The newly discovered "blazar," which has a mass equal to 700 million suns, is the oldest of its kind ever seen and changes what we know about the early universe.

Electromagnetic radiation is carried by photons, massless particles that travel at the speed of light (300,000 kilometers per second in a vacuum). Every photon is characterized by wavelength (the ...

Philip Morrison and Guiseppe Cocconi analyzed how two civilizations separated by many light years of space might use electromagnetic radiation to communicate. Electromagnetic radiation is the general ...

Jupiter's Great Red Spot storm, which usually appears dark-red, can be seen shining a lurid blue color in an ultraviolet image of the planet.

It’s notoriously difficult to predict when the sun will belch out a large solar flare — an explosive burst of radiation that ...
