Every 20 years or so, the red giant star dumps enough hydrogen gas onto its companion white dwarf star to set off a brilliant thermonuclear explosion on the white dwarf‘s surface. At about 5,000 light years distant, the resulting nova explosions cause the RS … Read more

Cosmic Lens Flare By ESA

Cosmic Lens Flare By ESA, Astronomy news

The centre of this image from the NASA/ESA Hubble Space Telescope is framed by the tell-tale arcs that result from strong gravitational lensing, a striking astronomical phenomenon which can warp, magnify, or even duplicate the appearance of distant galaxies. Gravitational lensing occurs when light from a distant galaxy is subtly distorted by the gravitational pull … Read more
