>From the standpoint of a ham, the interesting point is that astronomers use this frequency to identify and observe far stars and galaxies. Since the frequency is a matter of particle physics it will be a constant throughout the universe. Therefore, any alien
astronomer will be using the same technique and will be monitoring that frequency. Any modulated signal or repetitive pattern of transmission (as opposed to random noise) that a ham could hear might be originating from an alien radio operator. I believe
the SETI people monitor 1,420 MHz for this very reason. Of course, the signal might be 10,000,000 years old or more, so you are unlikely to get a response if you reply.</div>

21-centimetre radiation, electromagnetic radiation of radio wavelength emitted by cold, neutral, interstellar hydrogen atoms. According to the rules of quantum mechanics, such atoms radiate their acquired energy in the form of low-energy photons that correspond
to a wavelength of 21 centimetres, or a frequency of 1,420 megahertz. This transition, called a hyperfine transition, occurs roughly every 10 million years. Although the transition occurs very rarely, there is so much hydrogen in the Milky Way Galaxy that
21-centimetre hydrogen emission is easily observable. The 21-centimetre radiation readily penetrates the clouds of interstellar dust particles that obstruct optical observations deep into the galactic centre and thus allows the mapping of the galaxy’s spiral
structure.</div>
