Making and controlling crystals of light

Optical microresonators convert laser light into ultrashort pulses travelling around the resonator's circumference. These pulses, called "dissipative Kerr solitons," can propagate in the microresonator maintaining their shape.

OSIRIS-REx's final four sample site candidates in 3-D

This animated flyover of each of the four candidate sample collection sites on asteroid Bennu, selected by NASA's OSIRIS-REx asteroid sample return mission, was produced using close-range data from the OSIRIS-REx Laser Altimeter ...

Laser solitons: Theory, topology and potential applications

In almost all situations, even in a vacuum, light cannot travel endlessly without dissipating. Pulses of light known as solitons that propagate along fibres for long distances without changing their shape or losing focus ...

Star nearing death offers a preview of our Sun's fate

An international team of astronomers has witnessed a rare dynamic event foreshadowing the death of a red giant star for the first time – a discovery that reinforces predictions about our Sun's ultimate demise.

Caught in the act: Images capture molecular motions in real time

Researchers have used ultra-high-speed X-ray pulses to make a high-resolution "movie" of a molecule undergoing structural motions. The research, published in Nature Chemistry, reveals the dynamics of the processes in unprecedented ...
