Chandra And XMM-Newton Show Direct Measurement Of Distant Black Hole's Spin
2014-03-06 08:15:43

[ Watch the Video: Measuring a Distant Black Hole's Spin ] NASA Astronomers have used NASA's Chandra X-ray Observatory and the European Space Agency's (ESA's) XMM-Newton to show a supermassive black hole six billion light years from Earth is spinning extremely rapidly. This first direct measurement of the spin of such a distant black hole is an important advance for understanding how black holes grow over time. Black holes are defined by just two simple characteristics: mass and...

redOrbit Staff & Wire Reports - Your Universe Online A team of researchers from the University of Arizona’s Department of Astronomy have managed to use an Earth-based telescope to capture images of a world outside of our solar system, according to research scheduled to be published in an upcoming edition of The Astrophysical Journal. The telescope used essentially the same type of imaging sensor found in a standard digital camera instead of an infrared detector, and while the...

Shadows Of Petra Awaken Its Astronomical Orientation
2014-03-05 13:20:32

SINC During the winter solstice, the sun is filtered into the Monastery at Petra, Jordan, illuminating the podium of a deity. Just at this moment, the silhouette of the mountain opposite draws the head of a lion, a sacred animal. These are examples from a study where researchers from Instituto de Astrofisica de Canarias and CSIC (Spain) showed how celestial events influenced the orientation of the great constructions of the Nabataeans. The movement of the Sun in the skies of Petra...

[ Watch The Video: MUSE Views the Unusual Galaxy NGC 4650A ] ESO A new innovative instrument called MUSE (Multi Unit Spectroscopic Explorer) has been successfully installed on ESO’s Very Large Telescope (VLT) at the Paranal Observatory in northern Chile. MUSE has observed distant galaxies, bright stars and other test targets during the first period of very successful observations. Following testing and preliminary acceptance in Europe in September 2013, MUSE was shipped to...

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online The holy grail of planetary astronomy is the search for a potentially habitable planet, or even better, one that is shown to already contain life. There are various parameters that are needed in order to ascertain the habitability of worlds, such as whether liquid water can be sustained on its surface. Recent studies, however, have found that identifying some of these characteristics is rather difficult, and we may in fact...

Large Asteroid Set To Pass Between Earth And Moon
2014-03-04 14:50:08

Lee Rannals for redOrbit.com - Your Universe Online An asteroid with a diameter about the size of an 80-story building is sweeping by Earth and the moon on Wednesday. Asteroid 2014 CU13 was first discovered on February 11th by Mt. Lemmon Survey. Since then, the asteroid has been viewed over 230 times, but there still remains a lack of information in trying to pinpoint the space rock’s exact orbit. Slooh will be attempting to offer up a webcast of the asteroid as it makes its...

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...
