On Saturday I made the long drive from the Grand Canyon to find clear skies in Nevada for the Geminids meteor shower. I picked a remote location called Little Finland but underestimated the time it would take to get there, thankfully on the way was this location called Whitney Pockets. After a fantastic sunset and rainbows from the clearing storm I set up for my long night of shooting. I setup both the Fuji XT-1 and the X-E1, I ended up catching a lot more meteors with the X-E1 facing East in the early evening. Fortunately it was a beautiful calm night and I was able to lay outside in my sleeping bag watching the meteors for several hours before I dozed off.

In all I captured 24 meteors, I composited them all into one shot and corrected their rotation to match the radiant of the background image. Taken with a Rokinon 12mm f/2 at f/2 ISO 6400, 25s when the moon was down, and 15s when the moon rose. For the forgeground I used one light painted exposure.

New System Reveals How Our Brains and Bodies Change as We Fall Asleep

Full article at http://neurosciencenews.com/sleep-tracking-psychology-insomnia-1563/.

Combining behavioral and physiologic measures depicts gradual process, may help diagnose sleep disorders.

The research is in PLOS Computational Biology. (full open access)

Research: “Tracking the Sleep Onset Process: An Empirical Model of Behavioral and Physiological Dynamics” by Michael J. Prerau, Katie E. Hartnack, Gabriel Obregon-Henao, Aaron Sampson, Margaret Merlino, Karen Gannon, Matt T. Bianchi, Jeffrey M. Ellenbogen, and Patrick L. Purdon in PLOS Computational Biology. doi:10.1371/journal.pcbi.1003866 (http://dx.doi.org/10.1371/journal.pcbi.1003866)

Image: Sleep study participants are asked to squeeze a small ball with their hand in time with their breathing, and the force and timing of their motions are measured by the glove and by electrodes on a forearm muscle. By combining EEG brainwave data with information from the way squeezes decrease in frequency and strength as a participant falls asleep, investigators can now track the dynamic changes in brain and body during the sleep onset process.

The Sombrero Galaxy
http://21space.info/
http://21space.info/ NASA/ESA Hubble Space Telescope and NASA's Spitzer Space Telescope joined forces to create this striking composite image of one of the most popular sights in the universe. Messier 104 is commonly known as the Sombrero galaxy because in visible light, it resembles the broad-brimmed Mexican hat. However, in Spitzer's striking infrared view, the galaxy looks more like a "bull's eye."
Spitzer's full view shows the disk is warped, which is often the result of a gravitational encounter with another galaxy, and clumpy areas spotted in the far edges of the ring indicate young star-forming regions.
The Sombrero galaxy is located some 28 million light-years away. Viewed from Earth, it is just six degrees south of its equatorial plane. Spitzer detected infrared emission not only from the ring, but from the center of the galaxy too, where there is a huge black hole, believed to be a billion times more massive than our Sun.
The Spitzer picture is composed of four images taken at 3.6 (blue), 4.5 (green), 5.8 (orange), and 8.0 (red) microns. The contribution from starlight (measured at 3.6 microns) has been subtracted from the 5.8 and 8-micron images to enhance the visibility of the dust features.

If Saturn were as close to the Earth as the Moon is, this is how it would look.
