I spy with my little eye … a celestial eye? Our Hubble Space Telescope (@NASAHubble) spotted this brilliant cloud of colorful gas in the constellation of Centaurus, around 4,900 light-years from our home planet.
It’s distinctive eye-like shape, with a bright inner shell of gas and a more diffuse outer shell that extends far from the nebula, looks as if it could be the result of two separate ejections of gas. But this is in fact not the case: studies of the object suggest that they were formed at the same time, but are being blown from the star at different speeds. The powerful jets of gas emerging from the ends of the large structure are estimated to be shooting away from the star at speeds of up to 217,500 miles per hour.

By the standards of astronomical phenomena, planetary nebulas like this one are very short-lived, with a lifespan of just a few tens of thousands of years. Since launching our Hubble Space Telescope in 1990, our view of the universe and our place within it has never been the same.
