This photo shows the Antenna galaxies, which started colliding 100 million years ago, creating millions of stars in the process which later exploded as supernovas. I really find it hard and sad to know that I'll never see this live.

But at least we have the telescopes to see it from here. The image of the galaxy—which is located 62 million light-years away from Earth—was created by mixing photos from three telescopes: The Chandra X-ray Observatory (the blue tones), the Hubble Space Telescope (gold and brown), and the Spitzer Space Telescope (red).
