    All the organic material extracted from the corpse has therefore now been identified and is conserved in responsible hands,’ a spokesman for the museum said. ‘On the basis of considerable historical documentation, there are no doubts about the authenticity of the items.’ The relics will be exhibited from early 2010, when the museum will re-open after current renovation work and will change its name to the Galileo museum. SNIP Clerics eventually denounced him to the Roman Inquisition in 1615 over his support of a heliocentric, or Sun-centered, view of the universe. Although he was cleared of any offence at that...
  • Sophisticated hunters not to blame for driving mammoths to extinction

    The animals, which included mammoths, elephant-sized mastodons and beavers the size of black bears, were probably picked off by more inept hunters who only much later developed specialised weapons when their prize catches became scarce. "Some people thought humans arrived and decimated the populations of these animals in a few hundred years, but what we've found is not consistent with that rapid 'blitzkrieg' overkill of large animals," said Jacquelyn Gill, a PhD student at the University of Wisconsin, Madison, who led the research team... Gill's team rules this out by putting a more accurate date on the decline and fall...

    Two fingers and a tooth removed from Galileo Galilei's corpse in a Florentine basilica in the 18th century and given up for lost have been found again, a Florence museum said Friday. Paolo Galluzzi, director of the Museum of the History of Science, said three fingers, a vertebra and a tooth were removed by enthusiastic admirers from the astronomer's body in 1737, 95 years after his death, while his corpse was being moved from a storage place to a monumental tomb, opposite the tomb of Michelangelo, in Santa Croce Basilica in Florence. One of the fingers was recovered soon after,...

    A radiation-resistant version of NRAM carbon-nanotube-based memory, developed jointly by Lockheed Martin and Nantero, was tested on a recent Space Shuttle mission. The NRAM was incorporated by NASA into special autonomous testing configurations installed into a carrier at the aft end of the payload bay. It was launched into space as part of STS-125, the May 2009 mission of the Space Shuttle Atlantis that successfully serviced the Hubble Space Telescope. The project was managed by Dan Powell, Chief Nanotechnologist at NASA Goddard Space Flight Center (GSFC).

    President Dmitry Medvedev says Russia will prioritize the development of nuclear energy, especially the use of nuclear technology in spacecraft. Medvedev made the announcement Thursday during his annual address to the Federal Assembly. This was not the first time that Russia has suggested the development of nuclear-powered spacecraft. Anatoly Perminov, the head of Federal Space Agency Roscosmos, said last month that the agency has planned to develop spacecraft with a megawatt-class nuclear power set.

    Dark energy isn't good for life in the universe. This mysterious substance, which cosmologists believe makes up around 70 percent of the universe, may eventually pull apart galaxies, then stars and planets, and finally atoms and molecules, in what some call the Big Rip. It’s ironic, then, that the search for dark energy might help in the search for life in the universe. That's because planet hunting through a technique called microlensing requires a similar sort of instrument as a dark energy mission.

    The Hubble Space Telescope (HST) is a space telescope that was carried into orbit by the Space Shuttle Discovery in April 1990. It is named after the American astronomer Edwin Hubble. Although not the first space telescope, the Hubble is one of the largest and most versatile, and is well-known as both a vital research tool and a public relations boon for astronomy. The HST is a collaboration between NASA and the European Space Agency, and is one of NASA’s Great Observatories, along with the Compton Gamma Ray Observatory, the Chandra X-ray Observatory, and the Spitzer Space Telescope.

    It's a solid doomsday prediction that in about 5 billion years the dying sun will expand as a bloated red giant and engulf the Earth. But imagine if in just a few weeks the middle-aged sun suddenly ballooned out to the orbit of Saturn and immediately vaporized Earth and most of the other planets in the solar system! And, even before this happened, imagine that every morning you awoke the sun was ever more sweltering until it began evaporating the oceans, spontaneously starting forests ablaze, and melting asphalt! This sounds like the stuff of a far-out science fiction movie. But...

    A new image of the bulge at the center of a distant spiral galaxy, taken by the Hubble Space Telescope, is giving astronomers insight into how these galactic paunches form. The image of NGC 4710 is part of a survey that astronomers have conducted to learn more about the formation of bulges, which are a substantial component of most spiral galaxies. When targeting spiral galaxy bulges, astronomers often seek edge-on galaxies, as their bulges are more easily distinguishable from the disc. The detailed edge-on view of NGC 4710, taken with Hubble's Advanced Camera for Surveys, shows the galaxy's bulge in...

    Sunlike stars that harbor planets are low on lithium, according to a recent study that may offer a new tool in the hunt for planets beyond our solar system. Stars are made almost entirely of hydrogen and helium. A small percentage of a star's mass comes from heavier elements, which astronomers refer to as metals. Young, yellow stars like our sun usually have more metals than older, redder stars, although the exact mix of those metals can vary. But astronomers have been unable to explain why otherwise similar sunlike stars have widely different lithium levels.The new study suggests that the...

