The sharpest view ever of the Triangulum Galaxy: 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.

NGC 604 — a gigantic gas cloud in the Triangulum Galaxy: This image shows NGC 604, located within the Triangulum Galaxy. Some 1500 light-years across, this is one of the largest, brightest concentrations of ionised hydrogen (H II) in our Local Group of galaxies, and it is a major centre of star formation. The gas in NGC 604, around nine-tenths of which is hydrogen, is gradually collapsing under the force of gravity to create new stars. Once these stars have formed, the energetic ultraviolet radiation they emit excites the remaining gas in the cloud. This image is only a tiny part of the large wide-field image of the Triangulum Galaxy created by the NASA/ESA Hubble Space Telescope. Hubble has observed this object before, with different cameras: In 2003, using the WFPC2 and in 2010, using the ACS. The different colours in the images have their origin in the different filters being used.
