Hubble Captures Galactic Glamour Shot

This stunning image by the NASA/ESA Hubble Space Telescope features the spiral galaxy NGC 5643 in the constellation of Lupus (the Wolf). Looking this good isn’t easy; 30 different exposures, for a total of nine hours of observation time, together with the high resolution and clarity of Hubble, were needed to produce an image of such high level of detail and beauty.

NGC 5643 is about 60 million light-years away from Earth and has been the host of a recent supernova event (not visible in this latest image). This supernova (2017cbv) was a specific type in which a white dwarf steals so much mass from a companion star that it becomes unstable and explodes. The explosion releases significant amounts of energy and lights up that part of the galaxy.

The observation was proposed by Adam Riess, who (alongside Saul Perlmutter and Brian Schmidt) was awarded a Nobel Prize in physics in 2011 for his contributions to the discovery of the accelerating expansion of the universe.

Don`t worry there is no significant man- made global warming. The global warming scare is not driven by science but driven by politics. Al Gore and the UN are dead wrong on climate fears. The IPCC process is a perversion of science. View all posts by uwe.roland.gross
