Stardust samples of comet particles might seem like a strange place to find a big component of the green sand found on some Hawaiian beaches, but there it was.
The spacecraft, which flew within 150 miles of the comet Wild 2 in January 2004, brought back samples that may provide new insights into the composition of comets and how they vary from one another, scientists said Monday.
Remarkably enough, we have found fire and ice," said Donald Brownlee, Stardust principal investigator and professor of astronomy at the University of Washington in Seattle. The returned samples show high-temperature materials from the coldest part of our solar system. "

News: The Black Hole Road Show Kicks Off in Denver
Article Source : NASA
Deep down, black holes are filled with the vibrant light of gas trapped inside.
Venturing into the black hole at the center of our galaxy, you'd have a good 20 seconds' worth of viewing time of the radiant wonderland all around you before being vaporized, as you ride on a waterfall of moving space plunging toward the black hole core faster than light itself.
Well, Einstein's math supports such a scenario. And a team of scientists and television producers has turned Einstein’s equations into a new planetarium show called Black Holes: The Other Side of Infinity.

News: Scientists Making Progress with Comet Samples
Article Source : NASA
Since the Sample Canister has been delivered to the Stardust cleanroom at Johnson Space Center on January 17, the Preliminary Examination Team along with JSC Curatorial staff have been making good progress toward processing the returned samples. The processing is ahead of planned schedule on several fronts.
"This exceeded all of our grandest expectations," said Dr. Donald Brownlee, Stardust principal investigator, during a press conference following the sample canister’s arrival in Houston.

Several large international expeditions set off for different parts of the world last year to find vestiges of legendary Atlantis, which is still considered the exciting mysteries in the history of human civilization.
According to the legend, the continent was flooded ten thousand years before Christ. Scientists still find ancient maps showing now-defunct islands and continents.

A tiny pre-human who lived more than 900,000 years ago in what is now Kenya may have been a "short experiment" in evolution that never quite made it, scientists said Thursday. The little skull clearly belongs to an adult and was found last summer at a site where much larger hominids classified as Homo erectus lived, Richard Potts of the Smithsonian Institution and his research colleagues reported.
He or she died on a volcanic ridge, perhaps mauled by a lion or other carnivore, Potts said. It is the smallest adult fossil found dating back to the time of Homo erectus, the species of pre-human that dominated between 500,000 and 1.7 million years ago, Potts’ team writes in Friday’s issue of the journal Science. Potts believes the fossil find shows that early humans lived in little groups that became separate and distinct for a while, and then came together every few thousand years or so, swapped genes and then parted ways again.

THE appearance of a UFO in the sky above Kingsgate Retail Park last week caused spooked drivers to bump their cars.
Several people reported seeing a huge silver object in the area as they drove past at around 8.45am last Wednesday.Drivers were so distracted by the bizarre sighting that at least two minor bumps were reported, as the attention of motorists wandered from the more mundane forms of transport before them on the road.
A local woman, who did not wish to be named, contacted the News to describe the experience of a friend who was driving towards the retail park at that time.She said: "My friend saw something hovering, which was silver in appearance and looked like the dishes you see on the side of television transmitters.
"It was huge, and it was pulsating - he wasn't the only one who saw it, as you couldn't have missed it."He saw it and just thought: 'Good God', and was really quite shaken by the whole thing.

We're putting a new Gallery in place, and seeing as how it's one of the biggest sections of the Portal, I'd like to get it right first time. Well, as near as dammit heh.
To that end, I've asked Whitetiger to co-ordinate with people here how they'd like to see it organised. It was left to me before and I got a bit carried away lol.
So would you all speak up as to how you'd like to see it set up.There's a poll about it, and links to have a look in the Forum (link below) so have a check, and see what you think.

Far-away Easter Island has become an exotic port-of-call for medical researchers. First, they discovered a drug made from its bacteria can help kidney transplant patients. Now a similar drug may be a kidney cancer fighter.
Ed Onley, 68, gets a blood test every week to monitor his treatment. Two years ago, he lost a kidney to cancer. Last year tests found it had spread to his lungs. He?s in a study for an experimental drug called CCI-779."I play golf" ,Ed said. "I live my normal life so I think it's going very well."
