Have you ever wondered how astronomers manage to map out the Milky Way when it's so incredibly vast? One of the most powerful tools is something called 21 cm radiation. Hydrogen, the most abundant ...

Think of spin like a little arrow pointing up or down. Every so often, in the vast reaches of space, a hydrogen atom's ...

What do you get when you put a one-meter parabolic dish, an SDR, a Raspberry Pi, and an H1-LNA for 21 cm emissions together? The answer is: a radio telescope that can track hydrogen in the Milky Way ...

Astronomers from McGill University in Canada and the Indian Institute of Science (IISc) in Bengaluru have used data from the Giant Metrewave Radio Telescope (GMRT) in Pune to detect a radio signal ...

Radio Waves from Interstellar Hydrogen The thin clouds of hydrogen in space radiate energy at a frequency of 1420 megacycles and a wavelength of 21 centimeters. Astronomers use the phenomenon to ...

Every so often, in the vast reaches of space, a hydrogen atom's electron can flip its spin, going from a state where its spin is aligned with the proton to one pointing in the opposite direction. This ...
