Chuck Bednar for redOrbit.com - Your Universe Online Astrophysicists and computational astronomers from the University of California, Santa Cruz have discovered why sibling stars look alike – those formed from a single cloud share the same chemical fingerprint due to early, fast and turbulent mixing of gas in the giant molecular clouds where star formation occurs. Stars are made primarily of hydrogen and helium, but they also contain trace amounts of elements such as carbon, oxygen...

Two Sources Of Helium Produced By Ancient Yellowstone Activity

[ Watch the Video: Yellowstone Releasing Ancient Helium ] Lawrence LeBlond for redOrbit.com - Your Universe Online As one might expect, Yellowstone National Park’s hot springs, geysers and other hydrothermal vents release gases stored deep below the Earth, including carbon dioxide and methane. Another gas has also been discovered to be squeaking out of Yellowstone’s vents, and while it is a common gas released from volcanic rocks, in this region, most of it comes from a much...

Earthen Crust Oxygen Got Its Start During Creation Of Solar System

April Flowers for redOrbit.com - Your Universe Online A long standing mystery in the formation of the Solar System has been solved by cosmochemists from the University of California, San Diego (UCSD). In the oldest, most pristine rocks, oxygen, the most abundant element in the Earth's crust, follows a strange, anomalous pattern that must result from a different chemical process than the well-understood reactions that form minerals containing oxygen on Earth. "Whatever the source of...

Cooking Up Our Solar System, What's The Recipe?
2013-02-21 05:05:42

April Flowers for redOrbit.com - Your Universe Online A research team from the University of California, San Diego is hoping to learn how our solar system evolved by studying the origins of different isotope ratios among the elements that make up today´s smorgasbord of planets, moons, comets, asteroids, and interplanetary ice and dust. The scientists are led by Mark Thiemens, Dean of the Division of Physical Sciences, who has worked on this problem for over three decades. Most...

Neil deGrasse Tyson, author and host of the NOVA series, "Origins, Fourteen Billion Years of Cosmic Evolution", gives a galvanizing tour of the cosmos revealing what the universe has been up to while turning part of itself into us. Astrobiology Magazine -- "On this single planet called Earth, there co-exist (among countless other life forms), algae, beetles, sponges, jellyfish, snakes, condors, and giant sequoias. Imagine these seven living organisms lined up next to each other in one-place....
