Two University of Texas at Arlington researchers want to bridge the gap between what is known about exploding stars and the remnants left behind thousands of years later. So they're trying something new - using SNSPH, a complex computer code developed at Los Alamos National Laboratory.

The sun ejects a continuous flow of electrically charged particles and magnetic fields in the form of the solar wind -- and this wind is hotter than it should be. A new study of data obtained by European Space Agency's Cluster spacecraft may help explain the mystery.

Read moreWhere do we come from? What is the universe made of? Will the universe exist only for a finite time or will it last forever? These are just some of the questions that University of California, San Diego physicists are working to answer in the high desert of northern Chile.

The findings, which demonstrate that sodium is stored in the body, have implications for blood pressure control, hypertension and salt-associated cardiovascular risk.

In 2011, a months-long blast of energy launched by an enormous black hole almost 11 billion years ago swept past Earth. Using a combination of data from NASA's Fermi Gamma-ray Space Telescope and the National Science Foundation's Very Long Baseline Array (VLBA), the world's largest radio telescope, astronomers have zeroed in on the source of this ancient outburst.

The discovery by astronomers of six likely comets around distant stars suggests that comets - dubbed "exocomets" - are just as common in other stellar systems with planets.

A new analysis of Kepler data shows that about 17 percent of stars have an Earth-sized planet in an orbit closer than Mercury. Since the Milky Way has about 100 billion stars, there are at least 17 billion Earth-sized worlds out there.

An international team of astrophysicists has shown that planetary systems with very distant binary stars are particularly susceptible to violent disruptions, more so than if they had stellar companions with tighter orbits around them.

Scientists have replaced the telescope by the microscope: Using the similarities between the structure of a crystal and the state of the cosmos in the early universe, they have explored a yet unconfirmed phenomenon, the formation of cosmic strings. These so-called "topological defects" are believed to have formed as the universe expanded shortly after the Big Bang.

Look up at the night sky and you'll see stars, sure. But you're also seeing planets - billions and billions of them. At least. That's the conclusion of a new study by astronomers at Caltech that provides yet more evidence that planetary systems are the cosmic norm.

The galaxies are orbiting on a thin, pancake-like plane at a scale 900 million times larger than our own solar system.
