Cracks of water on this moon of Saturn?

underground oceans breathe through the cracks tiger of Saturn's moon Enceladus?

is known that large accidents dubbed tiger stripes throw ice into space from the frozen interior of the moon, creating a cloud of fine ice particles over the south pole of Enceladus, creating a mysterious Saturn ring called E. Ring

Recent evidence of this has come from the Cassini spacecraft, now orbiting Saturn.

Enceladus Pictured above we see a high resolution image when the probe as overhead.

The peculiar surface features mimicking double tiger stripes are visible in blue false.

Why Enceladus is active remains a mystery, as the neighboring moon Mimas, approximately the same size, seems quite inert.

An analysis of more recent dust captured by the Cassini spacecraft found evidence soda as you would expect from a salty ocean.

In contrast, some recent observations from Earth of ice ejected by Enceladus in Saturn's E ring show no evidence of the expected sodium.

This research is particularly interesting because the ocean could be a nominee to contain life.

NGC 604, a stellar nursery seen through X-rays

About 3 million light-years away in the vicinity of the spiral galaxy M33, the vast stellar nursery NGC 604 has about 1,300 light-years across, about 100 times the size of the Orion Nebula.

The blue areas of the image are hot gas. In fact, among the regions of star formation in the Local Group of galaxies, NGC 604 is the second largest after 30 Doradus, also known as the Tarantula Nebula in the Large Magellanic Cloud.

This color composite X-ray data (in blue) from the Chandra Observatory and Hubble optical data, we show that the bubbles cavernous NGC 604 and its cavities are filled with tenuous hot gas emission X-ray

is fascinating as well as such that NGC 604 is divided by a wall of gas relatively frío.Al west side (right) of the nebula, the data tell us that the material is heated to X-ray strong winds from a cluster of about 200 young, massive stars.

the east side filled cavities appear to be more X-rays old, suggesting that supernova explosions in the end of the evolution of a massive star, have contributed to its formation.

Found earthquakes on the surface of massive stars

Valencia

Astronomers have detected photometric images provided by the Corot satellite motion in the area of \u200b\u200bmassive stars, those that are much larger than the sun and rotation quickly, which will improve the knowledge of the internal structure of the major stars of the Universe.

analysis of CoRoT data is done using mathematical and sophisticated computer, some of which have been developed at the Astronomical Observatory of the University of Valencia.

The results of this research was presented this week CoRoT Congress 2009, held in Paris, the international meeting on the CoRoT mission organized after the satellite launch, December 2006.

Scientists can not access the interior of stars, only have the ability to observe its surface. Therefore, to deepen the knowledge of the structure of stars, the astronomers analyzed the so-called beats, which, like earthquakes on Earth is the only way to get to know more details of its inner part. The stars may change size and shape.

The existence of methane shows that Mars is a living planet

The existence of the gas, which is a key to life as known on Earth, was released today by a report in Science magazine published an issue dedicated to the World Year of astronomy.

spectrometers NASA telescopes in Hawaii detected at least three trails of methane on the surface of the planet.

"The atmosphere of Mars quickly destroys methane in various ways. Therefore, our discovery of methane in the hemisphere north in 2003 indicates that there is a flotation gas, "said Michael Mumma, Space Flight Center of NASA in Maryland.

" A mid-summer in the Northern Hemisphere methane is released at a rate comparable to after percolation at a site in California, "said Mumma, one of the authors of the report published by Science.

Methane, whose molecule consists of a carbon atom attached to four hydrogen atoms (CH4) is the main component of natural gas on Earth. also involved in other geological processes such as oxidation of iron.

Moreover, many living organisms on Earth emit gas during the process gas digestion of nutrients.

"Right now we do not have enough information to ensure that the methane on Mars is the product of biological or geological processes," said the scientist.

However, the mere existence of methane "tells us that the planet is still alive, at least in the geological sense," he added.

"We see multiple trails on Mars, one of which released about 19,000 metric tons of methane," said Geronimo Villanueva, a scientist at the Catholic University in Washington.

"These trails were issued during the warm seasons, spring and summer perhaps through the cracks that occurred in the ice, "he added.

Scientists have speculated that if there is a biological process this would be happening under the surface of Mars, where water is frozen and could not find samples of carbon.

"On Earth, microorganisms multiply to between 2,000 and 3,500 meters deep, where the radioactivity between water molecules," he said.

A water molecule consists of two oxygen atoms and one hydrogen atom (H20 ).

Mumma said that these microorganisms are supplied with power from hydrogen, a process that would be used by similar bodies to survive billions of years under the frozen surface of Mars.

gases such as methane would be released through the deep fissures that connect the land with the atmosphere, especially during the spring, said the scientist.
