Physics and Astronomy

This area deals with the fundamental laws and building blocks of nature and how they interact, the properties and the behavior of matter, and research into space and time and their structures.

innovations-report provides in-depth reports and articles on subjects such as astrophysics, laser technologies, nuclear, quantum, particle and solid-state physics, nanotechnologies, planetary research and findings (Mars, Venus) and developments related to the Hubble Telescope.

UAB Scientists break the hard drive miniaturisation limit

Magnetic memory-based information storage systems are getting smaller and smaller, while their capacities are getting larger. However, there is a limit to how small they can get. If the tiny magnets used to store information are smaller than around five nanometres (millionths of a millimetre), vibrations caused by temperature can erase their orientation and, therefore, the information they contain. This is known as the superparamagnetic limit, which physically limits the capacity of magnetic storage

Revolutionary tungsten photonic crystal could provide more power for electrical devices

Energy emissions far greater than predicted by Planck’s Law

You can’t get something for nothing, physicists say, but sometimes a radical innovation can come close.

Researchers at Sandia National Laboratories — exceeding the predictions of a 100-year-old law of physics — have shown that filaments fabricated of tungsten lattices emit remarkably more energy than solid tungsten filaments in certain bands of near-infrared wavelengths when heated.

UCI study finds dark matter is for superWIMPs

New class of superweak particles may reveal secrets of hidden mass in universe

A UC Irvine study has revealed a new class of cosmic particles that may shed light on the composition of dark matter in the universe.

These particles, called superweakly interacting massive particles, or superWIMPs, may constitute the invisible matter that makes up as much as one-quarter of the universe’s mass.

UCI physicists Jonathan Feng, Arvind Rajaraman and Fumihiro Takayama report th

Newly Launched ’Opportunity’ Follows Mars-Bound ’Spirit’

NASA launched its second Mars Exploration Rover, Opportunity, late Monday night aboard a Delta II launch vehicle whose bright glare briefly illuminated Florida Space Coast beaches.

Opportunity’s dash to Mars began with liftoff at 11:18:15 p.m. Eastern Daylight Time (8:18:15 p.m. Pacific Daylight Time) from Cape Canaveral Air Force Station, Fla.

The spacecraft separated successfully from the Delta’s third stage 83 minutes later, after it had been boosted out of Earth orbit

Astronomers find ’home from home’ – 90 light years away

Astronomers looking for planetary systems that resemble our own solar system have found the most similar formation so far. British astronomers, working with Australian and American colleagues, have discovered a planet like Jupiter in orbit round a nearby star that is very like our own Sun. Among the hundred found so far, this system is the one most similar to our Solar System. The planet’’s orbit is like that of Jupiter in our own Solar System, especially as it is nearly circular and there

JLab’s CLAS physicists learn a little more about ‘nothing,’ get thrown for a spin

Daniel S. Carman (Ohio University) and nearly 150 members of Jefferson Lab’s CLAS Collaboration studied the spin transfer from a polarized electron beam to a produced Lambda particle. Their results were recently published in Physical Review Letters.

Measurements taken using Jefferson Lab’s CEBAF Large Acceptance Spectrometer (CLAS) are telling us more about how matter is produced from “nothing,” that is, the vacuum.
