Astronomers have detected fast-repeating radio bursts from a distant "dead" galaxy that should not contain the energy to produce these types of signals.

The universe tells us its story mainly through light and other wavelengths of electromagnetic radiation ... deeper and deeper into the Milky Way Galaxy (the island of stars in which we live ...

The electromagnetic spectrum consists of a group of radiations that all travel at the speed of light (\(3\times 10^{8},m\,s^{-1}\)). In the middle of the EM spectrum is the visible spectrum ...
