Dark energy alternatives to Einstein are running out of room

Research by University of Arizona astronomy professor Rodger Thompson finds that a popular alternative to Albert Einstein's theory for the acceleration of the expansion of the universe does not fit newly obtained data on a fundamental constant, the proton to electron mass ratio.

Next-generation adaptive optics brings remarkable details to light in stellar nursery

A new image released today reveals how Gemini Observatory's most advanced adaptive optics (AO) system will help astronomers study the universe with an unprecedented level of clarity and detail by removing distortions due to the Earth's atmosphere. The photo, featuring an area on the outskirts of the famous Orion Nebula, illustrates the instrument's significant advancements over previous-generation AO systems.

Researchers try new approach for simulating supernovas

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.

Cluster mission indicates turbulent eddies may warm the solar wind

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.

New telescopes to give researchers glimpse of the beginning of time

Where 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.

Simulated Mars mission reveals body's sodium rhythms

Researchers report that - in contrast to the prevailing dogma - sodium levels fluctuate rhythmically with 7-day and monthly cycles. The findings, which demonstrate that sodium is stored in the body, have implications for blood pressure control, hypertension and salt-associated cardiovascular risk.

Galaxy's gamma-ray flares erupted far from its black hole

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.

At least one in six stars has an Earth-sized planet

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.
