The National Geospatial-Intelligence Agency and National Reconnaissance Office are eager to compare their near-term needs with the capabilities of companies that obtain data from small satellites or have innovative ways of using space-based data to make sense of activity on the ground. “It comes down to change and activity,” Kevin […]
Gravity governs the movements of the cosmos. It draws flocks of galaxies together to form small groups and more massive galaxy clusters, and brings duos so close that they begin to tug at one another. This latter scenario can have extreme consequences, with members of interacting pairs of galaxies often […]
More than 12 million people sat in the path of totality of the August 21 solar eclipse, as it passed from the West Coast to the East Coast of the United States. The spectacular miracle of nature saw the moon cross paths with the sun, blocking out sunlight and darkening […]
Cassini gazes across the icy rings of Saturn toward the icy moon Tethys, whose night side is illuminated by Saturnshine, or sunlight reflected by the planet.
Asteroid Florence, a large near-Earth asteroid, will pass safely by Earth on Sept. 1, 2017, at a distance of about 4.4 million miles, (7.0 million kilometers, or about 18 Earth-Moon distances).
Dim objects called brown dwarfs, less massive than the Sun but more massive than Jupiter, have powerful winds and clouds — specifically, hot patchy clouds made of iron droplets and silicate dust. Scientists recently realized these giant clouds can move and thicken or thin surprisingly rapidly, in less than an […]
Your dollars go a lot further in some states than others. The Tax Foundation released the latest iteration of its map showing the relative value of $100 in every state compared with the national average using data from the Bureau of Economic Analysis. In more expensive states like California, you can afford […]
