Telescope finds space blobs are pubescent galaxies
WASHINGTON (AP) — Mysterious space blobs aren’t infant galaxies as astronomers once thought. Scientists say they mostly consist of galaxies going through puberty, all hot and bothered. A new study using NASA’s Chandra X-Ray Observatory and other space and ground telescopes comes up with an explanation for these high-energy glowing blobs that have been observed for about a decade.
Astronomers looked at 29 of these gaseous blobs in one distant area of the universe, dating back to more than 11 billion years ago.
One theory was that they were young galaxies cooling off. But the new research says they are hot and chaotic with gas halos, growing supermassive black holes and about to stabilize. The blobs are the adolescent galaxies and the hydrogen gas, leftover from their creation.

If we don't change our ways soon...
A new report by the Royal Society, chaired by Nobel prize-winning biologist Sir John Sulston warns that world population must be stabilized and consumption in wealthy nations must be reduced or the entire planet is in big trouble. As the report reads: "The number of people living on the planet has never been higher, their levels of consumption are unprecedented and vast changes are taking place in the environment. We can choose to rebalance the use of resources to a more egalitarian pattern of consumption... or we can choose to do nothing and to drift into a downward spiral of economic and environmental ills leading to a more unequal and inhospitable future."This is the same warning that President Jimmy Carter gave Americans back in the 1970's - but it was ignored when Ronald Reagan came to power with a "more positive" message basically telling Americans we can do whatever we want. And then after 9/11 - Bush told us all we should go shopping and consume ever more.And now with corporations calling the shots in Washington - long-term sustainability of the planet takes a back seat to short-term profits. If we don't change our ways soon - and embrace clean, alternative energy and educate women around the plant - then we all could be headed for a rough century.-Thom(Is there any chance we will learn in time?

The modern conservative is engaged in one of man's oldest exercises in moral philosophy; that is, the search for a superior moral justification for selfishness.
