Kepler Space Telescope Marks Five Years in Space
2014-03-07 11:47:49

NASA's Jet Propulsion Laboratory Exactly five years ago, on March 6, 2009, NASA's Kepler Space Telescope rocketed into the night skies above Cape Canaveral Air Force Station in Florida to find planets around other stars, called exoplanets, in search of potentially habitable worlds. Since then, Kepler has unveiled a whole new side of our galaxy -- one that is teeming with planets. Because of Kepler, we now know that most stars have planets, Earth-sized planets are common, and planets...

Massive Ring Of Carbon Monoxide Discovered In Turbulent Comet Field
2014-03-07 10:10:00

[ Watch the Video: Colliding Comets Hint At Unseen Exoplanet ] Brett Smith for redOrbit.com - Your Universe Online NASA scientists have found evidence of a highly-turbulent comet field circling a star 63 light years from Earth. This cosmic shooting gallery has produced a massive ring of carbon monoxide gas and dust that also encircles the star, according to a new report published in the journal Science. According to the report authors, the comet field is probably the result of either...

MONTREAL , March 7, 2014 /PRNewswire/ -- According to the Pantheory Research Organization, a new study of type 1a supernova data has concluded, for the first time, that dark energy probably does not exist. The paper is entitled "An Alternative Universe-Scale Analytic Metrology and Related Cosmological Model." The paper was published in the February 2014 issue of the journal of Applied Physics Research, by the Canadian Center of Science and Education. This new research study...

Space Weather Shielding Provided By Plasma Plumes
2014-03-07 05:41:48

April Flowers for redOrbit.com - Your Universe Online The magnetosphere, Earth's magnetic field, stretches from the core of the planet out into space. Here, the magnetosphere meets the solar wind, a stream of charged particles emitted by the sun. The magnetosphere, for the main part, acts to shield the Earth from this high-energy solar activity. When the Earth's magnetosphere comes into contact with the sun's magnetic field in a process called "magnetic reconnection," the Earth's...

Loops of Gas and Dust Rise from Planetary Disks
2014-03-07 04:27:02

Brett Smith for redOrbit.com - Your Universe Online Almost a decade ago, scientists using NASA's Spitzer Space Telescope found that planet-forming disks around young stars are heated by starlight and glow with infrared light. However, these scientists found that additional infrared light was originating from an unknown source. Now, new models developed by NASA have revealed why these stars emit more infrared light than expected – gas and dust magnetically suspended above the disks...

WASHINGTON, March 6, 2014 /PRNewswire-USNewswire/ -- NASA's Hubble Space Telescope has recorded the never-before-seen break-up of an asteroid into as many as 10 smaller pieces. http://photos.prnewswire.com/prnvar/20081007/38461LOGO Fragile comets, comprised of ice and dust, have been seen falling apart as they near the sun, but nothing like this has ever before been observed in the asteroid belt. "This is a rock, and seeing it fall apart before our eyes is pretty amazing," said...

Hubble Space Telescope Catches Asteroid Breaking Up Due To Sunlight

[ Watch the Video: The Breakup of Asteroid P/2013 R3 ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers publishing a paper in the Astrophysical Journal Letters say they witnessed an asteroid breakup into as many as 10 smaller pieces. The team used NASA/ESA's Hubble Space Telescope to photograph the asteroid as it shredded when nearing the sun. "Seeing this rock fall apart before our eyes is pretty amazing," David Jewitt, a professor in the UCLA Department of Earth,...

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...
