Asteroid 2012 TC4 pass by Earth at a distance of 95,000 km

An asteroid the size of a house will pass very close to Earth today, as scientists have caution. However, in spite of the fact that the space is very close, the scientists insist that there is no risk of collision with our planet.

Asteroid 2012 TC4 held at a distance of only 95,000 km from the Earth, which is about a quarter of the distance to the Moon at its maximum proximity to the Earth. This asteroid was discovered by astronomers October 4. NASA scientists will be watching it from the lab Jet Propulsion Laboratory in Pasadena, California.

Verification a new supernova black hole

In space telescope NASA "Swift" fixed-ray flashes, indicating the discovery and the survival of a new black hole, which was previously unknown. It is located at 20-30 thousand light-years from Earth. Flash X-ray peak of the supernova occurred on September 18. Flash output is 10 thousand volts, but two days of observation exposed that the radiation has increased by 30 times.

The red giant, to learn the fate of our Sun

In space, astronomers found a red giant, around which formed a three-dimensional spiral out of gas. R Sculptors dying star is 1.5 thousand light-years from Earth. Red giant looked through the telescope ALMA in Chile.

Red giants are the latest stage in the evolution of stars. At this stage the star expand and add to its mass, then the mass of stars scattered into space by stellar winds, spreading the substance of the universe, which is necessary for the formation of new stars. After 10-50 thousand years in the red giant burns helium, which is why there is a powerful release of gas that lasts for hundreds of years?

Songs of the Big Bang

It is known that the universe after the Big Bang has undergone swift increase, during which its volume increased to a staggering 80-degree! Universe and then continued its extension, but the recent increase in size was accelerated, resulting in a region of the universal signal extended outside.

For "writing" a detailed history of the expansion in the boss method, called "baryon acoustic oscillations-oscillations" (BAO). Physicists call ordinary baryons and all the usual matter.

Star cluster for the first time found a pair of black holes

M22 star cluster in our galaxy is located at a distance of 10,000 light-years from Earth. Administer to make a discovery by observing a super-large array radio telescopes located in New Mexico.

U.S. astronomers have detected about two separate black holes in the same star cluster M22, located in the constellation Sagittarius. The paper was published in the journal Nature, a summary of its results ScienceNow.

The consequences of a solar flare earth will feel tomorrow

Circumsolar space before the unit SOHO recorded a powerful solar emissions, which arise on the surface of the Sun. As reported by the NASA, solar flash was directed toward Earth, but a cloud of release came out very wide, and the concentration of the radioactive material in it is not too high.

In the solar system has been thrown out several billion tons of solar particles that reach the planet in about Monday. Theoretically, this can affect the performance of communication systems, satellites and electronic equipment. The first electromagnetic disturbances in the atmosphere of our planet can be tomorrow morning.

Powerful magnetic storm on Earth continues to grow

Today, 30 September, in the afternoon on the Earth strike a powerful magnetic storm, which not only affects the health of people but also can spoil communications systems, satellites and electronic equipment?

Recall that a space apparatus circumsolar SOHO recorded powerful solar emissions, which occurred on the surface of the Sun.

Earth is younger than the other planets, so it's a life

Abdulmyanov Tagir Raisovich, candidate of physical and mathematical sciences DEs (Kazan Power University), September 27, 2012 at the next European planetologicheskom Congress in Madrid, Spain, presented the results of their research in the field of shock waves, which, as expected, in the early solar system generated the young Sun.

The Indo-Australian lithosphere plate cracked in two

Because of a series of the strongest earthquake near the Indonesian island of Sumatra split Indo-Australian lithosphere plate, which, according to scientists, can lead to disasters throughout the world, which will continue for several years?

A series of aftershocks occurred in April of this year. It led to a split in the Indo-Australian lithosphere plate in two. The results of observations of scientists published in the journal Nature.

Impact of the black hole will destroy Earth in 2014

According to astrophysicists, the Earth is forthcoming cloud of unknown origin, which deletes everything in its path. It came from a black hole - at a distance of 28 000 light years from earth. Astronomers are watching for a celestial body, they say that they have found a strange bunch, which has been dubbed "sowing chaos cloud" - it destroys everything in its path: comets, asteroids, planets and stars. Now he goes to Earth.

