Dark energy is so difficult to understand, but this specific type of supernovae could help determine the rate at which the universe is expanding.
Astronomers have identified a previously invisible stellar cluster currently forming over 1 million new stars, according to a report in the journal Nature.
For the first time ever, NASA has managed to capture a detailed time-lapse of a "mini supernova," and they believe this catch will have a big impact on studying stellar explosions.
At the center of the image is the open star cluster NGC 6193, containing around thirty bright stars and forming the heart of the Ara OB1 association. The two brightest stars are very hot giant stars. Together, they provide the main source of illumination for the nearby emission nebula, the Rim Nebula, or NGC 6188, which is visible to the right of the cluster.
PITTSBURGH, March 10, 2015 /PRNewswire-USNewswire/ -- A newly discovered dwarf galaxy orbiting our own Milky Way has offered up a surprise -- it appears to be radiating gamma rays, according
One explosion is cool. But four? That's great. Astronomers observed a star explode as a supernova 4 different times in this effect known as the Einstein Cross.
The largest and most luminous black hole ever seen has been discovered, with a mass about 12 billion times that of the sun.
WASHINGTON, Feb. 24, 2015 /PRNewswire-USNewswire/ -- NASA has rescheduled to 3 p.m. EST Wednesday, Feb.
WASHINGTON, Feb. 23, 2015 /PRNewswire-USNewswire/ -- NASA will hold a media briefing at 1 p.m. EST Wednesday, Feb.
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...
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...
- One who brings meat to the table; hence, in some countries, the official title of the grand master or steward of the king's or a nobleman's household.
