The new twin of our solar system

admin — Sat, 25 May 2013 22:07:18 +0000

The Brazilian astronomers reported about opening of the new twin of our solar system. The Brazilian scientists from Rio Grande do Norte University officially reported about opening of almost identical twin of our solar system. The star similar to our Sun is called as CoRot Sol 1. Now our Sun has any more one twin. Gradually scientific opens more and more stars similar to the central star of our Solar System. The solar twin received CoRot Sol 1 designation as it was open with help of the space Corot satellite started on 2006. The star of CoRot Sol 1 is today the most remote Twin of our Sun. Just as our Sun, its' remote twin is the yellow dwarf. This SP of small stars of the main sequence having weight from 0,8 up to 1,2 weight of the Sun and temperature of a surface 5000-6000 K. According to the name, by results of a photo material they have yellow color; though subjectively their color is perceived by the person as the purest white (hotter stars will be perceived by the person as bluish or blue). The main source of their energy is thermonuclear synthesis of helium from hydrogen.

The first topographic map of Saturn satellite Titan

admin — Sat, 25 May 2013 21:24:15 +0000

Scientists collected a first-ever global topographic map of the Titan, the largest satellite of Saturn, using radar pictures from NASA spaceship. The new topographic map of the Titan represents the gathered pictures and data of radar of the spaceship of Cassini. It shows an unprecedented view of a surface of the Titan and has to help scientists to learn more about one of the heavenly bodies most similar to Earth in Solar system. By the words of Ralf Lorent (the member of team of the spaceship Cassini from laboratory of applied physics to Lorel, the State of Maryland) on the Titan there is a lot of interesting things: fluid liquids and movement of sandy dunes. But to understand these processes, it is necessary to know a district inclination. It is especially useful for those, who studies a hydrology and modeling of climate and weather of the Titan for which it is important to know about heights or lowlands for creation of models.

At the end of the month the big asteroid will fly by the Earth. It will be the asteroid’s greatest rapprochement with our planet for the next two centuries. On May 31 the asteroid 1998 QE2, which diameter makes about 1,7 miles (2.7 km), will fly by the Earth and doesn't pose threat. The space stone will fly by at distance of 3600000 miles (5800000 km) from our planet - in 15 times more distances between Earth and the Moon. Astronomers, who plan to consider 1998 QE2 with help of two huge telescopes, wait for uneasy the approach of asteroid. Every time when the asteroid comes nearer, it provides opportunity to scientists in details to study it to understand his sizes, a form, rotation, features of a surface. This information can tell us about its origin. Also we will calculate diameter of an asteroid and its speed with help of Goldstoun to improve the calculations of the orbit and to calculate future trajectory of asteroid movement.

The telescope opened an improbable fiery ribbon in the nebula of Orion

admin — Thu, 16 May 2013 16:48:00 +0000

In Chile the telescope took the tremendous new picture of the space tape flickering in a nebula of Orion more than in 1000 light years from Earth. The new image published by the European southern observatory today (on May 15).The scientists described as "a fiery ribbon" red gas and a dust, shining in a belt of constellation of Orion. Tape is a small part of huge area of a star formation in the Universe. Scientists of ESO used a telescope in Chile to process video about a cloud of a dust, which unites to create new stars. Big light clouds in the top right corner of the image are known as a nebula of Orion, which also is called as Messier 42. The nebula of Orion is the brightest part of a huge star, where new stars are born, and is the closest massive region of a star formation to Earth Though on the image the clouds of red dust and gas can look heated, actually they are cold. APEX telescope in Chile took the picture in lengths of waves invisible to a human eye. On this image the hottest blue luminescence, while the coldest have an orange shade. More neutral of tone on a photo show the same site of the sky in a visible range of light. On this image the fiery ribbon disappears from a look, because the cooled particles of a dust block flickering light.

