Though stars and galaxies fill our night sky, most of the matter in the universe resides in the dark voids in between. Spread out over unfathomable distances, this cold, diffuse gas between galaxies—called the intergalactic ...
In 2016, scientists at Goddard Space Flight Center (GSFC) produced mirrors with the highest reflectance ever reported in the farultraviolet (FUV) spectral range (100-200 nm). To develop these mirrors, the team developed a ...
When the total solar eclipse swept across the United States on Aug. 21, 2017, NASA satellites captured a diverse set of images from space. But days before the eclipse, some NASA satellites also enabled scientists to predict ...
You don't have to wait on the next eclipse for another cool opportunity to look at the sun—our nearest star puts on quite the show of its own without the help of the moon. Heliophysics, the field of study devoted to the sun ...
NASA's biggest, most ambitious missions may cost billions - but they're well worth it, according to a report published Thursday.
NASA has selected six astrophysics Explorers Program proposals for concept studies. The proposed missions would study gamma-ray and X-ray emissions from clusters of galaxies and neutron star systems, as well as infrared ...
A century-old technology that scientists use to probe the ionosphere—the important atmospheric layer that can interfere with the transmission of radio waves—is getting smaller.
NASA has selected nine proposals under its Explorers Program that will return transformational science about the sun and space environment and fill science gaps between the agency's larger missions; eight for focused scientific ...
NASA scientists and engineers named their new CubeSat after the mythological Norse god of the dawn. Now, just days from launch, they are confident Dellingr will live up to its name and inaugurate a new era for scientists ...
NASA has selected Southwest Research Institute (SwRI) to further develop the concept for a small satellite mission to image the Sun's outer corona. SwRI's "Polarimeter to Unify the Corona and Heliosphere" (PUNCH) program ...
