A close series of consecutive exposures are combined in this intriguing

Our Sun is not a giant blueberry.

Data from a British high-seas scientific expedition in the 1870s have provided further confirmation of human-produced global warming over the past century.

Beautiful barred spiral

What on Earth is that?

This image shows a cutting-edge solar-electric propulsion thruster in development at NASA's Jet Propulsion Laboratory, Pasadena, Calif., that uses xenon ions for propulsion. An earlier version of this solar-electric propulsion engine has been flying on NASA's Dawn mission to the asteroid belt. This engine is being considered as part of the Asteroid Initiative, a proposal to robotically capture a small near-Earth asteroid and redirect it safely to a stable orbit in the Earth-moon system where astronauts can visit and explore it. This image was taken through a porthole in a vacuum chamber at JPL where the ion engine is being tested. Image credit: NASA/JPL-Caltech

The following is a statement from NASA's associate administrator for space technology, Michael Gazarik, about his meetings this week in Europe to discuss potential cooperation on development of space technologies that will enable NASA's future missions. These include the asteroid initiative announced in the president's fiscal year 2014 budget proposal.

Supercomputers have helped reveal that galaxies bulk up in mass by feeding off cosmic swirly straws of gas.

NASA Administrator Charles Bolden met with members of the asteroid initiative team at NASA's Jet Propulsion Laboratory, Pasadena, Calif., today.

NASA's Summer of Innovation project is accepting proposals through Monday, June 10, from organizations that want to offer students science, technology, engineering and mathematics (STEM) educational experiences this summer.

The Ring Nebula's distinctive shape makes it a popular illustration for astronomy books. But new observations by NASA's Hubble Space Telescope of the glowing gas shroud around an old, dying, sun-like star reveal a new twist.

Astronauts aboard the International Space Station (ISS) photographed this striking view of Pavlof Volcano on May 18, 2013. The oblique perspective from the ISS reveals the three dimensional structure of the ash plume, which is often obscured by the top-down view of most remote sensing satellites. Situated in the Aleutian Arc about 625 miles (1,000 kilometers) southwest of Anchorage, Pavlof began erupting on May 13, 2013. The volcano jetted lava into the air and spewed an ash cloud 20,000 feet (6,000 meters) high. When photograph ISS036-E-2105 (top) was taken, the space station was about 475 miles south-southeast of the volcano (49.1° North latitude, 157.4° West longitude). The volcanic plume extended southeastward over the North Pacific Ocean. Image Credit: NASA

NASA's instruments for the next in a series of missions to chart sea level and improve weather, climate and ocean forecasts have shipped overseas for spacecraft integration.

A massive and rare merging of two galaxies has been spotted in images taken by the Herschel space observatory, a European Space Agency mission with important NASA participation.

Two new models with implications for NASA's Cassini mission suggest the onset of spring in Titan's northern hemisphere could bring waves and hurricanes.
