Chuck Bednar for redOrbit.com - Your Universe Online 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. Gamma-ray emissions were first observed by NASA’s Fermi Gamma-Ray Telescope in 2012 and are the highest-energy form of radioactive waves in the known universe. However, according to Michigan State University, how they are produced...

WASHINGTON, Oct. 8, 2014 /PRNewswire-USNewswire/ -- Astronomers have found a pulsating, dead star beaming with the energy of about 10 million suns. This is the brightest pulsar - a dense stellar remnant left over from a supernova explosion - ever recorded. The discovery was made with NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR. http://photos.prnewswire.com/prnvar/20081007/38461LOGO "You might think of this pulsar as the 'Mighty Mouse' of stellar remnants," said Fiona...

Provided by the International Astronomical Union (IAU) 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. For the first time in history the public will then be able to vote for the official name of stars and planets. The IAU Directory for World Astronomy will function as a permanent...

Karen C. Fox, NASA's Goddard Space Flight Center 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. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and...

April Flowers for redOrbit.com - Your Universe Online 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. [ Listen to the Podcast: Hunting For Cosmic Rays – With Special Guest Dr. Stephan Funk ] The app — which is only available for Android phone so far, but should be coming to other...

Steele Hill, NASA's Goddard Space Flight Center A snaking, extended filament of solar material currently lies on the front of the sun -- some 1 million miles across from end to end. Filaments are clouds of solar material suspended above the sun by powerful magnetic forces. Though notoriously unstable, filaments can last for days or even weeks. NASA's Solar Dynamics Observatory, or SDO, which watches the sun 24 hours a day, has observed this gigantic filament for several days as it...

Chuck Bednar for redOrbit.com - Your Universe Online Analysis of a massive rectangular feature buried just below the lunar surface by NASA’s Gravity Recovery and Interior Laboratory (GRAIL) spacecraft has revealed that the giant basin on the moon’s near side was likely created by ancient lava flows and not a massive asteroid collision, according to a new study. Writing in the October 1 online edition of the journal Nature, lead author Colorado School of Mines Geophysics Associate...

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...

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...

Tropic of Capricorn
2013-02-21 13:31:57

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...
