Observations from Fermi's Large Area Telescope (magenta line) show that gamma rays from LMC P3 rise and fall over the course of 10.3 days. The companion is thought to be a neutron star. Illustrations across the top show how...
The SwRI-developed Alice ultraviolet spectrograph, shown here during final integration, collected more than 70,000 spectra during a 2-year mission orbiting comet 67P/Churyumov-Gerasimenko. The instrument performed flawlessly during the ESA/NASA Rosetta mission, which ends Sept. 30, 2016.Credit: Image Courtesy of...

Astronomers have found distinct spiral arms in the disk of gas and dust surrounding...
Processes in Mars' surface material can explain why particular xenon (Xe) and krypton (Kr) isotopes are more abundant in the Martian atmosphere than expected, as measured by NASA's Curiosity rover. Cosmic rays striking barium (Ba) or bromine (Br) atoms...
This artist's impression shows the molecules found in a hot molecular core in the Large Magellanic Cloud using ALMA. This core is the first such object to be found outside the Milky Way, and it has significantly different chemical...

This image of galaxy cluster Abell 2744, also called Pandora's Cluster, was taken by the Spitzer Space Telescope. The gravity of this galaxy cluster is strong enough that it acts as a lens to magnify images of more...

The solar system is a dusty environment, with trillions of cosmic dust particles left behind by comets and asteroids that orbit the sun. All this dust forms a relatively dense cloud through which Earth travels, sweeping up the interplanetary...

Researcher Don Hood from LSU and colleagues at collaborating universities studied an unusual region on Mars — an area with...
This composite image shows suspected plumes of water vapor erupting at the 7 o'clock position off the limb of Jupiter's moon Europa. The plumes, photographed by NASA's Hubble's Space Telescope Imaging Spectrograph, were seen in silhouette as the moon...
