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.
CCD Sensors Tailored to Space Applications
Nov 1, 2013 — Designing image sensors for the ESA’s Euclid mission demonstrates the importance of customization for specialty uses and harsh environments. Adapting commercial electronic parts for space applications usually consists of little more than the...
Dark energy camera takes first pictures
CERRO TOLOLO, Chile – After eight years in the making, the most powerful sky-mapping machine ever created, the 570-megapixel Dark Energy Camera (DECam), achieved first light on Sept. 12. The camera was constructed at Fermi National Accelerator Laboratory in Batavia,...
Dark Energy Camera Records First Images
CERRO TOLOLO, Chile, Sept. 17, 2012 — After eight years of planning and construction, the most powerful sky-mapping machine ever created, the 570-megapixel Dark Energy Camera (DECam), achieved first light on Sept. 12. The camera was constructed at Fermi National Accelerator Laboratory...
Webb Space Telescope Funded, for Now
WASHINGTON, Sept. 20, 2011 — Two months after a House committee recommended defunding the project altogether, the James Webb Space Telescope was saved by a Senate subcommittee, which is allocating $530 million to the international project in 2012. The 2012 appropriations bill...
Hubble Proves Cosmic Acceleration
LEIDEN, the Netherlands, April 5, 2010 — A group of astronomers led by Tim Schrabback of the Leiden Observatory conducted an intensive study of more than 446,000 galaxies, resulting in independent confirmation that the expansion of the universe is being accelerated by the mysterious...
Dark Matter Measures Age of Universe
DAVIS, Calif., March 23, 2010 — Astronomers from the United States and Europe have used a gravitational lens – a distant, light-bending clump of dark matter – to make a new estimate of the Hubble constant, which determines the size and age of the universe. The Hubble constant...
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,”...
Rehabbed Hubble Opens Eyes
WASHINGTON, Sept. 9, 2009 – Colorful multiwavelength pictures of far-flung galaxies, an eerie "pillar of creation" and a butterfly-shaped nebula are some of the new observations taken by new and upgraded instruments on the renovated Hubble Space Telescope and released to the...
Mount Wilson Fire Threat Wanes
LOS ANGELES, Sept. 3, 2009 – A massive effort by thousands of firefighters on the ground and by retardant-carrying aircraft appears to have greatly lessened the threat that a massive wildfire poses to the Mount Wilson Observatory – home to two historic telescopes – officials...
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...
The Universe Used as a Lens
CHICAGO, Feb. 25, 2009 – Scientists are harnessing the cosmos as a scientific “instrument” in their quest to determine the makeup of the universe. The University of Chicago’s Evalyn Gates calls the instrument “Einstein’s telescope.” The instrument is actually the...
Sci-Fi, Science Collide at CERN
GENEVA, Feb. 13, 2009 -- When officials at CERN were contacted by Sony Pictures in early 2007 about filming part of the upcoming Tom Hanks movie "Angels & Demons" there, the lab, home to the Large Hadron Collider particle accelerator, saw it as an opportunity to promote...
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...
Laser Pulse Produces Positrons
LIVERMORE, Calif., Nov. 18, 2008 -- More than 100 billion particles of antimatter have been created by using a short-pulse, ultraintense laser to irradiate a gold sample the size of the head of a push pin. The antimatter, also known as positrons, shoots out of the target in a...
CERN Parties Like It’s 2009
GENEVA, Oct. 21, 2008 -- Despite a malfunction that has shuttered the world’s largest particle accelerator until 2009, officials at CERN, the organization hosting the ailing atom smasher, held an inauguration ceremony today. Attending the celebration to inaugurate the...
Jefferson Lab Upgrade OK'd
NEWPORT NEWS, Va., Sept. 16, 2008 -- Less than a week after the largest particle accelerator in the world launched its first beams near Geneva, Switzerland, the US Department of Energy has approved construction of a $310 million project at the Thomas Jefferson National Accelerator...
Collider Beams Up at CERN
GENEVA, Sept. 10, 2008 -- After 20-plus years of planning, billions of dollars, lawsuits, and even death threats, the first beam of protons in the Large Hadron Collider (LHC) particle accelerator was successfully steered around a 17-mile racetrack at nearly the speed of...
Threats Won't Stop Collider
GENEVA, Sept. 9, 2008 -- Despite death threats, lawsuits, and even physicist Stephen Hawking betting against it, the Large Hadron Collider, the world's largest particle accelerator, will be turned on Wednesday. The LHC operates in a circular tunnel 27 km (16.7 miles) in...
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...
Giant Camera Heads to Hawaii
EDINBURGH, Scotland, Feb. 22, 2008 -- The UK Astronomy Technology Centre (UK ATC) at the Royal Observatory Edinburgh yesterday shipped its biggest and most complex instrument ever -- a four-ton camera the size of a car that is expected to make major discoveries about the origins of the...
New Name Sought for GLAST
WASHINGTON, Feb. 8, 2008 -- NASA announced Thursday it is inviting people from around the world to submit a new name for the Gamma-ray Large Area Space Telescope, known as GLAST, before the satellite launches in mid-2008 to observe some of the most powerful forces known in the...
'Squeezed Light' Record Set
HANOVER, Germany, Jan. 29, 2008 -- An extremely high-quality green laser beam has allowed a record number of photons to be placed in a specific order for use in gravitational wave detectors. Ordering the photons reduced fluctuations in the intensity of the light by 90 percent. This...
NIR Imaging for Deep Space
Jun 1, 2007 — What is dark energy? How much is there? And what is it doing to the universe? A growing number of scientists is hoping to answer those complex questions as preparations are made for the 2011 launch of the Joint Dark Energy Mission sponsored by...
