Super-dense neutron stars and their secrets

Scientists have new clue to the strange operation of neutron stars - these objects are so dense that they compress the mass of several suns in the space of less than a terrestrial city.

Neutron stars are born when a massive star runs out of fuel for nuclear fusion and decay. They cast off its outer layers, and their nuclei are compressed by gravity and become denser and denser. 

The new telescope IRIS transmits the first data about the mysterious region of the Sun

The team plans to publish an article in Astrophysical Journal, which details made ​​the discovery and research based on the constant lookout for 10yu quasars. Researchers have documented enormous capacity for radiation from quasars, which reach for many thousands of light-years distant, even beyond their own galaxies.

Mayan Discovery: Ancient Monument Reveals Royal Struggle

A nearly 1,500-year-old Mayan stone monument, inscribed with a story of an ancient power struggle, has been unearthed in Guatemala.

The stone slab, which dates to A.D. 564, was found in a small tunnel that adjoins the tomb of an ancient queen beneath the Mayan temple at the site of El Peru-Waka'.

NASA wants to exceed the speed of light

Nobody is surprised that NASA wishes to exceed the speed of light, which to our knowledge is the fastest in the universe. Most potentially habitable planets found the U.S. space agency are several light years away, meaning that for many years we would need to travel at the speed of light to reach them. This is no doubt a problem, because currently we are not able to achieve even a tenth of the speed of light, although the agency supergeniuses already working on it.

Physicist Harold G. White hopes to use speed travel "warp" (or push warp ) to exceed the speed of light. 

Why does the universe have fewer dwarf galaxies which should?

Turn and shoot the Question: "What about the sun?". "He went to sleep," his mother answered thinking an explanation that satisfies the curiosity of his three years. "He night," says halfway between the statement and the question and question again looking at the sky: "What about the moon? In these sentences, little seems to sum up, with its childlike simplicity-the concerns, from primitive man to the present day, led mankind to observe the sky for answers to many questions.

Probe NASA image of Earth is 1.5 billion km

NASA released the first images of the Earth from untreated about 1.5 billion kilometers. The record was made by the Cassini spacecraft, orbiting Saturn, and will make part of a mosaic that shows the giant planet and our planet.

Mars suffered early loss of most of the atmosphere

When I was a young man with less than 500 million years ago, Mars suffered a catastrophe that hung its magnetic field, leave it exposed to strong solar winds and caused him to lose most of its atmosphere. This is the most plausible story for children on the planet, according to the latest findings of the rover Curiosity.

The conclusion is in two studies published today in the journal "Science" that reveal with unprecedented precision the composition of air on Mars.

A study warns that sea level may rise 20 meters by the end of the century

The ice of the Antarctic "is much more sensitive" to climate changes than estimated, according to a scientific study which says that sea level could rise 20 meters to the end of the century if this area, the West Antarctic and Greenland, were to melt as in the Pliocene.

These are two of the findings of an international study published in the journal Nature Geo science, led by researchers from Imperial College London and Spanish participation.

Chemically induced pluripotent stem cells

Scientists have been able to reprogram the mature human stem cells, using only the chemical compound (without genetic manipulation).

A new method of obtaining cells are as versatile as embryonic stem cells, reduces the risk of developing cancer or of mutations that can occur as a result of stem cell therapies, "reprogrammed" with the introduction of additional genes.

Since then, in 2006, it was announced the discovery of induced pluripotent stem cells ( iPSCs ), scientists have sought to reduce the number of additional genes required for such cells. But it is always required at least one encoding a protein Oct-4 .

Fourth domain for a new form of life

The famous anecdote "On board the space station discovered a giant virus that infected Soviet cosmonaut" may be not so absurd: Biologists have discovered a virus of such size that they have no right to believe in it.

Initially called it simply - NLF, a new form of life (New Life Form). Strange body, a dedicated French microbiologist from sea water samples, pick up off the coast of Chile, infects the simplest - amoebas. Soon, the same body showed up and in Australia.

Student Engineers Spark Zero-Gravity Fires on Weightless Wild Ride

Gravity, we have defied you. Seven university student teams from across the United States escaped the pull of Earth's gravity — if only for a few seconds — on a NASA microgravity flight to see how fire, liquids and magnets behave in weightlessness.

The students flew with NASA's Microgravity University Program Friday (July 19) aboard a Zero Gravity Corporation Boeing 727 jet modified to fly up and down on a parabolic path to create up to 30 seconds of zero gravity, moon gravity or Martian gravity on the downswing followed by periods of "hypergravity" (twice Earth's pull) on the way back up.

Curiosity Rover Samples Air for a Taste of Mars History

It’s time to update the list of ingredients in Martian air.

In late 2012 NASA’s Curiosity rover drew air into its onboard laboratory and analyzed Mars’s atmospheric composition with a pair of spectrometers. The results of the investigation, published July 19 in Science, revise decades-old data on the makeup of Red Planet air and paint a broad picture of how the atmosphere has changed since the planet’s formation.

