This NASA/ESA Hubble Space Telescope image reveals a delicate blue group of stars — actually an irregular galaxy named IC 3583 — that sits some 30 million light-years away in the constellation of Virgo. This small galaxy is thought to be gravitationally interacting with one of its neighbours, the spiral Messier 90.
This galaxy, known as NGC 2337, resides 25 million light-years away in the high northern constellation of Lynx. NGC 2337 is an irregular galaxy, meaning that it lacks a distinct, symmetrical appearance. The galaxy was discovered in 1877 by the French astronomer Édouard Stephan who, in the same year, discovered the galactic group Stephan’s Quintet.
