Photon Sieves Prove to be Pivotal to NASA's Heliophysics Studies
GREENBELT, Md., Dec. 15, 2023 — A pair of precision-orbiting small satellites will attempt to capture the first views ever of small-scale features near the surface of the sun that scientists believe drive the heating and acceleration of solar wind. According to Doug Rabin, a heliophysicist at NASA’s Goddard Space Flight Center, photon sieves, a technology that can focus extreme-ultraviolet (EUV) light, are expected to be able to resolve features on the sun 10 to 50 times smaller than what can be seen today with
First Images from Inouye Solar Telescope Provide Detailed Look at Sun
KULA, Hawaii, Jan. 31, 2020 — The first images from the National Science Foundation’s (NSF) Inouye Solar Telescope show a close-up view of the sun’s surface, detailing a pattern of turbulent “boiling” plasma that covers the entire sun. The cell-like...
Multi-Conjugate Adaptive Optics Device Offers Widest Real-Time Views of the Sun
BIG BEAR, Calif., Jan. 11, 2017 — A groundbreaking new optical device has been developed to correct images of the Sun previously distorted by multiple layers of atmospheric turbulence. The device developed at the New Jersey Institute of Technology’s (NJIT) Big Bear Solar...
Celestial light switch reveals lunar ranging data
May 5, 2014 — When certain members of the universe play a linear game of hide-and-seek, humans pay attention: Many don special solar glasses; others stay up late to catch sight of a burnt-orange moon. Solar and lunar eclipses are sights to behold, appearing just...
Sunshield for NASA Telescope Ready for Manufacturing
REDONDO BEACH, Calif., Sept. 27, 2013 — The template layers of a tennis-court sized sunshield that will help protect the optics on NASA’s James Webb Space Telescope have been completed, marking the final step before the final flight sunshield will be manufactured. Project...
Camera Images Aurora Hyperspectrally
SVALBARD, Norway, Nov. 29, 2012 — The first-ever hyperspectral pictures of the aurora borealis, or northern lights, revealed a previously unknown atmospheric phenomenon.
CMOS X-Ray Sensors Sharpen Astronomical Imaging
Oct 1, 2011 — There still are many unanswered questions in high-energy astrophysics: What is happening in the universe to produce so much gamma-ray energy? What happens to the surrounding environment near solar flares? Some of the answers could come from studying...
QDs Help Make Solar Fuel a Reality
MANCHESTER, England, July 5, 2011 — A solar-nano device is being created with the hope that it can harness the energy of the sun and convert it into a clean fuel alternative. Using quantum dots grafted with catalyst molecules, scientists are harvesting the sun’s energy to...
Cellular and Stellar Images Win Awards
BELFAST, Northern Ireland, Nov. 16, 2010 — Two visually stunning and scientifically captivating entries have won joint first place in the first Andor Insight Awards Scientific Imaging Competition, Andor Technology plc has announced. The winning entries were submitted by David Jess and...
Frog’s foam fashions fuel
Jun 7, 2010 — With the inevitable decline of fossil fuels, the race is on to discover renewable energy solutions. As an alternative, researchers from the University of Cincinnati have found a way to convert solar energy and carbon dioxide into sugars to create...
Exoplanet's Spectrum Revealed
MUNICH, Germany, Jan. 13, 2010 – By studying a triple planetary system that resembles a scaled-up version of our sun’s family of planets, astronomers have obtained the first direct spectrum of a planet orbiting a distant star, a milestone in the search for life elsewhere in...
Villa Solar Set for June in Madrid
Dec 2, 2009 — At a time when several European countries are proposing cuts to feed-in tariffs, known in the past as a great motivator for the solar industry, cutting-edge research and innovation in sustainable development and renewable energy are ramping up for a...
3-D PV Cell Folds, Travels
ATLANTA, Nov. 5, 2009 – A new technology for growing nanostructures on optical fibers can be used to make 3-D photovoltaic systems foldable and portable, no longer confined to traditional locations such as rooftops.
Small (and Big) Talk at FiO
SAN JOSE, Calif., Oct. 15, 2009 -- The superbig and the supersmall were the subjects of two plenary sessions Monday at Frontiers in Optics 2009. In the first session, Andrea M. Ghez, professor of physics and astronomy at UCLA, a leading expert in observational astrophysics, explained...

The Search for Other Earths
Oct 1, 2009 — In recent years, astronomers have discovered more than 350 extrasolar planets, or exoplanets. But typical detection techniques are best suited for finding planets that are very dissimilar to Earth in terms of size and orbital characteristics, and it...
Fire Threatens Observatory
LOS ANGELES, Sept. 1, 2009 – A wildfire raging in Angeles National Forest is threatening the 105-year-old Mount Wilson Observatory, home to several of the most technologically advanced facilities in the world for studying astronomical objects with unprecedented resolution and...
Coating Boosts Solar Power
TROY, N.Y., Nov. 5, 2008 -- A new antireflective coating boosts the amount of sunlight captured by solar panels and allows those panels to absorb the entire solar spectrum from nearly any angle, overcoming two major hurdles facing solar energy. The discovery moves academia and...
Laser Comb is Ultraprecise
GARCHING, Germany, Sept. 5, 2008 -- A laser frequency comb, a new calibration technique that combines the incredible precision of an atomic clock with the sharp spectral features of laser light, has been used at a solar telescope to measure the sun's spectrum in infrared light. Such...
Mike Splain Named VP at Sun
Apr 29, 2008 — Mike Splain, chief engineer and CTO for Sun Microsystems' Systems Group, has been named executive vice president of its Microelectronics Group. A Sun fellow with 20 years of service, he previously worked at Ridge Computers, Vitesse Semiconductor,...
Some Auroral Glow is Polarized
WASHINGTON, April 29, 2008 -- An international team of scientists has detected that some of the glow of Earth's aurora is polarized, an unexpected state for such emissions. Measurements of this newfound polarization in the northern lights may provide scientists with fresh...
Sun Wins $44M to Speed Chips
SANTA CLARA, Calif., March 24, 2008 -- Sun Microsystems Inc. announced today it has received $44 million to speed computing by interconnecting an array of microchips into one "macrochip" using lasers instead of copper wires. If successful, the program could create a kind of...
100K Dpi Printing Unveiled
ZURICH, Switzerland, Sept. 11, 2007 -- A new technique allows the printing of particles as small as 60 nanometers -- roughly 100 times smaller than a human red blood cell -- in complex patterns at a resolution of 100,000 dots per inch. The level of control offered by the nanoprinting...