Physicists unveil results helping explain the universe

After a quarter-century of searching, scientists have nailed down how one particularly rare subatomic particle decays into something else — a discovery that adds certainty to our thinking about how the universe began and keeps running.

The world's top particle physics lab said Friday it had measured the decay time of a particle known as a Bs (B sub s) meson into two other fundamental particles called muons, 

The planets orbiting cooler stars have a warm climate

There is an assumption that the planets orbiting the cold star may not be on the surface of snow or ice, in contrast to those that rotate around hot. This is possible due to the interaction of starlight with ice and snow on the surface of the planets.

NASA selected the advanced technological concepts for further development

NASA has selected 12 proposals, including two from the Jet Propulsion Laboratory in Pasadena (of California), for the study of the first phase of the Subsidiary Innovative Concepts (NIAC). The program focuses on a detailed study and elaboration of existing concepts without specific algorithm they use to humans. Thus, through this process, it is planned to make a series of scientific fantasies into reality.

Hubble telescope has found the impossible planet

Scientists are puzzled by the new discovery that could make using the space telescope Hubble. They found outside our solar system planet, the conditions of origin of which modern science can not yet explain. The report is published on the website of the Institute Space Telescope. Cosmic body surprising origin was discovered during monitoring situated at a distance of 176 light-years from Earth, the star TW Hydra. Heavenly body, which exoplanet, is removed from the star is 12 billion kilometers, reports the publication .

Suspended a spacewalk after finding fluid in the spacesuit

"The decision to suspend the walk, as European astronaut Luca appeared Parmitano water in diving," said Solovyov told Interfax.

The "fluid leakage" occurred when Parmitano and NASA astronaut Chris Cassidy performing repair and maintenance tasks outside the orbital outpost.

"After that the U.S. took the decision on the urgent return of the astronauts aboard the ISS," said Anna Vedisheva, spokesman for the Russian space agency Roscosmos.

Solving a mystery than 3,500 million years

Scientists cannot know for sure if there is life in space outside the Earth, but new research by a team of scientists led by an astrobiologist at the University of South Florida (USF) shows that one of the key elements that produced life on Earth was brought to Earth by meteorites.

In an article published in the Proceedings of the National Academies of Sciences, 

NASA Moon Probe Helps Pin Down Off-Planet Driving Record

A 1970s Soviet rover did indeed travel about 3 miles farther on the surface of the moon than originally thought, meaning that any robot hoping to break its off-world distance record will have to run a full marathon, researchers say.

The remote-controlled Lunokhod 2 moon rover was long thought to have traveled 23 miles (37 kilometers) on the lunar surface back in 1973. But a Russian team recently upped the estimate to 26 miles (42 kilometers), using images snapped by NASA's sharp-eyed Lunar Reconnaissance Orbiter.

5 scientific theories about what aliens might look like Jellyfish? Bugs? Or just like you?

We've seen them portrayed in a vast variety of Hollywood films, from the nasty, slimy suckers shown in Independence Day to the precious, teddy-bear-esque creature that charmed us in E.T. But which is closer to the truth? As our understanding of the universe grows and the outlook on our existence is in turn humbled, scientists are beginning to theorize what these extraterrestrials might look like. 

The Sombrero Galaxy is seen by the Hale

What happens in the center of this spiral galaxy? Call Sombrero Galaxy for its resemblance to the Mexican sombrero, M104 has a very striking dust lane and bright halo consisting of stars and clusters globular. 

The diffuse glow of the extended core of the galaxy is due to the brilliance of billions of old stars. 

Colorful imaged the death of a planetary nebula

The NASA has achieved through his telescope Chandra grasping the end of a star's life, namely NGC 2393, known as "Eskimo Nebula". This study allows astronomers to predict the demise of the Sun, expected within about 5,000 million years.

Planetary nebulae like this are formed when a star consumes all the hydrogen in its core, something will happen to our sun in about 5,000 million years, reports NASA. At the time this happens, 

The first exoplanet that around a solar-type star

That blue dot in the upper right is Gliese 504b (GJ 504b), a giant planet that is 59 light years from Earth orbiting a solar-type star. But what is this special? Have we not already seen several extrasolar planets directly? Yes, but doing a little cheating. And is that exoplanets we have seen directly, as the system HR 8799, for example-are actually training worlds still shine with their own light, especially in infrared. 

Discover the oldest lunar calendar in a field of Aberdeen shire

UK archaeologists have discovered the oldest lunar calendar, found so far, in a field of Aberdeen shire (Scotland). The yearbook is a series of 12 holes that appear to mimic the phases of the moon and the lunar months and is believed chosen about 10,000 years old.

Excavations at the site began a decade ago and the first hole was discovered in 2004.
