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.
A team of international scientists, led by astronomers from Cardiff University, has shown for the first time that galaxies can change their structure over the course of their lifetime. The researchers have shown that a large proportion of galaxies have undergone a major ‘metamorphosis’ since they were initially formed after the Big Bang.
The bipolar star-forming region Sharpless 2-106 some 2,000 light-years away in the constellation Cygnus looks like a soaring, celestial snow angel in this image from the NASA/ESA Hubble Space Telescope. Twin lobes of super-hot gas, glowing blue in this image, stretch outward from the central young and massive star. This hot gas creates the “wings” of our angel.
