Swift, Chandra explore a youthful 'star wreck'
(Phys.org) —While performing an extensive X-ray survey of our galaxy's central regions, NASA's Swift satellite has uncovered the previously unknown remains of a shattered star. Designated G306.3.9 after ...
Physicists create first 'frequency comb' to probe ultraviolet wavelengths
Physicists at JILA have created the first "frequency comb" in the extreme ultraviolet band of the spectrum, high-energy light less than 100 nanometers (nm) in wavelength. Laser-generated frequency combs are the most accurate ...
Engineers make tiny, low-cost, terahertz imager chip
(Phys.org)—A secret agent is racing against time. He knows a bomb is nearby. He rounds a corner, spots a pile of suspicious boxes in the alleyway, and pulls out his cell phone. As he scans it over the packages, ...
Mysterious objects at the edge of the electromagnetic spectrum
The human eye is crucial to astronomy. Without the ability to see, the luminous universe of stars, planets and galaxies would be closed to us, unknown forever. Nevertheless, astronomers cannot shake their ...
Star Wars: What would hyperspace travel really look like?
The sight of the Millennium Falcon making the "jump to lightspeed" is one of the most iconic images from the Star Wars trilogy.
