Astronomers have now observed the radio emission from the neutral hydrogen gas (HI) in a nearby galaxy. Hydrogen gas emits radio emission in a spectral line at a very specific frequency of 1420 MHz.
The simplicity of a hydrogen atom makes it an ideal model for studying atomic structure and interactions. Yet, despite the ...
