Record-breaking black hole outburst detected Posted: 05 Jan 2015 03:25 PM PST Last September, after years of watching, astronomers observed and recorded the largest-ever flare in X-rays from a supermassive black hole at the center of the Milky Way.

Milky Way core drives wind at 2 million miles per hour Posted: 05 Jan 2015 03:25 PM PST At a time when our earliest human ancestors had recently mastered walking upright, the heart of our Milky Way galaxy underwent a titanic eruption, driving gases and other material outward at 2 million miles per hour. Now, at least 2 million years later, astronomers are witnessing the aftermath of the explosion: billowing clouds of gas towering about 30,000 light-years above and below the plane of our galaxy.

Hubble goes high def to revisit the iconic ‘Pillars of Creation' Posted: 05 Jan 2015 03:25 PM PST In celebration of its 25th anniversary, NASA's Hubble Space Telescope has revisited the famous "Pillars of Creation" region of the Eagle Nebula (M16), providing astronomers with a sharper and wider view. As a bonus, the pillars have been photographed in near-infrared light, as well as visible light.

Electromagnetic waves linked to particle fallout in Earth's atmosphere, new study finds Posted: 05 Jan 2015 09:59 AM PST In a new study that sheds light on space weather's impact on Earth, researchers show for the first time that plasma waves buffeting the planet's radiation belts are responsible for scattering charged particles into the atmosphere.
