Cosmic space is filled with continuous, diffuse high-energy radiation. To find out how this energy is produced, the scientists behind ESA’s Integral gamma-ray observatory have tried an unusual method: ...

NEW ORLEANS — Astronomers using a NASA space telescope have discovered a region of the sky with a mysterious concentration of some of the universe's highest-energy radiation. The astronomers were ...

University of Oxford mathematical physicist Sir Roger Penrose won a Nobel Prize earlier this month for a lifetime of work studying black holes, singularities from which not even light can escape. Yet ...

Scientists have taken another step toward understanding dark energy by peering through a cosmic cloud of water vapor billions of light-years away from Earth. Dark energy is the name given to the ...

Full-Sky Map Of Cosmic Background Radiation, A Full-Sky Map Produced By The Wilkinson Microwave Anisotropy Probe (Wmap) Showing Cosmic Background Radiation, A Very Uniform Glow Of Microwaves Emitted ...

George Smoot, who won a Nobel Prize in Physics for his role in the "discovery of the blackbody form and anisotropy of the cosmic microwave background radiation” in 2006, has died at home at the age of ...

(via Sabine Hossenfelder) In the Big Bang Theory, the cosmic microwave background — microwave-range radiation that floats through the entire universe at a steady 2.7 Kelvin — is evidence that a hot ...

Bell Labs built a giant antenna in Holmdel, New Jersey, in 1960. It was part of a very early satellite transmission system called Echo. By collecting and amplifying weak radio signals bounced off ...

It is still a glimpse into the future: Astronauts could be put into artificial hibernation and in this state be better protected from cosmic radiation. At present, there are already promising ...
