APOD 3.2

This image was taken in Antarctica in 2003. Two photographers traveled to the bottom of the world to see the complete solar eclipse. The image is a composite image to recreate what the human eye would have seen. The corona extends out beyond the shadow of the moon. To the right of the other photographer is an equipment bad and a collapsible chair. Some people really like eclipses.

APOD 3.1

This image is a time exposure of the sky during the Quadrantid Meteor Shower. The cistern structure lies above the buried Persian city of Qumis, known to the ancient Greeks as Hecatompylos. There are actually only two meteors in this picture, they go against the light trails of the stars, the brightest of which is actually not a star, but the planet Saturn. Time exposures are when the film is left to capture an image for an extended amount of time, and that's why the stars appear to move.

Sol

This image of the Sun is composed of four different layers of ultraviolet light.
This is a picture of God holding the Sun shortly after it's creation. Circa 5,000,000,000 BC.
This picture is a composite image taken at ultraviolet wavelengths from 171-284 Ã…ngstroms
This is a picture of a coronal mass ejection taken in the x-ray wavelength.
Another image of the Sun taken in the x-ray spectrum.
This gif shows a coronal mass ejection with the sun blocked out (represented by the smaller circle).

Observation (December-January)

I've been observing every night, weather allowing, and I've come to love the winter sky. I think that the Winter Hexagon (Sirius, Betelgeuse, Procyon, Castor, Pollux, Capella, and Aldebaran) is the coolest part of the sky, and I look at it all the time. The fall sky is kind of boring, but Pegasus and Aries are cool. Cassiopeia and Perseus are cool, but where I moved to is too bright at night to see Cepheus or Camelopardalis. Anyway, stars are cool, so tune in next time for more observations! :D
