The Hubble Space Telescope notices a galaxy – and is not alone



  Spiral Galaxy NGC 1706

Galaxies may look lonely, floating alone in the vast, inky blackness of sparsely populated space. appearance may be misleading. This image of NGC 1

706 taken by NASA / ESA Hubble Space Telescope is a good example of this. NGC 1706 is a spiral galaxy located approximately 230 million light-years away in the constellation Dorado (Swordfish).

NGC 1706 is known to belong to something known as a galactic group, which is just as the name suggests – a group of up to 50 galaxies that are gravitationally linked and therefore relatively close to one another. About half of the galaxies we know in the universe belong to some group, which makes them incredibly common cosmic structures. Our home galaxy, the Milky Way belongs to the Local Group, which also contains the Andromeda Galaxy, the Large and Small Magellanic Clouds, and the Triangular Galaxy.

The groups are the smallest of the galactic assemblages; others are clusters that can consist of hundreds of thousands of gravity-free galaxies and subsequent superclusters that unite multiple clusters together.
