NASA's Spitzer Space Telescope has at last found buckyballs in space, as illustrated by this artist's conception.
Astronomers using NASA's Spitzer Space Telescope have discovered carbon molecules, known as "buckyballs," in space for the first time. Buckyballs are soccer-ball-shaped molecules that were first observed in a laboratory 25 years ago.

They are named for their resemblance to architect Buckminster Fuller's geodesic domes, which have interlocking circles on the surface of a partial sphere. Buckyballs were thought to float around in space, but had escaped detection until now.

"We found what are now the largest molecules known to exist in space," said astronomer Jan Cami of the University of Western Ontario, Canada, and the SETI Institute in Mountain View, Calif. "We are particularly excited because they have unique properties that make them important players for all sorts of physical and chemical processes going on in space." Cami has authored a paper about the discovery that will appear online Thursday in the journal Science.

Buckyballs are made of 60 carbon atoms arranged in three-dimensional, spherical structures. Their alternating patterns of hexagons and pentagons match a typical black-and-white soccer ball. The research team also found the more elongated relative of buckyballs, known as C70, for the first time in space. These molecules consist of 70 carbon atoms and are shaped more like an oval rugby ball. Both types of molecules belong to a class known officially as buckminsterfullerenes, or fullerenes.

Using a combination of instruments on ESO's Very Large Telescope, astronomers have discovered the most massive stars to date, some weighing at birth more than 300 times the mass of the Sun, or twice as much as the currently accepted limit of 150 solar masses. This artist's impression shows the relative sizes of young stars, from the smallest "red dwarfs", weighing in at about 0.1 solar masses, through low mass "yellow dwarfs" such as the Sun, to massive "blue dwarf" stars weighing eight times more than the Sun, as well as the 300 solar mass star named R136a1.
Using a combination of instruments on ESO's Very Large Telescope, a UK-led international team of astronomers have discovered the most massive stars to date, one which at birth had more than 300 times the mass of the Sun, twice as much as the currently accepted limit.

The existence of these monsters - millions of times more luminous than the Sun, losing mass through very powerful winds - may provide an answer to the question "how massive can stars be?" The new results appear in a paper in the journal Monthly Notices of the Royal Astronomical Society.

A team of astronomers led by Paul Crowther, Professor of Astrophysics at the University of Sheffield, used ESO's Very Large Telescope, as well as archival data from the NASA/ESA Hubble Space Telescope, to study two young clusters of stars, NGC 3603 and RMC 136a in detail. NGC 3603 is a cosmic factory where stars form frantically from the nebula's extended clouds of gas and dust, located 22,000 light-years away from the Sun (eso1005).

RMC 136a (more often nicknamed R136) is another cluster of young, massive and hot stars, which is located inside the Tarantula Nebula, in one of our neighboring galaxies, the Large Magellanic Cloud, 165,000 light-years away (eso0613).

ET could be contacting us by cosmic Twitter
Aliens may have been trying to contact us by communicating in a manner similar to Twitter, scientists have claimed.

ET is more likely to be sending out short, directed messages than continuous signals beamed in all directions, experts said.

''This approach is more like Twitter and less like War and Peace,'' said Californian physicist Dr James Benford, president of Microwave Sciences Inc.

He and twin brother Gregory, an astrophysicist at the University of California, Irvine, looked at the Search for Extraterrestrial Intelligence (Seti) from the aliens' point of view.

They concluded that Seti scientists may have been taking the wrong approach for the past five decades.

Simon Bolivar, the 19th Century political leader
Hugo Chavez, the president of Venezuela, has exhumed the remains of South American independence hero Simon Bolivar to determine the cause of his death nearly 200 years ago.

Mr Chavez suspects that Bolivar was murdered and did not die from tuberculosis, as most historians believe.

Announcing the exhumation of his hero on Twitter, Mr Chavez said he "wept with emotion".

"What impressive moments we have lived tonight. We have seen the bones of the Great Bolivar!" he wrote.

"That glorious skeleton must be Bolivar, because his flame can be felt. Bolivar lives!" he added.

New Zealand Museum Thaws 100-Year-Old Whisky

The crates of Mackinlay's whisky found in an Antarctic hut
A crate of Scotch whisky that has been frozen in Antarctic ice for more than a century is being slowly thawed by New Zealand museum officials.

The crate of whisky was recovered earlier this year - along with four other crates containing whisky and brandy - beneath the floor of a hut built by British explorer Sir Ernest Shackleton during his 1908 Antarctic expedition.

Four of the crates were left in the ice, but one labelled Mackinlay's whisky was brought to the Canterbury Museum in Christchurch on New Zealand's South Island, where officials said it was being thawed in a controlled environment.

Nigel Watson, executive director of the New Zealand Antarctic Heritage Trust, said the whisky might still be liquid.

"When the guys were lifting it, they reported the sound of sloshing and there was a smell of whisky in the freezer, so it is all boding pretty well," he said.

Raptor over Blighty: Watch the stealth fighter in infrared

Farnborough

This week the Reg flying car, killer robot and general military crazytech desk has been attending the Farnborough Airshow. One of the show's highlights this year is the reappearance of the US F-22 Raptor ultrafighter, previously seen publicly in the UK for just one brief Monday display at Farnborough '08.

Hard landing
They move too fast for human eyes to see, but a camera has tracked individual sand particles spraying from an impact site in the first moments of crater formation.

Such movies could help us piece together the objects that created the craters which pock the surfaces of the moon and other celestial bodies. They could also help to predict the effects of impacts - to determine the risk flying debris poses to astronauts, for example.

Fast ejection

The resulting craters form in 100 milliseconds or less. By using high-speed video cameras that can capture up to 15,000 frames per second, the team could track individual sand particles as they were ejected from the impact.

Most of the material thrown up by the impact took to the air during the impact's "main stage", landing within a few crater radii of where the projectile hit. But the high-speed video also revealed particles kicked up in a relatively unstudied early stage.

During this phase of crater formation material is flung fastest and farthest, for example creating the long rays of the moon's Tycho crater and, potentially, launching a number of meteoroids into space from the surface of the moon and Mars.

Peruvian researchers uncovered bones of a tribal leader and a child that date back more than 1,200 years.

Peruvian archaeologists have found remains from a person believed to be a leader of a key pre-Inca civilization that is more than 1,200 years old, one of the researchers said.

Carlos Elera told AFP the remains from the northern region of Lambayeque are from what some call the Sican culture that flourished in the area between around 700 and 1375 AD.

He said among the remains found two weeks ago in the archaeological complex Las Ventanas is a type of sarcophagus for an adult with a headdress and a feathered eye mask, which are "characteristic of the nobles of the Sican culture."

The researcher also said that objects found included a ceremonial knife, ceramics, textiles with copper plates.

The excavation at Calne
Archaeology enthusiasts baffled by the mystery of Calne's castle have found evidence that a fortified building probably existed between the 13th and 17th centuries.

There are 29 current or disused place names containing the word castle, which suggests there was a building, motte and bailey or hill fort of some importance at the site, and motivated by the chance to solve this riddle, the Calne Castle Project was set up.

A two-week excavation at Castle Hill led by a volunteer group from the Wiltshire Archaeological and Natural History Society (WANHS), coincided with the British Archaeology Festival.

Society member Wendy Smith said: "The point of this exercise was to find out whether or not there was a castle in Calne and we have found pretty conclusive evidence that there was a castle.
