Astronomical objects that have a changing magnetic field can produce radio waves.
The radio astronomy instrument called WAVES on the WIND spacecraft recorded a day of bursts of radio waves from the Sun's corona and planets in our solar system..
Radio telescopes look toward the heavens to view planets, comets, giant clouds of gas and dust, stars, and galaxies.
By studying the radio waves originating from these sources, astronomers can learn about their composition, structure, and motion..
Much of the radio emission that comes from space is emitted by tiny electrically charged particles, known as electrons, moving through magnetic fields.
These electrons have usually been accelerated away from the shock waves of exploding stars, known as supernovae..
The signal's frequency of 1420 MHz is also part of a protected spectrum: a frequency range reserved for astronomical research in which terrestrial transmissions are forbidden, although a 2010 study documented several instances of terrestrial sources either interfering from adjacent frequency bands or illegally .

Radio astronomers study emissions from gas giant planets, blasts from the hearts of galaxies, or even precisely ticking signals from a dying star.
Today, radio astronomy is a major branch of astronomy and reveals otherwise-hidden characteristics of everything in the universe..
The study of radio propagation, how radio waves move in free space and over the surface of the Earth, is vitally important in the design of practical radio systems.
Radio waves passing through different environments experience reflection, refraction, polarization, diffraction, and absorption..
Property of waves that can oscillate with more than one orientation