The Most powerful solar storm on May 12

admin — Tue, 14 May 2013 18:03:53 +0000

People of Earth were lucky that the most powerful solar flare, which took place on May 12, was on the other part of the Sun. On May 12 on the Sun was observed one of the most powerful solar storm of 2013. It was recorded by sensors of orbital Observatory Solar Loudspeakers (SDO). The purpose of this program is development of the scientific knowledge necessary for the effective solution of aspects of Solar and Terrestrial communications, which directly influence life and society. Solar storm was referred to the class X1.7. The class X is the most intensive level of solar flashes. The index specifies value of intensity of flash and can be from 1,0 to 9,9. Such powerful solar storms can pose serious threat for ISS crew, and also for the complex of a space station and other space satellites. Worst of all that such flashes can't almost be predicted in advance.

Telescope Hubble found two unique white dwarfs

admin — Sat, 11 May 2013 19:32:13 +0000

Before emergence of the serious technical problems connected with full leakage of liquid helium on a space telescope Hubble, it managed to make one more important and interesting opening. Hubble found two stars, which already finished the evolution and turned into white dwarfs, at distance about 150 light years from Earth. In comparison with ordinary dwarfs, who has quite neutral atmosphere, the atmosphere of these two stars has a set of elements - construction blocks, which are responsible for formation of firm planets. These two stars were found by tools of an orbital telescope in Hyades scattered star congestion in constellation of the Taurus. Age Hyades makes about 625 million years. According to the researchers from the Cambridge University for them became a big surprise when they found construction elements in the atmosphere of two white dwarfs found telescope Hubble.

Astronomers found hydrogen gas clouds – the bridge between the galaxies

admin — Fri, 10 May 2013 19:26:04 +0000

In intergalactic space astronomers found huge threadlike clouds of gas from the ionized hydrogen, which can be the indicator of thin threads from the dark matter connecting cells of global space. The previous cycles of supervision over empty space between galaxies indicated of possibility existence of clouds of hydrogen between them. But the astronomers couldn't determine the sizes of these hydrogen gas clouds and their property. With help of a radio telescope Green-Bank the astronomers were succeeded to understand that it not shapeless clouds, but quite accurate structures. For several weeks the astronomers watched the closest neighbors of our Milky Way, Andromeda's galaxies and the Triangle. These "star megalopolises" drew attention of astronomers still a year ago, when they found in data of radio observations hints on existence of big congestions of hydrogen in intergalactic space. According to astrophysicists, all these clouds are located along the line connecting Andromeda and the Triangle.

Mountains on Mars are created by a wind

admin — Tue, 07 May 2013 19:14:28 +0000

Scientists came to a conclusion that Winds on Mars influenced its landscape more, than water. According to researches of the American Mars rovers and the European prospecting probes, the mountain on Mars has very peculiar form. Proceeding from all obtained data, after their careful analysis, scientists came to a conclusion that at all water, and a strong wind created mountains on Mars. Many scientists assume that the 5,5-kilometer mountain Sharp was also formed by numerous and powerful Martian winds. The group of scientists of Princeton University and the Californian institute of technology showed that formation of the mountain Sharp probably happened on the following mechanism: in the afternoon the air heated by the Sun, rose from a crater bottom, and by the evening process of return of air masses was observed back.

NASA registered the most powerful flash of Sun eruption

admin — Mon, 06 May 2013 05:47:45 +0000

Arrival of May is noted by fascinating solar eruption on the Wednesday, released the enormous wave of most powerful flash captured on the camera of the spacecraft of NASA. Sun eruption happened for the 2,5-hour period on Wednesday (on May 1) and was shown in "a huge running wave" on the Sun. Scientists call solar eruptions the emission of coronal weight - one of types of a storm, which can "shoot" billion tons of solar substance with a speed more than one million miles at an hour. When emissions are directed directly towards Earth, the most powerful flashes can constitute danger to satellites and astronauts in an orbit, and also to interfere with establishment of communication and navigation of networks. They even can damage land power infrastructures. But in day on the first of May eruption happened on the other side of the Sun and wasn't directed on Earth. It prepared the dazzling bright wave of the plasma, which has increased from a surface of the Sun, and then directed in an outer space. Though flash is directed not towards Earth, some scientists predict revival of geomagnetic activity. Now the Sun is in an active phase of the 11-year cycle and, as expected, will reach the peak of activity this year. The observatory of solar dynamics of NASA is one of several spaceships, which bears continuous watch at the closest star of Earth, and traces weather and storm on the Sun.

