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.

Zombie Satellite to Amateur Astronomer: “I’m Not Dead Yet”

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.

Arizona Fireball Captures Regional Attention

Phoenix CityCam caught the flash of light around 8:30 p.m. on Nov. 14, 2017. Image courtesy Phoenix.gov/CityCam.

Arizonans were treated to an unusual spectacle Tuesday night as a fireball flashed across the sky around 8:30 p.m.

The American Meteor Society received reports from six states describing the object, which flashed brighter than the full moon before quickly fizzling out.

Detecting Gravitational Waves from Prescott, Arizona

This year’s Nobel Prize in Physics was awarded to three men, but the detection of gravitational waves was the work of a thousand scientists and students — 10 of them from Embry-Riddle Aeronautical University in Prescott.

Mantle Mystery Yields to Diamond Vise

Improved imaging of the Earth’s interior has unlocked new subsurface mysteries, including an area 600 miles (1,000 kilometers) down where the mantle’s usual flow pattern changes.

Now, at a lab bench on the planet’s surface, a team of researchers might have found the reason why.
