Check out this Amazing Picture of the Triangulum Galaxy by Hubble.

This gigantic image of the Triangulum Galaxy — also known as Messier 33 — is a composite of about 54 different pointings with Hubble’s Advanced Camera for Surveys. With a staggering size of 34 372 times 19 345 pixels, it is the second-largest image ever released by Hubble. It is only dwarfed by the image of the Andromeda Galaxy, released in 2015. The mosaic of the Triangulum Galaxy showcases the central region of the galaxy and its inner spiral arms. Millions of stars, hundreds of star clusters and bright nebulae are visible. This image is too large to be easily displayed at full resolution and is best appreciated using the zoom tool.

To the unaided eye, the Triangulum Galaxy is just a smudge in the night sky. But it’s a smudge that contains about 40 billion stars. It also contains some very active star-forming regions, which have attracted the eyes of astronomers.

The Triangulum has a couple other names: Messier 33 and NGC 598. But Triangulum is the easier name to remember. (It’s also sometimes called the “Pinwheel Galaxy.”) But whatever name you choose to call it, this Hubble image brings it to life.
