If you've been hiding out in the lab, constantly checking your March Madness bracket, or escaping the cold to find any ounce of warmth (like me!), chances are you may have missed some exciting news. March turned out to be quite a busy month in the Adaptive Optics world, so here’s what you missed:
1. Exoplanet imaging in under a minute
At the recent AAAS 2015 annual meeting, Bruce Macintosh from Stanford University and Principal Investigator for the Gemini Planet Imager (GPI), discussed that there are over 1,000 confirmed planets due to the help of Adaptive Optics. In order to start really understanding a planet and its characteristics, you need to look at the composition of its atmosphere. Astronomers have relied heavily on the adaptive optics technique, allowing for distortion correction of the atmosphere using a deformable mirror. This has had proven success in regards to GPI, which uses a BMC deformable mirror (4K-DM), as part of its adaptive optics system. It can image planets in about a minute, which used to take up to an hour! GPI recently imaged the HR8799 star system, with three orbiting planets. Since November 2013, GPI has imaged 600 stars and identified 50-60 new planets.
2. 2nd quadruple star system discovered
More exciting news from the Astronomy world was the discovery of a massive planet with a quadruple star system only 125 light-years from Earth. Discovered by the Jet Propulsion Laboratory, they were able to detect the fourth star after fitting the telescopes at the Palomar Observatory with a Robo-AO adaptive optics system. Utilizing the AO technique allowed astronomers to pick up on the faint star that couldn’t be seen before. Below is a diagram illustrating the discovered Ari 30 alongside its pair in a binary systems. Before this detection, only one other planet in a quadruple star system had been discovered before. More sightings are being predicted as exoplanets are found, with the help of Adaptive Optics systems of course!

3. The most valuable brains
Congratulations to Scientists Winfried Denk, Arthur Konnerth, Karel Svoboda and David Tank for being awarded the world’s most valuable neuroscience prize, The Brain Prize, for the invention and development of two-photon microscopy! Two-photon microscopy is helping researchers to understand the human brain and how its networks process information, such as nerve cell communication. It has also enabled the study of nerve cells that control vision, hearing and movement. Recent work has been carried out to implement adaptive optics systems on two-photon microscope systems around the word, including locations such as the Howard Hughes Medical Institute, Institute Langevin at CNRS and Boston University. Standing on the shoulders of giants to improve imaging of the brain with AO!
