WASHINGTON, June 16, 2014 /PRNewswire-USNewswire/ -- On Thursday, June 19, NASA will host a televised update on recent progress and upcoming milestones in the agency's efforts to identify, capture and relocate an asteroid, and send astronauts to take samples of it in the 2020s. The 1-2:30 p.m. EDT event will kick off a two-day virtual workshop to highlight successes and new opportunities through NASA's Asteroid Grand Challenge, which coincides with its first anniversary....

Bullet Group
2014-06-14 03:00:23

ESA Galaxies are not as isolated as they at first glance may seem; on a cosmic scale they congregate in clumps along with dark matter and hot gas. The colorful blob in this new composite image, based on data from several telescopes including ESA's XMM-Newton, is the group of galaxies known as the Bullet Group. Its components appear to be clearly separated, with the hot gas partitioned from the rest of the mass within the group. This is the smallest object ever found to show such an effect,...

redOrbit Staff & Wire Reports - Your Universe Online If there are cracks on the ice-covered surface of Charon, an upcoming analysis of those fractures could help determine whether or not the interior of Pluto’s moon was warm enough to have been home to a subterranean ocean of liquid water. In April, research funded by the US space agency and published in the journal Icarus reported how tidally-driven fractures could have formed on the moon if its orbit was previously eccentric....

Astronomers Discover Nearly 200 Previously Unknown 'Red' Galaxies
2014-06-13 11:46:53

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online One of the greatest aspects of NASA’s astronomical research program is that the data accumulated from virtually all of the instruments – X-ray satellites, Infrared detectors, gamma-ray satellites – is available to the public. This means professional and amateur astronomers alike have the ability to make breakthrough discoveries. For instance, in 2007 Dutch school teacher Hanny van Arkel discovered a peculiar blob in an...

Asteroid 2014 HQ124
2014-06-13 11:15:52

Gerard LeBlond for redOrbit.com - Your Universe Online An asteroid, designated “2014 HQ124” at least 1,200 feet wide on its long axis, passed by Earth on June 8, 2014. It came within 776,000 miles, or approximately three times the distance to the moon. Images captured of the asteroid are some of the most detailed in NASA’s history. The asteroid was first spotted on April 23, 2014 by NASA’s NEOWISE mission. NEOWISE was adapted for capturing infrared light emitted from comets and...

Cosmic Ring
2014-06-13 05:47:06

Whitney Clavin, Jet Propulsion Laboratory The Herschel Space Observatory has uncovered a weird ring of dusty material while obtaining one of the sharpest scans to date of a huge cloud of gas and dust, called NGC 7538. The observations have revealed numerous clumps of material, a baker's dozen of which may evolve into the most powerful kinds of stars in the universe. Herschel is a European Space Agency mission with important NASA contributions. "We have looked at NGC 7538 with Herschel...

Arecibo and NASA Scientists using Earth-based radar have produced sharp views of a recently-discovered asteroid as it slid safely past our planet. Taken on June 8, 2014, the new views of asteroid 2014 HQ124 are some of the most detailed images of a near-Earth asteroid ever obtained with Arecibo Observatory and Goldstone Solar System Radar. Arecibo, Puerto Rico (PRWEB) June 12, 2014 On Sunday, June 8, 2014, asteroid 2014 HQ124 safely passed Earth a little over three times the distance from...

Gamma ray burst buried in dust
2014-06-12 04:59:01

redOrbit Staff & Wire Reports - Your Universe Online For the first time ever, scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered molecular gas in galaxies that had once been rocked by gamma ray bursts, according to new research published Wednesday in the journal Nature. The new observations reveal that the molecular gas, which serves as the fuel for the star formation process, was concentrated towards the center of the galaxies, the study...

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Dating the formation of the Earth is a difficult process, because usually geological dating methods do not work as well. Early in its existence the Earth was more fluid, with materials all mixing together in a super-heated mix. It took millions of years for differentiation and cooling to achieve the layered Earth we live on today. So traditional geological dating gives us more of a lower bound for the age of the Earth, while...

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...

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...
