Chroococcidiopsis, which was used in this study, is shown here living in a rock from the Negev Desert in Israel. The green line running across the top of the rock is a thin endolithic film formed by the organism. These microbes live just below the surface of the rock, protected from the Sun's UV radiation.

Physicists have come up with a way to explain how information could escape from a black hole, an idea that's been debated since the 1970s.

The remnant known as G1.9+0.3 (shown here) came from the most recent supernova in our galaxy. To determine the age of the stellar explosion, astronomers tracked how quickly the remnant was expanding, by comparing a radio image from 1985 (blue) to an X-ray image taken in 2007 (orange).

This diagram shows a comparison of the sizes and strangely elliptical shapes of the orbits of the pulsar J1903+0327 and its possible Sun-like companion star with the orbit of the Earth around the Sun. The sizes of the Sun and the possible companion star have been exaggerated by a factor of about 10, while that of the Earth has been exaggerated by a factor of about 1000. The pulsar, with its magnetic field and beams of radiation, is too large by a factor of about 100,000. Credit: Bill Saxton, NRAO/AUI/NSF

Life Found a Mile Below Terrestrial Seabed; Implications For Life on Mars

We all know how hard life can be, but spare a thought for the microbes recently discovered 1.6 kilometres (1 mile) below the seabed off the coast of Canada. The living conditions are cramped, the environment is a searing 100°C (212F), and yet these hardy cells appear to be thriving. In the midst of the historic landing of Phoenix in the arctic wastes of Mars yesterday, the interest in finding life on the Red Planet has, yet again, reached fever pitch. Although Phoenix isn't built to look for life, it is assessing the Martian surface water content for signs that it may (or may have been able to) support life. This new discovery of life so deep below the Earth's surface may set some new limits on just how extreme life can be on other planets…

Hubble Survey Finds Half of the Missing Matter

esocid sends along the news that scientists believe they have found about half the missing matter in the universe. The matter we can see is only about 1/8 of the total baryonic matter believed to exist (and only 1/200 the mass-energy of the visible universe). This missing matter is not to be confused with "dark matter," which is thought to be non-baryonic. The missing stuff has been found in the intergalactic medium that extends essentially throughout all of space, from just outside our galaxy to the most distant regions of space. "'We think we are seeing the strands of a web-like structure that forms the backbone of the universe,' Mike Shull of the University of Colorado explained. 'What we are confirming in detail is that intergalactic space, which intuitively might seem to be empty, is in fact the reservoir for most of the normal, bary

Why the LHC Won't Destroy the World

An anonymous reader writes "Most people are aware of the recent articles contending that the Large Hadron Collider at CERN might destroy the world. While most scientists have no such concerns, a recent preprint released to arxiv systematically dismantles the notion. The gist of the argument is this: Everything that will be created at the LHC is already being created by cosmic rays. If a black hole created by the LHC is interactive enough to destroy the world within the lifetime of the sun, similar black holes are already being created by cosmic rays. Such black holes would be stopped by dense cosmic objects (neutron stars and white dwarfs). A black hole stopped in one of these objects would eventually absorb it. We see sufficiently old neutron stars in the sky, thus any black hole that could be created at the LHC, even if it is stable, wo

How information escapes from a black hole

If a black hole eats a book, what happens to the information? The latest work from a team of physicists says that in the distant future, the black hole eventually spits out the book's full contents. Even a black hole can't destroy information.

Imminent Discovery of Life On Mars?

Life on Mars?Do you think there is life on Mars? Do you think Phoenix will find evidence of it? Now there's a blog that's trying to collect a snapshot of the opinions of scientists, amateurs, and everyday people. "Imminent Discovery" thinks Phoenix may find simple life. Finding this evidence will definitely become headlines… If it happens. Is it possible it might have originated from earth? Perhaps from space, like the famous Antarctica meteorite which was believed to contain evidence of life transported here from Mars?

What Do You Do If Someone Blows Up Your Satellite? Call a Space Lawyer

As space travel becomes routine and private enterprise gets a foothold in low Earth orbit, it is becoming clear that specialists in the field of space law are required. Until now, lawyers here on the surface have extended their knowledge into space, but there will be a time when terrestrial lawyers will need to be superseded by a space equivalent. For example space lawyers could wrangle who is accountable for the space debris left behind after a satellite gets shot down. What happens if a nation accidentally (or deliberately) destroys another nation's spy satellite? Does this cause retaliation with global consequences or can the dispute be easily settled in "Space Court" with the help of space lawyers? These are extreme examples, but space lawyers may eventually become a part of everyday life for manned excursions into the cosmos.

Artist's rendering of the light echo of a high-energy flash from a black hole. When a star is disrupted by a black hole in the nucleus of a galaxy, its debris is inevitably attracted and absorbed by the black hole. This sudden increase in the accretion rate causes an abrupt burst of ultraviolet and X-ray light because the gas from the disrupted star becomes very hot. As the high-energy radiation travels through the core of the galaxy it illuminates surrounding matter and so makes it possible to probe regions of the galaxy that would otherwise be unobservable.

Unheard of life history for a vertebrate

There is a newly discovered life history among the 28,300 species of known tetrapods, or four-legged animals with backbones. A chameleon from arid southwestern Madagascar spends up to three-quarters of its life in an egg. Even more unusual, life after hatching is a mere 4 to 5 months. No other known four-legged animal has such a rapid growth rate and such a short life span. The new research is reported in the current issue of Proceedings of the National Academy of Sciences.
