NASA and the European Space Agency's Hubble Space Telescope has been in low Earth orbit for nearly 28 years, but with several repairs and upgrades over the decades it's still sending back beautiful images. Just a few days ago, the ESA released this Hubble image of a pair of barred spiral galaxies some 350 million light years away in the process of merging, their two galactic nuclei still separated by a massive distance but throwing out clouds of hot gas and mid-formation stars.
