The wildfires raging across Washington, Oregon and Idaho are not only bringing a dense, smoky haze to much of the area just to the east of the Cascades, but its effects are being felt over 1,000 miles away across the Upper Midwest.
We're all likely familiar with what a hail storm looks like from the ground -- around here, it's as if someone dumped gazillions of frozen peas on the ground... if the peas were made of ice.
But have you ever seen a big hailstorm from the top? (And I mean BIG hailstorm, not the "what passes for big in Portland but Midwesterners and East Coasties laugh as child's play" hailstorm? The kind that could be disguised as a golf ball or, when you're really in for it, a softball?)
Tuesday was a big day in the science community with the release of a major federal scientific report on climate change.
The 840-page report, several years in the making, looks at regional and state-level effects of global warming, compared with recent reports from the United Nations that lumped all of North America together. A draft of the report was released in January 2013, but this version has been reviewed by more scientists, the National Academy of Science and 13 government agencies and had public comment.
It is written in a bit more simple language so people could realize "that there's a new source of risk in their lives," said study lead author Gary Yohe of Wesleyan University in Connecticut.
An outdoor and astronomy enthusiast, Jensen has developed a narrative time lapse video that shows what humanity's efforts to erase the nighttime darkness in our cities has taken on the night sky, and the interaction (or lack thereof) that we are having with starry skies.
"Escape the Light Dome" introduces us to our world where we are blinding ourselves to a view of the universe.
Our sunrises and sunsets are legendary around here, but how would you like to see all the sunrises and sunsets on Earth -- at the same time! And it doesn't even require a trip to outer space.
Instead, the moon is going to essentially turn into an astronomical version of a projection screen as we get the first of four consecutive lunar eclipses over the next two years.
Even though the moon will be in the Earth's shadow, it should appear a bit colorful, some shade of red or orange. That's from light around the edges of the Earth - essentially all the sunrises and sunsets at the moment - splashing on the lunar surface and faintly lighting up the moon, said Alan MacRobert, senior editor at Sky & Telescope magazine.
