NASA Funding Flows to Seven Small Businesses in Arizona

NASA has selected its 2018 crop of small businesses to receive funding supporting innovation research and technology transfer, with seven awards going to Arizona.

The Small Business Innovation Research (SBIR) program and Small Business Technology Transfer (STTR) contracts, which total $43.5 million nationally among 348 awardees, support projects that promise to benefit both NASA’s mission and the U.S. economy.

Lucky Amateur Captures Key Supernova Moments on Film

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.

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.

Energy-Efficient Lights Could be Making Light Pollution Worse

City lights drive back the night a little more each year, disrupting ecological cycles, and the switch from orange-yellow sodium lights to bluish-white LEDs might be making the problem worse.

We’re Not in Phoenix Anymore: How Radio Signals “Skipped” All the Way to Kansas

Yes, it’s that exciting.

Unlike AM signals, FM is confined to line-of-sight, so Phoenix’s KBAQ radio station doesn’t typically reach much beyond the Valley of the Sun, let alone to a Volkswagen Beetle 875 miles away. So it’s no wonder that Ken Baker of the Radio Kansas Network was surprised to see what resolved on his HD tuner that day.
