Somewhere between 7 and 8 a.m. on June 30th, 1908, a massive explosion occurred near the Tunguska River in what is now Krasnoyarsk Krai of Russia. Numerous theories have emerged throughout the last century attempting to describe what it was that caused this mysterious explosion, dubbed the Tunguska Event.
Eyewitnesses described a diffuse bright ball
two or three times larger than the sun but not as bright; the trail was a
"fiery-white band."

It’s happening again, scientists watch a Sci-Fi movie and then a few years later, they’ve figure out a way to recreate the outlandish ideas in real life. Who ever said Hollywood was good for nothing. Well, a lot of people actually, but they were wrong!
Remember how the fictional billionaire John Hammond resurrected the extinct dinosaurs in Steven Spielberg's Jurassic Park? Now real paleontologists are piecing together the complete genomes of long-dead species such as the woolly mammoth and the Neanderthals in an effort to bring them back to life.

We posted yesterday about NASA's Dawn mission, which will launch from Cape Canaveral July 7th, on a mission to study the "dwarf planets" Ceres and Vesta in the Asteroid Belt between Jupiter and Saturn.
Asteroids are believed to be the building blocks of planets - primordial relics left over from the formation of the Solar System 4.6 billion years ago.
We thought it would be a perfect follow up to examine what the scientific world thinks would happen to the human species and life on Earth in general if an asteroid the size of the one that created the famous K/T Event of 65 million years ago at the end of the Mesozoic Era that resulted in the extinction of the dinosaurs impacted our planet.

Leonard Nimoy takes us on a fascinating robotic space probe to the very beginnings of our Solar System in this brilliantly animated 13-minute glimpse of NASA's Dawn mission scheduled to launch in July 7th. The movie features a look into the planning, instrumentation and technological challenges of this one-of-a kind mission into the heart of the doughnut-shaped asteroid belt between and Jupiter.
“I think of Dawn as two journeys,” says UCLA's Christopher Russell, who proposed the mission to NASA. (Russell, UCLA professor of geophysics and space physics, has spent 15 years working on NASA’s Dawn mission). “One is a journey into space. This is analogous to what ancient explorers did, who knew there was unexplored territory and wanted to discover what was there. We’re going to explore a region for the first time to find out what the conditions are today.

That was a question posed by VoIP pioneer Jeff Pulver recently. Where else? On Twitter. To his question, prominent blogger and highly regarded VC Fred Wilson answered, "it's an asynchronous and public form of chat." It is that - but it is much, much more.
Some of the most prominent names in technology (the two above, included) are regular Tweeters. Hugh MacLeod is, now, another. When Hugh posted the above cartoon in April, even he had no idea that it would soon apply to him. And in a post he blogged last week, he states:
