Stephen Hawking: "Why Isn't the Milky Way Crawling With Mechanical or Biological Life?" (A New Year's Weekend Classic)

Hawking asks. "I discount suggestions that UFO's contain beings from outer space. I think any visits by aliens, would be much more obvious, and probably also, much more unpleasant. " Hawking continues: "What is the explanation of why we have not been visited? One possibility is that the argument, about the appearance of life on Earth, is wrong. We are used to thinking of intelligent life, as an inevitable consequence of evolution, Hawking emphasized, but it is more likely that evolution is a random process, with intelligence as only one of a large number of possible outcomes. Intelligence, Hawking believes contrary to our human-centric existece, may not have any long-term survival value. Evol_massive5.swf (application/x-shockwave-flash Object)

Scientists Now Know: We're From Sagittarius Dwarf Galaxy!

Summary & comments by Dan Eden for Viewzone Imagine the shock of growing up in a loving family with people you call "Mum" and "Dad" and then, suddenly, learning that you are actually adopted! This same sense of shock came as scientists announced that the Sun, the Moon, our planet and its siblings, were not born into the familiar band of stars known as the Milky Way galaxy, but we actually belong to a strange formation with the unfamiliar name of the Sagittarius Dwarf galaxy!

How can this be? Using volumes of data from the Two-Micron All Sky Survey (2MASS), a major project to survey the sky in infrared light led by the University of Massachusetts, the astronomers are answering questions that have baffled scientists for decades and proving that our own Milky Way is consuming one of its neighbors in a dramatic display of ongoing galactic cannibalism. A new infra red digital survey of the entire sky was made in 2003. Not any more. Viewzone || Comments?

The Top 5 Astronomical Events to Witness Before You Die

In ancient times, however, human civilizations based their entire calendar, and thus their way of life, upon what they saw in the cosmos. While humanity’s interest in astronomy has diminished over the centuries, the sky remains nonetheless spectacular. Few people have the time to go stargazing every night, but here are 5 celestial events so awe-inspiring, everyone must see them in their lifetime. 5. Perseid Meteor Shower Next Occurrence: August 9-14, 2011 Every August, the night sky lights up with a dazzling display known as the Perseid meteor shower. 4. Next Occurrence: June 15, 2011 in Africa Ever get bored with the predictably drab hue of the moon? 3. Occurrence: Year round More commonly known as the Northern Lights, Aurora is a fantastic light display that occurs at extreme Northern or Southern latitudes. 2. 1.

Radiation No Concern for Space Crops?

Now researchers have discovered that oil-rich flax plants grown in the highly radioactive soil can apparently adapt and thrive with few problems. The first generation survived with changes in barely 5 percent of the plant proteins, and researchers have also collected results from a second generation of flax grown in a radioactive plot of land near Chernobyl. But a mystery remains as to how the flax – a source of plant fiber and dietary oil – has adapted biochemically to the highly radioactive environment.

The Brain—Information about the Brain

—René Descartes, 17th-century philosopher Few of us question the crucial importance of the brain. It is vital to our existence. Our brains enable us to think, as René Descartes so skillfully pointed out nearly 400 years ago.
