Scientists say, dinosaurs became destroyed as a result of comet impact, not an asteroid

Space object which wiped out the dinosaurs 65 million years ago, it might be a comet impact, not an asteroid, a new study indicates.

180-kilometer Chicxulub crater, located in Mexico, was established as a result of the collision, which led to the extinction of the dinosaurs and about 70 percent of all species on earth, according to many scientists.

The spacecraft for the collision of an asteroid in 2022

Scientists from Europe and the U.S. to confidently move promote in their plans to make a deliberate collision of a spacecraft with a giant asteroid in 2022 to look into the depths of such visitations.

Ambitious European mission Asteroid Impact and Deflection Assessment, or AIDA, consisting of two satellites (one of which will be built by scientists from the U.S., and the second - the European Space Agency), is scheduled to start a three-year journey to the asteroid Didymus and his companion. Didim not dangerous for the Earth, so it is well suited for this kind of research, scientists said the mission at the 44th Annual Conference of the moon and planets, on Tuesday, March 19.

MESSENGER sees the smooth side of Mercury

During the two years of its location in orbit around Mercury, NASA's MESSENGER spacecraft has made ​​more than 150,000 images of the planet closest to the Sun, the solar system, first giving us the opportunity to think about the extremely rough, parched surface of the planet in feature. But not all areas on Mercury look stern and sinister: it also has a smooth side, you can see on the picture, published today.

Here we see the smooth sides and bottom Mercurian irregular depressions in high definition. 

The new company SpaceX rocket prepared for launch, scheduled for the summer

The next generation of rocket company SpaceX is prepared to fly, and it was probably he will be used to launch commercial spacecraft, which will take place this summer, the company announced Wednesday.

Merlin 1D engine was declared ready for flight once it passed the ignition for a total of 33 minutes for the 28 different tests on the premises for the development of rocket company SpaceX in McGregor, Texas.

In April, the Sun will stop distribution the commands to Mars mission

The planets in the next month will worsen due to the Mars mission. Mars will be almost exactly behind the Sun when viewed from Earth. The sun can easily interrupt the broadcast between two planets when the three celestial bodies line up in one line. To prevent incorrect signaling, dispatchers from NASA Jet Propulsion Laboratory intend to suspend sending any commands to all the Martian rovers and orbiters in April. Transmission from Mars to Earth, too, will be kept to a minimum.

Star and a black hole revolving in rapid waltz

Space Telescope European Space Agency's XMM-Newton helped discover a star and a black hole that address near each other at high speed, making one revolution in just 2.4 hours - which is an hour shorter than the orbital period of the previous record holder.

A black hole in the close pair, known as the MAXI J1659-152, at least three times as massive as the Sun, while the mass of its companion star - a red dwarf star - only 20% of the solar mass. 

Curiosity meet hill of Mars

Following spend about seven months on Mars; NASA's rover Curiosity all the time explored the area surrounding its landing zone, studying the Martian surface with its inspiring weapon store of scientific instruments. For about 208 Martian days, or nightingale,
