Record breaking flies from black hole

Quasars are very distant galaxies with extremely luminous core areas. Astronomers believe that massive black holes are the source of kvasarernes high energy show.

The supermassive black holes in quasars create such strong and very energy-rich effluents of material ejected and affect their surroundings. Astronomers have now found the most energetic outflows from a quasar ever.

Gigantic black hole surprise

Astronomers have discovered a giant black hole that is surprisingly heavy in relation to the galaxy hole live in. Super Heavy black holes in galaxies are typically several million times heavier than our Sun. But now, astronomers have found a black hole that is 17 billion times more massive than the Sun! The giant black hole at the heart of a galaxy called NGC the 1277th.

Three planets in a row

Currently seen the planets Mercury, Venus and Saturn in the morning sky before sunrise the third December is the three planets in a row.

Currently performing the three planets Mercury, Venus and Saturn a cosmic dance in the morning sky before sunrise. Thus stood Venus and Saturn very close together on 27th November, but clouds blocked unfortunately, the view of the planet parade.

If it is clear weather on Monday, the 3rd December, it will be possible to see Mercury, Venus and Saturn in a row with Mercury at the bottom, Venus and Saturn in the middle at the top.

A unique mega-storm at the north pole of Saturn

Spacecraft Cassini recorded an incredible storm that engulfed the famous hexagon on the north pole of Saturn. The diameter of the storm more than 30,000 kilometers.

Unique video probe sent to Earth on November 27, according to NASA. He had previously recorded storm in the northern part of the planet, but only in the infrared, because it was dark.

As they note, the image of the swirling vortex "cause illusory sense of rotation" of Saturn. 

Astronomers suspected end of the world disappoint their entire daily

Astronomers believe that December 21, 2012 - the day that very mistrustful people waiting for the end of the world - will be the most common. According to them, the Sun will have no outbreaks, and will not even magnetic storms.
"Even the magnetic storms on that day will not be", - said the director of the Astronomical Observatory of Irkutsk State University Sergei Yazev.
According to him, Russian scientists from Irkutsk, Moscow and Novosibirsk watched a total solar eclipse on the northern coast of Australia. 

In Scotland, found a house built 10,000 years ago

In the north-west of Edinburgh, near Queensberry in the construction of a road bridge over the River Forth were discovered the remains of a prehistoric house built more than 10,000 years ago.

"The construction of the bridge, designed to facilitate the development of Scotland in the future, it helped to understand the past, "- says the opening of Scotland's Transport Minister Keith Brown.

The Galapagos Islands found relatives extinct giant tortoise

The death of the world famous turtle named Lonesome George, the last of which was considered Abingdonskih elephant skulls, not to have disposed of its kind, as previously thought.

The researchers found that live on the Galapagos Islands, at least 17 turtles, which are similar to George genetic traits, including individuals of the same is kind to him.

Naked black widow star with orbital period shorter

Although Earth takes 365 days to complete its orbit, the newly discovered pulsar does PSRJ1311-3430 in just 93 minutes, making it the neutron star in a binary system with the shortest orbital period calculated to date. It is also the first discovery of a millisecond pulsar conducted through its gamma-ray emission.

The peculiarities of this new order they are listed in the journal Science.

How much water is on Earth?

How much water do you think there are on Earth? Approximately 70% of the surface of the Earth is covered by water, and oceans contain about 96.5% of all water from the planet. But there is water in the air as water vapor, in rivers and lakes, ice caps and glaciers, as moisture in the soil and groundwater, even in your body and your dog. However, all that water is in the "small" area of ​​1,385 km in diameter.

The Earth will not end in 2012

On December 31, the Gregorian calendar did something frightening. He spent the years 2011 to 2012. What we experience as the year came to an end? Earthquakes? Globally? A planetary collision? Stranger gravitational effects caused by an alignment with the galactic plane? Is the impact of a comet? 'Lighting' Earth?

As much as I wish it were true finally, it is likely that the New Year celebrations only involve a lot of alcohol and fireworks. It is the beginning of a new year for our calendar. Nothing more, nothing less.

End of the world in December 2012, interviewed NASA scientists

Is December on the doorstep? Does this mean that awaits us last month of life on this planet, and whether a doomsday in 2012? We interviewed NASA scientists and their response surprised us. Read the article - it's interesting!

During the entire existence of mankind been countless theories about how our planet will cease to exist. 

Mars was found gutters on Phobos

The Martian satellite Phobos could be the result of contact with Phobos debris ejected from the craters of the Red Planet during its bombardment by space objects, a new study indicates.

To explain the nature of the mysterious troughs are abundantly present on the surface of Phobos, in 2011, a group of American scientist John Murray has been proposed, 

Astronomers, discovered a planet, 13 times greater than Jupiter

This finding sheds light on the formation of new planets. Mass of the new planet is 13 times greater than the mass of Jupiter, the largest planet of the solar and heavy systems. Previously, scientists doubt that the planet can be formed from a protoplanetary disk as massive stars, like Kappa Andromeda. To date, more than 800 planets discovered outside our solar system, but scientists have been able to photograph a few of them.

A supernova explosion effect weighing 100 Earth masses radioactive titanium

According to scientists, a single supernova explosion in the surrounding area can be radioactive titanium, the total weight of which can exceed 100 times the mass of our planet.

These new data, to dispose of the radioactive substance during a supernova explosion, it may give an explanation of the mysterious processes occurring inside stars just before they are followed by a catastrophic explosion and the release of elements from which the universe is almost everything, from the stars and planets and ending human .

