Hubble's false colours show a massive star forming in infrared light
Hubble's image of IRAS 16562-3959, a star-forming region in the Milky Way about 5,900 light-years away in Scorpius, is coloured by artists rather than by eye. Hubble's raw observations are always black and white, and the data here were collected through four infrared filters that the human eye cannot see. Image specialists assign colours that follow the usual pattern, with shorter wavelengths shown as bluer and longer ones as redder. The centre hosts a forming star thought to be about 30 times the mass of the Sun, hidden by dust. Near-infrared light escapes on two sides, where a powerful jet from the young star has cleared the dust.
False colour is how invisible light becomes visible, and it carries real data about wavelengths, not just decoration. Studying young massive stars this way helps explain how the brightest stars in the galaxy are born.
