Presentation on cosmic bloopers is free and open to the public WASHINGTON, Oct.
Many astronomers and astrophysicists speak of that same source of inspiration. But, while our solar system's immensity and beauty have an almost universal appeal, the astronomy and astrophysics career field has had very little representation from minority populations.
Approximately 12 million light years from Earth is a galaxy called NGC 7793, and just on the outskirts of this galaxy is a black hole, designated P13, which new research has revealed is ingesting a weight equivalent to 100 billion billion hot dogs every minute.
Extremely detailed images produced using radio telescopes spread throughout Europe and the US have allowed researchers to pinpoint the exact locations in a stellar explosion where gamma rays are emitted.
WASHINGTON, Oct. 8, 2014 /PRNewswire-USNewswire/ -- Astronomers have found a pulsating, dead star beaming with the energy of about 10 million suns.

The IAU invites all public organizations with an interest in astronomy to register on the IAU Directory for World Astronomy website for the NameExoWorlds contest, where they will in early 2015 be able to suggest names for exoplanets and their host stars.
The sun emitted a mid-level solar flare, peaking at 3:01 p.m. EDT on Oct. 2, 2014. NASA's Solar Dynamics Observatory, which watches the sun 24-hours a day, captured images of the flare.
We use our smartphones for a myriad of things, from normal phone activities to finding constellations in the night’s sky. And soon, your smartphone could be used to detect cosmic rays, much like the high-end, multimillion-dollar observatories.
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: Artistic concept of a planetary system. Credit: Wikipedia/NASA/JPL-Caltech The term Astronomy encompasses a broad range of topics, including the study of stars, galaxies, and planets. In order to focus on the different areas of study, many subfields of astronomy emerge. One such area is the study of planets known, appropriately, as Planetary Astronomy. Observational Planetary Astronomy Even within the field of Planetary Astronomy, there are several divisions to...
Image Caption: The Hubble Extreme Deep Field (XDF) was completed in September 2012 and shows the farthest galaxies ever photographed by humans. Each speck of light in the photo is an individual galaxy, some of them as old as 13.2 billion years; the observable universe is estimated to contain more than 200 billion galaxies.

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...
The Tropic of Capricorn, alternately called the Southern Tropic, is a marker of the most southerly latitude on the Earth at which the Sun can be directly overhead. This occurs at the December solstice, when the southern hemisphere is tilted towards the sun at its maximum degree. It is one of the five major circles of latitude that mark maps of the Earth. It presently lies 23 degrees 26’ 16’’ south of the Equator. Currently, the Tropic of Capricorn is drifting towards the north at...
- In Roman antiquity, the return of a person who had been banished, or taken prisoner by an enemy, to his old condition and former privileges.
- In international law, that right by virtue of which persons and things taken by an enemy in war are restored to their former status when coming again under the power of the nation to which they belonged.
