earth’s chorus…

From the “Atlantic”:

Here’s What the Space Around Earth Sounds Like

One of NASA’s newest missions has recorded the radio waves coming from our magnetosphere. Musicians: Sample away.

Surrounding our planet are rings of plasma, part of Earth’s magnetosphere, which are pulsing with radio waves. Those waves are not audible to the human ear alone, but radio antennae can pick them up, and that’s just what an instrument — the Electric and Magnetic Field Instrument Suite and Integrated Science (EMFISIS) — on NASA’s recently launched Radiation Belt Storm Probes has done.

The noises, often picked up here on Earth by ham-radio operators, are called Earth’s “chorus” as they are reminiscent of a chorus of birds chirping in the early morning. So here’s your planet, singing its song into space. Musicians: Sample away.

Just a peak at what our brains are capable of?

scale of the universe…

Here you can interact with the impossibly large and fantastically miniscule. Move the slider bar and try to wrap your mind around the relative scale of things.

the most astounding fact…

Astrophysicist Dr. Neil DeGrasse Tyson was asked in an interview with TIME magazine, “What is the most astounding fact you can share with us about the Universe?” This is his answer.

flying over planet Earth…

Science educator James Drake built this amazing timelapse video from the perspective of the International Space Station as it flew over North and South America. He created this video by downloading a series of 600 photographs that were available online at the Gateway to Astronomy Photograph of Earth, and then stitching them together into a complete video. You can see more of James work at his blog: infinity imagined. [from Universe Today]

This movie begins over the Pacific Ocean and continues over North and South America before entering daylight near Antarctica. Visible cities, countries and landmarks include (in order) Vancouver Island, Victoria, Vancouver, Seattle, Portland, San Francisco, Los Angeles. Phoenix. Multiple cities in Texas, New Mexico and Mexico. Mexico City, the Gulf of Mexico, the Yucatan Peninsula, El Salvador, Lightning in the Pacific Ocean, Guatemala, Panama, Columbia, Ecuador, Peru, Chile, Lake Titicaca, and the Amazon. Also visible is the earths ionosphere (thin yellow line), a satellite (55sec) and the stars of our galaxy.

adjusting perspective…

Paying attention to facts about space and its contents can go a long way in expanding our perspective so we don’t see our personal challenges as so BIG.

A sample: “There are more stars than there are specks of sand on earth.”

wrapping mind around the Milky Way…

It’s mind-boggling (a good thing!) to try to comprehend the exquisite beauty and power evident in space:

touching the Face of God

In honor of the 25th anniversary of the Space Shuttle Challenger disaster, and in profound appreciation of those who dream so big as to take millions of us into the awe-inspiring vastness and beauty of space with them —

High Flight

Oh! I have slipped the surly bonds of earth
And danced the skies on laughter-silvered wings;
Sunward I’ve climbed, and joined the tumbling mirth
Of sun-split clouds – and done a hundred things
You have not dreamed of – wheeled and soared and swung
High in the sunlit silence. Hov’ring there
I’ve chased the shouting wind along, and flung
My eager craft through footless halls of air.
Up, up the long delirious, burning blue,
I’ve topped the windswept heights with easy grace
Where never lark, or even eagle flew –
And, while with silent lifting mind I’ve trod
The high untresspassed sanctity of space,
Put out my hand and touched the face of God.
