Astronomy

The Stratospheric Observatory for Infrared Astronomy operates from a modified Boeing 747 and enables unique spectroscopy and imaging not possible with ground-based IR observatories.
23 August 2016
Lightweight additive-technology metamaterials, and optical systems that combine interferometry with fixed-pupil segments, enable detection of possible extraterrestrial life from large ground-based telescopes.
30 July 2016
A new instrument on the 4m Mayall Telescope at Kitt Peak National Observatory will use 5000 robotic fiber positioners to create a 3D redshift map of the universe to study dark energy.
13 July 2016
A new three-probe measurement system has been developed and implemented with a data-stitching algorithm to improve its accuracy.
7 July 2016
Speckle imaging, an older technique for obtaining diffraction-limited resolution with large telescopes, is back in a big way thanks to electron-multiplying CCDs.
24 June 2016
An ultrastable spectrophotometry method can be used to mitigate the effects of telescope pointing jitter and primary mirror deformation.
