Spiraling Supermassive Black Holes Do black holes glow when they collide? When merging, co-orbiting black holes are sure to emit a burst of unusual gravitational radiation , but will they emit light , well before that, if they are surrounded by gas ? To help find out, astrophysicists created a sophisticated computer simulation. The simulation and featured resulting video accurately depicts two spiraling supermassive black hole s, including the effects of Einstein's general relativity on the surrounding gas and light. The video first shows the system from the top, and later from the side where unusual gravitational lens distortions are more prominent. Numerical results indicate that gravitational and magnetic forces should energize the gas to emit high-energy light from the ultraviolet to the X-ray . The emission of such light may enable humanity to detect and study supermas...

The Fairy of Eagle Nebula The dust sculptures of the Eagle Nebula are evaporating. As powerful starlight whittles away these cool cosmic mountains , the statuesque pillars that remain might be imagined as mythical beasts . Featured here is one of several striking dust pillars of the Eagle Nebula that might be described as a gigantic alien fairy . This fairy, however, is ten light years tall and spews radiation much hotter than common fire . The greater Eagle Nebula , M16, is actually a giant evaporating shell of gas and dust inside of which is a growing cavity filled with a spectacular stellar nursery currently forming an open cluster of stars. This great pillar, which is about 7,000 light years away, will likely evaporate away in about 100,000 years. The featured image in scientifically re-assigned colors was released in 2005 as part of the fifteenth anniversary celebration ...

Mount Everest Star Trails The highest peak on planet Earth is framed in this mountain and night skyscape. On September 30, the digital stack of 240 sequential exposures made with a camera fixed to a tripod at an Everest Base Camp captured the sheer north face of the Himalayan mountain and foreground illuminated by bright moonlight. Taken over 1.5 hours, the sequence also recorded colorful star trails. Reflecting the planet's daily rotation on its axis, their motion is along gentle concentric arcs centered on the south celestial pole , a point well below the rugged horizon. The color of the trails actually indicates the temperatures of the stars. Blueish hues are from hotter stars, and yellow to reddish hues a re from stars cooler than the Sun.
