哈勃太空望远镜
It's estimated that roughly two-thirds of the spiral galaxies in our universe contain a bar of stars at their centers. That includes our home galaxy, the Milky Way, and the galaxy pictured in this 2016 Hubble image: IC 5201. This galaxy resides 40 million light-years away in the southern constellation Grus (The Crane), and was originally discovered in 1900 at the Cape Town Observatory by astronomer Joseph Lunt. Hubble's Advanced Camera for Surveys resolves individual stars in the galaxy, allowing astronomers to learn more about how stars form, evolve, and die throughout our universe. Image description: A hazy, yellow bar of stars sits at the center of a faint spiral galaxy. Several stars are visible throughout, along with small patches of bright blue star formation.
