Hello Folks,

If you have been trying to figure out why we received so much snow earlier this winter, you might want to check out the link listed below from the folks at NASA.  They discuss the reasons for our early snow dump as well as the deep cold temperatures and heavy snows now hitting Europe

I wanted to share a short video segment with you that was made by the BBC.  A student in the marine biology class at Cordova High School discovered it on the internet.  You might want to check it out......The things that happen in nature are truly amazing!

If you like seeing images that space craft have taken while looking down on Earth from space, you might like to check out this recent NASA link listed below.... The image was taken at night from the International Space Station and shows the lights of several major cities in the Midwestern U.S, lightning from a thunder storm and aurora in the Earth's upper atmosphere.  If you look carefully in the upper part of the photo, you can see the underside of the International Space Station too......Allen

I thought you might like to check out this new type of 3D technology.  I did some research on this subject and this video is legitimate!  Pretty amazing technology we have available these days!  At just $5,000.00 and weighing less than 100 pounds, this could be your next printer!

Just click on the link below and start the short video!

COMET ENCOUNTER UPDATE: NASA's Deep Impact (EPOXI) probe has just completed its 435 mile flyby of Comet Hartley 2's nucleus. The spacecraft has turned its high-gain antenna toward Earth and data are being transmitted to mission control at JPL. The first raw images have just arrived and, even without processing, they are spectacular:



Fluke Footage Catches Whale In the Act                 http://www.sciencefriday.com/videos/watch/10225
 
For years, longline fishermen in Alaska have complained that whales have been stealing their sablefish catch. A team of researchers, including Aaron Thode, Delphine Mathias and Jan Straley, mounted a video camera to a fishing line and caught a sperm whale stealing. Thode, a research scientist at Scripps Institution of Oceanography, explains what the video reveals about whale behavior.

Sam Easterson has refined the art of the critter cam. He is the curator of the Museum of Animal Perspectives--an online repository of remotely-sensed wildlife imagery. All the footage comes from cameras implanted in the landscape or strapped to the backs of animals.

Spectacular Aurora Shot!!

 Summary: Solar activity continues to increase after a two-year solar minimum that ranks among the century's deepest. The return of sunspots and a resurgent solar wind is good news for aurora watchers, who are seeing some of the best displays since 2006.

Photo by Grant Bisset was taken near Mt John Observatory, Lake Tekapo, New Zealand. 0806:24 UTC
Canon 5D, 35mm lens @ 2.8, for 20 sec ISO 1600  - "1st Aurora I have seen of this Solar Cycle".

Summertime doesn’t have to mean hours behind the lawn mower, at least for shade-dwellers. David Benner, horticulturist and moss enthusiast, cut grass out of his life 40 years ago. In its place, he cultivated moss. He now has 25 different species of moss growing on his property near New Hope, Pa. Benner, whose son Al Benner runs Moss Acres, shares tips for moss cultivation.

Hello Everyone,

If you ever wondered just how big the International Space Station really is, you might want to take a look at this short video provided by the folks at "Best of Science", it is truly amazing....
Just click on the link below and once it starts to play, you might want to pause it for a few minutes to let it buffer.  The video won't start and stop on you if you let it buffer long enough!

Hello Everyone,
 
The satellite image listed below is from NASA and shows how much the oil from the Gulf oil spill has spread out over the area.  Considering how little of the oil has actually washed ashore, it looks like it will be around for a very long time.

Aurora Australis Observed from the International Space Station



There is a great photo attached to this email of a satellite image taken over the CRD during the last big windstorm that records the combination of blowing dust and snow out into the GOA.  The link listed below will take you to the science center blog page where Dr. Rob Campbell explains a little about what is going on with a short informational article and higher resolution image of the event.

Total Lunar Eclipse Visible Across North America
By Allen Marquette

Did you catch the total lunar eclipse that occurred the other night?  If you didn’t, you missed an amazing event that does not occur too often on winter solstice.  The event was visible across North America and started in Alaska at 9:33pm Alaska time, and lasted until 1:01am Tuesday morning.  Totality or when the Moon, Earth and Sun align perfectly occurred at 11:17pm.  If you did get to see the eclipse and wondered why the moon took on the ruddy umber color during totality, it’s because the sunlight passing through the Earth’s atmosphere was refracted or bent by the atmosphere causing the light to change or shift color and give the moon that burnt look.  The last time a total lunar eclipse occurred on winter solstice was 372 years ago in 1638!  But if you did miss the total lunar eclipse, you can catch it next time when it occurs on December 21, 2094.  That’s only 84 years from now!
