Using data from four European Space Agency satellites that fly in formation in the Earth's magnetic field, researchers have uncovered new information on how the solar wind can break through the Earth’s magnetosphere and disrupt modern life.
The sun emitted a significant solar flare, peaking at 7:42 a.m. EDT on June 10, 2014. NASA's Solar Dynamics Observatory (SDO) – which typically observes the entire sun 24 hours a day -- captured images of the flare.
A new study published in the journal Nature has found that super-powerful magnetic fields can have influence near and even counteract the forces of supermassive black holes.
The 1.6 meter telescope at Big Bear Solar Observatory (BBSO) in California has given researchers unparalleled capability for investigating phenomena such as solar flares.
Based on observations taken from the Spitzer Space Telescope, NASA scientists have uncovered evidence of a rare Type Ia supernova scenario – when a white dwarf feeds off an aging giant, to the point of explosion.
Astronomers using the NASA Fermi Gamma-ray Space Telescope to study what they thought were two different classes of black-hole-powered galaxies known as blazars now believe that they may be one and the same.
Using a laser beam 60,000 billion times more powerful than a typical laser pointer, researchers have recreated a small scale supernova and revealed that cosmic turbulence may have boosted magnetic fields to the power seen in interstellar space.
A coronal mass ejection, or CME, surged off the side of the sun on May 9, 2014, and NASA's newest solar observatory caught it in extraordinary detail.
For the first time ever, astronomers have directly confirmed that a rare and extremely massive type of star known as a Wolf-Rayet star died in a violent explosion known as a Type IIb supernova.
Many of the oldest and most massive galaxies reside together in enormous structures known as clusters, and now a team of astronomers has confirmed the existence of an unusually distant galaxy cluster.
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.

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...
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 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...
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...
