Dark Matter Clues From The Center Of Our Galaxy
2014-04-03 13:57:46

A new study of gamma-ray light from the center of our galaxy makes the strongest case to date that some of this emission may arise from dark matter, an unknown substance making up most of the material universe.

While experts might not know exactly how supermassive black holes grow to sizes up to a billion times that of our sun, astronomers believe they have discovered the so-called cosmic seeds that will ultimately become gravity-rich regions from which light cannot escape.

ENERTIA® CEO Michael Sykes announces three new Extreme EX models of the Award-Winning Green kit-home series, with beefed up thermal mass for more inertia, and reflective hidden internal surfaces

Hardy Star Survives Supernova Blast

When a massive star runs out of fuel, it collapses and explodes as a supernova. Although these explosions are extremely powerful, it is possible for a companion star to endure the blast.

NASA's WISE Spacecraft Has Yet To Uncover Planet 'X' Beyond Pluto
2014-03-10 08:36:02

While NASA’s Wide-Field Infrared Survey Explorer (WISE) has uncovered thousands of new stars during its multi-year mission, it has been unable to collect any evidence supporting the supposed existence...

Astronomers Use Cluster Of Galaxies As A Giant Telescope

On a starry night, around 400 years ago, Galileo turned his primitive spyglass toward the sky. In just a few nights, he learned more about the stars than all of the scientists and philosophers before him, combined.

A Wide Range Of Masses Observed In Type Ia Supernovae
2014-03-04 13:06:14

Scientists have been confident in knowing why Type Ia supernovae are all so much alike. Most of them assumed that carbon-oxygen white dwarf stars capture additional mass by stripping it from a companion star or by merging with another white dwarf.

A giant sunspot – a magnetically strong and complex region on the sun's surface – has just appeared over the sun's horizon. This is the third trip for this region across the face of the sun, which takes approximately 27 days to make a complete rotation.

The prominent feature that allows for the existence of life on Earth is the Sun. Radiation from our closest star provides heat and energy to our planet, driving biological processes and providing the necessary conditions for liquid water to naturally exist. But our Sun is only but one star in this vast Universe. And as it turns out, most stars are quite different than the one that illuminates our day. For this reason, scientists have, for hundreds of years, attempted to study the other...

This interchange is so common that many textbooks even offer the two as having the same meaning. However, from a strictly historical perspective there are differences...

How Solar Cycles Impact Our Weather Here On Earth
2013-01-13 09:10:34

Solar cycles: what are they and why should we care about them? Solar cycles are made up of what are known as solar minimums (min) and solar maximums (max). We refer to a solar min at the time when the sun is not active with many sunspots, while a solar max is just the opposite when we see a large increase in sunspot activity. So how long do solar cycles last? Typically they run on what is known as an 11 year cycle from the max to the min and then start over again anew. As of 2012 we...

Physics
2014-01-12 00:00:00

Physics is a natural science involving the study of matter and its motion through space-time, along with related concepts such as energy and force. On a broader scale, it also involves the general analysis of nature, conducted in order to understand how the universe behaves. Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy. Physics was part of natural philosophy until the Scientific Revolution in the 16th century, when the natural...

Astronomy and Astrophysics Review
2012-04-25 09:55:47

The Astronomy and Astrophysics Review is a peer-reviewed scientific journal published quarterly by Springer Science Business Media. The editor-in-chief is Thierry Courvoisier. It was first published in April 1989. The journal covers all areas of astronomy and astrophysics, including cosmic ray physics, studies in the solar system, astrobiology, developments in laboratory or particle physics relevant to astronomy, instrumentation, computational or statistical methods with specific...
