Most Centaurs May be Comets, Finds New NASA Study

The true identity of centaurs, the small celestial bodies orbiting the sun between Jupiter and Neptune, is one of the enduring mysteries of astrophysics. Are they asteroids or comets? A new study of observations from NASA's Wide-field Infrared Survey Explorer (WISE) finds most centaurs are comets.

Electron Acceleration Found to Occur in Van Allen Radiation Belts

Two University of Iowa researchers and their colleagues have advanced scientists’ knowledge of the Earth’s Van Allen radiation belts by answering a long-standing question about the belts.

Massive Particle Accelerator Discovered in the Heart of Van Allen Radiation Belts

Using data from a NASA satellite, scientists have discovered a massive particle accelerator in the heart of one of the harshest regions of near-Earth space, a region of super-energetic, charged particles surrounding the globe and known as the Van Allen radiation belts.

Prime Near-Infrared Imaging Instrument Shipped for NASA’s James Webb Space Telescope

Lockheed Martin, under a contract from the University of Arizona, has completed assembly and testing of the Near Infrared Camera (NIRCam) and has shipped the instrument to the NASA Goddard Space Flight Center in Greenbelt, Md. NIRCam is the prime near-infrared imaging instrument for NASA’s James Webb Space Telescope (JWST).

Fermilab Plans Celebration for Safe Arrival of Circular Muon g-2 Electromagnet

For the past month, a 50-foot-wide circular electromagnet has been on a fantastic journey between two U.S. Department of Energy national labs: Brookhaven National Laboratory in New York and Fermi National Accelerator Laboratory in Illinois. On Friday, July 26, that voyage is expected to conclude. Fermilab is planning a party to celebrate the ring’s safe arrival, and everyone is invited.

New Theoretical Models May Explain Formation of the Solar System

Comets and meteorites contain clues to our solar system's earliest days. But some of the findings are puzzle pieces that don't seem to fit well together. A new set of theoretical models from Carnegie's Alan Boss shows how an outburst event in the Sun's formative years could explain some of this disparate evidence. His work could have implications for the hunt for habitable planets outside of our solar system. It is published by The Astrophysical Journal.

Large Galaxies May Keep Mass Down Through Feast and Fast Sequence

Unlike humans, galaxies don’t have an obesity problem. In fact there are far fewer galaxies at the most massive end of the galactic scale than expected and scientists have long sought to explain why. A new, UMD-led study published in the journal Nature suggests that one answer lies in a kind of feast and fast sequence through which large galaxies can keep their mass down.

New Observations May Help Solve Mystery of Missing High-Mass Galaxies

A new study published in the journal Nature shows how vigorous star formation can turn the tables on a starburst galaxy by forcing hydrogen and other gases high into the surrounding galactic halo, leaving little fuel for the next generation of stars.

Dartmouth Astrophysicists Document Immense Power of Quasar Radiation

Quasars are among the brightest, oldest, most distant, and most powerful objects in the universe. Powered by massive black holes at the center of most known galaxies, quasars can emit enormous amounts of energy, up to a thousand times the total output of the hundreds of billions of stars in our entire Milky Way.
