Perfecting Technology to One Day Look for Signs of Alien Life

The HR 8799 planetary system is the first solar system beyond our own that astronomers directly imaged. Captured in 2008 using Keck Observatory's near-infrared adaptive optics, the picture revealed three planets (labeled 'b', 'c', and 'd') orbiting a dusty young star named HR 8799 (center). In 2010, the team announced they detected a fourth planet in the system (labeled 'e'). The HR 8799 system is located 129 light-years away from Earth. Credit: NRC-HIA/C. MAROIS/W. M.

Super Slow Motion Crystal Structures

News

Laser beams are used to change material properties precisely. However, the underlying processes generally happen unimaginably fast and at such a small scale that they have so far eluded direct observation. Researchers have now managed to film, for the first time, the laser transformation of a crystal structure with nanometre resolution and in slow motion in an electron microscope.
