University College of London researchers have explained for the first time the details of how the Sun’s coronal mass ejections behave when falling back onto the star’s surface.
For the first time, astronomers have peered into the heart of an exploding star during the final minutes of its life.
NASA's Chandra X-ray Observatory has seen a fast-moving pulsar escaping from a supernova remnant while spewing out a record-breaking jet – the longest of any object in the Milky Way galaxy -- of high-energy particles.
Exploring the universe's most violent events using computer simulations is what Enrico Ramirez-Ruiz does. So in 2012, when the first detailed observations of a star being ripped apart by a black hole were reported in Nature, Ramirez-Ruiz was eager to compare the data to his simulations.
Large stars can end their lives as violently cataclysmic supernovae. Small stars, in contrast, end up as planetary nebulae—colorful, glowing clouds of dust and gas. These nebulae were once thought to be mostly spherical.
Using a novel way of combining data from the two European Space Agency (ESA) satellites Planck and Herschel, an international team of scientists has been able to locate more distant galaxy clusters than previously possible.
Two NASA spacecraft -- Hubble and Cassini -- captured 360 degree views of Saturn’s northern lights, giving a glimpse as to how the ringed planet looks when bathed in the Sun’s charged particles.
A team led by astronomers at The Australian National University has discovered the oldest known star in the Universe, which formed shortly after the Big Bang 13.7 billion years ago.
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...
