Spectroscopy and Machine Learning Focus Lens on Far Reaches of the Universe
MELBOURNE, Australia, Oct. 11, 2022 — Researchers from the ARC Centre of Excellence for All Sky Astrophysics in 3 Dimensions (ASTRO 3D) and the University of New South Wales (UNSW) Sydney spectroscopically confirmed a number of strong gravitational lenses that were initially identified using convolutional neural networks (CNNs). “Our spectroscopy allowed us to map a 3D picture of the gravitational lenses to show they are genuine and not merely chance superposition,” professor Kim-Vy Tran said. A machine
Photonics Technologies at the Fore as First James Webb Space Telescope Images Released
WASHINGTON, D.C., July 12, 2022 — The first images from the James Webb Space Telescope are being released today, following an initial release of a “teaser” image July 7, and a subsequent preview image released July 11 during a press conference by U.S. President Joe...
Imaging the Oldest Light in the Universe with the BICEP Array
Nov 27, 2019 — The field of experimental cosmology is unique among the physical sciences. It uses the entire observable universe as a laboratory, within which examinations of large-scale physical phenomena can help physicists answer some of the most fundamental...

GREENBELT, Md., Dec. 19, 2013 — The final three of 18 primary mirrors built for the James Webb Space Telescope (JWST) have arrived at Goddard Space Flight Center for integration prior to a scheduled launch in 2018, principal optical subcontractor Ball Aerospace & Technologies...
Ball Ships First Webb Telescope Mirrors
BOULDER, Colo., Sept. 24, 2012 — The first two of the 18 beryllium primary mirror segments that comprise NASA’s James Webb Space Telescope arrived at Goddard Space Flight Center last week.
MTD to supply parts for SwissFEL
STOKE-ON-TRENT, UK – Engineering firm Midland Tool and Design (MTD) is producing components for use in a facility similar to the Large Hadron Collider (LHC). The company will manufacture the components for Switzerland’s Paul Scherrer Institute’s SwissFEL...
LHC Experiments Shed Light on Primordial Universe
GENEVA, Aug. 14, 2012 — The primordial particles of matter that existed just after the big bang are now being re-created in the Large Hadron Collider to advance understanding of the kind of matter that existed in the first seconds of the universe.
MTD to Supply Parts for FEL Project
STOKE-ON-TRENT, England, July 11, 2012 — Midland Tool and Design is producing components for use in a facility similar to the Large Hadron Collider.
Spectrometer-on-a-chip shows young universe
GREENBELT, Md. – NASA scientists hoping to get a glimpse of the universe in its youth may finally do so using a revolutionary instrument on a chip called MicroSpec. Scientists know what the universe looked like when it was a baby and how it looks today, but...
Laser Spectroscopy Precisely Measures Antiproton
GARCHING, Germany, Aug. 1, 2011 — A new laser spectroscopy measurement providing the most accurate weight of antimatter yet reveals the mass of the antiproton (the proton’s antiparticle) down to 1.3 parts per billion. It is widely believed that, at the beginning of the...
10-Year Study Shows Electron Is Surprisingly Spherical
LONDON, May 26, 2011 — Using a very precise laser, physicists have made the most accurate measurement of the shape of an electron, deeming it 0.000000000000000000000000001 cm from being perfectly round. This means that if the electron were magnified to the size of the...
Fahrenheit -459: Neutron Stars and String Theory
DURHAM, N.C., Dec. 30, 2010 — Ultrachilled atoms trapped in a "bowl" made of laser light and then placed in a magnetic field have allowed scientists to measure the viscosity of a gas often considered to be the sixth state of matter. The measurements verify that this gas can be...
IR ‘Eyes’ to See Back in Time
GREENBELT, Md., Dec. 30, 2009 – NASA’s James Webb Space Telescope’s Mid-Infrared Instrument (MIRI) detectors will see even further back in time than its predecessor, the Hubble Space Telescope, when it is sent into orbit in 2014. The Webb, the largest space observatory every...
SPIE O+P Blog: Hornet's Nest
Aug 3, 2009 — Features Editor Gary Boas documents his experience at SPIE Optics + Photonics 2009, including special events marking the 400th birthday of the telescope and the 40th anniversary of the moon landing.
Incandescent Nanotube Lamp
LOS ANGELES, Calif., May 7, 2009 – In an effort to explore the boundary between thermodynamics and quantum mechanics – two fundamental, yet seemingly incompatible theories of physics – a team from the UCLA Department of Physics and Astronomy has created the world's smallest...
EU Unveils Astronomy Plan
MUNCHEN, Germany, Nov. 26, 2008 – Thanks to the world’s most successful optical observatory, European Southern Observatory’s (ESO) Very Large Telescope, and the cutting-edge facilities in radio astronomy and in space, Europe has emerged as a global leader in astronomy. In an...
Physicists Collide with Doomsayers
Sep 10, 2008 — Recently, theoretical chemist Otto Rössler and others have protested the Large Hadron Collider at CERN in Geneva, fearing that the world’s largest particle accelerator will produce massive black holes that will swallow Earth. Proponents of the...
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...
Plug Pulled on FUSE
WASHINGTON, Oct. 19, 2007 -- After an eight-year run that gave astronomers a completely new perspective on the universe, NASA said it terminated its Far Ultraviolet Spectroscopic Explorer mission Thursday. The satellite, known as FUSE, became inoperable in July when it lost its...
