A spacewalking astronaut accidentally let go of her tool bag after a grease gun inside it burst, and watched as the kit floated away.
Heidemarie Stefanyshyn-Piper and Stephen Bowen were taking part in the first of four spacewalks of the Space Shuttle Endeavour's current mission to the International Space Station.

The stats and speeds involved are mind-blowing.
The European Southern Observatory has released a photograph of deep space that shows clusters of stars so old that they're seen "as they were when the universe was only two billion years old".
The stars and galaxies are located in the U-band - the boundary between visible light and ultraviolet.
Due to the Earth's atmosphere, photos of objects of this distance are about the furthest that ground-based telescopes can take. [via]

Scientists have determined the mass of the largest things that could exist in our universe - 50 billion suns!
Based on this self-regulating maximum rate, scientists at the Harvard-Smithsonian Center for Astrophysics, Massachusetts, and the European Southern Observatory, Chile, have calculated an upper limit for these mega-mammoth masses. Fifty billion suns, that's 100 000 000 000 000 000 000 000 000 000 000 000 000 000 kg, otherwise known as "ridiculously stupidly big" and triple the size of the largest observed black hole, OJ 287.
Nine years after its discovery in the badlands of southeastern Alberta, Canada, a 75-million-year-old fossil of a pregnant turtle has finally made its public debut.
At 40 centimetres long, its turtle shape is still evident and most of its skeleton is complete but its shell is crushed. The pregnant fossil was found in 1999. Six years later, a fossilized nest of eggs was found from the same species about 50 kilometres away.
Both specimens belong to an extinct turtle called Adocus, a large river turtle that lived with the dinosaurs and resembles today's slider and cooter turtles.
"It is the first fossil of a pregnant turtle found in the world and it's only the second fossil of an animal found in the world that's pregnant," explained Darla Zelenitsky, a University of Calgary scientist whose expertise is fossil nest sites.

Popular Mechanics has obtained some exclusive photos of the B-2 Stealth Bomber that crashed in Guam back in February. It's amazing to think that there's over a billion dollars worth of plane sat smouldering on a runway.
This is one of the first images captured by NASA's Phoenix Mars Lander which landed on the red planet yesterday. It touched down in an arctic region called Vastitas Borealis, at 68 degrees north latitude, 234 degrees east longitude.
The flat landscape is strewn with tiny pebbles and shows polygonal cracking, a pattern seen widely in Martian high latitudes and also observed in permafrost terrains on Earth. The polygonal cracking is believed to have resulted from seasonal freezing and thawing of surface ice.
A 50-year-study nstudy of 2,000 people born minutes apart has proved what may people have thought for a long time - astrology is rubbish!
The babies were originally recruited as part of a medical study begun in London in 1958 into how the circumstances of birth can affect future health. More than 2,000 babies born in early March that year were registered and their development monitored at regular intervals.
Researchers looked at more than 100 different characteristics, including occupation, anxiety levels, marital status, aggressiveness, sociability, IQ levels and ability in art, sport, mathematics and reading - all of which astrologers claim can be gauged from birth charts.
The scientists failed to find any evidence of similarities between the "time twins", however. They reported in the current issue of the Journal of Consciousness Studies: "The test conditions could hardly have been more conducive to success . . . but the results are uniformly negative."
A 19-year-old woman who was appointed as a full-time faculty Professor at Konkuk University in Seoul, South Korea has been recognised as the world's youngest professor.
Alia Sabur was enrolled at a university at age 10 and played clarinet with a symphony orchestra at 11.
Sabur was three days shy of her 19th birthday in February when she became a professor at Konkuk University, in Seoul. The previous record was held by a student of physicist Isaac Newton, Colin Maclaurin, who set the mark in 1717.
"He's in every calculus textbook there is," she said. "When I found out about it, I thought, 'I can't replace him.' But it's been 300 years and someone had to replace him, so why not me?"
She will be doing some classroom instruction, but mostly will focus on research into developing nanotubes for use as cellular probes, which could help discover cures for diseases such as cancer, she said.
Down the road, she would like to develop a noninvasive blood-glucose meter for people with diabetes, she said. Her mother, Julia, and her father, Mark, both have diabetes.
Sabur said classroom teaching in Seoul will be challenging because she doesn't speak Korean. "I can speak math and music," she said.
The European Space Agency (ESA) has released a computer-generated picture that shows Earth surrounded by thousands and perhaps millions of pieces of space junk.
ESA says the number of objects in Earth's atmosphere has risen steadily increasing by 200 per year on average and that there are now 600 working satellites.
Collisions, explosions and lost or discarded material from space flights and rockets has resulted in the atmosphere resembling a junk yard with potentially millions of pieces of metal travelling in permanent orbit 20,000 miles above the Earth.

Japanese scientists and origami masters are hoping to launch a paper airplane from space and learn from its trip back to Earth.
Shinji Suzuki, a professor at Tokyo University's Department of Aeronautics and Astronautics, believes that a successful flight from space by an origami plane could have far-reaching implications for the design of re-entry vehicles or space probes for upper atmospheric exploration.
In a test outside Tokyo in early February, a prototype about 2.8 inches long and 2 inches wide survived Mach 7 speeds and broiling temperatures up to 446 degrees Fahrenheit in a hypersonic wind tunnel — conditions meant to approximate what the plane would face entering Earth's atmosphere.
Having survived the 12-second test with no major damage or burns, the tiny plane theoretically could get back to Earth because re-entry from outer space involves passing through several layers that last only a few seconds each, said Osamu Imamura, a scientist who works with Suzuki.
The Japan Aerospace Exploration Agency, or JAXA, accepted it Wednesday for three years of feasibility studies and promised up to $300,000 in funding per year.

