Asteroids, hydrogen make great recipe for life on Mars

A new study reveals asteroid impacts on ancient Mars could have produced key ingredients for life if the Martian atmosphere was rich in hydrogen. An early hydrogen-rich atmosphere on Mars could also explain how the planet ...

Attosecond photoelectron spectroscopy accelerated

Laser physicists have succeeded in reducing the acquisition time for data required for reliable characterization of multidimensional electron motions by a factor of 1000.

Processes in the atomic microcosmos revealed

Physicists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have successfully generated controlled electron pulses in the attosecond range. They used optical traveling waves formed by laser pulses of varying wavelengths. ...

Scientists develop new metasurfaces for deep UV-imaging

Russian researchers have developed a new material that converts infrared light to ultrashort pulses of ultraviolet. For this purpose, the scientists exposed silicon film to a laser so that its relief adjusted under the light ...

Attosecond camera for nanostructures

Physicists based at Ludwig-Maximilians-Universitaet (LMU) in Munich and the Max Planck Institute for Quantum Optics have observed a nanoscale light-matter phenomenon which lasts for only attoseconds.

Ultra-fast X-ray lasers illuminate elusive atomic spins

A quick flash of light can make ordinary materials extraordinary, potentially inducing qualities such as the perfect efficiency of superconductivity even at room temperature. But these subatomic transformations are infamously ...

A sense for infrared light

Laser physicists from the Max Planck Institute of Quantum Optics developed a measuring system for light waves in the near-infrared range.