Nuclear NASA telescopes can see gravitational waves

This advanced technology is developed in the field of measurement, at the atomic level, the degree of change in ambient gravity , as well as for the detection of gravitational waves - ripples sort of space-time, which is caused by various events, including the Big Bang. According to the general theory of relativity, Albert Einstein created; gravitational waves are provided when massive cosmic bodies, during its motion, break the fabric of space and time. 

Irregular galaxies tend to become disks

​​Through the use of Hubble and Keck telescopes, astronomers have come to a rather startling conclusion about the nature, which is the process of change in the "blue" galaxies. Specifically, it relates to a process of change that takes place in these galaxies has for now as eight billion years - in other words, for the period, which is more than half the age of the universe.

Until now, it was assumed that the disk-shaped galaxy with a classic for these galaxies form, appeared in the universe, in its present form, about 8 billion years ago, and only slightly changed in all that time.

Curiosity made a great discovery?

Team Mission Mars Science Laboratory implied that they have some important news that they will be ready to share soon. But, like all serious scientists, they are awaiting confirmation of their results before say something specific. In an interview with the American radio station National Public Radio (NPR) science mission chief John Graettinger said that a sample of Martian soil, studied recently with the tool SAM (Sample Analysis at Mars) rover Curiosity, showed something "stunning ('earthshaking').

Distant star ingest a planet the size of Jupiter

Sized planet about 1.4 times larger than Jupiter is captivated by its own star for a solid veil of gas, according to new observations made ​​space telescope "Hubble".

The planet WASP-b is a gas giant, spinning dangerously close to its parent star so that its evaporation created a dense cloud of gas that does not pass light. 

Failed Flash explain the origin of dim supernova

A powerful supercomputer showed that the type of unusually faded stellar explosion can be recognized, in all probability, to the failed attempt to blow up a white dwarf.

A team of scientists led by George Jordan, researchers at Flash Center for Computational Science, University of Chicago, compared the unusually dim supernova type 1a supernovae with the normal of the same type. 

Mars and Earth were shaped from the same structure blocks

A team of Carnegie investigated hydrogen liquefy in water from the Martian subsurface, and found that Mars was formed from the same structure blocks as the Earth, and the changes in the chemical composition of the planet began to occur in the course of its subsequent evolution. This indicates that the terrestrial planets, including Earth, the same source of water - chondritic meteorites. However, unlike our planet, Mars rocks, which contain volatile components such as water, can be processed deep in the bowels of the planet.

Curiosity found on Mars, radiation is not dangerous for humans

Radiation levels on the surface of the Red Planet is equivalent to environment radiation in low Earth orbit, NASA discovered Martian rover Curiosity.

The first measurements of radiation levels - the first held on the surface of another planet - can cheer those who want to see how once on Mars for the first time set foot on the person: Curiosity rover found that people may well spend some time on the surface of the Red Planet.

supernova nuclear blasts produce a paste

When dying stars detonate as supernovae, spread out a shock wave lead the so-called "rebound" - matter and elementary particles are compressed towards the center of the star to achieve the density that come into play in the nuclear force.

In the development of a supernova nuclear particles can create different and often bizarre forms, such as rods, plates or vials and long threads - which gave the name to this phenomenon, associated with the famous Italian pasta. Creating a "paste" because in the dying star DIURNAL two types of forces - the Coulomb revulsion of the same charges and nuclear forces of attraction.

Meteorites found on Mars there is warm water

Hydrothermal cracks around Martian impact craters could be suitable places for living organisms, according to scientists.

The new study, manner 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.

A new "border" of the galaxy

Thanks to the telescope "Hubble" discovered galaxy, at a distance of 13.3 billion light years from Earth.

Scientists working with the space telescope "Hubble" and "Spitzer" discovered galaxy, which would be a record for the distance from the Earth.

Scientists have found a way to cool down the black hole

Samuel Grall and Alexander Le Tick the University of Maryland simulated a scenario in which the orbit of the black hole is placed satellite circling it with the same speed with which rotates itself a hole - so that the two objects remain fixed relative to each other.

Thus, they reproduce the conditions under which for those in the motion of the black holes can test the hypothesis made earlier by Stephen Hawking to the contingent of static black holes.

The development team Google Data Arts has released a new, experimental application for the browser Chrome, offers a virtual tour of our local stellar neighborhood.

The close pair of stars surrounded by a "mysterious dust"

Astronomers have discovered a curious disk of gas and dust surrounding a system of two stars, the origin of which scientists cannot explain the basis of the standard models of planetary evolution.

A binary star system (with a simple name of SDSS J0303 +0054) is composed of white and red dwarfs, separated by distance of about 700,000 kilometers, the distance between the two stars is a very small value. 

Telescope "Kepler" has completed the basic mission

Space telescope, "Kepler", designed to search for planets outside the solar system, has completed the major part of their mission, but will continue for another four years. The announcement was published on the website NASA.

For three and a half years of the Space Telescope, scientists were able to detect more than two thousand objects candidates for the title of exoplanets. 

Found near the Orion Nebula star cluster

Star cluster, which had previously been measured part of the spectacular Orion Nebula, is actually a separate creature, located in front of the nebula, according to a new study.

Scientists are using the Canada-French-Hawaii Telescope, located in Hawaii, discovered that the star cluster NGC 1980 is a separate group of massive stars in front of the Orion Nebula, which lies at a distance of about 1,500 light-years away and is one of the closest Earth "stellar nurseries". Accumulation unevenly scattered around the star iota Orion, located in the southern part of the "sword" of the constellation Orion.

Scientists have explained the preference of exoplanets

Since the planets in the solar system formed from the same cloud of gas and dust that the star itself, until recently, it was thought that the plane of their orbits must coincide with the plane of rotation of the star. However, beginning in 2008, astronomers began to find more and more exoplanets, which were in highly inclined orbits and even reverse (counter-rotating) with respect to its star.
