Humanity's farthest and longest-lived spacecraft, Voyager 1 and 2, achieve 40 years of operation and exploration this August and September. Despite their vast distance, they continue to communicate with NASA daily, still ...
More than 300 million people in the United States potentially could directly view the Aug. 21 total solar eclipse, and NASA wants everyone who will witness this celestial phenomenon to do so safely.
NASA's new Neutron star Interior Composition Explorer (NICER) mission to study the densest observable objects in the universe has begun science operations.
Deep in space between distant stars, space is not empty. Instead, there drifts vast clouds of neutral atoms and molecules, as well as charged plasma particles called the interstellar medium—that may, over millions of years, ...
NASA technologists produced telescope mirrors with the highest reflectance ever reported in the far-ultraviolet spectral range. Now, they're attempting to set another record.
Our Cold War history is now offering scientists a chance to better understand the complex space system that surrounds us. Space weather—which can include changes in Earth's magnetic environment—are usually triggered by the ...
A team of NASA scientists and engineers now believes it can leverage recent advances in a greenhouse-detecting instrument to build the world's first space-based sodium lidar to study Earth's poorly understood mesosphere.
Our sun is a chaotic place, simmering with magnetic energy and constantly spewing out particles. Sometimes the sun releases solar flares and coronal mass ejections—huge eruptions of charged particles—which contribute to space ...
After over 20 years of tests and development, NASA's Balloon Program team is on the cusp of expanding the envelope in high-altitude, heavylift ballooning with its super pressure balloon (SPB) technology. SMD technology investments ...
NASA has begun development of a mission to visit and study the sun closer than ever before. The unprecedented project, named Solar Probe Plus, is slated to launch no later than 2018.
