The dream of directly visualizing planets like Earth outside of the solar system got a little closer with a new technique developed by an international group of astronomers. As a demonstration, they have used it to study the Alpha Centauri system (which is closest to us, 4.3 light-years from here) and may already have found a planet there.
The project, called NEAR (English acronym for New Lands in the Alfa Centauri region) involved installing updates for one of the VLT instruments, the Very Large Telescope, in Chile. The mid-infrared camera received a new coronograph that blocks the light of the imaginary stars and thus enables the observation of less bright objects in their surroundings. In addition, it was used in conjunction with one of the VLT telescopes with a malleable secondary mirror that compensates for image distortion caused by atmospheric turbulence in real time.
