Sun's Coronal Mass Ejections Behave Like Crab Nebula's Gas Tendrils
2014-02-21 13:28:29

[ Watch the Video: Enormous Coronal Mass Ejection ] Lee Rannals for redOrbit.com - Your Universe Online Researchers from University College London have explained for the first time the details of how the Sun’s coronal mass ejections (CMEs) behave when falling back onto the star’s surface. The team has discovered that coronal mass ejections are a lot like the tendrils of gas in the Crab Nebula, which are about 6,500 light-years away from Earth and are millions of times larger....

Giant Gas Cloud Spotted By Telescope On Antarctica's Ridge A
2014-02-21 08:19:35

Deborah Smith, University of New South Wales Using a telescope installed at the driest place on earth - Ridge A in Antarctica – a UNSW-led team of researchers has identified a giant gas cloud which appears to be in an early stage of formation. Giant clouds of molecular gas – the most massive objects in our galaxy – are the birthplaces of stars. "This newly discovered gas cloud is shaped like a very long filament, about 200 light years in extent and ten light years across, with...

[ Watch the Video: Fight Between Tiny Star And Giant Asteroid ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers have found evidence that a tiny star 37,000 light-years away from Earth is being bombarded by asteroids. Scientists say PSR J0738-4042, a star located in the constellation of Puppis, has been hit with an asteroid that had a mass of about a billion tons. The team used CSIRO's Parkes Observatory telescope and another telescope in South Africa to make the...

[ Watch the Video: Sloshing Star Goes Supernova ] April Flowers for redOrbit.com - Your Universe Online For the first time, astronomers have peered into the heart of an exploding star during the final minutes of its life. This groundbreaking achievement is one of the primary goals of NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) mission, which launched in June 2012. NuSTAR is tasked to measure high energy X-ray emissions from exploding stars, also known as supernovae, and...

Exoplanet Hunter Selected By European Space Agency
2014-02-20 04:31:01

[ Watch the Video: The Newest Exoplanet Hunter - PLATO ] April Flowers for redOrbit.com - Your Universe Online One of the hottest topics in 21st century science is the exploration of planets around stars other than our own Sun. These planets are known as extrasolar planets, or "exoplanets." One of the key goals of such research is to discover and learn about the properties of Earth-like worlds in the Sun's neighborhood. The European Space Agency (ESA) is preparing a new space mission,...

Exoplanet Search Techniques Needs To Be Refined
2014-02-20 04:11:01

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online There is perhaps no field of astronomical research that more captivates our attention than the search for planets outside our solar system. In the last two decades the planet hunting community has exploded, with hundreds of new planets and planet candidates emerging each year. The holy grail, of course, would be the detection of an Earth-like world. Specifically, astronomers are looking for a planet of similar size to our...

WASHINGTON, Feb. 19, 2014 /PRNewswire-USNewswire/ -- One of the biggest mysteries in astronomy, how stars blow up in supernova explosions, finally is being unraveled with the help of NASA's Nuclear Spectroscopic Telescope Array (NuSTAR). (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The high-energy X-ray observatory has created the first map of radioactive material in a supernova remnant. The results, from a remnant named Cassiopeia A (Cas A), reveal how shock waves...

NASA Satellite Discovers Cloudy Conditions Around Black Holes

[ Watch the Video: The Cloudy Cores of Active Galaxies ] Lee Rannals for redOrbit.com - Your Universe Online An international team of astronomers used NASA’s Rossi X-ray Timing Explorer (RXTE) satellite data and found huge clouds of gas orbiting supermassive black holes. Scientists collected 16 years of data from RXTE, a decommissioned low-earth orbit satellite that was equipped with instruments that measured variations in X-ray sources. This treasure trove of data revealed a dozen...

Stellar Astrophysics

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...
