KAT-7 Watches as Neutron Star Gobbles Up Its Companion Star and Fires the Matter Out

Astronomers Observe a Neutron Star Pulling Material from Its Companion Star

In a new study, astronomers detail their observations of a neutron star system known as Circinus X-1. Using the Karoo Array Telescope, they view the compact neutron star as it gobbles up parts of its companion star and then fires much of this matter back out again. An international team of astronomers have reported the […]

Study Reveals that the Brain Rewires Itself after Injury

Study Shows that the Brain Rewires Itself after Injury

A new study shows that parts of the prefrontal cortex take over when the hippocampus is damaged, a finding that could potentially help scientists develop new treatments for Alzheimer’s disease, stroke and other conditions involving damage to the brain. When the brain’s primary “learning center” is damaged, complex new neural circuits arise to compensate for […]

Weather on Uranus and Neptune Limited to a “Weather Layer”

Jet Streams on Uranus and Neptune Limited to a Weather Layer

In a newly published study, researchers detail the atmospheric circulation patterns of Uranus and Neptune, finding that the streams of gas observed in the atmosphere are limited to a “weather layer” of no more than about 1000 km in depth. What is the long-range weather forecast for the giant planets Uranus and Neptune? These planets […]

New Astronomical Tool Traces the Evolution of Cosmic Carbon

Scientists Investigate the Molecular Evolution of Cosmic Carbon

By using a collection of authentic PAH spectra, coupled with algorithm-driven, blind-computational analyses, astrophysicists are able to interpret previously unknown infrared emissions from polycyclic aromatic hydrocarbons (PAHs), finding that PAHs changed significantly in size, electrical charge and structure, to adjust to different environments. Scientists at NASA’s Ames Research Center, Moffett Field, California, now have the […]
