+ - The Solar oxygen crisis

Submitted by Astrophysicist
Astrophysicist (666) writes "The Astrophysical Journal publishes this week an article about the abundance of oxygen in the Sun. Oxygen (O) is the third most abundant atom in the universe, behind Hydrogen (H) and Helium (He). Most of the H and He was formed in the Big Bang, which means that O is the element most frequently produced by nuclear fusion reactions in the interior of the stars. The solar abundance of O, which is key in Astrophysics because of its use as a calibration reference for other objects, was thought to be well established since the 80s. However, recent evidence indicates that it has been overestimated by almost a factor of two. A revision of the Solar oxygen abundance would have a cascading effect on other important elements, such as Carbon, Nitrogen and Neon, whose abundance is only known relative to that of O. In addition to the impact on the chemical composition of many stars, models of solar interior may require some reworking in order to be consistent with the new data."

Black Hole Cluster Spawns Massive Cloud 74

Posted by kdawson
from the excuse-me dept.
Shifty Jim writes in with an article at space.com reporting that a cluster of galaxies harboring black holes may be the source of a massive cloud millions of light years across. Quoting: "A giant cloud of superheated gas 6 million light years wide might be formed by the collective sigh of several supermassive black holes, scientists say. The plasma cloud... might be the source of mysterious cosmic rays that permeate our universe... The plasma cloud is located about 300 million light years away near the Coma Cluster and is spread across a vast region of space thought to contain several galaxies with supermassive black holes... embedded at their centers."

+ - You don't know Jack

bumchick (201482) writes "After months (years?) of PR gaffes, here's a level-headed interview from Jack Tretton (SCEA CEO) at GamePro. Perhaps the most interesting bits is near the interview end where Jack asks GamePro:

So I guess my question back to you is this: in recent years there seems to be a closet journalist around every corner. How does that affect your ability to report to the consumer, and how does it affect the consumer's ability to sort through credible journalism and people who are mad at the world and want to knock everything? Is that a good trend for the industry?