Seven 100-million-year-old feathers have been found perfectly preserved in amber in western France.
The feathers have features of both feather-like fibers found with some two-legged dinosaurs known as theropods and of modern bird feathers and they could fill in a key gap in the puzzle of how dinosaurs gave rise to birds.
The find provides a clear example "of the passage between primitive filamentous down and a modern feather," said team member Didier Néraudeau of the University of Rennes in France.
The study team isn't sure yet whether the feathers belonged to a dino or a bird.
But fossil teeth from two dino families thought to have been feathered were excavated from rocks just above the layer that contained the amber, Perrichot said.
"It is entirely plausible that the feathers come from a dinosaur rather than from a bird," he said.

Astronomers have glimpsed what may be the farthest galaxy we've ever seen.
Images taken with the Hubble Space Telescope have revealed the galaxy at almost 13 billion light-years away, making it the strongest candidate for the most distant galaxy ever seen.
The young galaxy, called A1689-zD1, was born about 700 million years after the Big Bang that scientists think created the universe. For most of its early life, the universe languished in "dark ages" when matter in the expanding universe cooled and formed clouds of hydrogen. Eventually matter began to clump into stars and galaxies that radiated light, heating up the universe and clearing the fog.
Scientists think this newly discovered galaxy may have been one of the first to form and help end the dark ages. Link

Is this a long-lost relative of whales, dolphins and porpoises? Professor Hans Thewissen of the Department of Anatomy at Northeastern Ohio Universities College of Medicine in Ohio, US thinks so.
The 48 million-year-old deer-like animal, Indonyus, shares certain anatomical features.
The structures of its skull and ear are similar to those of early whales, and like other animals that spend a lot of time in water, it had thickened bones that provided ballast to keep its feet anchored in shallow water.
"We've found the closest extinct relative to whales and it is closer than any living relative

A dinosaur 'mummy' that is one of the most complete ever has revealed invaluable information about muscle mass and the look of its scales.
The fossilized duckbilled hadrosaur is so well preserved that scientists have been able to calculate it's muscle mass and discover it was much more muscular than previously thought.
The dinoasaur, a calculated 3.5tons and up to 40ft, might have even been able to outrun predators like the tyrannosaurus rex.
Study of the mummy - which is 65 to 67 million years old - reveals that it was quick and flexible and had skin with scales that might have been striped.
The fossil was found in 1999 in the US state of North Dakota and now is nicknamed “Dakota.”
While called a mummy, the dinosaur body is in fact fossilized into stone - meaning it comes with skin, ligaments, tendons and possibly some internal organs, researchers say.
It's unlikely that you'll be seeing one of these in a 'Jurassic Park' anytime soon as its extremely unlikely that the DNA will have been preserved. Link
Paleontologists have discovered a giant fossilised claw that once belonged to an 8 foot long sea scorpion. Discovered in Germany by University of Bristol scientists, the 390 mya scorpion is half a yard longer than previous estimates and the largest one ever to have evolved.
The discovery in 390-million-year-old rocks suggests that spiders, insects, crabs and similar creatures were far larger in the past than previously thought, said Simon Braddy, a University of Bristol paleontologist and one of the study's three authors.
"This is an amazing discovery," he said Tuesday.
"We have known for some time that the fossil record yields monster millipedes, super-sized scorpions, colossal cockroaches, and jumbo dragonflies. But we never realized until now just how big some of these ancient creepy-crawlies were," he said.
A Japanese moon probe has taken some stunning high-definition images of the Earth 'rising' and 'setting'.
The Kaguya spacecraft, also called Selene, has been orbiting 62 miles (100 kilometers) above the moon since Oct. 18.
The new Earth-rise image shows our blue world floating in the blackness of space. Released today, it is a still shot taken from video made by the craft's high-definition television (HDTV) for space.
A second image, taken from a different location in the lunar orbit, has been dubbed Earth-set. A related series of still images shows our planet setting beyond the lunar horizon.
In the Earth-set image, Earth appears upside-down; visible are Australia and Asia. A region near the moon's south pole is seen in the foreground.

Ten years ago today, NASA and the European Space Agency launched the Cassini-Huygens spacecraft from Cape Canaveral, Florida. It was the beginning of a 15-year mission to explore Saturn and its moons.
Seven years later in 2004, Cassini entered Saturn's orbit and began delivering stunning images of the planet and its moons.
In December 2004, Cassini jettisoned the Huygens probe, which arrived at Saturn's largest moon, Titan, 22 days later. After orbiting Titan, Huygens landed in January 2005, sending scientists the most-detailed images of Titan's surface.
Ever since, the probe has continued to deliver breathtaking images such as these.
Fossil hunter Dr Phil Manning poses next to what he believes is the first tyrannosaurus rex footprint ever discovered.
Dr Manning, from the University of Manchester, found the metre-square impression in Hells Creek, Montana — famed for relics of the seven-ton flesh-eater.

“The size suggests that it’s more likely to have been the latter.” Link
The image above was taken on October 24th, 1946 by a US-built V2 missile and was the first time Earth had been photographed from space. The missile was launched from the White Sands Missile Range and snapped a new frame every second and a half as the rocket-borne camera climbed straight up. It then fell back to Earth minutes later, slamming into the ground at 500 feet per second. The camera itself was smashed, but the film, protected in a steel cassette, was unharmed.
