asteroid impact
2014-04-10 08:39:56

Brett Smith for redOrbit.com - Your Universe Online Earth was irrevocably changed when the dinosaurs were wiped out about 65 million years ago by a massive asteroid, but a much bigger asteroid that struck the Earth nearly 3.3 billion years ago is thought to have shaped parts of Africa. Now, a new study published in the journal Geochemistry, Geophysics, Geosystems has outlined the details surrounding that massive impact, such as the creation of a crater about 300 miles across and...

The unfolding story of two NYC men — Cooper Boone and Mark Veeder — and their quest to have children via surrogacy at New England Fertility. New York City, NY (PRWEB) April 09, 2014 New Yorkers Cooper Boone and Mark Veeder met on the footsteps of a beautiful old farmhouse in 2001 and have been inseparable ever since. They’ve had adventures, challenges, losses, and wins — a charmed life some would say. Yet through it all, the dream of one day having a family remained. That was all...

Celestial Diamond Ring Created By Chance Meeting
2014-04-09 11:35:16

[ Watch The Video: Zooming In On The Planetary Nebula Abell 33 ] ESO Astronomers using ESO’s Very Large Telescope in Chile have captured this eye-catching image of planetary nebula PN A66 33 — usually known as Abell 33. Created when an aging star blew off its outer layers, this beautiful blue bubble is, by chance, aligned with a foreground star, and bears an uncanny resemblance to a diamond engagement ring. This cosmic gem is unusually symmetric, appearing to be almost circular...

[ Watch the Video: A Lunar Eclipse And The LRO ] Brett Smith for redOrbit.com - Your Universe Online Sky-watchers in North America are in for a treat as they will be able to see the entire upcoming lunar eclipse on April 15 from start to finish. While the eclipse is something to look forward to for late-night amateur astronomers, the upcoming celestial event will be a bit of a complication for NASA scientists in charge of the Lunar Reconnaissance Orbiter (LRO), which is currently...

Scientists Make The Most Precise Measurment Of Early Universe Yet
2014-04-08 07:50:37

Lawrence LeBlond for redOrbit.com - Your Universe Online Two recent studies of the early Universe using the Baryon Oscillation Spectroscopic Survey (BOSS), a component of the third Sloan Digital Sky Survey (SDSS-III), have made the most accurate measurement of the rate of expansion in the early Universe to date. BOSS has pioneered the use of quasars to map density variations in intergalactic gas at high redshifts to trace the structure of the young Universe. BOSS helps scientists chart...

simulation of the gas cloud G2's encounter with the supermassive black hole Sgr A*
2014-04-06 06:02:32

Megan Fellman, Northwestern University Gas cloud’s fate could reveal information on growth of supermassive black holes Right now a doomed gas cloud is edging ever closer to the supermassive black hole at the center of our Milky Way galaxy. These black holes feed on gas and dust all the time, but astronomers rarely get to see mealtime in action. Northwestern University’s Daryl Haggard has been closely watching the little cloud, called G2, and the black hole, called Sgr A*, as part...

Monster Of A Galaxy Cluster - El Gordo Lives Up To Its Nickname
2014-04-04 07:03:29

April Flowers for redOrbit.com - Your Universe Online | Source Material Provided by NASA El Gordo is Spanish for "the fat one," and the nickname of the largest galaxy known galaxy cluster in the distant universe, ACT-CLJ0102-4915. A new study from NASA's Hubble Space Telescope reveals that the galaxy cluster, which is 9.7 billion light-years from Earth, definitely lives up to its nickname. According to a NASA report, a team of astronomers measured how much the cluster's gravity warps...

Small Asteroid Regolith Formed By Thermal Fatigue
2014-04-04 06:21:44

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Small asteroids contain a layer of loose, unconsolidated rock and dust known as a regolith composed of centimeter-sized fragments and smaller particles. New research from researchers at the Observatoire de la Côte d'Azur, Hopkins Extreme Materials Institute at Johns Hopkins University, Institut Supérieur de l'Aéronautique et de l'Espace and Southwest Research Institute (SwRI), have now determined that this layer is formed by...

Ocean Inside Enceladus
2014-04-04 04:46:48

redOrbit Staff & Wire Reports - Your Universe Online The Cassini spacecraft and Deep Space Network have discovered evidence of a large underground ocean of liquid water on one of Saturn’s moons, suggesting that the satellite could be home to extraterrestrial microbes, according to research appearing in Friday’s edition of the journal Science. Marc Kaufman of National Geographic reports the ocean is located between the rocky core and a layer of thick ice on Enceladus , one of...

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...
