I was blessed this year to have these delightful furbags join my household. May 2008 bring all of you much love, laughter and plushiness.
Happy New Year!!
Kittenz, astronomy, science, photography and other four-legged snarky stuff.
Jens Hackmann took this stunning picture of a lightning storm near the Weikerscheim Observatory; the 300 second exposure is enough to see the stars streak and the observatory lit up by ambient light. Sometimes, when it’s cloudy, observing is difficult… but you can still get incredible pictures.I agree with Plait, astronomy IS the most lovely science.
Some auroras can only be seen with a camera. They are called sub-visual and are too faint to be seen with the unaided eye. The reason is that the human eye only accumulates light for a fraction of a second at a time, while a camera shutter can be left open indefinitely. When photographing an already picturesque scene above Juneau, Alaska, USA, a camera caught green sub-visual aurora near the horizon. Auroras are sparked by energetic particles from the Sun impacting the magnetic environment around the Earth. Resultant energetic particles such as electrons and protons rain down near the Earth's poles and impact the air. The impacted air molecules temporarily lose electrons, and when oxygen molecules among them reacquire these electrons, they emit green light. Auroras are known to have many shapes and colors.But nevermind all that. Aurora's always make me think of Yukon Cornelius.
