Medium-Sized Asteroid Hit Could Unleash Ice Age

Medium-Sized Asteroid Hit Could Unleash Ice Age

Via Space.com More on the Chelyabinsk meteor. A strike by a medium-size asteroid could change Earth’s climate dramatically for a few years, making life difficult for people around the world, a new study suggests. Such an impact on land (as opposed to at sea) could cause average global temperatures to plunge to ice age levels and lead to steep drops […]

Planetary defense: NASA creates office to oversee asteroid detection

Via RT.com With heightened concern over potential ‘Armageddon’-like asteroids causing a ‘Deep Impact’ on Earth, NASA has created a new office tasked with coordinating detection of potential crashes and “planning for planetary defense.” Part of NASA’s Planetary Science Division, the Planetary Defense Coordination Office (PDCO) will supervise all NASA efforts that track near-Earth objects (NEOs), such as asteroids and comets.

Rosetta detects molecular oxygen on Comet 67P for first time

Via ABC Science: The Rosetta spacecraft has detected significant levels of molecular oxygen coming from Comet 67P/Churyumov-Gerasimenko in a discovery that has taken astronomers by surprise. The discovery, reported in the journal Nature, may provide new clues about the conditions and environment where the Earth, Sun and solar system were born 4.6 billion years ago. “This is the first comet […]

A Cataclysmic Event of a Certain Age – Evidence for a Catastrophic Episode 13,000 Years Ago

A Cataclysmic Event of a Certain Age – Evidence for a Catastrophic Episode 13,000 Years Ago

Via Phys.org July 27, 2015 At the end of the Pleistocene period,approximately 12,800 years ago—give or take a few centuries—a cosmic impact triggered an abrupt cooling episode that earth scientists refer to as the Younger Dryas. New research by UC Santa Barbara geologist James Kennett and an international group of investigators has narrowed the date to a 100-year range, sometime […]

The Sluggish Race to Guard the Earth Against Meteors – Vice.com

Via Vice.com May 22, 2015 By Rory Tolan The sky god slept like a rock. In a yawning crater cut into the side of Manhattan’s Central Park, a stone as old as the Earth had amassed a crowd. I found it in a huddle of selfie sticks, flapping brochures, and children slapping it with sweaty palms. But Tomanowos, a divine […]

Philae comet could be home to alien life, say scientists

Via The Guardian: The comet landed on by the spacecraft Philae could well be home to an abundance of alien microbial life, according to leading astronomers. Features of the comet, named 67P/Churyumov-Gerasimenko, such as its organic-rich black crust, are most likely explained by the presence of living organisms beneath an icy surface, the scientists have said. Rosetta, the European spacecraft […]
