Why I Love Mercury Retrograde And Why You Could Too!

by Ines SuljMercury has just gone retrograde again. This time in Gemini, the sign it rules.All the planets, except Sun and Moon, go in apparent backward motion from time to time, yet the Mercury retrograde seems to be the most famous one. Almost everyone knows about it, including the people who know nothing about astrology and those who don’t even believe in it.In astrology, when a planet is in retrograde, it doesn’t actually move backwards in the sky. It only a [...]

Frustrated magnets showing features of Hall Effect stun Princeton University researchers


Frustrated-Magnets



Excerpt from worldtechtoday.com

A group of researchers at the Princeton University has found that frustrated magnets, inspite of not possessing any magnetic feature at low temperatures, do exhibit features of Hall Effect. ‘Frustrated’ magnets are so called because of their inability of getting a long range magnetic order inspite of a huge exchange between the spins of their elementary particles.

The Hall Effect suggests that when magnetic field is applied to electric current carried by charged particles present in a conductor, it causes magnet to bend to the other side of semi-conductor. They are of great interest in physics and material science. Appreciating that frustrated magnets are capable of producing Hall Effect could hold the key to future advances in computing and the creation of devices such as quantum computers.

“To talk about the Hall Effect for neutral particles is an oxymoron, a crazy idea,” said N. Phuan Ong, one of the authors of the study and Eugene Higgins Professor of Physics at Princeton.

Inspite of that, he together with his colleague, Princeton’s Russell Wellman Moore Professor of Chemistry as well as their graduate students Max Hirschberger and Jason Krizan witnessed this unusual behavior in frustrated magnets.

“All of us were very surprised because we work and play in the classical, non-quantum world. Quantum behavior can seem very strange, and this is one example where something that shouldn’t happen is in reality there. It really exists,” said Ong in a statement.
The researchers wanted to find out the reason underlying “discontent” nature of Hall Effect.

In this particular case, the team led by Ong and Moore studied pyrochlores, a class of magnets ‘which should have orderly “spins” at very low temperature, but have been found to have spins that point in random directions, thus rendering them with magnetic frustration properties.’ They attached small electrodes to both sides of crystals and later passed heat through them using microheaters at extremely low temperatures.

The outcome of the experiment, states Ong, stunned the entire team.

Dawn’s imagery of Ceres keeps getting better


These two views of Ceres were acquired by NASA's Dawn spacecraft on Feb. 12, 2015, from a distance of about 52,000 miles (83,000 kilometers) as the dwarf planet rotated. The images, which were taken about 10 hours apart, have been magnified from their original size. Credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA

Excerpt from spaceflightnow.com

Images from NASA’s Dawn spacecraft on approach to the dwarf planet Ceres show a world pockmarked by craters and mysterious bright spots, and scientists are eager for a better look in the weeks ahead.

The latest images were taken Feb. 12 at a distance of 52,000 miles, or 83,000 kilometers, from Ceres. NASA released the fresh views Tuesday.

Every picture taken of Ceres in the coming weeks will show greater detail, as Dawn is set to be captured by the Texas-sized world’s gravity March 6. The dwarf planet will pull Dawn into the first of a series of survey orbits 8,400 miles from Ceres around April 23.

The imagery so far reveals Ceres as a cratered world, and Dawn will make a global map of the dwarf planet during its time in orbit.
But several bright spots have captured the attention of scientists.
“As we slowly approach the stage, our eyes transfixed on Ceres and her planetary dance, we find she has beguiled us but left us none the wiser,” said Chris Russell, principal investigator of the Dawn mission, based at UCLA. “We expected to be surprised; we did not expect to be this puzzled.”

The suspense is compounded by Dawn’s slow rate of approach. The probe’s ion propulsion system is gradually nudging Dawn on a trajectory closer to Ceres, eventually moving the spacecraft close enough to be grasped by the 590-mile diameter dwarf planet’s gravity.

“I want to know what is causing the bright spots,” Russell wrote in an email to Spaceflight Now. “The increased resolution seems to have moved us no closer to answering this mystery. I am frustrated by the suspense. This is the one problem of ion propulsion: We are closing in on Ceres very slowly.”

The latest photos have a resolution have 4.9 miles, or 7.8 kilometers, per pixel, according to a NASA press release.

Dawn’s framing camera will take its next set of images Feb. 20 at a range of about 30,000 miles. After late February, the resolution of Dawn’s imagery will be reduced as the spacecraft passes Ceres and flies in front of it, before being pulled closer in early April for insertion into orbit.

Soon after arriving in April, the spacecraft’s instruments will look for the signature of water vapor plumes shooting into space from the surface of Ceres, which may be blanketed in a crust of ice.
Dawn will orbit closest to Ceres in December at an altitude of 232 miles.

Dawn’s mission planners say the spacecraft could operate around Ceres until late 2016.

Ceres is the second destination for NASA’s Dawn mission, which launched in September 2007 and visited asteroid Vesta in 2011 and 2012.
