Voyager 1 Continues Its Journey
2013-03-20 14:16:43

Lee Rannals for redOrbit.com - Your Universe Online NASA´s Voyager 1 spacecraft may have allegedly left the confines of our solar System after 35 years and more than 11 billion miles of traveling through space. Scientists writing in the Geophysical Research Letters claim that they measured drastic changes in radiation levels on August 25, 2012 while the spacecraft was sitting over 11 billion miles away from the Sun. The anomalous cosmic rays (those trapped in the outer heliosphere)...

Supernova Gives Scientists Clues Into Origins Of Cosmic Rays
2013-02-14 13:19:29

[ Watch the Video: Fermi Proves Supernova Remnants Produce Cosmic Rays ] Lee Rannals for redOrbit.com - Your Universe Online A thousand-year-old supernova has given the European Space Observatory's Very Large Telescope (VLT) ample opportunity to gain some clues about the origins of cosmic rays. The new observations, reported in the journal Science today, suggest the presence of fast-moving particles in the supernova remnant. Over a thousand years ago, in 1006 AD, a new star was...

It spent 55 days, 1 hour, and 34 minutes aloft at 127,000...

Black Hole Radiation Blasted Earth During 8th Century
2013-01-21 11:56:25

Lee Rannals for redOrbit.com - Your Universe Online According to a new study, black hole cosmic radiation blasted into the Earth back in the 8th century. Japanese astrophysicist Fusa Miyake discovered last year clues for the strange event located in the rings of ancient cedar trees that dated back to either 774 or 775 AD. Researchers teamed together to determine what had caused the surge in carbon-14 in the rings and found no evidence of a supernova, as they had expected. The...

Scientists Deduce Contents Of Cosmic Mystery Box
2013-01-01 10:16:02

April Flowers for redOrbit.com - Your Universe Online Science teachers in grade school sometimes hand out "mystery boxes," which contain ramps, barriers and a loose marble. Rotating the marble and feeling it hang up or drop, the students begin to deduce the contents of the box. Scientists who are trying to understand why tiny particles rain down from space face a similar dilemma, but on a much grander scale. Their mystery box is a hundred thousand light years across, and the only clues...

Cosmic Rays Help Diagnose Nuclear Reactors

Brett Smith for redOrbit.com - Your Universe Online They may not be using alien technology, but physicists from Los Alamos National Laboratory are looking to outer space for help in diagnosing a damaged nuclear reactors like the one that caused massive evacuations around the Fukushima Daiichi plant in March 2011. According to their report in the journal Physical Letters, the research team from Los Alamos National Laboratory has found a way to use cosmic ray radiation to...

Voyager 1 Celebrates 35th Anniversary, About To Cross Threshold Into Interstellar Space
2012-09-05 09:57:27

[WATCH VIDEO] Lawrence LeBlond for redOrbit.com - Your Universe Online Celebrating its 35th anniversary in space today, NASA´s Voyager 1 spacecraft is about to cross the threshold of our solar system, to boldly go where no man, nor machine, has ever gone before. While it is difficult to pinpoint the exact moment when the American space company´s premier long distance journeyer will cross the boundary of the heliosphere, expert measurements have indicated that it is very close....

Voyager 1 Nearing Interstellar Space
2012-08-05 06:27:51

[ Watch the Video: Voyager 1 at the Final Frontier ] redOrbit Staff & Wire Reports - Your Universe Online The levels of high-energy cosmic rays originating from outside our solar system and the levels of lower-energy particles originating from within have been undergoing changes at a faster rate than at any other time in the past seven years, NASA officials announced on Friday. Citing data obtained from the Voyager 1 spacecraft, the US space agency revealed that there was a...

Voyager 1 Entering Interstellar Space
2012-06-15 13:52:45

Lee Rannals for redOrbit.com After several decades of making a lonely journey across our solar system, Voyager 1 has signaled to NASA that it may have reached the edge of interstellar space. The spacecraft, which launched in 1977, is now roughly 11 billion miles away and traveling at 6 miles per second. NASA said it takes Voyager 1's data 16 hours and 38 minutes to reach the antennas of its Deep Space Network on Earth. Data from the spacecraft indicates that the 34-year-old...

The IceCube Neutrino Observatory is a neutrino telescope that is currently being built at the Amundsen-Scott South Pole Station. IceCube is being constructed in deep Antarctic ice by deploying thousands of PMTs (photomultiplier tubes) at depths of 4750 to 8000 feet. These spherical optical sensors are deployed on strings of sixty modules each, into holes melted by hot water drilling. Since 2005, 59 strings have been deployed and installation is expected to be complete by 2011. The strings are...

Gamma-Ray Astronomy -- Gamma-ray astronomy is the astronomical study of gamma rays. Long before experiments could detect gamma rays emitted by cosmic sources, scientists had known that the universe should be producing these photons. Work by Feenberg and Primakoff in 1948, Hayakawa and Hutchinson in 1952, and, especially, Morrison in 1958 had led scientists to believe that a number of different processes which were occurring in the universe would result in gamma-ray emission. These...
