NASA Spinoffs for transportation
Charged with carrying the human race to frontiers distant and challenging, it only makes sense that NASA has had a profound impact on transportation. Since its founding in 1958, NASA’s pioneering research has advanced aeronautics and other modes of transportation as well. Through partnerships with private industry, NASA expertise and technologies developed for space travel are leading to …
Liftoff for ESA’s billion-star surveyor
ESA’s Gaia is destined to create the most accurate map yet of the Milky Way. By making accurate measurements of the positions and motions of 1% of the total population of roughly 100 billion stars, it will answer questions about the origin and evolution of our home Galaxy. The Gaia mission blasted off the morning …
Ghostly specter haunts ‘coldest place in universe’
At a cosmologically crisp one degree Kelvin (minus 458 degrees Fahrenheit), the Boomerang nebula is the coldest known object in the universe — colder, in fact, than the faint afterglow of the Big Bang, the explosive event that created the cosmos. Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope in Chile have taken a …

Europa likely off-kilter at one time
By analyzing the distinctive cracks lining the icy face of Europa, NASA scientists found evidence that this moon of Jupiter likely spun around a tilted axis at some point. Europa’s tilt could influence calculations of how much of the moon’s history is recorded in its frozen shell, how much heat is generated by tides in …
