NASA-developed deformable mirrors to cancel out aberration

NASA Designs New Space Telescope Optics to Find a New Earth
http://www.nasa.gov/topics/technology/features/SpaceTechOpticsBelikov.html

Although hundreds of planets orbiting other stars have been discovered in the past 15 years, we cannot yet answer the age-old question of whether any of these planets are capable of sustaining life. However, new NASA technology may change that, by giving us our first look at distant planets that not only are the right size and traveling in the temperate habitable zone of their host star, but also show signs of potential life, such as atmospheric oxygen and liquid water.

Research scientists at NASA's Ames Research Center, Moffett Field, Calif., are developing new space telescope optics that won’t just detect planets similar to Earth, but actually take photos of them. To take photos, called “direct imaging,” a new technology will be used called phase-induced amplitude apodization (PIAA). In development since 2003, it is a proof-of-concept and technology tested prototype that is a strong candidate for NASA's upcoming direct imaging exoplanet missions expected to launch in the 2020 decade and beyond.

The PECO mission (a space telescope) was based in this technology, for example. Nothing new, apart from new tests.

I understand "photos" as pixel unresolved images of that planets, not really resolved pictures (to do that we will need interferometry)
