Target Details

This galaxy resides roughly 106 million light years away, behind the constellation Aries. It is twice the size of our Milky Way, spanning around 200,000 light years! UGC 1466 is catalogued as an unbarred spiral galaxy and was first discovered on the 29th of November, 1785, by astronomer William Herschel.

It is also listed in a catalogue of peculiar galaxies as Arp 78. These galaxies are often in some state of collision, which causes features such as tidal streams or far-flung and very faint patches of stars that have been ejected from the main disc as a result of gravitational forces during collision.

Wait, what exactly is a galaxy in the first place? Well, they are essentially the largest “building blocks” of the universe. They contain everything that is smaller than them, from nebulae to stars, planets, moons, comets—you name it, it likely resides within a galaxy.
