radio astronomy

There had been a lot of radio astronomy data to suggest flat rotation curves, but because radio astronomy was very new, it was really only once you saw it with the eye that the astronomy community was convinced.

In contrast, the best-known frequency in radio astronomy, emitted by hydrogen atoms in space, is 1,420 MHz, a wavelength of 21 centimeters.

The procedure is relatively easy in radio astronomy, both because radio-emitting objects tend to be extremely bright, and because radio waves are relatively large and thus easy to line up.

This sharpness is often a key goal in astronomy, as it allows us to pinpoint individual stars in faraway galaxies or map the precise shape of a nebula, and the long wavelengths of radio astronomy offer a different way of building big telescopes.

The science of radio astronomy is thrilling, but the telescopes look decidedly odd to anyone accustomed to the shiny mirrored telescopes they’ve peered through.

He also knew of the growing importance of radio astronomy, but he hadn't known the Egyptians were in on it.

Radio astronomy is no longer about the stars seen through human eyes.

Admittedly, he didn't have much knowledge of astrophysics or radio astronomy.
