Look closely at this image from NASA’s Hubble Space Telescope and you’ll see galaxies of various shapes and sizes clustered together toward the center-left of the image. A few foreground stars shine brightly and are easily distinguished by the spikes that appear to extend outward from each star. These spikes, called diffraction spikes, are the […]

When people eventually head to the moon for long-term exploration and habitation, they’ll need equipment and spacesuits made of well-tested materials. That’s where NASA’s Lunar Environment Test Rig (LESTR) comes in handy. It simulates extreme cold lunar night conditions right here on Earth in a NASA Glenn lab, testing lunar-bound materials in temperatures ranging from […]

Sand clouds form every morning but clear up by nightfall on WASP-94A b, a well-studied gas giant in a constellation located nearly 700 light years away from Earth. Using data from the James Webb Space Telescope (JWST), research published in the journal Science is among the first to detect cloud cycles on a Hot Jupiter […]
