Earth and is 33 light-years across.
№5. CFBDSIR2149 - most lonely planet
I opened this lonely planet Philippe Delorme with a powerful telescope ESO. The main feature of the world in that it is in space all alone. For us, accustomed that the planets revolve around the star. CFBDSIR2149 but not such a planet. She is the one closest to her and the star is too far to exert gravitational influence of a planet. Similar lonely planet before scientists were, but far prevented their study. The study of a lonely planet would "learn more about how planets may be ejected from planetary systems."
№4. Kruitni - an asteroid with the Earth's orbit identical to
Kruitni - a near-Earth asteroid, moving in orbital resonance with Earth 1: 1 intersects with the orbit just three planets: Venus, Earth and Mars. It is also called quasi-satellite of the Earth.
Kruitni was found October 10, 1986 by the British amateur astronomer Duncan Ualdronom using the Schmidt telescope. The first temporary designation have been Kruitni - 1986 TO. the asteroid's orbit was calculated in 1997.
Due to the orbital resonance with Earth, the asteroid flies its orbit for nearly one Earth year (364 days), that is, at any time, Earth and Kruitni are at the same distance from each other, as a year ago.
risk of collision of an asteroid with the Earth does not exist, at least in the next few million years.
№3. Gliese 436 b - hot ice planet of
Gliese 436 b discovered by American astronomers in 2004. Planet size comparable to the size of Neptune, the mass of Gliese 436 b is equal to 22 Earth masses.
In May 2007, the Belgian scientists led by Michael Gillonnay from Liege University discovered that the planet is composed mostly of water. Water stored in the solid state of ice under high pressure and at a temperature of about 300 degrees Celsius, which leads to the effect of "hot ice". Gravity produces tremendous pressure at the water, whose molecules transformed into ice. And even though the ultra-high temperature water is not able to evaporate from the surface. Therefore, Gliese 436 b is very unique planet.
№2. El Gordo - the largest space structure in the early universe
Galactic Cluster - is a complex superstructure, consisting of several galaxies. ACT-CL J0102-4915 cluster, with the unofficial name El Gordo, was opened in 2011 and is considered the largest cosmic structures in the early universe. According to the latest calculations of scientists, the system 3 quadrillion times the mass of the sun. A cluster of El Gordo is located 7 billion light-years from Earth.
According to a new study, El Gordo is the result of a merger of two clusters which collide at speeds of several million kilometers per hour.
№1. 55 Cancri E - diamond planet
Planet 55 Cancri e was found in 2004 in a planetary system sun-like star 55 Cancri A. Weight planet the size of Earth masses almost 9 times.
The temperature at the side facing the parent star is + 2400 ° C, and is a huge ocean lava on the shadow side temperature is + 1100 ° C.
According to new research, 55 Cancri e in its composition contains a high proportion of carbon. It is believed that a third of the planet's mass up thick layers of diamond. In this case, the water in the composition of the planet is almost there. The planet is 40 light years from Earth.