Bech Nielsen of the Niels Bohr Institute in Copenhagen and Masao Ninomiya of the Yukawa Institute for Theoretical Physics in Kyoto, Japan, have published several papers over the past year arguing that the CERN experiment may be the latest in a series of physics research projects whose purposes are so unacceptable to the universe that they are doomed to fail, subverted by the...

The finding, which comes from analyzing stalagmites from Moaning Cavern in the central Sierra Nevada, was published online Nov. 5 in the journal Earth and Planetary Science Letters. The sometimes spectacular mineral formations in caves such as Moaning Cavern and Black Chasm build up over centuries as water drips from the cave roof.

But there are some years, like this one, where it's not possible to see sunspots clearly. When we're at this "solar minimum," very few, if any, sunspots are visible from Earth. That poses a problem for scientists in a new scientific field called "Space Weather," which studies the interaction between the sun and the Earth's environment....

To be built by IHI Aerospace, the ASR is Japan's proposed future launcher for medium scientific payloads. JAXA also is studying a further development that would cut costs partly by using a fuel that could be melted and formed into a solid engine at less than the boiling temperature of water. That follow-on rocket could be available for commercial use, according to ASR project leader Yasuhiro Morita.

    It would be fair to say that the crashy culmination of NASA's LCROSS mission on October 9th was a technical success but a public-relations fizzle. LCROSS on final approach LCROSS and its Centaur rocket prepare to crash into the Moon. NASA On the plus side, the engineering team for LCROSS (short for Lunar Crater Observation and Sensing Satellite) delivered as promised, deftly driving a spent 2½-ton Centaur rocket into a target zone near the Moon's south pole only 2 miles (3½ km) across. Four minutes later, after flying through the debris cloud raised by the rocket's crash, an instrument-packed 600-kg...

    What if the discrepancy arises from a flaw in our theory of gravity rather than from some provider of mass that we cannot see? In the 1980s physicist Mordehai Milgrom of the Weizmann Institute of Science in Rehovot, Israel, proposed a modification to Newtonian dynamics that would explain many of the observational discrepancies without requiring significant mass to be hidden away in dark matter. But it fell short of describing all celestial objects, and to incorporate the full span of gravitational interactions, a modification to Albert Einstein's theory of general relativity is needed. A review article in the November 6...

    "Now I am become Death, the destroyer of worlds." —The Bhagavad Gita Seven years after the nuclear tests in Alamogordo, New Mexico, Dr. J. Robert Oppenheimer, the father of the atomic bomb, was lecturing at a college when a student asked if there were any U.S. atomic tests before Alamogordo. “Yes, in modern times,” he replied. The sentence, enigmatic and incomprehensible at the time, was actually an allusion to ancient Hindu texts that describe an apocalyptic catastrophe that doesn’t correlate with volcanic eruptions or other known phenomena. Oppenheimer, who avidly studied ancient Sanskrit, was undoubtedly referring to a passage in...

    Back in 1980 the US space programme was in the doldrums. Apollo was fading into history and there hadn't been a US astronaut in space for five years. The quirky space shuttle, much diminished from its initial vision, was still waiting to make its maiden flight. But that fall came Cosmos, a revolutionary documentary series with a compelling host. Both the television universe and the real one have never been quite the same. Carl Sagan, by equal measure professorial and childlike, offered space enthusiasts a new paradigm. Buck Rogers was out; refined and groovy cosmic citizen was in. Here was...

    Scene 1: The White House Rose Garden. The President of the United States is standing before a crowd of amateur astronomers, students and teachers, with his science adviser by his side. In front of him: a telescope. The president bends down and presses his eye to the eyepiece. Flashbulbs pop. Scene 2: Kennedy Space Center. The Ares 1-X rocket sits on the launch pad, ready for its first test flight. More than 300-feet tall but fewer than 20 feet in diameter, it looks as precarious as a flying chopstick, but tomorrow's astronauts might ride a rocket like this one to...

    WASHINGTON (Reuters) - The U.S. military needs to deepen dialogue with China to better understand the intent of its space programs, a U.S. general said on Tuesday, after a Chinese commander announced plans to develop offensive military capabilities in space. General Kevin Chilton, head of the Pentagon's Strategic Command which coordinates U.S. military operations in space, said China-watchers had been "absolutely amazed" by the country's advances in its space programs over the past decade.

    Space explorers have yet to get their hands on the replicator of "Star Trek" to create anything they might require. But NASA has developed a technology that could enable lunar colonists to carry out on-site manufacturing on the moon, or allow future astronauts to create critical spare parts during the long trip to Mars.
