How do you photograph a galaxy that stretches for thousands of light-years? One @NASAHubble Space Telescope image at a time.

This portrait of the Triangulum galaxy was stitched together from 54 Hubble images and spans an area 14,500 light-years across — making it the largest high-resolution image of Triangulum ever assembled.

Triangulum is the junior member of a trio of spiral galaxies, which includes ours (the Milky Way) and Andromeda. Compared to other recorded galaxies, Triangulum has a very neat and tidy spiral. The dust is evenly distributed throughout. Astronomers suspect that Triangulum’s tidiness is a result of having successfully avoided disruptive interactions with other galaxies.
How many stars are burning in this capture of Triangulum? Nearly 25 million. Striking areas of star birth glow bright blue throughout the galaxy, particularly in beautiful nebulas of hot ionized hydrogen gas.
Astronomers have only just begun to mine the enormous amount of data generated by these new Hubble observations, which will yield important insights into the process of star formation.
