NASA’s ‘Destination Station’ Coming To Atlanta

The public is invited to learn more about living in space, directly from NASA experts and space-exploring astronauts, in a series of special events coming to Georgia. The agency’s “Destination Station” activities in the Atlanta area start Monday, April 15.

SpaceX Dragon Spacecraft Carrying NASA Cargo Ready for Return to Earth

More than three weeks after arriving at the International Space Station, the Space Exploration Technologies Corp. (SpaceX) Dragon spacecraft is ready for the trip back to Earth, now scheduled for Tuesday, March 26.

NASA Extends Hubble Space Telescope Science Operations Contract

NASA is extending its contract with the Association of Universities for Research in Astronomy for the agency’s Hubble Space Telescope Science Operations activities at the Space Telescope Science Institute in Baltimore, Md., for 36 months.

NASA Awards Contract Modification for Support at Michoud Assembly Facility

NASA has signed a one-year contract option with Jacobs Technology, Inc., of New Orleans to continue manufacturing support and facilities operations at the agency's Michoud Assembly Facility in New Orleans.

Quantum computers coming soon? Metamaterials used to observe giant photonic spin Hall effect

Engineering a unique metamaterial of gold nanoantennas, researchers were able to obtain the strongest signal yet of the photonic spin Hall effect, an optical phenomenon of quantum mechanics that could play a prominent role in the future of computing.

Observations of early universe hint at a giant excess of anti-neutrinos

(Phys.org) —Scientists have a great deal of evidence to support the fact that the universe contains much more baryonic matter than baryonic anti-matter, a phenomenon known as baryon asymmetry. Baryons, which are defined as being made of three quarks, include protons and neutrons and make up the bulk of the atomic matter that we're familiar with in everyday life. But much less is known about the possibility of a lepton asymmetry, in which there are unequal amounts of leptons and anti-leptons in the universe. The best known examples of leptons are electrons and neutrinos.

Quantum computers counting on carbon nanotubes

Carbon nanotubes can be used as quantum bits for quantum computers. A study by physicists has shown how nanotubes can store information in the form of vibrations. Up to now, researchers have experimented primarily with electrically charged particles. Because nanomechanical devices are not charged, they are much less sensitive to electrical interference.

Planck's New Recipe of the Universe: More Matter, Less Dark Energy

Today NASA released a new map of the universe, and described it with a slew of superlatives: It is the "most accurate," "most detailed," "best map ever." It's that good.

Based on the first 15 months of data from the Planck mission's all-sky observations, this new map shakes up scientists' understanding of the standard model of cosmology, including how old the universe is, what it's made of, and how it came to be.

The data suggests that the universe's age ticker is currently at 13.8 bil

A revolutionary 'nuclear battery' a step closer

(Phys.org) —Experts in nuclear physics at the University of Surrey have helped develop research towards a 'nuclear battery', which could revolutionize the concept of portable power by packing in up to a million times more energy compared to a conventional battery.

NASA Hosts Its First Google+ Hangout in Spanish

NASA is expanding its reach to the nation's growing Spanish-speaking population by holding its first-ever Google+ Hangout en Espanol from 6:30 - 7:30 p.m. EDT, Thursday, March 28.
