The Hubble Space Telescope has discovered thousands of galaxies throughout its lifetime, but many of those galaxies are billions of light-years away, in the most distant parts of our visible universe. But the famed space telescope managed to find another galaxy recently. This one is a lot closer, and it was discovered completely by accident.
The researchers were studying a cluster of stars in our own galaxy called NGC 6752. This cluster lies around 13,000 light-years away, and scientists were studying the stars with Hubble to find out how old they are, and in turn, the age of the entire cluster.
