NASA Hubble Finds a True Blue Planet

Astronomers making visible-light observations with NASA's Hubble Space Telescope have deduced the actual color of a planet orbiting another star 63 light-years away.

NASA's Opals to Beam Data From Space Via Laser

NASA will use the International Space Station to test a new communications technology that could dramatically improve spacecraft communications, enhance commercial missions and strengthen transmission of scientific data.

Space Station Ocean Imager Available to More Scientists

The International Space Station is expanding the use of its Hyperspectral Imager for the Coastal Ocean (HICO) instrument to more Earth scientists and environmental researchers.

NASA Astronaut Tom Marshburn Discusses Spaceflight at Newseum During Live Spacewalk

NASA is inviting news media representatives to a discussion with astronaut Tom Marshburn from 8:00-9:30 a.m. EDT on Tuesday, July 16 at the Newseum in Washington.

CASL milestone validates reactor model using TVA data

Today, the Consortium for Advanced Simulation of Light Water Reactors (CASL) announced that its scientists have successfully completed the first full-scale simulation of an operating nuclear reactor. CASL is modeling nuclear reactors on supercomputers to help researchers better understand reactor performance with much higher reliability than previously available methods, with the goal of ultimately increasing power output, extending reactor life, and reducing waste.

The Possible Parallel Universe of Dark Matter

As researchers learn more about dark matter's complexities, it seems possible that our galaxy lives on top of a shadow galaxy without us even knowing it.

New phenomenon could lead to novel types of lasers and sensors

There are several ways to "trap" a beam of light—usually with mirrors, other reflective surfaces, or high-tech materials such as photonic crystals. But now researchers at MIT have discovered a new method to trap light that could find a wide variety of applications.

Putting more science into the art of making nanocrystals

Chemists are making the process of synthesizing quantum dots much more systematic. They are detailing an effective new method for purifying CdSe nanocrystals with well-defined surface properties.

Space station illuminates dusty plasmas for a wide range of research

One of the most frequently-used physics laboratories on the International Space Station recently completed its final set of experiments. The Plasma Kristall Experiment (PK-3 Plus) lab, a Russian-German cooperation in operation since January 2006, has provided new insight into an unusual type of matter called plasma crystals. Though the experiment runs came to a close on June 14, the research continues to open an exciting world of potential technological spin-offs in medicine, agriculture and general science.

A new way to trap light: Phenomenon could lead to new types of lasers and sensors

There are several ways to "trap" a beam of light -- usually with mirrors, other reflective surfaces, or high-tech materials such as photonic crystals. But now researchers have discovered a new method to trap light that could find a wide variety of applications.
