Combined observations from three spacecraft show that Jupiter's brightest auroral features recorded to date are powered by both the volcanic moon Io and interaction with the solar wind.
On Aug. 27, 2016, the Juno spacecraft made its first close pass around our solar system's largest planet, Jupiter, obtaining insights into its atmosphere and interior that challenge previous assumptions.
A team of astronomers including Carnegie's Eduardo Bañados and led by Roberto Decarli of the Max Planck Institute for Astronomy has discovered a new kind of galaxy which, although extremely old -- formed less than a billion years after the Big Bang -- creates stars more than a hundred times faster than our own Milky Way.
Online volunteers have helped astronomers at The Australian National University find a star that exploded 970 million years ago, predating the dinosaurs' time on Earth.
Storms associated with the advancing monsoon in the Northern Indian Ocean's Bay of Bengal were analyzed by NASA with the GPM or Global Precipitation Measurement mission core satellite.
When astronomers took a new look at a famous galaxy with the upgraded Very Large Array, they were surprised by the appearance of a new, bright object that had not appeared in previous images.
CERN research results deliver no evidence for the existence of solar axions.
Plasma propulsion concepts are gridded-ion thrusters that accelerate and emit more positively charged particles than negatively charged ones. To enable the spacecraft to remain charge-neutral, a 'neutralizer' injects electrons to exactly balance the positive ion charge in the exhaust beam, but this neutralizer requires additional power from the spacecraft. Researchers are investigating how the radio-frequency self-bias effect can be used to remove the neutralizer altogether. They report their work in this week's Physics of Plasmas.
Some NASA missions fundamentally change the world of science or help win Nobel prizes, but only one saves thousands of lives worldwide every year.
In the icy bodies around our solar system, radiation emitted from rocky cores could break up water molecules and support hydrogen-eating microbes. To address this cosmic possibility, a University of Texas at San Antonio (UTSA) and Southwest Research Institute (SwRI) team modeled a natural water-cracking process called radiolysis. They then applied the model to several worlds with known or suspected interior oceans, including Saturn's moon Enceladus, Jupiter's moon Europa, Pluto and its moon Charon, as well as the dwarf planet Ceres.
