Attosecond flashes of light and x-rays take snapshots of fleeting electrons in solids. Credit: MPQ, Attoelectronics Group A team of scientists at the Max Planck Institute of Quantum Optics, Garching, Germany has been able to capture the dynamics of core-excitons in solids in real-time. Using ultrafast flashes of laser and x-ray radiation, scientists at the

Scanning electron micrograph of a polymeric WGM split-disk cavity: Two opposing half-disks (R=25?m) with an intermediate air gap of several microns are structured onto an elastomeric PDMS substrate with direct laser writing.

A black hole captured by a neutron star.

Two papers on their work were published in the journal

The cosmic velocity web is represented by surfaces of knots in red and surfaces of filaments in gray. The black lines with arrows illustrate local velocity flows within filaments and toward knots. The Laniakea Supercluster basin of attraction that includes our Milky Way galaxy is represented by a blue surface. The region being displayed extends

How would an alien world like this look? That’s the question that ASU undergraduate art major Joshua Gonzalez attempted to answer. He worked with Professor Patrick Young’s group to learn how to analyze stellar spectra to find chemical abundances, and inspired by the scientific results, he created two digital paintings of possible unusual extrasolar planets,

As the late Carl Sagan once put it: “The nitrogen in our DNA, the calcium

University of Central Florida Professor Zenghu Chang broke the record for the fastest light pulse. Credit: University of Central Florida A research team at the University of Central Florida has demonstrated the fastest light pulse ever developed, a 53-attosecond X-ray flash The group led by Professor Zenghu Chang beat its own record set in 2012:

The NOvA detector measures 50 feet by 50 feet by 200 feet, and the top surface of the detector as shown here is covered with readout and monitoring systems. Each gold-colored box in the image contains a photodiode array, cooling components, and associated electronics to detect light from 32 of the 344,000 cells that make
