Centaurus, the Centaur, is one of the most striking constellations in the southern sky. The lovely Milky Way flows through this large constellation whose celestial wonders also include the closest star to the sun, Alpha Centauri, the largest globular star cluster in our galaxy, Omega Centauri, and the closest active galaxy, Centaurus A.

Nearby Spiral Galaxy NGC 4945

A bevy of black holes and neutron stars shine as bright, point-like sources against bubbles of million degree gas in this false-color x-ray image from the orbiting Chandra Observatory. The striking picture shows...

APOD: 2026 February 4 Б Spiral Galaxy NGC 1512: Wide Field
4.02.2026

Most galaxies don't have any rings -- why does this galaxy have three? To begin, a ring that's near NGC 1512's center -- and so hard to see here -- is the nuclear ring which glows brightly with recently formed stars.

Nearby Spiral Galaxy NGC 4945
12.04.1999

For such a close galaxy, NGC 4945 is easy to miss. NGC 4945 is a spiral galaxy in the Centaurus Group of galaxies, located only six times farther away than the prominent Andromeda Galaxy. The thin disk galaxy is oriented nearly edge-on, however, and shrouded in dark dust.

M51: The Whirlpool Galaxy in Dust and Stars
19.02.2006

The Whirlpool Galaxy is a classic spiral galaxy. At only 30 million light years distant and fully 60 thousand light years across, M51, also known as NGC 5194, is one of the brightest and most picturesque galaxies on the sky.

The Whirlpool Galaxy and Beyond
6.09.2016

Follow the handle of the Big Dipper away from the dipper's bowl, until you get to the handle's last bright star. Then, just slide your telescope a little south and west and you might find this stunning pair of interacting galaxies, the 51st entry in Charles Messier's famous catalog.
