Bringing Habitable Planets to Light with Faster Adaptive Optics
Jul 28, 2020 — At the heart of every imaging system, from endoscopes to extremely large telescopes, is the pursuit of a perfect image, extracting as much information as possible from every acquired photon. No matter how well designed the system, however,...
From Masers to Lasers in Space — and at the Cinema!
Oct 7, 2016 — Sixty years ago, physicists Charles Hard Townes, James P. Gordon and H.J. Zeiger demonstrated the maser (microwave amplification by stimulated emission of radiation). It wasn’t long before Townes and fellow physicist Arthur Schawlow proved...
‘Astro-Comb’ Rediscovers Venus to Find Exoplanets
CAMBRIDGE, Mass., Oct. 28, 2014 — Examining Venus’ influence on the solar spectrum could help astronomers discover Earth-like planets orbiting distant stars. A team from the Harvard-Smithsonian Center for Astrophysics is developing a laser-based frequency comb to measure this...
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.
Uncooled IR camera reveals mysteries of space
Jul 1, 2012 — Even three years after its liquid helium cooling supply was exhausted, the maverick Infrared Array Camera (IRAC) on NASA’s Spitzer Space Telescope continues to capture new and wondrous views of the universe. Launched in 2003, the Spitzer...
Lasers probe planet formation
LIVERMORE, Calif. – Experiments using high-power lasers could help scientists understand how planets are formed. Phase changes in liquid magmas at pressures and temperatures that exist deep inside Earth-like planets could provide insight into the processes that govern...
Laser Research Provides Insight into Planet Formation
LIVERMORE, Calif., Feb. 14, 2012 — Phase changes in liquid magmas at pressures and temperatures that exist deep inside Earth-like planets could provide insight into the processes that govern planet formation.
Marking 10 Years of Adaptive Optics at the VLT
HEIDELBERG, Germany, Nov. 30, 2011 — In November 2001, the NACO instrument — recently added to the European Southern Observatory’s Very Large Telescope (VLT) in northern Chile — captured its first light. Since then, its ability to bring stellar objects into sharp...
Boston Micromachines Wins Contracts
Aug 1, 2011 — Boston Micromachines Corp. of Cambridge, Mass., has been awarded $1.2 million in contracts for space imaging research by NASA’s Small Business Innovation Research program. In the first of two projects, the company will develop compact,...
NASA Awards Contracts to Boston Micromachines
CAMBRIDGE, Mass., June 9, 2011 — Boston Micromachines Corp. has been awarded $1.2 million by NASA to develop compact, ultralow-power, high-voltage multiplexed drive electronics suitable for integration with the company’s deformable mirrors in space-based wavefront control...
Exoplanet's Spectrum Revealed
MUNICH, Germany, Jan. 13, 2010 – By studying a triple planetary system that resembles a scaled-up version of our sun’s family of planets, astronomers have obtained the first direct spectrum of a planet orbiting a distant star, a milestone in the search for life elsewhere in...
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...
Optics to Spy Alien Worlds?
GREENBELT, Md., Sept. 24, 2008 – Roughly 13 years ago astronomers found and confirmed the existence of the first planet outside the solar system. Since then, scientists have confirmed nearly 300, most of which are gas giants like Jupiter. Most of these detections, however, have...
Astro-Combing for Planets
CAMBRIDGE, Mass., April 8, 2008 -- The discovery of Earth-sized planets outside our solar system, or "exoplanets," has reportedly been made possible with a laser-measuring device that will advance the resolution of current planet-finding techniques. The new device, called an...
