Computer-coloured view of jet in M87 active galaxy
Jet in M87 galaxy. Coloured visible-light image of the core of the active galaxy M87. The core is upper left of centre, and a long optical jet is seen pointing toward lower right

Radio galaxy, computer artwork. A radio galaxy is a type of active galaxy, having a core of emission in the middle of the galaxy, known as an active galactic nucleus (AGN)

Artwork showing active galaxy Centaurus A
Artwork based on an optical photograph of the Centaurus A galaxy (NGC 5128). Centaurus As most distinctive feature is the great lane of dust (here appearing purple) which bisects the galaxy

Artwork of a black hole at the centre of a galaxy
Black hole. Artists impression of a large black hole (at lower centre) located at the centre of an active galaxy. Around the hole are numerous stars

Active galaxy, conceptual artwork
Active galaxy, conceptual computer artwork. Active galaxies are typical galaxies (centre), but with a small core of emission in the middle of the galaxy, known as an active galactic nucleus (AGN)

Active galaxy NGC 1275, gamma ray image
Active galaxy NGC 1275, Fermi Gamma-ray Space Telescope image. Brighter colours indicate higher numbers of gamma rays. The rays are thought to emanate from a central black hole

Active galactic nucleus, artwork
