A seemingly delicate bubble of gas photographed by the Hubble Space Telescope in 2006 captures the aftermath of a supernova in the Large Magellanic Cloud some 160,000 light years from Earth’s Milky Way. The remnants of the doomed star form a ring-like structure 23 light years across expanding through space at 18 million kilometres per hour (11 million mph). The remnant, known as SNR 0509, features ripples in the bubble’s surface that may be the result of density variations or collisions with debris from the original explosion. This image was captured by Hubble’s Advanced Camera for Surveys using a filter that isolates the glowing hydrogen in the expanding shell. Visible light images of the surrounding star field were taken by Hubble’s Wide Field Camera.
This NASA/ESA Hubble Space Telescope image reveals NGC 1222, a galaxy with a rather eventful story to tell. NGC 1222 has been described as a peculiar example of a so-called lenticular galaxy, but one that exhibits very recent star formation on a huge scale — an event known as a starburst — due to having recently consumed two dwarf galaxies.
This Hubble Space Telescope image shows globular cluster NGC 1783 in the Southern Hemisphere constellation of Dorado. NGC 1783 lies within the Large Magellanic Cloud, a satellite galaxy of our Milky Way, some 160,000 light-years from Earth. NGC 1783 is thought to be less than 1.5 billion years old — very young for a globular cluster.
