New Image Shows Galactic Serial Killer
2014-04-02 13:48:59

[ Watch The Video: Panning Across The Galaxies NGC 1316 And 1317 ] ESO This new image from the MPG/ESO 2.2-meter telescope at ESO’s La Silla Observatory in Chile shows two contrasting galaxies: NGC 1316, and its smaller neighbor NGC 1317. These two are quite close to each other in space, but they have very different histories. The small spiral NGC 1317 has led an uneventful life, but NGC 1316 has engulfed several other galaxies in its violent history and shows the battle scars....

Lunar Eclipse Tetrad Expected To Begin In April
2014-04-14 11:07:26

Brett Smith for redOrbit.com - Your Universe Online Skywatchers across North America will want to mark their calendars for April 15 – the next lunar eclipse. Expected to be visible across the entire United States, weather permitting, the upcoming eclipse is the first of four total eclipses expected to occur over the next year-and-a-half at two-month intervals – a phenomenon known as a tetrad. There are three types of lunar eclipses: penumbral, partial and total. A penumbral...

Astronomers Given A Better Ruler In The Search For Extrasolar Planets
2014-03-31 08:04:47

NIST Researchers at the National Institute of Standards and Technology (NIST) have rejuvenated a technique for finding planets near distant stars. New measurements of light from special lamps could help astronomers find planets hidden in data from more than a decade's worth of extrasolar planet searches, as well as improve telescopes' current capabilities. Finding extrasolar planets is tricky. Seen through a telescope, planets in the "habitable zone"—a region close to a star, where...

University of Cambridge Video of magnetic field lines 'slipping reconnection' bring scientists a step closer to predicting when and where large flares will occur Scientists have for the first time witnessed the mechanism behind explosive energy releases in the Sun's atmosphere, confirming new theories about how solar flares are created. New footage put together by an international team led by University of Cambridge researchers shows how entangled magnetic field lines looping from...

Don’t Forget F-type Stars In The Search For Life
2014-03-27 13:19:34

University of Texas at Arlington Scientists searching for habitable planets beyond Earth shouldn’t overlook F-type stars in favor of their more abundant, smaller and cooler cousins, according to new research from University of Texas at Arlington physicists. Stars fall into seven lettered categories according to their surface temperature, but they also differ in other factors such as mass, luminosity and abundance in the universe. Scientists looking for habitable planets typically...

When all 64 MeerKAT antennas are operational, the instrument radio telescope will be sensitive enough to pick up a cell phone signal from Saturn. NEWTON, N.C., March 27, 2014 /PRNewswire/ -- General Dynamics SATCOM Technologies and Stratosat Datacom (Pty) Ltd., a South African company, have completed the installation of the first of 64 MeerKAT radio telescope antennas that will form the MeerKAT telescope array. The array is located in South Africa's Karoo region and will be a technologically...

Lick's Automated Planet Finder Has Found Two New Planetary Systems
2014-03-27 12:31:13

By Tim Stephens, UC Santa Cruz In its first months of operation, the APF has found two new planetary systems, giving astronomers a taste of planetary riches to come Lick Observatory's newest telescope, the Automated Planet Finder (APF), has been operating robotically night after night on Mt. Hamilton since January, searching nearby stars for Earth-sized planets. Every night the fully autonomous system checks the weather, decides which stars to observe, and moves the telescope from star...

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...
