Mars Asteroid Hit 200 Times a Year
NASA recently revealed that the planet Mars was more frequently hit by asteroids and comets than previously thought. Mars was hit by asteroids many as 200 times each year. The average asteroid that hit the planet measuring 1-2 meters.

It Able Star Forming Galaxies Hundreds of Times Faster than the Milky Way |
Astronomers recently managed to find a galaxy that turns into gas that is around the stars. This unique galaxy burn the gas to reach the level of 100 percent combustion efficiency. Astronomers found the galaxies after making observations through the IRAMPlateau de Bure interferometer in the French Alps, NASA's Wide-field Infrared Survey Explorer (WISE) telescope Hubble and NASA."The galaxy gas burning engines similar to gas-powered cars and galaxies that have a" machine "highly efficient gas" said Jim Geach from McGill University as the lead author of the study in the journal of astrophysics. "This galaxy is like a sports car, the difference between a galaxy's gas change at the level of change in the most efficient," he added.Galaxy named SDSS J1506 +54 was discovered when astronomers looking at the survey data generated by the WISE infrared and infrared galaxies have so obviously that is equivalent to a thousand billion times our sun. "Because WISE was able to observe the entire sky, the galaxy is seen very clearly from other objects," said Ned Wright of UCLA as the principal investigator of WISE."These galaxies formed their stars hundreds of times faster than our Milky Way galaxy and it is the most extreme star formation," said Jim Geach. Astronomers using the IRAM Plateau de ure instrument interferometer to measure the amount of gas available in the galaxy. The result is detected the light waves of carbon monoxide as an indicator of the presence of hydrogen gas is the fuel of stars.Of these data with the data then astronomers menggabungkannnya WISE and Iram (to measure the mass of gas) and the astronomers were able to get a measure of the efficiency of star formation. The results show that afisiensinya reached the maximum theoretical known as the Eddington limit. Appropriate areas of new star formation, then the nearby gas clouds collapse due to gravity.When the gas condenses and have the power to push the atoms to trigger nuclear fusion reactions, the new stars will be born and at the same time the wind and radiation of new stars that can prevent the formation of new stars other by pressing the gas around it to prevent collapse clouds and larger gas.Eddington limit is the limit of the point where the force of gravity pulls gas simultaneously balanced with the amount of pressure coming out of the star. If it exceeds the Eddington limit wan gas will explode and the star formation process will be stalled. "We see the gas flowing out of the galaxy is millions of miles per hour and gas is likely driven by the strong radiation of the stars that were there," said Ryan Hickox, astrophysicist Dortmouth College, Hanover.It causes a galaxy SDSS J1506 +54 is remarkable is its ability to produce very fast star and galaxy evolution period is also very short Yag possibility tersbuet galaxy is a merger of the two different galaxies. An estimated ten million years longer tersbeut galaxy will run out of gas and will turn into a large elliptical galaxy.

Gemini Observatory Use New Technique for Orion Bullets Photos |
Team of the Gemini Observatory successfully developed a technique for image object space. This time the object of shooting them is part of the Orion nebula called "Bullet Orion" (Orion Bullets).
Orion Nebula itself is a nebula that can be seen even with the naked eye. That's because the distance is relatively close to the Earth which is about 24 light-years away in the constellation Orion. Recent photos developed by researchers at the Gemini Observatory is the result of the development of image retrieval method previously called Altair. Altair is one of the instruments at the Gemini Observatory in 2007 and it used to take a photo of "Bullet Orion".
Benoit Neichel as the scientist who led the development of methods and systems of the Gemini Observatory said it was busy for a few years with the development of a new system that is possible to be able to take pictures of the sky objects more clearly. The new system called GEMS.
The result on 28 December, 3 days before the new year Gemini Observatory Bullets managed to photograph the nebula with stunning results. Her picture was 2.5 times and 16 times finer details.
To see the difference Orion Bullets photo taken in 2007 to 2012, you can see below:

Herschel telescope which is also known as the Herschel Space Observatory is a large telescope made and operated by the European Space Agency (ESA) which aimed to observe the process of the formation of galaxies in the universe, the evolution of galaxies, star formation and the interaction between
stars, the chemical composition of the atmosphere and the solar system, including planets, comets, and the moon, and to know the chemical composition of molecules in the universe. Herschel telescope was launched into space on May 14, 2009 from the Guiana Space Centre, France using the Ariane 5 ECA rocket.
Herschel telescope weighs 3,300 kg (3.3 tons) and is equipped with a giant mirror of 3.5 meters that is sensitive to infrared light and wave submilimeter (55-672 m). The telescope was placed at a distance of 1.5 million km from Earth.

Right on 29 April 2013, Helium as coolant Herschel telescope detectors in the telescope out and stop operating. ESA engineers decided to put it in orbit the Sun.
During operation, telekop Herschel has done at least approximately 35 thousand scientific observations and collecting more than 25 thousand hours of scientific data. The success of such missions successfully determine cause of it by water on planet Jupiter which was caused by the comet Shoemaker-Levy 9 in 1994, managed to find galaxies HFLS3 and other successful series of observations.
Currently ESA is preparing the next generation of the Herschel telescope SPICA.
Create admire Hubble Telescope: Extreme Deep Field
Create admire Hubble Telescope: Extreme Deep Field | New
Hubble space telescope could arguably be one of the best telescopes belong to the human race to date. Photos of the beauty of the universe objects taken using this telescope often make us wonder. One of them is a photo called Extreme Deep Field or abbreviated
XDF.Hubble XDF is a photo of a tiny spot in the sky that its contents about 5,500 galaxies. Its location is the center of the photograph Hubble Ultra Deep Field in the constellation Fornax, a small constellation in the southern sky near the constellation Eridanus and Cetus. XDF is created thanks to the Hubble telescope performance for 10 years, a total observation time of 50 days, 2 million second exposure time (exposure time), and 2,000 photos combined.
