Science Alert: If you look just to the right of the northern constellation of Triangulum, you’ll see a faint smudge in the night sky. That’s the Triangulum Galaxy, and it’s 3 million light-years away – one of the most distant objects visible to the naked eye.
But the Hubble Space Telescope’s eyes are not as limited as our human eyes, and it’s managed to take the most detailed image yet of our Local Group neighbour.
How detailed? Well, the thing is absolutely huge, made up of 54 separate images stitched together. It clocks in at 665 million pixels (a 1.67GB TIFF), showing a region 19,400 light-years across, with 10-15 million individual stars visible.
