Let's visit the Boomerang Nebula! 🪃 This cosmic scene shows two lobes of gas and dust ejecting from a central star. Each lobe is about one light-year in length, which makes the total length of the nebula half as long as the distance from our Sun to our nearest stellar neighbors – the Alpha Centauri star system (about four light-years away). The Boomerang Nebula resides 5,000 light-years from Earth. Hubble's sharp vision resolves the intricate patterns and ripples within the nebula. Music credit
