Beautiful Pictures from National Geographic ...

Psalm 19:1-7, " 1The heavens keep telling the wonders of God,
and the skies declare what he has done.  2Each day informs
the following day; each night announces to the next.
3They don't speak a word, and there is never the sound of a voice.
4Yet their message reaches all the earth, and it travels around the world.
In the heavens a tent is set up for the sun. 5It rises like a bridegroom
and gets ready like a hero eager to run a race.  6It travels all the way
across the sky.  Nothing hides from its heat. 7The Law of the LORD is perfect;
it gives us new life.  His teachings last forever, and they give wisdom
to ordinary people.

A dazzling green aurora frames the arc of the Milky Way over Jökulsárlón, the largest glacier lake in Iceland, on March 10. The picture is a first-prize winner in the Second International Earth and Sky Photo Contest's "Beauty of the Night Sky" category.
Organized by astronomy-education projects The World at Night (TWAN) and Global Astronomy Month, the contest honors pictures that meet one of two criteria: "either to impress people on how important and amazing the starry sky is, or to impress people on how bad the problem of light pollution has become." In total, ten winners were announced May 9 in either the "Beauty of the Night Sky" or "Against the Lights" category.
To achieve the contest goals, organizers asked for "landscape astrophotography"—pictures of world landmarks against the night sky. This style "brings Earth and sky into one frame, and it's a bridge between the night sky and the ... environment," TWAN founder and contest judge Babak Tafreshi said in an email to National Geographic News.
"If we considered dark, starry skies a part of nature and our living world heritage, then we would try to preserve it like the other parts of nature."

Starry sky over the Austrian Alps picture, a winner in the 2nd International Earth and Sky Photo Contest on Dark Skies Importance
1st Place, "Against the Lights" Category

Twinkling stars over the Austrian Alps compete against the bright glow of a mist-covered town near Lake Traunsee in a February 17, 2010, picture.
Overall, images in the "Against the Light" category "try to display how the beauties of the night sky are being vanished away by increasing lights in our modern life," TWAN's Tafreshi said. "Many of these lights are either not directed toward the ground in the right way or not necessary in those locations."
This picture of the Alps impressed the contest judges because it "has a very good balance between the starry sky and the lights," Tafreshi said. "Sky is affected partly by those village lights but not vanished away. So the beauty of nature exists above the lights."

A 3-D image of an active sun shows sunspots and "wonderful active regions in exquisite detail," according to NASA's Solar Dynamics Observatory. (See where you can get 3-D glasses to better appreciate this image.)

A powerful sun storm—associated with the second biggest solar flare of the current 11-year sun cycle—hit Earth last week.

Aurora Over Iceland

An aurora arches over Hveragerdi, Iceland, in a photo recently submitted to National Geographic's My Shot.
Auroras occur when large numbers of charged particles from the sun encounter Earth's magnetic shield. Most of these particles get corralled toward the Poles, where they slam into atmospheric gases such as nitrogen and oxygen.