Get the most accurate picture of Pluto, made with Earth

The planet, dwarf planet or Kuiper Belt objects, so what's the difference? The main thing that astronomers the most detailed picture to date of Pluto ever do with ground-based observations.

And that's how they got it:

They did a series of pictures of Pluto and Charon, using a newly developed camera called Differential Speckle Survey Instrument (DSSI), which is mounted on an 8-meter telescope of the Gemini North, located in Hawaii. 

The distance from Earth to the Sun, finally identified

How far the Earth is from the Sun? This apparently simple question is actually a matter of dispute scientists for over a hundred years.

How to solve a specific point on the Earth to measure? How to determine what distance from the Sun to calculate - up of vapor or flames?

Earth in the third dimension

The German satellite TanDEM-X was launch into orbit on a mission to map more accurate to be made available to the surface of the Earth. The satellite will fly radar technology with identical platform called TerraSAR-X launched in 2007. Both measured variations in the height of the globe with an accuracy of better than two meters.

Its digital elevation model will have many uses, from helping military jets fly ultra low height to show where rescue workers was worse the damage caused by an earthquake.

ESA astronaut André Kuipers returns to Earth

Six-month historical during PromISSe mission on the International Space Station, André Conducted over 50 scientific experiments in the world's only permanent microgravity laboratory.

Now that the orbital outpost is Fully Assembled, astronauts on the Space Station can devote more time to research.

Astrophysicists do not rule out Earth-like planet found before the 2022

Astrophysicists do not regulation out judgment within ten years a small planet like Earth said today Ignaci Ribas, one of the organizers of the "Cool Stars 17", the international meeting on cool stars in Barcelona brings together the best experts in this type of stars.

Rivas said in remarks to Efe already  identified  more  than  800  planets around cool stars, and that is very close to finding one that is very similar to ours.

Where did the water on Earth?

Extensive before that scientists began to wonder about the origin of water on Earth . And so far the official maintained that the volatile elements (such as hydrogen, nitrogen or carbon), and even the first organic matter, arrived here from abroad , contributed by comets and meteorites by class of origin very old, the carbonaceous concretes . Both classes of objects are formed beyond the orbit of Jupiter and "migrated" then into the Solar System.

A large solar flare reaches Earth

The huge AR 1520 spot with a diameter ten times that of Earth, launched an X-flare 1.4, within the highest level in the intensity scale (there are A, B, C, M and X, points which is a number from 1 to 9). Whiplash has caused a coronal mass ejection (CME), a fiery cloud of particles and radiation that could affect Earth, as explained by the Space Weather Observatory.

The blaze has had consequences in South America, Central America and parts of the Caribbean, where there have been radio blackouts R2 level (high level).

The day of the year when the Earth is farther from the Sun

There was the phenomenon known as aphelion , which occurs each year between March and July 5. This means it is the day of the year when the sun is farthest from Earth.

Although visually it is imperceptible, with a special telescope experts can see that the sun looks smaller. Precisely, is 3 percent less than its normal size.

According to experts, the effects of this are changes in the tides and a possible decrease in solar energy , but has no effect on the climate, or severity of the Earth.

The oldest crater on Earth is in Greenland

European Geologists have found the oldest impact crater on Earth in the city of Maniitsog (Greenland). This is a crater 100 kilometers in diameter caused by the fall of an asteroid 3,000 million years ago. Experts suspected the existence of the crater since 2009, when the Geological Survey of Denmark and Greenland, examining a geological map of the surrounding Maniitsoq, discovered strange anomalies in the structure of the local rocks, caused by the impact of a giant meteor .

The first Frenchman in space

In 1982, Jean Loup Chretien became the first French astronaut to travel into space to orbit the Earth to the Soviet space station Salyut 7. Salyut, which means "hello" would be the predecessor of the space station Mir famous, which would mark a record stay in space.

Chretien was not only the first French astronaut, but the first foreigner to participate in the program space of the Soviet Union.Currently Chretien retired engineer, working on new technologies and has brought rave reviews supporting the creation of the Mexican Space Agency, AEXA, joining such an initiative.
