mars and the sun
2014-09-24 07:50:31

Looking across the Mars landscape presents a bleak image: a barren, dry rocky view as far as the eye can see. But scientists think the vista might once have been quite different. It may have teemed with water and even been hospitable to microbial life. What changed?

The Difference Between Flares And CMEs
2014-09-23 03:49:47

There are many kinds of eruptions on the sun. Solar flares and coronal mass ejections both involve gigantic explosions of energy, but are otherwise quite different.

gravitational waves

As one team of experts has published a study claiming to have discovered hints of gravitational waves in stars, another has released a new galactic dust map that casts doubts on previous research claiming to have detected such waves earlier this year.

NASA Releases Interface Region Imaging Spectrograph Footage Of X-class Flare
2014-09-18 03:30:06

On Sept. 10, 2014, NASA's newest solar observatory, the Interface Region Imaging Spectrograph, or IRIS, mission joined other telescopes to witness an X-class flare – an example of one of the strongest solar flares -- on the sun.

supermassive black hole
2014-09-18 04:40:12

Astronomers have discovered a supermassive black hole in the ultracompact dwarf galaxy M60-UCD1, making it the smallest galaxy ever found to host one of these enormous light-sucking objects.

Type Ia supernova
2014-09-14 04:24:52

Less than two months after it first began repeatedly scanning the sky, the ESA’s Gaia space observatory has discovered its first supernova – a powerful stellar explosion that had occurred in a distant galaxy located some 500 million light-years from Earth.

The annual award recognizes leaders in disruptive technologies; winners will be announced in October. Kirkland, Washington (PRWEB) September 12, 2014

supernova puzzle 1
2014-09-11 03:00:38

A team led by Gastón Folatelli at the Kavli IPMU, the University of Tokyo, has found evidence of a hot binary companion star to a yellow supergiant star, which had become a bright supernova.

quasar
2014-09-11 03:30:44

New work from Carnegie’s Hubble Fellow Yue Shen and Luis Ho of the Kavli Institute for Astronomy and Astrophysics (KIAA) at Peking University solves a quasar mystery that astronomers have been puzzling over for 20 years.

Stellar Astrophysics

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...

Image Caption: NGC 4414, a typical spiral galaxy in the constellation Coma Berenices, is about 56,000 light-years in diameter and approximately 60 million light-years distant. Credit: NASA/ESA/Wikipedia What is Astrophysics? For much of the modern age the term Astrophysics has been used synonymously with Astronomy. 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...
