In the mid 1990s, when NASA built two identical Lightning Imaging Sensors (just in case), Dr. Hugh Christian planned all along to send the flight spare into space. He just didn't expect it to take almost 20 years for that to happen.

Researchers Pinpoint Watery Past on Mars

Researchers from Trinity College Dublin have discovered a patch of land in an ancient valley on Mars that appears to have been flooded by water in the not-too-distant past. In doing so, they have pinpointed a prime target to begin searching for past life forms on the Red Planet.

Extending VCSEL Wavelength Coverage to the Mid-Infrared

There are several important gases that are detectable with mid-infrared light, having wavelengths between 3-4 micrometers. Application-grade Vertical-cavity surface-emitting lasers (VCSELs), however, aren’t yet available for this wavelength range, but the increasing need for compact, portable and affordable gas sensors is spurring demand for energy-efficient semiconductor sources of mid-IR light. Addressing this demand, a group of researchers set out to develop a concept to extend the wavelength coverage of VCSELs into this important regime.

Turning Up the Heat for Perfect (Nano)Diamonds

For use in quantum sensing, the bulk nanodiamond crystal surrounding the point defect must be highly perfect. Any deviation from perfection will adversely affect the quantum behavior of the material. Highly perfect nanodiamonds are also quite expensive and difficult to make. A cheaper alternative, say researchers, is to take defect-ridden, low-quality, commercially manufactured diamonds, and then “heal” them. In APL Materials, they describe a method to heal diamond nanocrystals under high-temperature conditions.

Hubble Witnesses Massive Comet-Like Object Pollute Atmosphere of a White Dwarf

STSCI-H-p1709a-web-1200x900.jpg

Astronomers using NASA's Hubble Space Telescope have found the best evidence yet of the remains of a comet-like object scattered in the atmosphere of a white dwarf. The icy object, which has been ripped apart, is similar to Halley's Comet in chemical composition, but it is 100,000 times more massive.

Portable Superconductivity Systems for Small Motors

Superconductivity is one of modern physics’ most intriguing scientific discoveries. However, practical exploitation of superconductivity also presents many challenges. The challenges are perhaps greatest for researchers trying to integrate superconductivity in small, portable systems. Researchers demonstrate this week in Applied Physics Letters, that a portable superconducting magnetic system, which is, in essence, a high performance substitute for a conventional permanent magnet, can attain a 3-tesla level for the magnetic field.
