New images from Rosetta show that an 800-mile-long cloud of dust, known as a coma, has sprouted from the core of the comet 67P/Churyumov-Gerasimenko. Rosetta's captured this coma in a series of photos taken between March 27 and May 4.

The video — a supercomputer simulation created by researchers at NASA's Goddard Space Flight Center — chronicles the growth of a spiral galaxy, beginning with its birth shortly after the Big Bang that created the universe 13.8 billion years ago.

Known as Cepheid variables, the stars have positions and young ages that indicate a warp to the galaxy's arm. This was previously suggested by observations of dust but had not been shown by the presence of stars.

A single "runaway" star in a distant star cluster could explain how a massive supernova avoided collapsing into a black hole, leaving behind a remnant object instead.

Discovery of runaway companion star points to a mass-exchange during a supernova explosion; weird conditions that lead to the weird, violent object called a magnetar. -- Full Story: http://goo.gl/Xn8xIt

Spacesuits are vital for astronauts. They protect space travelers during launch and landing, and allow trips outside for spacewalks to make repairs or upgrades. See photos of how spacesuits have evolved during the first decades of human spaceflight.

Visualized through supercomputers, the violent dance of intergalactic gas, stars, dust and dark matter forms a large spiral galaxy like our own Milky Way. A few smaller galaxies are ‘eaten’ along the way.

There are many mysteries about the enigmatic ringed gas giant, but the curious mechanism behind Saturn’s ‘spokes’ is one of the more intriguing puzzles.

In this simulation, 2 neutron stars weigh in at 1.4 and 1.7 solar masses and are separated by only 11 miles. Intense tidal forces pull the stars apart as they spiral towards each other and the black hole is formed amidst the chaos.

Using satellite data, researchers located "grounding lines" (points underneath glaciers where melting begins) and determined these lines were retreating further away from the sea each year. The West Antarctic glaciers are seeing the highest melt rate

A newly christened telescope imager built to snap photos of alien planets around distant stars is the most sensitive camera of its kind, according to preliminary test. The Gemini Planet Imager (GPI), installed on the Gemini South telescope in Chile, is de

The star is streaking through space at 1.4 million mph relative to our solar system, about three times faster than a typical star. It lies 42,400 light-years from Earth and is cruising toward the halo of dark matter that surrounds the galaxy.

Bone loss is a serious issue that has plagued astronauts since the dawn of the Space age. In the microgravity environment bones are remodeled with a decrease in mineral density.

After 40 years of observation, NASA and University of California researchers agree that melting of the West Antarctic Glacier has passed the point of no return. It contains enough ice to raise sea levels ~4 feet, but could take centuries to melt.
