New Earth-Orbiting Microwave Gun is Making Killer Maps of Wind Dynamics

On May 10th, tropical storm Ana—the first named storm of this year’s North Atlantic hurricane season—made landfall along the Carolina coast. NASA scientists took the opportunity to observe the storm’s wind dynamics with one of their newest toys and produced this spectacular wind map while they were at it. » 5/18/15 12:12am Monday 12:12am

The Republican SOTU Live-Stream Cut Obama's Remarks On Climate Change

President Barack Obama took climate change deniers to task during his State of the Union Address, mocking the "I'm not a scientist" refrain that has become common among Republicans in recent months. But much of Obama's criticism was cut from the Republican party's official live stream of the speech. » 1/21/15 3:20pm 1/21/15 3:20pm

Humanity Is In The Existential Danger Zone, Study Confirms

The Earth's climate has always changed. All species eventually become extinct. But a new study has brought into sharp relief the fact that humans have, in the context of geological timescales, produced near instantaneous planetary-scale disruption. We are sowing the seeds of havoc on the Earth, it suggests, and the… » 1/18/15 11:30am 1/18/15 11:30am

A Relentless Blitz Of Small Rocks Obliterated Earth's Early Atmosphere

The Earth went through some tough times after its formation 4.5 billion years ago. Geochemical evidence indicates that its atmosphere was obliterated at least twice. One theory is that a large object from space smashed into our planet's surface, but a new study suggests it was actually thousands of small impacts. » 12/02/14 1:20pm 12/02/14 1:20pm

An "Impenetrable Barrier" Protects The Earth From Killer Electrons

It appears that our planet's built-in force field is much stronger than we thought. Scientists studying the Van Allen belts have discovered the presence of a nearly impenetrable barrier that prevents some of the fastest and most powerful "ultrarelativistic" electrons from reaching the surface. » 11/27/14 1:00pm 11/27/14 1:00pm
