Galaxy clusters are the largest gravitationally bound structures in the universe, with each containing hundreds or even ...

Radio astronomy opened up the universe for scientists. They could map new elements across galaxies and also search for ...

As humans began to explore outer space in the latter half of the 20th century, radio waves proved a powerful tool. Scientists could send out radio waves to communicate with satellites, rockets and ...

Created using data from two extensive surveys, this spectacular radio image of the galactic plane of the Milky Way provides valuable insights into the birth and death of stars.

Due to the audio medium of radio, we tend to associate radio waves with sound, but they are a type of light. Just like we can see different colors due to different wavelengths of visible light, we can ...

In the global game of nuclear brinksmanship, secrets are the coin of the realm. This was especially true during the Cold War, ...

The European Research Council (ERC) has agreed to fund two high-profile international projects with ETH's backing. Markus ...

In a groundbreaking discovery, astronomers atSouth Africa’s MeerKAT radio telescope detected the first radio signal from the ...

Researchers propose that hydrogen gas from the early Universe emitted detectable radio waves influenced by dark matter. Studying these signals, especially from the Moon’s radio-quiet environment, ...

Astronomers searching for signs of life beyond Earth have spotted something strange. An as-yet unexplained radio signal appears to be coming from the direction of the star closest to the sun—a small ...

Sound vibrations leave the singer's mouth. The higher the pitch of the sound, the higher the frequency, or number of vibrations in a given amount of time. The sound enters the microphone, where it is ...

FM radio works the same way that AM radio works. The difference is in how the carrier wave is modulated, or altered. With AM radio, the amplitude, or overall strength, of the signal is varied to ...
