Astronomers have directly photographed exoplanet around the star Kappa Andromeda in the same constellation.
The planet is located at a distance of 170 light years from Earth and is removed from the star farther from the Sun than Neptune (ie 30 AU). The very same star Kappa Andromeda is 2.5 times as massive as the Sun. Age of 20-30 million years, which scientists say indicates a typical planetary scheme of planet formation. First stars formed from the disk, and then the rest of it, the gas giant.
On the basis of origin, scientists are asked to name the open celestial body superyupiterom. Object Read more [...]
Among the many meteorites found on Earth, scientists have isolated the most interesting and rather rare type of meteorite space.
To this type belong meteorites, known as "Pallas" (Pallasite). This is a unique type of iron-stony meteorites. They are iron-nickel base with frequent patches of greenish olivine crystals. These meteors are named after the German-Russian scientist Peter Pallas, who found a similar meteorite near Krasnoyarsk.
These meteorites look fantastic. They are similar to semi-precious stones of unusual beauty.
Today, scientists are divided these meteorites (pallasites) Read more [...]
Due to the ejection of matter by the black hole, located in the core M87, the galaxy formed a shock wave, and her remains previously unknown extensive cavity. And it sounded (Figure NASA / CXC / SAO).
Orbital observatory recorded something unexpected - a terrible roar emitted by a supermassive black hole. It would seem that the sound in a vacuum - how is that possible? Moreover, from a black hole, from which not that sound and even light signals will not wait. Still waiting. And no!This unconventional literally opening could do as a result of one of the long-term observation of M87 - our Read more [...]
Despite the fact that he is one of the brightest objects in the night sky, Mercury - a planet that experienced amateur astronomers observed quite often. In the next couple of weeks, however, observers from the northern hemisphere will have the best opportunity in 2013 to consider a small luminous spot Mercury in the evening sky.Feature observations of Mercury is that you should first find a place to watch the western horizon with unscreened, wait half an hour after sunset to dark, and then bring the binoculars at the sky, which lies just to the left of where the sun disappeared. After you have Read more [...]
Swedish scientists from the University of Gothenburg have found similarities between the Martian landscape with a polar archipelago located in the northern part of Norway.
Scientists say that the ancient water on Mars made its landscape-like terrain of Svalbard, which is located in the Arctic Ocean.
By assumption, the researchers, some areas of the northern and southern hemisphere of the Red Planet have similarity with this archipelago since ancient water that once flowed on Mars is frozen, then re-melted.
This confirms the fact that the water on Mars played a key role in shaping the planet's Read more [...]
Cosmic rays constantly bombard the Earth, splitting atoms in the outer atmosphere. Sometimes, however, the big cosmic events can have a more significant effect on our planet.Gamma-ray bursts are often regarded by scholars as the events that can lead to catastrophic consequences, are one of the most powerful single explosions in the universe: they are so powerful that we can see them, being on the other side of the universe. Now, researchers say that the rays coming from one of these bursts, bombarded Earth about 1,200 years ago.Last year, the researcher named Pusan Miyake opened soerzhaniya unexpectedly Read more [...]
November 17 at 09:30, Moscow time, the Leonid meteor shower peaked action. Hourly dark sky can rascherchivat thousand (!) White meteors. Leonids? very fast meteors (71 km / s), burning up in the atmosphere, they leave a bright glowing trail.Experts point out that the best conditions for observations come in the second half of the night. However, the most beautiful evening meteors are considered rare.
Ancestor of a meteor shower is Comet 55 / P Tempel - Tuttle. In 1998, tailed wanderer passed perihelion and is now moving to the outer limits of the solar system. Her return is expected only Read more [...]
Hydrothermal cracks around Martian impact craters could be suitable places for living organisms, according to scientists.The new study, conducted jointly by the University of Leicester and the Open University, led by lead author John Bridges of the University of Leicester has determined that the temperature on Mars were in the range of about 50 to 150 degrees Celsius. On Earth, microbes can survive in such an environment, such as the volcanic thermal hot springs of Yellowstone National Park, USA, suggest the researchers.The scientists analyzed samples of one of the types of meteorites, called Read more [...]
"Jupiter during the month will rise all before" - says Jane Houston Jones of NASA's Jet Propulsion Laboratory - "and there will be a sunset at the end of the month." Jupiter rises in the constellation of Taurus, as we see on the Schema. This is the brightest object in the sky in November. In a telescope are also visible moons of Jupiter. Further, the video tells about the upcoming mission, "Juno", which will help the astronomical community to learn more about the phenomena on Jupiter. The unit should go into orbit Jupiter in 2016. Below is a Taurid meteor Read more [...]
According to the data transmitted rover Curiosity, the radiation levels on Mars, roughly correspond to the parameters that occur in Earth orbit, including the ISS. Consequently, future colonizers of the Red Planet should not have major problems with radiation emission when working on Mars for a six-month mission they receive about the same amount of radiation as the ISS.
Similar findings at NASA made on the basis of the first studies on the surface of Mars. As described in the U.S. space agency, the rover Curiosity - this is the first device that actually measures the background radiation directly Read more [...]
Several unusual craters were found on the surface of the device Messenger Mercury. According to the NASA, craters are structures that have not been observed previously in the solar system. The surface is covered with craters, something like a "wrinkles." Something similar can be seen in the cooked pumpkin pie, astronomers say.Simulation of the formation of craters found that "cracelures" in craters in the northern hemisphere of Mercury may have formed as a result of flooding impact craters by lava flows and rapid cooling, reports New Scientist."Nothing of the sort we Read more [...]
MRO HiRISE camera device found on Mars traces the recent fall of the celestial body, According Astronomynow. Clashes with the red planet was discovered by scientists at Arizona State University in the analysis of images of the Martian surface, obtained at different times. According to astronomers, the celestial body could fall in the period from August 2005 to November 2010.Crash Site is a collection of several craters of different sizes. The presence of several craters due to the fact that the object is broken up into several parts in the atmosphere of Mars.

Record holder-survivor NASA Opportunity rover sent to Earth image that has puzzled scientists. In the photo section of the Martian surface can be seen dotted with numerous spherical structures. Martian bumps similar to those in the form of structures called "blueberries" and found rover in 2004. However, the newly discovered areas differ significantly from the "blueberries" in their composition. Currently Opportunity explores outcrop Kirkwood in Cape York on the western edge of the crater Endeavour. It was there and had discovered a mysterious sphere of 3 mm in diameter. Read more [...]
American rover Curiosity drew a map in the crater Gale winds with REMS meteorological instrument, and confirmed that the atmosphere of Mars is its only "shield" from space radiation, said the press conference at NASA's Jet Propulsion Laboratory on Thursday.'Judging by the shape of the crater Gale, we expected that the wind will blow it in two directions - toward the mountains and away from Sharp. It turned out that the winds are blowing in a completely different direction - on the edges of the crater"- Said meteorologist Clara Newman (Clara Newman) from research company Read more [...]
According to a leading astronomer at Harvard University Courtney Dressing, scientists do not have to look for habitable planets far away - perhaps they are very close. Dressing according to the calculations, habitable planet rotates in orbit dwarf at a distance of 13 light years from Earth. When flying at the speed of light in half to fly to a planet and back can be "only" 50 years, that is, within a human lifetime.
"We thought that to detect a habitable planet, we need to look for worlds at a great distance - said Courtney Dressing. - But now we understand that, most likely, Read more [...]
February 15 is very close to Earth will fly 45-meter asteroid. Afraid of this event is not necessary, although at some point the celestial body will be closer to Earth than many weather satellites and communications satellites.
