Since 1958, NASA has launched dozens of satellites to monitor Earth. While Explorer 1 measured cosmic rays, satellites today can observe everything from salinity in the oceans to nitrous oxide, air temperature, and more. Over two dozen active NASA satellite missions currently monitor Earth from or...
X-rays and gamma-rays detected by these balloons are “secondary cosmic rays,” produced by the crash of primary cosmic rays into Earth’s upper atmosphere. They trace radiation percolating down toward our planet’s surface. The energy range of the sensors, 10 keV to 20 MeV, is similar to...
As well as looking like pretty lights adorning the Christmas tree, the stars picked out by Chandra are young and volatile, giving off flares of energy including X-rays. They show variations in their outputs, due to factors like magnetic fields and flares, which makes them appear to twinkle. ...
The military can be the former; strangely enough IT can be both...the military won't focus on cosmic rays is my guess. I have plans for biolistics to spin off directed gene knockouts focusing charged radiation rays. Without going for the ion engine in the 1970s and particle imaging tech...
A spectrometer will analyze the gamma rays and neutrons produced when Psyche is struck by cosmic rays. 光谱仪将会分析灵神星在宇宙射线照射下所产生的伽玛射线和中子。 Each element in the periodic table releases gamma rays of specific wavelengths, 元素周期表内的每个元素都会释放特定波长的伽玛射线, so...
The Voyager craft, nearing a half-century of operation, may potentially return unprecedented science data through the mid-2030s, when theyexhaust their finite nuclear fuel supply. Yet out in interstellar space, another threat looms, too: harmful radiation called galactic cosmic rays. These high sp...
Sign up for Mashable's Light Speed newsletter today. In the future, spacecraft may rely upon these rapidly spinning objects, and the two jets shooting out from their poles, to navigate space — a realm without the comforts of GPS or the likes of Google Maps....

NASA’s Imaging X-ray Polarimetry Explorer (IXPE) mission is the first satellite dedicated to measuring the polarization of X-rays from a variety of cosmic sources, such as black holes and neutron stars. Credit: NASA Cassiopeia A is the shredded remains of a star that exploded several thousand...
