This 1995 Hubble Space Telescope image of the ‘Pillars of Creation’ is probably the most famous astronomical image of the 20th Century. Taken in visible light using a combination of SII/H-alpha and OIII filters, it shows a part of the Eagle Nebula where new stars are forming. The tallest pillar is around 4 light-years high

According to astronomers, the pillars which measure up to 4 light years in length were destroyed about 6,000 years ago by the shock wave from a supernova.

Since this is how long it takes to light to travel across such vast distances, we can currently see the shock waves approaching the pillars but we won't actually see their destruction for another thousand years or so!
