highest-energy cosmic rays have extragalactic origin




cosmic rays are atomic nuclei that travel through space at speeds close to that of light. low-energy cosmic rays come from the sun or from our own galaxy, but the origin of the highest-energy particles has been the subject of debate ever since they were first discovered fifty years ago: do they come...



new for three types of extreme-energy space particles: theory shows unified orig




this image illustrates the 'multi-messenger' emission from a gigantic reservoir of cosmic rays that are accelerated by powerful jets from a supermassive black hole. the high-energy cosmic rays escaping from the black hole's active galactic nucleus are trapped in the magnetized environment that serve...



we still don’t know where cosmic rays are coming from




enlarge/ the fermi space telescope. nasashare this storyhigh energy cosmic rays are something of a conundrum wrapped in an enigma. essentially, they can't come from very far away and still have the energy they possess. to that end, cosmic rays should originate from within the milky way. yet, they s...

space-based experiment will tackle the mysteries of cosmic rays




on august 14, 2017, a groundbreaking university of maryland-designed cosmic ray detector will travel to the international space station (iss) aboard the spacex-12 commercial resupply service mission. the instrument, named iss cosmic ray energetics and mass (iss-cream), is roughly the size of a refri...



research to advance disease therapies, understand cosmic rays among cargo headed

scientists trace the origin of high-energy cosmic radiation




cosmic rays are energetic particles radiation that travel at nearly the speed of light and bombard the earth. we know they originate outside our galaxy, but because they are deflected along the way, it's been impossible to trace their source. it's a puzzle scientists have been trying to solve since ...



nustar mission proves superstar eta carinae shoots cosmic rays




a new study using data from nasa's nustar space telescope suggests that eta carinae, the most luminous and massive stellar system within 10,000 light-years, is accelerating particles to high energies—some of which may reach earth as cosmic rays.

supertiger balloon flies again to study heavy cosmic particles




a science team in antarctica is preparing to loft a balloon-borne instrument to collect information on cosmic rays, high-energy particles from beyond the solar system that enter earth's atmosphere every moment of every day. the instrument, called the super trans-iron galactic element recorder (super...

plasma from lasers can shed light on cosmic rays, solar eruptions




lasers that generate plasma can provide insight into bursts of subatomic particles that occur in deep space, scientists have found. such findings could help scientists understand cosmic rays, solar flares and solar eruptions—emissions from the sun that can disrupt cell phone service and knock out ...



nustar mission proves superstar eta carinae shoots cosmic rays




eta carinae's great eruption in the 1840s created the billowing homunculus nebula, imaged here by hubble. now about a light-year long, the expanding cloud contains enough material to make at least 10 copies of our sun. astronomers cannot yet explain what caused this eruption. credit: nasa, esa, and ...

the universe's most energetic particles have traveled a long way




over a period of twelve years, scientists used the pierre auger observatory, which consists of telescopes and particle detectors deployed over an area in western argentina larger than the state of rhode island, to collect readings on cosmic rays' origins. they discovered that most of the particles c...
