![]() ![]() Hubble's sharp view is giving researchers an updated weather report on the monster planet's turbulent atmosphere, including a remarkable new storm brewing, and a cousin of the Great Red Spot changing colour - again. This latest image of Jupiter, taken by the NASA/ESA Hubble Space Telescope on 25 August 2020, was captured when the planet was 653 million kilometres from Earth. Riess is a professor of astronomy and physics at Johns Hopkins University and a senior member of the science staff at the Space Telescope Science Institute, both in Baltimore. “No Earthly fireworks display can compete with this supernova, captured in its fading glory by the Hubble Space Telescope,” said Nobel Laureate Adam Riess in a statement. Hubble released a new time-lapse video Thursday that compresses this into a few seconds. Then, astronomers watched as the supernova faded away into nothing over nearly a year. This caused an excess of gas that served as the ignition for a thermonuclear explosion and effectively turning the white dwarf into an atomic bomb. It occurred after a white dwarf, or dead star, pulled material away from its companion star. The light from the explosion was even brighter than that of its host galaxy and the most radiant stars in the galaxy. The supernova released as much energy in days as our sun does over the timescale of several billion years, or the radiance from 5 billion suns. That means it has taken 70 million years for the light from this event to reach us, so we’re actually witnessing a supernova from the distant past. The supernova, dubbed SN 2018gv, was spotted in a spiral galaxy 70 million light-years away. Hubble in February 2018 began observing a supernova that was detected just a few weeks earlier by amateur astronomer Koichi Itagaki. Space Telescope Science Institut/STScI/ESA/Hubble & NASA, A. Over nearly a year, it faded away to nothing. This Hubble image of the NGC 2525 galaxy showcases a bright supernova toward the bottom left of the galaxy. ![]()
