Martian Meteorites Offer Evidence Of Early Atmosphere On Red Planet
2014-04-17 06:47:34

Lawrence LeBlond for redOrbit.com - Your Universe Online Martian meteorites that fell to Earth are revealing secrets of an early atmosphere on Mars that is hidden in the chemical signatures of each ancient rock. Geologists, who collected and studied 40 of these otherworldly rocks, have found an important key to how the atmospheres of Mars and Earth diverged very early in the evolution of the Solar System. The results of this study, published in the journal Nature, will help guide...

Gum 41: A Study In Scarlet
2014-04-16 10:21:53

ESO [ Watch The Video: Zooming In On The Star Formation Region Gum 41 ] This area of the southern sky, in the constellation of Centaurus (The Centaur), is home to many bright nebulae, each associated with hot newborn stars that formed out of the clouds of hydrogen gas. The intense radiation from the stellar newborns excites the remaining hydrogen around them, making the gas glow in the distinctive shade of red typical of star-forming regions. Another famous example of this phenomenon...

Tilted orbits

redOrbit Staff & Wire Reports - Your Universe Online While experts have long believed that life could not exist on planets with a fluctuating tilt in their orbits, new research appearing in the April issue of the journal Astrobiology suggests that such obliquity variations could actually increase the planetary habitability in those worlds. According to Weber State University physics professor John Armstrong, University of Washington astronomer Rory Barnes and their colleagues, these...

Saturn's Hexagon: An amazing Phenomenon
2014-04-15 10:10:02

Universidad del País Vasco Researchers of the University of the Basque Country reveal some of the secrets of Saturn's mysterious hexagonal wave, including its rotation period, which could be that of the planet itself In 1980 and 1981 NASA's Voyager 1 and 2 space probes passed for the first time over the planet Saturn, located 1,500 million km from the Sun. Among their numerous discoveries they observed a strange, hexagon-shaped structure in the planet's uppermost clouds surrounding its...

Cassini Eyes Possible New Moon Forming In Saturn's Orbit
2014-04-15 08:45:46

Brett Smith for redOrbit.com - Your Universe Online Newly released images from NASA’s Cassini probe have revealed the “birthing” of a tiny moon in orbit around Saturn. The images, taken exactly one year ago on Tuesday, showed evidence of the formation of a tiny icy moon, named “Peggy” – according to a new report on the find in the journal Icarus. The study authors said the discovery could provide information about the formation of Saturn’s other moons as well as the...

Supercomputer Simulations Shed Light On How Black Holes Swallow Stars
2014-04-14 13:51:10

Brett Smith for redOrbit.com - Your Universe Online When a star orbits too close to a galaxy’s central supermassive black hole, it gets torn apart and sucked in by gravitational forces – a phenomenon known as an a tidal disruption. In a new study, researchers from Georgia Institute of Technology and the Max Planck Institute in Germany have used computational and theoretical models to describe the dynamics of these cosmic events that cause massive flares of light and energy....

NASA Invites You To Join In The Cassini Name Game
2014-04-14 11:59:56

NASA As NASA's Cassini mission approaches its 10th anniversary at Saturn, its team members back here on Earth are already looking ahead to an upcoming phase. Starting in late 2016, the Cassini spacecraft will repeatedly climb high above Saturn's north pole, flying just outside its narrow F ring. Cassini will probe the water-rich plume of the active geysers on the planet's intriguing moon Enceladus, and then will hop the rings and dive between the planet and innermost ring 22 times....

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...

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...
