Did glaciers lure wolves back to California?

More than 90 years after California’s last wolf was killed, a pack has been observed near Mt. Shasta. Are the mountain’s glaciers a reason the wolves chose this location?

Rediscovering a rare South Pacific nautilus

In July, scientists spotted a rare South Pacific nautilus – considered to be one of the rarest animals on Earth – for the first time in three decades.

On August 21, 2015 the Aqua satellite captured this image of the smoke from the fires on the west coast of the United States wafting eastward on the jet stream.  In this image the smoke is obscuring parts of Montana, North and South Dakota, Minnesota, and Wisconsin.  Residents of these states are on notice that sunsets will be much redder and more orange as long as the smoke lingers over their area. The reason? The size of the smoke particles is just right for filtering out other colors meaning that red, pink and orange colors can be seen more vividly in the sky.

Captures of elusive red sprites from ISS

Why are sprites elusive? It doesn’t help that they flash on millisecond timescales. Also, they’re above thunderstorms, usually blocked from view on the ground.
