Animation of a divergent biconcave lens, showing its effect on parallel rays of light. Light is refracted when it passes from air into the more dense medium of the glass lens, slowing it down and changing the angle of its path

Triangular prism splitting a ray of white light into its constituent colours.
This occurs because the light is refracted when it passes from the air to the glass, as the speed of light in glass is lower than that in air. Light with a shorter wavelength, at the blue end of the spectrum, is refracted more than the...

Tarantula nebula, optical image. Also known as 30 Doradus and NGC 2070, the Tarantula nebula is an emission nebula spanning nearly 1000 light years across.
Two bright clusters of stars are seen here. The star cluster R136 (centre) is only 2-3 million years old, and its hot young stars are ionising the hydrogen gas in the nebula, creating a red glow. Powerful winds from these stars sculpt...