The asteroid 1999 RQ36 by the results of competition among school students received a new name[ad#Google Adsense-3 11] Bennu, in honor of an Ancient Egyptian deity heron. The asteroid (101955) 1999 RQ36 of 500 meters in size opened by scientists from the LINEAR project of Massachusetts Institute of Technology. In 2182 it will approach to the Earth. After "cancellation" of threat of Apofis and some other asteroids, it became the main potentially dangerous object for the Earth. Participants of the OSIRIS-REx project, for receive a name, which will be easier to be said, than 1999 RQ36, declared competition on the best name, which participants could become school students from any country of the world, but more younger than 18 years. On competition arrived more than 8 thousand options from school students from 25 countries. As a result the Committee on names of small bodies of Solar system of the International astronomical union accepted the option offered by nine-year-old Michael Puzio from Northern Carolina. The American asteroid project OSIRIS-REx for the USA will be the first program of research of an asteroid with help of an automatic probe.

Touch – reactive materials give robots a sense of touch

admin — Wed, 01 May 2013 16:20:52 +0000

For many years scientists of the whole world wants to find a method, which will give the chance to robots to perceive. The robot with the improved ability to feel has more opportunities for identification of objects, moves with bigger care and carries out more tasks as a whole. The latest step to achievement of this purpose was taken by researchers from Institute of technology of Georgia, developed new type touch a material, which is rather sensitive to compete about sensitivity of human fingers and can present to robots tactile sense, which reminds our own. The raised tactile material uses about 8 thousand piezoelectric effect transistors, each of which contains about 1500 nanowires, which diameter between 500 and 600 nanometers. Unlike the majority of touch screens, which measure change in resistance or capacity to find where your finger, these transistors feel change in their own polarity with a pressure. It is connected with nanowires from zinc oxide, which connect to electrodes a thin layer of gold that at the same time gives them piezoelectric and semiconductor properties. Within nearly three years the research group chemically raised hundreds massifs with sizes of 92 x 92 transistors, which are located vertically to create "taxels", which make separate electronic signals at a touch.

NASA Cassini spacecraft captured big hurricane on Saturn

admin — Tue, 30 Apr 2013 19:17:41 +0000

The big hurricane on a surface of Saturn, similar to a rose bud, captured the NASA Cassini spacecraft. Scales of the hurricane impress: its diameter makes 2 thousand km that in 20 times more, than the biggest hurricane on Earth. Cassini allowed researchers to make out for the first time a hurricane on Saturn in detail. Wind speed in the hurricane center as it became clear, reaches 150 m/second. Unlike terrestrial storm, which move on a planet, the hurricane on Saturn isn't mobile and is on its North Pole. On Earth hurricanes, as a rule, drift to the north, because of the turbulences of a wind caused by movement of a planet.

Comet ISON 2013 is the reason of new meteor shower

admin — Mon, 29 Apr 2013 21:46:55 +0000

By the word of scientists, the coming nearer comet, which can quite appear "A comet of a century", can create an unusual type of a meteor shower. When the comet of ISON 2013 will fly by Earth this year, it is quite possible that the dust from a tail of a comet will create a meteoric stream. In that moment to the atmosphere of a planet will get a stream of the smallest particles, which once were part of a tail of a comet. According to the Paul Veygert instead of combustion in light flash, they will softly drift down to the Earth. By the Veygert's computer model motes will travel with a speed of 125 000 miles/h (201 168 km/h) but as soon as they will get to Earth atmosphere, will be slowed down before total loss of speed. Because of it, observers on the Earth won't be able to see meteors as they fall through the atmosphere in January 2014, the scientist added. The invisible meteor shower of a comet dust, if it really occurs, will be very slow. It can take months or even years for the fine dust settling from an upper atmosphere. But the hope of brilliant show can't be lost.

