Just fix your camera to a tripod and you too
can make an image of graceful
trails
traced by the stars as
planet Earth rotates on its axis.
Featured are the stars of Orion (right of center), brilliant Venus
rising (left) as bright star Sirius rises in the south (bottom center),
and a polar orbiting
Iridium satellite (upper left).
Beautiful dawn sky colors seem painted along the horizon.
This remarkable picture was constructed from 477 consecutive 30
second digital exposures recorded over 4.3 hours and later combined.
This striking composite
image follows the Sun's path through
the December Solstice day of 2005 in a beautiful blue
sky, looking down the
Tyrrhenian Sea
coast from Santa Severa toward Fiumicino, Italy.
The view covers about 115 degrees in 43 separate, well-planned
exposures from sunrise to sunset.
Dust from curious near-Earth asteroid 3200 Phaethon seems to fall from the constellation Gemini in this fish eye sky view.
Ninety percent of the houses on
Grenada were
damaged by the destructive force of
Hurricane Ivan.
At its peak,
Ivan was a
Category 5 hurricane,
the highest power category on the
Saffir-Simpson Scale,
and created sustained
winds
in excess of 200 kilometers per hour.
Ivan was the largest
hurricane to strike the US in 2004, and,
so far, the 10th most powerful in recorded history.
As it swirled in the
Atlantic Ocean,
the tremendous
eye of Hurricane Ivan was
photographed from above by the orbiting
International Space Station.
The name Ivan has now been retired from Atlantic Ocean use by the
World Meteorological Organization
Perhaps it's time to go inside. Such thoughts might occur to people witnessing the approach of an impressive shelf cloud. Shelf clouds are typically seen leading thunderstorms, although they may precede any well defined front of relatively cold air. Shelf clouds differ from roll clouds because shelf clouds are attached to a larger cloud system lurking above. Similarly, shelf clouds differ from wall clouds because wall clouds typically trail storm systems.
