An amateur astronomer from Rosario, Argentina, has accomplished an historic first: capturing the initial moments of a supernova explosion on film.

Although astronomers spot hundreds of supernovas each year, none had previously  spied the bright, brief moment when the shock wave first bursts out from the star’s interior — until now.

Toxic Brain Matter Can Harm Brain Months After a Stroke

For stroke survivors, brain injury doesn’t always stop when the stroke has passed. Now, researchers at University of Arizona and Stanford University School of Medicine have moved one step closer to understanding why.

An amateur astronomer has picked up signals from a satellite NASA gave up for dead more than decade ago.

Scott Tilley was scanning the skies for secret military satellites when he picked up a transmission from the Imager for Magnetopause-to-Aurora Global Exploration (IMAGE) satellite.

Global Warming and the Future of Wind Power

Alternative energy sources like wind offer a way to lessen a country’s carbon footprint. But global warming trends could soon change the way the wind blows.

As rapid arctic warming shrinks the heat gap between the North Pole and equator, Northern Hemisphere winds could lose some oomph — up to 40 percent over the next century, depending on region.
