redOrbit Staff & Wire Reports - Your Universe Online While experts might not know exactly how supermassive black holes grow to sizes up to a billion times that of our sun, astronomers using NASA’s Wide-field Infrared Survey Explorer (WISE) believe they have discovered the so-called cosmic seeds that will ultimately become gravity-rich regions from which light cannot escape. Black holes come in various sizes, with the smallest ones only a few times greater in mass than our sun and...

Lee Rannals for redOrbit.com - Your Universe Online Scientists have redefined the edge of the Solar System with the discovery of a new distant dwarf planet. The scientists reported in the journal Nature this week that they found 2012 VP113 sitting beyond the known edge of the Solar System. The new dwarf planet is one of thousands of distant objects believed to have formed in the inner Oort cloud. Not only does this new discovery bring into question the currently defined edge of the...

Watch The Video: Studying Other Worlds with the Help of a Starshade ] Whitney Clavin, NASA's Jet Propulsion Laboratory A spacecraft that looks like a giant sunflower might one day be used to acquire images of Earth-like rocky planets around nearby stars. The prototype deployable structure, called a starshade, is being developed by NASA's Jet Propulsion Laboratory in Pasadena, Calif. The hunt is on for planets that resemble Earth in size, composition and temperature. Rocky...

Scientists Create The First 360-Degree Virtual Map Of The Milky Way

[ Watch the Video: 360-Degree View of the Milky Way ] Lawrence LeBlond for redOrbit.com - Your Universe Online NASA’s Spitzer Space Telescope has been busy studying stars, asteroids, galaxies and other outer space objects over the past 10 years and a University of Wisconsin team of scientists has now used more than two million images produced by Spitzer to create a virtual 360-degree mosaic of our Milky Way. The team presented the new interactive map Thursday at the TEDActive 2014...

Hardy Star Survives Supernova Blast
2014-03-21 05:24:03

[ Watch the Video: What Is A Supernova? ] NASA When a massive star runs out of fuel, it collapses and explodes as a supernova. Although these explosions are extremely powerful, it is possible for a companion star to endure the blast. A team of astronomers using NASA’s Chandra X-ray Observatory and other telescopes has found evidence for one of these survivors. This hardy star is in a stellar explosion’s debris field − also called its supernova remnant − located in an HII...

Stellar Astrophysics
2014-01-12 00:00:00

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...

Planetary Astronomy

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.

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...
