Where Do Cosmic Rays Come From?
2013-03-01 05:33:26

[ Listen to the Webcast ] John P. Millis, Ph.D. for redOrbit.com — Your Universe Online As we search the heavens, one of the striking observations is that we are constantly bombarded by a stream of extremely high energy charged particles, traveling at nearly the speed of light. Known as Cosmic Rays — composed mostly (90%) of protons with the rest mostly heavy nuclei and a small number of electrons — these particles appear to come from all directions. But where do...

Cosmic Radiation May Accelerate Onset Of Alzheimer's
2013-01-01 05:21:42

April Flowers for redOrbit.com - Your Universe Online Space travel is fraught with dangers for astronauts and equipment alike. A new study, led by the University of Rochester Medical Center, reveals that it may be much more dangerous than previously thought. The findings, published in the journal PLOS ONE, show that cosmic radiation — which would bombard astronauts on deep space missions — could accelerate the onset of Alzheimer's disease. "Galactic cosmic radiation poses a...

Moon And Martian Soil Could Shield Against Cosmic Radiation
2012-10-10 12:57:05

Lee Rannals for redOrbit.com - Your Universe Online The European Space Agency (ESA) is looking into how Moon and Martian soil could be used to help shield astronauts in space. ESA is teaming up with Germany's GSI particle accelerator for a two-year project in assessing promising materials for shielding future astronauts en route to the Moon, an asteroid or Mars. “We are working with the only facility in Europe capable of simulating the high-energy heavy atomic nuclei found in...

Cosmic Rays To Be Studied By University Of Utah
2012-09-26 12:06:39

April Flowers for redOrbit.com - Your Universe Online The University of Utah has plans to build a new observatory facility to study high energy cosmic rays, thanks to a $1 million grant from the W.M. Keck Foundation. These cosmic rays, which are 10 trillion times more energetic than particles emitted during a nuclear explosion, originate from violent cosmic events deep within the universe and hurtle their way towards Earth. The grant will allow a team of researchers to develop a new...

First Daredevil Stunt For Curiosity
2012-08-02 07:30:48

[ Watch The Video ] When Curiosity enters the Martian atmosphere on August 6th, setting in motion "the seven minutes of terror" that people around the world have anticipated since launch a year ago, the intrepid rover will actually be performing the mission's second daredevil stunt. The first was completed in July. For the past nine months, Curiosity has been acting as a stunt double for astronauts, exposing itself to the same cosmic radiation humans would experience following the...

Cosmic Ray Origins Still A Mystery
2012-08-01 05:01:58

April Flowers for redOrbit.com - Your Universe Online In August, physicists will gather to celebrate a century of research since the discovery of cosmic rays. It is widely accepted that cosmic rays are the nuclei of atoms, from the full array of naturally occurring elements that travel at near-light-speeds for millions of years before reaching Earth. What isn't known yet is where these cosmic rays originate. Alan Watson, emeritus professor of physics at the University of Leeds, provides...

Curiosity, The Astronaut Stunt Double
2012-02-25 05:28:49

[ Watch the Video ] With a pair of bug-eyes swiveling on a stalk nearly 8 feet off the ground, the 6-wheeled, 1800-lb Mars rover Curiosity doesn´t look much like a human being.  Yet, right now, the mini-Cooper-sized rover is playing the role of stunt double for NASA astronauts. “Curiosity is riding to Mars in the belly of a spacecraft, where an astronaut would be,” explains Don Hassler of the Southwest Research Institute in Boulder, Colorado.  “This...

Sun Delivered Curveball Of Powerful Radiation At Earth
2012-02-02 04:32:26

A potent follow-up solar flare, which occurred Friday (Jan. 27, 2012), just days after the Sun launched the biggest coronal mass ejection (CME) seen in nearly a decade, delivered a powerful radiation punch to Earth's magnetic field despite the fact that it was aimed away from our planet. According to University of New Hampshire scientists currently studying and modeling various aspects of solar radiation, this was due to both the existing population of energetic particles launched by the...

Curiosity And The Solar Storm
2011-12-15 04:46:44

On Nov. 26th, Curiosity blasted off from Cape Canaveral atop an Atlas 5 rocket.  Riding a plume of fire through the blue Florida sky, the car-sized rover began a nine month journey to search for signs of life Mars. Meanwhile, 93 million miles away, a second lesser-noticed Mars launch was underway.  Around the time that Curiosity´s rocket was breaking the bonds of Earth, a filament of magnetism erupted from the sun, hurling a billion-ton cloud of plasma (a “CME”)...

Image 1 - Fermi Shows That Tycho's Star Shines In Gamma Rays
2011-12-13 11:56:08

[ Watch the Video ] In early November 1572, observers on Earth witnessed the appearance of a "new star" in the constellation Cassiopeia, an event now recognized as the brightest naked-eye supernova in more than 400 years. It's often called "Tycho's supernova" after the great Danish astronomer Tycho Brahe, who gained renown for his extensive study of the object. Now, years of data collected by NASA's Fermi Gamma-Ray Space Telescope reveal that the shattered star's remains shine in...

Cosmic Rays -- Cosmic Rays. Cosmic rays are energetic particles that are found in space and filter through our atmosphere. Cosmic rays have interested scientists for many different reasons. They come from all directions in space, and the origination of many of these cosmic rays is unknown. Cosmic rays were originally discovered because of the ionozation they produce in our atmosphere. Cosmic rays also have an extreme energy range of incident particles, which have allowed physicists to...