Scientists found mysterious hot spots in a red supergiant star. Astronomers submitted the photo of an external layer of the atmosphere of a Betelgeuse star. It is the red supergiant next to Earth. It is very bright star located in constellation of Orion, which is the semiregular variable star which shine changes from 0,2 up to 1,2 star sizes and on the average makes near 0,7m. Red color of a star is easily noticeable at supervision by naked eye. The new photo of this star opens secrets of structure of substance, which proceeds from a star. In the photo on the right is visible the Betelgeuse star and her orbital circles. The photo was made by the camera of a radio telescope of MERLIN of Jodrell Bank Observatory. The Betelgeuse star is in 1000 of times massive from our Sun, but at distance of 650 light years from Earth, it still looks as a small point. In spite of the fact that it is a cold pro-evolving star, scientists found on it strange hot spots.

Asteroid 2013 GM3 will fly close to Earth in 2026

admin — Sun, 28 Apr 2013 11:58:28 +0000

In NASA deny calculations of the Italian astronomer and claim, that the probability of collision of an asteroid with Earth is insignificant. After 13 years, in April 2026, the twenty-meter asteroid 2013 GM3 will fly by in only 8,5 thousand kilometers from a terrestrial surface. The calculations, which have been carried out by the Italian astronomer Francesco Manka from observatory of Sormano testify to it. For the first time the asteroid 2013 GM3 was found on April 3 of this year by the scientists working at the American observatory of "Maunt-Lemmon". The laboratory of jet movement of NASA carried out calculations, which showed that on April 14 2026, at 13.30 across Greenwich this asteroid will fly by at distance of 39,7 thousand kilometers from Earth surface. However the Italian scientist conducted the researches: its calculations showed that appointment to heavenly "guest" can become "closer".

Rings of Saturn were attacked by rocks in space

admin — Sun, 28 Apr 2013 11:38:05 +0000

Rings of Saturn are continuously bombarded by rocks in space. Cassini spacecraft being in an orbit of Saturn since 2004, helped scientists to observe a picture of bombing of Saturn rings fragments of space rocks. Collision of these fragments with rings of Saturn lifts big clubs of a space dust and leaves traces in the form of hyphens on rings. It is well visible on the example of the photo of 2004, when the Cassini chambers recorded collision of rocks with rings of Saturn. Orbit of Saturn around the Sun is equivalent to about 30 terrestrial years. Approximately for the 15th year of this cycle, the night of Saturn becomes almost equal to day of Saturn. Just such period fell on 2009 that helped scientists to study in more detail better that happens to rings of Saturn.

The origin of water on Jupiter

admin — Fri, 26 Apr 2013 06:11:14 +0000

French astrophysics established that a source practically all water in a stratosphere of Jupiter is the comet Shoemaker - Levy 9, fallen to a planet in 1994. Conclusions of researchers are based on supervision over a stratosphere of the gas giant, carried out by means of a space telescope Herschel. Data were obtained in the infrared range, with lengths of waves of 66.4 and 179.5 micrometers, where water has characteristic peaks of radiation. In work were used the spectrometers of PACS and HIFI established on a telescope. Made on the basis of data Herschel the card of distribution of water in a stratosphere of Jupiter was not uniform: in the southern hemisphere its concentration was much higher, than in the northern. According to astrophysicists, such heterogeneity unambiguously says, that its source is the comet Shoemaker- Levy 9, which in 1994 entered just into the southern hemisphere. Scientists specify that the water rising within of a planet would be distributed evenly. To other, more uniform distribution lead also other alternative scenarios, for example, water drift from the outside together with a space dust.

NASA WISE telescope found a galaxy 30000 light years away

admin — Thu, 25 Apr 2013 17:04:16 +0000

NASA space telescope WISE found a galaxy in 30 000 light years away from us. The orbital infrared researcher of WISE, which belongs to the American Space Agency NASA, was launched into Earth orbit in December, 2009. Recently by this effective space telescope astronomers could find an unusual galaxy of color khaki. As it appeared, this galaxy has such color thanks to continuous transformation of galactic gas in all new and new stars. NASA WISE telescope with its opening was helped by space observatory Hubble, and also the interferometer Plateau de Bure located in the French Alps. According to author of research Jim Gikh from University Makzhil in Canada the galaxy which they found with help of WISE telescope, is really enough unusual. This surprising galaxy as much as possible converts the fuel, which is gas, in new stars. Level of this converting of gas in stars is nearly 100%. Thanks to the constant raised level of transformation of gas of a galaxy in formation of new stars, it looks green.
