In the path of totality of the August 2017 total solar eclipse, bees stopped flying, says a study. “It was like ‘lights out’ at summer camp.”
The South Taurid meteor shower rarely produces more than 5 meteors per hour, but it’s been known to produce fireballs. The shower is long-running. Watch for these meteors in October and November.

by Bill Allen. Thanks, Bill! By all reports, this shower has been amazing in 2015.

Astronomers thought Alpha Centauri was the closest star to Earth. Then they found a smaller, fainter star that’s even closer. They named it Proxima, which means “nearest.”

Many people report seeing earthshine on a waxing crescent moon. That’s when the darkened portion of the crescent glows dimly with light reflected from Earth.

Just because you don’t have the flu doesn’t mean that your aren’t teeming with viruses inside and out. But what are all these viruses doing, if they aren’t making you sick?

For the 1st time, astronomers have detected the faint radio afterglow of a ghost explosion – a kind of cosmic sonic boom – possibly the result of a weird kind of gamma-ray burst.
Artist's concept of a Gamma-Ray Burst after a massive explosion of a star. The two beams of gamma-rays are difficult to detect unless one of them is oriented toward Earth. Such a powerful occurrence is thought to be the cause of the "ghost explosion" where a faint "radio glow" can still be detected long after the event itself. Image via NRAO.
Voyager 2, launched in 1977, is now about 11 billion miles (17.7 billion km) from Earth. NASA says the spacecraft has detected an increase in cosmic rays, which might mean it’s close to becoming only the 2nd human-made object, after Voyager 1, to enter interstellar space.
This graphic shows the position of the Voyager 1 and Voyager 2 probes relative to the heliosphere, a protective bubble created by the Sun that extends well past the orbit of Pluto. Voyager 1 crossed the heliopause, or the edge of the heliosphere, in 2012. Voyager 2 is still in the heliosheath, or the outermost part of the heliosphere. Image via NASA/JPL-Caltech.
Humpback whales have ever-changing and evolving songs. But a new study of whales in Alaska shows their repertoire of calls – including growls, trumpets, and ahoogas – remains more stable. Why?
