An Actively Cooled Mid-IR Telescope Peers Through Space Dust
Jun 1, 2022 — When the European Space Agency’s (ESA’s) Herschel Space Observatory revealed that the universe was far richer in star-forming dust than previously thought, the engineers who were developing a new mid-infrared space instrument recognized that their project’s potential had expanded. The observatory, with its far-IR camera and low-resolution spectrometer covering wavelengths down to 55 μm, enabled scientists to discover an unexpected abundance of dusty galaxies at very high...
Cosmic Lens Helps Hubble Capture Image of Most Distant Star Ever Seen
BERKELEY, Calif., April 3, 2018 — Gravitational lensing — the bending of light by massive galaxy clusters in the line of sight — has occurred during a rare cosmic alignment, magnifying a star more than 2,000 times. The phenomenon allowed astronomers to capture an image...
MUSE Offers 3-D View of Distant Galaxies
CERRO PARANAL, Chile, March 6, 2014 — Far-away galaxies and bright stars could feel closer than ever, thanks to a new astronomical instrument that is a decade in the making.
Rare Brown Dwarf Discovery Aids Exoplanet Study
SOUTH BEND, Ind., Jan. 22, 2014 — The discovery of a very rare type of brown dwarf substar could soon provide a better understanding of exoplanets.
Powerful Exoplanet Camera Unveiled
LA SERENA, Chile, Jan. 9, 2014 — After nearly a decade of development, a powerful exoplanet camera that detects IR radiation to image and analyze planets from other solar systems is now operational.
Dark matter halos may contain stars
LOS ANGELES and IRVINE, Calif. – Stars kicked to the edges of space during violent collisions and mergers with other galaxies can get tossed into large, invisible cocoons of dark matter, which might explain why astronomers say they see more light in the universe than it seems they...
Dark Matter Halos May Contain Stars
LOS ANGELES and IRVINE, Calif., Oct. 25, 2012 — Stars kicked to the edges of space during violent collisions and mergers with other galaxies can get tossed into large, invisible cocoons of dark matter, which might explain why astronomers say they see more light in the universe than it seems they...
Astronomers decry UK’s defunding of Hawaii telescopes
HARWELL, UK — May 31 was “a sad day for British astronomy,” according to David Southwood, president of the Royal Astronomical Society (RAS). That was the day the Science and Technologies Facilities Council (STFC) announced that it would close —...
UK’s Defunding of Hawaii Telescopes Decried
HARWELL OXFORD, England, June 1, 2012 — Thursday was "a sad day for British astronomy," according to the president of the Royal Astronomical Society. That was the day the UK’s Science and Technologies Facilities Council (STFC) announced it would close — or transfer to other...
MIRI Ready to be Shipped to NASA
HEIDELBERG, Germany, May 18, 2012 — The first instrument for the James Webb Space Telescope was completed by the Max Planck Institute for Astronomy and handed over to NASA.
Stoking the star-maker machinery
Mar 1, 2011 — They’re making stars in Chile, Huck, and it did take a long time – about 10 years – but overnight on Jan. 21-22, there were five new stars in the Southern sky. You wouldn’t have been able to see them with your eyes, but they...
SOFIA Completes First Science Flight
MOFFETT FIELD, Calif., Dec. 17, 2010 — NASA's Stratospheric Observatory for Infrared Astronomy, or Sofia, recently completed the first of three science flights, demonstrating the aircraft's potential to make discoveries about the infrared universe. The high-tech German-built...
Taking the Twinkle Out of the Stars
TUSCON, Ariz., Aug. 4, 2010 — Star-gazers beware. Astronomers have developed a way to take the twinkle out of the night sky, but it’s really not as sinister as it may sound. Green guide star laser beams, used to sense turbulence in the atmosphere that badly degrades large...
e2v Delivers Over 150 Imaging Sensors For Space Mission
ESSEX, England, July 29, 2010 — High performance imaging sensors manufacturer e2v technologies plc has reached a milestone, delivering over 150 CCD imaging sensors for the European Space Agency’s (ESA) galaxy mapping mission, Gaia. Anticipated to launch in 2012, Gaia will...
Microshutters Are Key to Webb
GREENBELT, Md., July 6, 2010 — Shutters as small as the width of a human hair are a vital component in the James Webb Space Telescope (JWST), giving the spacecraft the ability to see huge distances in the cosmos. The so-called microshutters, which have now arrived at the European...
Women’s Hall of Fame Welcomes Poyneer
LIVERMORE, Calif., April 29, 2010 — Lisa Poyneer has been inducted into the Alameda County Women’s Hall of Fame for her work in adaptive optics and the development of the Gemini Planet Imager (GPI), which will be the world’s most powerful astronomical adaptive optics...
Wish upon a star
MUNICH, Germany, and MONTREAL – When searching outer space for sharp images of remote stars, large-scale astronomical telescopes employ adaptive optics to actively compensate for atmospheric disturbances. However, these devices need control mechanisms in the form of “guide stars,”...
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...
IR Astronomy Pioneer Dies
TUCSON, Ariz., June 22, 2009 -- Infrared astronomy pioneer Frank J. Low died June 11, according to the University of Arizona, his employer since 1965. He was 75. Low was a solid-state physicist who became a leader in the new field of infrared astronomy after inventing the...
Plasmas Made From Molecules
VANCOUVER, British Columbia, Nov. 24, 2008 -- A new technique for making ultracold plasmas out of molecules instead of trapped atoms brings scientists a big step closer to unlocking the secrets of the most abundant form of matter in the universe. A plasma, or ionized gas, can be as...
Physicists Get Genius Grants
CHICAGO, Sept. 23, 2008 -- An optical physicist who demonstrated that power can be transmitted wirelessly, a physicist who explores the mysterious behavior of quantum systems, and an astrophysicist working to improve the spatial resolution and precision of instruments used to...
Keck Observatory Awarded $2M to Improve Interferometer
KAMUELA, Hawaii, Dec. 19, 2006 -- The National Science Foundation has awarded the W. M. Keck Observatory $2 million to improve the sensitivity and resolution of the Keck Interferometer. The improvements will enable the instrument to detect Jupiter-sized planets around other stars...
WISE to Map the Sky in IR Light
PASADENA, Calif., Oct. 19, 2006 -- After eight years of study, NASA has approved the construction of an unmanned satellite that will scan the entire sky in infrared light to reveal nearby cool stars, planetary "construction zones" and the brightest galaxies in the universe. An...
