Recent airborne science flights to Greenland are improving NASA’s understanding of space weather by measuring radiation exposure to air travelers and validating global radiation maps used in flight ...

A research paper described a region between Earth and the Moon where cosmic rays are deflected by our planet's magnetic field.

Galactic cosmic rays (GCRs) are mostly absorbed by Earth's atmosphere before they can reach the surface. However, they pose a ...

Because cosmic ray particles are electrically charged, they change course when they encounter magnetic fields. This means scientists can’t trace them back to their sources. Gamma rays, however, travel ...

Add Yahoo as a preferred source to see more of our stories on Google. A composite image of X-ray, radio, and optical light data from the "cosmic hand" nebula leaves open questions about the ...

A new study from NASA reveals that a supernova observed nearly two millennia ago expanded inside a pre-formed cosmic cavity, offering strong evidence about the type of stellar explosion that created ...

Toyota's annus horribilis can be traced, in part, to a rash of incidents where Toyota vehicles accelerated by themselves, causing drivers to lose control and crash. More than 100 deaths have been ...

The sun, a searing hot sphere of gas primarily composed of hydrogen and helium, boasts surface and outer atmospheric temperatures ranging from 10,000 to 3.6 million degrees Fahrenheit on its surface ...

But before an expensive mission such as this can be launched, the technology employed in it needs to be tested. Scheduled for ...

NASA has unveiled a breathtaking new image showing what appears to be a massive “cosmic hand” stretching across 150 light-years of space, created by one of the galaxy’s most powerful electromagnetic ...

The ‘guest star’ of 185 AD has been one of astronomy's most unresolved cases for over 1800 years. Ancient Chinese chroniclers recorded a mysterious li.

(Phys.org)—During a powerful solar blast on March 7, NASA's Fermi Gamma-ray Space Telescope detected the highest-energy light ever associated with an eruption on the sun. The discovery heralds Fermi's ...
