James Webb Telescope: How the Infrared Observatory Works
The James Webb Space Telescope uses gold-coated beryllium mirrors, a tennis-court-sized sunshield, and cryogenic instruments at L2 to uncover early galaxies and study exoplanets.
OLED Vs QLED: How Panel Contrast and Brightness Differ
Comparing OLED and QLED displays reveals distinct engineering approaches, contrasting self-lit organic pixels with backlit quantum dot panels across brightness, contrast, and longevity.
NASA CASALS Instrument Maps 3D Landscapes Without Moving Mirrors
NASA engineers at Goddard Space Flight Center tested CASALS, an airborne lidar system that steers laser pulses by wavelength to eliminate gaps between orbital tracks.
SpaceX Falcon 9 Launch Creates a Glowing Space Jellyfish
A predawn SpaceX Falcon 9 rocket launch from Cape Canaveral illuminated high-altitude exhaust plumes, creating a glowing space jellyfish cloud visible along the US East Coast.
Diamond Defects Shift Under UV Laser Pulses Without Qubit Loss
Researchers used nanosecond ultraviolet laser pulses to modify carbon defects in diamond while leaving sensitive nitrogen-vacancy quantum sensors intact.
Carson Bruns Tests Invisible Tattoo Ink Under UV Light
Nanoscientist Carson Bruns and his team at the University of Colorado Boulder have developed an invisible tattoo ink that appears under ultraviolet light and disappears under visible light.
Why the LISA Mission Relies on All-Glass Test Telescopes
NASA has partnered with L3Harris Technologies to build an all-glass test telescope for the LISA mission, a space observatory designed to detect ripples in spacetime.
Thorium Nuclear Clocks Tick for the First Time in Lab Trials
Researchers in Vienna and Beijing have built the first working nuclear clocks by exciting thorium-229 nuclei with ultraviolet lasers, opening a new era of precision metrology.
Shropshire Astronomers Win Approval for Mini-Observatory
Amateur astronomers from the Shropshire Astronomical Society have gained planning permission to erect a mini-observatory dome at Rodington Village Hall, illustrating the zoning rules and structural permits required to establish permanent stargazing stations.
How Pressure Sensitive Paint Maps Dynamic Wing Airflow
NASA researchers at Langley Research Center demonstrated unsteady pressure sensitive paint on a freely moving Benchmark Supercritical Wing model inside the low-oxygen Transonic Dynamics Tunnel.
