2009 Leonid Meteor
2009 Leonid Meteor, upload feito originalmente por Navicore
From 2:20am at the peak of the 2009 Leonid Meteor Shower. The radiant seems correct for Leo rising in the east. There is a rare amount of meteor detail in this shot. A particle streaks ahead of an awesome double afterglow and colorful train.
ISO 1600, K20D with an old Super Takumar m42 50mm 1:1.4 open all the way for 6 seconds and continuous.
I didn't crop or reframe the photo at all. The train even hung around for the the next exposure that started over 6 seconds later.
50mm isn't that big a field. I was about to switch to a much wider but slower lens. Glad I didn't, it is like the thing is posing for the 50mm.

mercury
Recent images from the robotic MESSENGER spacecraft that flew by Mercury last October show previously uncharted regions of Mercury that have large craters with an internal smoothness similar to the maria on Earth's own Moon. Therefore, like our Moon's maria, these craters on Mercury are thought to have been flooded by lava floes that are old but not as old as the surrounding more highly cratered surface. The above image mosaic of the western limb of Mercury was created by MESSENGER as it approached the Solar System's innermost planet last October. Old and heavily textured terrain runs across much of the image bottom, while across the middle left lies comparatively smooth impact basins where small craters may appear similar at first to protruding hills. MESSENGER will buzz past Mercury again later this year before entering orbit in 2011.

Busy Moon
Half an hour after Prometheus tore into Saturn's F ring, Cassini snapped this image just as the moon was creating a new streamer in the ring. The dark pattern shaped like an upside down check mark in the lower left of the image is Prometheus and its shadow. The potato shaped moon can just be seen coming back out of the ring.
The moon’s handiwork also is apparent in two previous streamer-channel formations on the right of the image. The darkest streamer-channel stretching from the top right to the center of the image shows Prometheus’ previous apoapse passage about 15 hours earlier. A fainter, even earlier channel extends to the edge of the image.
Prometheus (86 kilometers, 53 miles across) dips into the inner edge of the F ring when it reaches apoapse, its farthest point from Saturn. At apoapse, the moon’s gravity pulls out particles of the ring into a streamer. As Prometheus moves back toward periapse -- its orbit's closest point to the planet -- the streamer gets longer. Then, as Prometheus moves back toward apoapse, the streamer breaks apart which results in a dark channel. This streamer-channel cycle repeats once every orbit with the streamer-channel features being streamers during Prometheus periapse and channels during Prometheus apoapse.

The Most Distant Object Yet Discovered in the Universe
ESO's Very Large Telescope has shown that a faint gamma-ray burst detected last Thursday is the signature of the explosion of the earliest, most distant known object in the Universe (a redshift of 8.2). The explosion apparently took place more than 13 billion years ago, only about 600 million years after the Big Bang.

The Zone
On 26 April 1986 01:23:45 a.m. reactor number four at the Chernobyl plant, near Pripyat in the Ukrainian Soviet Socialist Republic, exploded. Further explosions and the resulting fire sent a plume of highly radioactive fallout into the atmosphere and over an extensive geographical area. Four hundred times more fallout was released than had been by the atomic bombing of Hiroshima
Bow Shock
A bow shock is created in space when two streams of gas collide. The young star LL Ori Emits a solar wind, a stream of charged particles moving rapidly outward from the star. The material in the wind collides with the gas evaporating away from the center of the Orion Nebula, creating the crescent-shaped collision area in the image.
