Awesome death spiral of a bizarre star

The name of this thing is AFGL 3068. It’s been known as a bright infrared source for some time, but images just showed it as a dot. This Hubble image using the Advanced Camera for Surveys reveals an intricate, delicate and exceedingly faint spiral pattern. It’s so faint no one has ever detected it before!

So what’s going on here? First off, this is not a spiral galaxy! It’s a binary star*, two stars that orbit each other, located about 3000 light years away from us. One of the stars is what’s called a carbon star, similar to the Sun but much older. The Sun is still happily fusing hydrogen into helium in its core, but older stars run out of available hydrogen. Eventually, they fuse helium into carbon. When this happens the star swells up and becomes a red giant (note: that’s the brief version; the actual events are a tad more complicated).

Mars rover Curiosity scoops, detects bright object


This image from the right Mast Camera (Mastcam) of NASA’s Mars rover Curiosity shows a scoop full of sand and dust lifted by the rover’s first use of the scoop on its robotic arm. In the foreground, near the bottom of the image, a bright object is visible on the ground. The object might be a piece of rover hardware. This image was taken during the mission’s 61st Martian day, or sol (Oct. 7, 2012), the same sol as the first scooping. After examining Sol 61 imaging, the rover team decided to refrain from using the arm on Sol 62 (Oct. 8). Instead, the rover was instructed to acquire additional imaging of the bright object, on Sol 62, to aid the team in assessing possible impact, if any, to sampling activities. For scale, the scoop is 1.8 inches (4.5 centimeters) wide, 2.8 inches (7 centimeters) long.

NASA Mars Rover Opportunity Reveals Geological Mystery: Spherical Objects Unlike Previously Found ‘Blueberries’

ScienceDaily (Sep. 14, 2012) — NASA’s long-lived rover Opportunity has returned an image of the Martian surface that is puzzling researchers.

Spherical objects concentrated at an outcrop Opportunity reached last week differ in several ways from iron-rich spherules nicknamed “blueberries” the rover found at its landing site in early 2004 and at many other locations to date.

Opportunity is investigating an outcrop called Kirkwood in the Cape York segment of the western rim of Endeavour Crater. The spheres measure as much as one-eighth of an inch (3 millimeters) in diameter. The analysis is still preliminary, but it indicates that these spheres do not have the high iron content of Martian blueberries.

“This is one of the most extraordinary pictures from the whole mission,” said Opportunity’s principal investigator, Steve Squyres of Cornell University in Ithaca, N.Y. “Kirkwood is chock full of a dense accumulation of these small spherical objects. Of course, we immediately thought of the blueberries, but this is something different. We never have seen such a dense accumulation of spherules in a rock outcrop on Mars.”

Chile May Soon Legalise Ayahuasca

September 12, 2012 Leave a comment

‘A few days ago a court in Chile ruled that ayahuasca is not a substance harmful to health. In contrast, this compound may be highly beneficial to the welfare of human beings. A mystery is revealed in this herb, as a vine metaphysical joins heaven and earth, the soul with the body and the conscious mind with the unconscious.

Make an ayahuasca ceremony may have cost him a couple seven years in prison. Luckily Cesar Ahumada Lira, 42, and her partner, Danae Dimitra Saenz, 41, were acquitted by the trial court IV Oral Criminal Santiago, Chile.

“The court came to the conviction that far from being a danger to public health, developed by the defendants conduct has brought important benefits to many people, several of whom recounted their experiences in Court,” the legal document released EFE.’

The unidentified object at the Bottom of the Baltic Sea Cuts off Electrical Equipment when Divers Get Within 200 Metres

‘The divers exploring a ‘UFO-shaped’ object at the bottom of the Baltic Sea say their equipment stops working when they approach within 200m.

Professional diver Stefan Hogerborn, part of the Ocean X team which is exploring the anomaly, said some of the team’s cameras and the team’s satellite phone would refuse to work when directly above the object, and would only work once they had sailed away.

He is quoted as saying: ‘Anything electric out there – and the satellite phone as well – stopped working when we were above the object.’

Nanotechnology Used to Harness Power of Fireflies


ScienceDaily (June 15, 2012) — What do fireflies, nanorods, and Christmas lights have in common? Someday, consumers may be able to purchase multicolor strings of light that don’t need electricity or batteries to glow. Scientists at Syracuse University found a new way to harness the natural light produced by fireflies (called bioluminescence) using nanoscience. Their breakthrough produces a system that is 20 to 30 times more efficient than those produced during previous experiments.

It’s all about the size and structure of the custom, quantum nanorods, which are produced in the laboratory by Mathew Maye, assistant professor of chemistry in SU’s College of Arts and Sciences; and Rebeka Alam, a chemistry Ph.D. candidate. Maye is also a member of the Syracuse Biomaterials Institute. “Firefly light is one of nature’s best examples of bioluminescence,” Maye says. “The light is extremely bright and efficient. We’ve found a new way to harness biology for non-biological applications by manipulating the interface between the biological and non-biological components.”

Their work, “Designing Quantum Rods for Optimized Energy Transfer with Firefly Luciferase Enzymes,” was published online May 23 in Nano Letters and is forthcoming in print. Collaborating on the research were Professor Bruce Branchini and Danielle Fontaine, both from Connecticut College.

Neutrons Escaping to a Parallel World?


ScienceDaily (June 15, 2012) — In a paper recently published in European Physical Journal (EPJ) C, researchers hypothesised the existence of mirror particles to explain the anomalous loss of neutrons observed experimentally. The existence of such mirror matter had been suggested in various scientific contexts some time ago, including the search for suitable dark matter candidates.

Theoretical physicists Zurab Berezhiani and Fabrizio Nesti from the University of l’Aquila, Italy, reanalysed the experimental data obtained by the research group of Anatoly Serebrov at the Institut Laue-Langevin, France. It showed that the loss rate of very slow free neutrons appeared to depend on the direction and strength of the magnetic field applied. This anomaly could not be explained by known physics.

Berezhiani believes it could be interpreted in the light of a hypothetical parallel world consisting of mirror particles. Each neutron would have the ability to transition into its invisible mirror twin, and back, oscillating from one world to the other. The probability of such a transition happening was predicted to be sensitive to the presence of magnetic fields, and could therefore be detected experimentally.
