Webb’s Exoplanet Observations Demonstrate Telescope's Strengths
WASHINGTON, D.C., Sept. 12, 2022 — NASA’s James Webb Telescope has captured the first clear evidence for carbon dioxide in the atmosphere of a planet outside out solar system, shortly after taking its first image of an exoplanet. The observations made with the powerful infrared telescope are not only providing insight into the formation and composition of planetary objects, but also prove the advantages of space telescopes outside the Earth’s orbit. WASP-39 b, the planet upon which Webb discovered carbon
NASA Partners with Harvard on Metasurface Polarimetry
CAMBRIDGE, Mass., June 11, 2021 — NASA earth scientist Kerry Meyer and researchers at Harvard University are developing metasurface technology capable of analyzing light along four polarization directions. With one flat optical component, intensity, linear polarization (horizontal...
Nanohmics to Test Hyperspectral Imager on International Space Station
AUSTIN, Texas, Oct. 27, 2020 — Nanohmics Inc., in collaboration with the University of Maryland and the NASA Langley Research Center, will send a prototype compact hyperspectral imager to the International Space Station (ISS) where it will be tested for calibration. The launch...
Habitable Exoplanets to Be Studied with Help of AI and Photonics
SYDNEY, Oct. 23, 2020 — Researchers from the University of Sydney developed a sensor capable of correcting the distortion of starlight caused by heat variations in Earth’s atmosphere. The sensor would allow ground-based telescopes to study habitable exoplanets. The...
CU-Boulder CubeSat Uncovers Source of Electrons in Earth’s Inner Radiation Belt
BOULDER, Colo., Jan. 8, 2018 — A 60-year-old mystery about the source of energetic, potentially damaging particles in Earth's radiation belts has been solved using data from a shoebox-sized CubeSat satellite built and operated by students at the University of Colorado Boulder...
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...
Lasers to Clean Up Space Junk
CANBERRA, Australia, April 2, 2014 — A new approach to eliminating space debris may be reminiscent of a sci-fi movie scene or video game, but it could actually prove more practical than options previously studied.
Conference to Explore Laser-based Weather Control
GENEVA, Aug. 30, 2013 — Ultrashort-pulse lasers as an emerging tool for controlling the weather will be the topic of interest at a gathering of atmospheric physicists, meteorologists and climatologists next month at the World Meteorological Organisation in Geneva. The...
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...
Traffic Pollution Analyzed by IR Sensing
MADRID, Spain, Sept. 10, 2010 — Scientists at Universidad Carlos III de Madrid are testing infrared (IR) remote sensing technology to evaluate the pollutant emissions associated with motor vehicle traffic. The technology could analyze all the gases of environmental interest with...
Holograms lighten the payload of unmanned aerial vehicles
ARLINGTON, Va. – US Air Force scientists have devised a way to make un-manned aerial vehicles (UAVs) better eyes in the sky, besides making them lighter and more efficient. Also known as drones or pilotless aircraft, UAVs increasingly are being used for...
Letters to the Editor
Jul 1, 2010 — Solar array size important In Anne L. Fischer’s interesting article titled “Solar-heated bridges, roads” (February 2010, p. 38), she did not comment on the size of the solar array that would be needed. Because the roadway itself is...
e2V Sensors to Study the Planet Venus
CHELMSFORD, UK, May 20, 2010 — On Friday, May 21, the Japan Aerospace Exploration Agency’s (JAXA) Venus Climate Orbiter “Akatsuki” is scheduled to be launched into space to study the planet Venus, carrying with it CCD imaging sensors made by e2v technologies. ...
Chile Chosen as E-ELT Site
ANTOFAGASTA, Chile, May 7, 2010 — The European Southern Observatory (ESO) Council has selected Cerro Armazones as the baseline site for the planned 42-m European Extremely Large Telescope (E-ELT). Cerro Armazones is a mountain at an altitude of 3060 m in the central part of...
Earth’s UV Signature Revealed
BOULDER, Colo., Jan. 19, 2010 – On its way to rendezvous with a comet, the spacecraft Rosetta turned an eye toward Earth and recorded its ultraviolet signature. The information it collected may help astrobiologis...
Multibeam Lasers Emit in IR
CAMBRIDGE, Mass., Nov. 30, 2009 – An international team of applied scientists demonstrated compact, multibeam and multiwavelength lasers emitting in the infrared. Typically, lasers emit a single light beam of a well-defined wavelength; with their multibeam abilities, the new lasers...
Commercializing the Nobel-Winning Discovery of the Bose-Einstein Condensate
Jul 1, 2009 — Bose-Einstein technology reduces production time and cost for "ultracold" matter experiments.
Technology: Bump in the Night
Jan 1, 2009 — On a moonless night when the sky seems at its darkest, a perpetual atmospheric short-wave infrared (SWIR) light source is present, but typically goes undetected. About 90 km (approximately 56 miles) high in the Earth’s atmosphere, solar energy is...
Grad Students Receive NASA Fellowships
Jun 16, 2008 — Montana State University (MSU) electrical engineering graduate students David Hoffman and Amin Nehrir have each received a $30,000 fellowship through NASA's Graduate Student Researchers Program, giving them the opportunity to work with some of...
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...
Robert Kerr Appointed Director of the Arecibo Observatory
Feb 7, 2007 — Robert B. Kerr, PhD, an astronomer and atmospheric scientist, has been appointed as director of the Arecibo Observatory in Arecibo, Puerto Rico. The observatory is managed on behalf of the National Science Foundation (NSF) by Cornell University's...
