Our galaxy's 'geysers' are towers of power
"Monster" outflows of charged particles from the centre of our Galaxy, stretching more than halfway across the sky, have been detected and mapped with CSIRO's 64-m Parkes radio telescope. Corresponding to the "Fermi Bubbles" ...

Fermi telescope finds gamma-ray galaxy surprises
Back in June 1991, just before the launch of NASA's Compton Gamma-Ray Observatory, astronomers knew of gamma rays from exactly one galaxy beyond our own. To their surprise and delight, the satellite captured similar emissions ...

Fermi Satellite clocks 'cannonball' pulsar speeding through space
Astronomers found a pulsar hurtling through space at nearly 2.5 million miles an hour—so fast it could travel the distance between Earth and the Moon in just 6 minutes. The discovery was made using NASA's Fermi Gamma-ray ...

Cosmic radiation causes fluctuations in global temperatures, but doesn't cause climate change
(Phys.org)—Unlike electromagnetic radiation, which consists of massless and accelerated charged particles, galactic cosmic rays (CR) are composed mostly of atomic nuclei and solitary electrons, objects that have mass. Cosmic ...
Did water-based life originate without water?
When trying to understand the origins of life on Earth, researchers run into a paradox: while water is an indispensable solvent for all known life forms that exist today, water also inhibits the formation of string-like chains ...
Are gamma ray bursts dangerous?
If comics have taught me anything, it's that gamma powered superheroes and villains are some of the most formidable around.

Cosmic 'spider' found to be source of powerful gamma-rays
Using the 4.1-meter SOAR Telescope in Chile, astronomers have discovered the first example of a binary system where a star in the process of becoming a white dwarf is orbiting a neutron star that has just finished turning ...

Mysterious gamma-ray emitting bubbles around the center of the Milky Way explained
A scientist from Tokyo Metropolitan University has shown that large gamma-ray-emitting bubbles around the center of the Milky Way were produced by fast, outward-blowing winds and an associated "reverse shock." Numerical simulations ...
