Comet McNaught, taken very large scale north-European telescope in January 2007. Large comet collision with the Sun can cause disruptions to global electronics, which are usually associated with the work of a full-scale electromagnetic weapons or a nuclear exchange.At least, so says astrophysicist David Eichler, in his article, saying that a large comet roughly equal in size comet Hale-Bopp (the nucleus of about 30 kilometers in diameter) may be in a collision with the sun to generate cosmic shock waves that are large enough to cause electromagnetic global Armageddon.
Eichler, an astrophysicist Read more [...]
A year ago, the project was created Habitable Exoplanets Catalog - catalog of potentially habitable exoplanet, which was added at the beginning of the two worlds. According to Abel Mendez, of the University of Puerto Rico, in the year to the directory must be on only one or two of the planet, but after the first year of it was seven planets. Creation of such a directory, according to Mendes, is significant not so much for the scientists, but for the public as well as appearing regularly news of another planet in the habitable zone, but for each of the world would like to have a complete set Read more [...]
Some ancient cultures called them "Menace of the Universe" and "Harbinger of Doom." Comets are almost universally regarded as the ancient messengers or accept bad news from the gods.
In the midst of our busy lives, it's hard to remember that we live on a ball that flies through space around another, gaseous sphere, called the Sun, and it, in turn, is part of our galaxy. In ancient times, people could not get distracted by things like television and the Internet.
They looked at the sky and looking for it "keys" and "leadership" for life on earth, Read more [...]
Asteroid 2012 XE54 of about 50 meters, open in the U.S. project Catalina on Sunday, Tuesday fly next to the Earth at a distance of 224.9 thousand kilometers - about half the distance to the moon.
Asteroid 2012 XE54 was first discovered in the pictures of the American Review (Project "patrolling" the sky in search of asteroids and other space objects) Catalina made at around 11:00 on Sunday. Later discovery was confirmed Observatory of the Hungarian University of Szeged, and the Japanese observatory Moriyama.
The object has been assigned to Class Apollonian asteroids - the type of Read more [...]
One black hole, they teach us, it is impossible to separate the two. However, as it turned out, it is possible that a pair of black holes can be divided into three or more. Much more.The second law of thermodynamics of black holes is prohibited to reduce the surface of the black hole (BH). Any partition of BH into smaller this surface will reduce that prohibits the above principle.
Mathematically, it all comes down to the fact that if A> 0, B> 0 and A + B = C, then A? + B? ? With? has no solution (as always, the phrase "no decisions" should not be taken literally, but in Read more [...]
10/12/2012 So, December 3, working with the Voyager 1 scientists presented the results of the current of the device, which allows us for the first time - albeit virtually - to cross the boundary of the solar system and consider everything that is happening in these areas. The probe revealed much new about them, and among the latest findings - the whole area of space, the existence of which still did not suspect. Voyager 1 has long crossed the shock, after which the particles of the solar wind slows down to below the speed of sound, and begin to move chaotically. In June 2010, the probe is 17 Read more [...]
Light from the most powerful energy source of the universe allows scientists to study the nature of space-time, watching the so-called gamma-ray bursts spacecraft Icaros Japan Aerospace Research Agency (JAXA). Photons released during these outbreaks, help to place restrictions on the combined model of all the forces of nature - what scientists call a "general theory of everything."Gamma-ray bursts - a giant explosions that occur when massive stars die or face each other neutron stars. By studying the polarization of photons of light coming from the gamma-ray bursts, a team of Japanese Read more [...]
To prepare for the meeting of a massive asteroid that could threaten Earth in the future, scientists propose to ram his spaceship in order to move an object with a dangerous orbit.According to the proposal presented on Wednesday, December 5, at the annual meeting of the American Geophysical Union, Andrew Cheng, a physicist from the Applied Physics Laboratory at Johns Hopkins University, the asteroid are encouraged not to send two spacecraft, one would have to crash into the asteroid, while the second will be watching this event and transmit to Earth on its findings.At present, the scientific community Read more [...]
Most of all exploding stars of type Ia. These supernovae all have the same properties, regardless of the settings of their parent stars. Of course, we need some uniformity of the initial data - it must be binary systems consisting of a white dwarf and some other stars. But the values of the masses and the distance between the stars can vary over a wide range, and yet they will explode the same way. This consistency allows the properties of Type Ia supernova explosions as a means to measure distances in the universe. That's why it was opened by the sad fact - the accelerated expansion of Read more [...]
Tautatis asteroid fly at 10:40, Moscow time, on December 12, at a distance of only 6.93 million kilometers from Earth. Observation of a celestial body will lead to U.S. researchers. Their mission - to obtain radar images of resolution of less than 7.5 meters. To do this will involve the world's largest radio telescope Arecibo.
The next day - a month ahead of schedule - at a distance of several hundred kilometers from the Chinese Tautatisa fly apparatus "Chang'e-2." This will allow him to take pictures with a resolution of a few tens of meters, according to "RIA Novosti".

10/12/2012Employees of the Pulkovo Astronomical Observatory of RAS for the first time found evidence of the presence of a strong magnetic field in the accretion flow of the star system.
Previously, something like that was revealed only in relation to black holes and neutron stars.In 1971, the Soviet physicist Victor Schwartzman first showed that the presence of a strong magnetic field in a substance, addictive black hole, could significantly change the process of absorption in general. Own magnetic field flux, under certain conditions, is able to stop the fall of the substance at a distance Read more [...]
Comet 168P/Herdzhenrotera, reached the inner solar system, disintegrates. This event is reported by astronomers from the observatory Remanzacco, observed the object on October 26, with the aid of a telescope Faulkes. The disintegration of the comet also later recorded by the National Observatory Kitt Peak Observatory and NOAO. Observations made with the Gemini North Telescope Observatory NOAO, showed that the comet was separated from at least four pieces, and the head part of the comet was much brighter.The comet is currently visible in large telescopes in the night between the constellations Read more [...]
This short video clearly visible trajectory of "new guest". Kometaa found on frames taken with the camera by NASA Stereo Behind HI-2. By meniyu's "massive object with the tail seems to be moving toward Earth at high speed." "It's not like a typical inhabitant of the solar system." This object is clearly visible on the equipment by NASA for the past few weeks. However, NASA has not yet made any statements on this account, except denials "end of the world." In the coming days we will be able to detect objects in the image camera NASA HI-1 Stereo Read more [...]
Immediately after approaching asteroid, February 16, the astronomers plan to hold a series of observations with the largest radio telescopes VLA (Very Large Array) and VLBA (Very Long Baseline Array), and NASA's planetary radar at Goldstone.U.S. astronomers plan to "feel" the radio waves 45-meter asteroid 2012 DA14, which is this Friday will fly very close to the Earth in order to accurately determine the parameters of rotation - it will predict the future path of the "guest," according to the National Radio Astronomy Observatory, USA.
Asteroid 2012 DA14 was opened in February Read more [...]
It was not even a meteorite, and a small splinter. However, the damage inflicted grave - a solar panel will probably need to be repaired. Micrometeors was so small that on Earth, its rapprochement with the space station is simply not noticed. And they could not see.
