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...

5-Year Search for Dark Energy Begins
BERKELEY, Calif., May 24, 2021 — The Dark Energy Spectroscopic Instrument (DESI) has begun its five-year search for dark energy. The device, housed at Kitt Peak National Observatory near Tucson, Ariz., will aim its robotic array of 5000 fiber optic “eyes” at the night...
Atom Interferometry, Demonstrated in Space, Opens Measurement Possibilities
MAINZ, Germany, May 4, 2021 — A German team successfully demonstrated atom interferometry in space on board a sounding rocket. Atom interferometry uses the wave character of atoms to make high-precision measurements. The application can be used to measure the gravitational field...
Photonic Return Charts Course for Laser-Ranging Experiments
Dec 8, 2020 — Extensively in the last 50 years, intermittently in the last decade, and with newfound success in receiving a return on their efforts this past summer, NASA scientists have taken aim at the moon with high-power laser beams. Receiving even a faint...
IR Imaging, AO in Spotlight as 3 Scientists Awarded Nobel Prize in Physics
WASHINGTON, D.C., Oct. 6, 2020 — Laureates Roger Penrose, Reinhard Genzel, and Andrea Ghez have been awarded the 2020 Nobel Prize in physics for discoveries related to black hole formation (Penrose) and of a black hole at the center of the Milky Way (Genzel and Ghez). Penrose,...
Primary Mirror Completed for NASA’s Roman Space Telescope
GREENBELT, Md., Sept. 15, 2020 — The Nancy Grace Roman Space Telescope’s primary mirror has been completed, NASA announced. The telescope will have a field of view 100× greater than the Hubble Space Telescope, and it will use infrared light to study hidden structures....
Robust Laser Technology Will Enable Satellite to Measure Greenhouse Gas
BERLIN, July 30, 2020 — The MERLIN satellite, a collaboration between DLR RfM in Germany and CNES in France, will use a radar-like laser system to measure the methane concentration in Earth’s atmosphere. The satellite’s Integrated Path Differential Absorption...
Quantum Entanglement Demonstrated Aboard Orbiting CubeSat
SINGAPORE, July 1, 2020 — An international research team led by the National University of Singapore (NUS) has generated and detected quantum entanglement onboard a CubeSat nanosatellite weighing less than 2.6 kg and orbiting Earth. CubeSats are low-resource, cost-effective...
Partners to Boost European Supply of Space-Qualified Laser Crystals
HANNOVER, Germany, April 23, 2020 — Laser Zentrum Hannover eV (LZH) will partner with Optomaterials srl in Italy and Altechna Coatings UAB in Lithuania to develop a European supply chain for space-qualified, high-performance laser crystals made of alexandrite. The EU project, named...
