X-rays bouncing off of dust clouds surrounding the erupting neutron star Circinus X-1 let astrophysicists work out the star’s position. NASA's Chandra X-ray Observatory and ESA's XMM-Newton had been tasked to examine the X-ray source.

Auroras reached as far south as Philadelphia yesterday (June 22) after a massive burst of particles was ejected from the sun and pummeled Earth's atmosphere. This strong solar storm continues to rage, and auroras are expected be visible again tonight.
23 June 2015, 09:06 AM ET
Images captured between May 29th and June 18th, 2015 resolve patches on the icy dwarf's surface and suggest that one of Charon’s poles might be significantly less bright than the bulk of the moon.
