Galaxy M81 2B Ties
This galaxy was first descovered by Johann Elert Bode in 1774 and is one of the easiest to see by amateur astronomers because of it's unususal brightness in the night sky. Recent obervations have determined that M81 may contain very little dark matter compared to most galaxies. Photo courtesy NASA.

Cat's Eye Nebula Card
The Cat's Eye Nebula (NGC 6543, Caldwell 6) is a planetary nebula in the constellation of Draco. Structurally, it is one of the most complex nebulae known, with high-resolution Hubble Space Telescope observations revealing remarkable structures such as knots, jets, bubbles and sinewy arc-like features. In the center of the Cat's Eye there is a bright and hot star; around 1000 years ago this star lost its outer envelope, producing the nebula. It was discovered by William Herschel on February 15, 1786, and was the first planetary nebula whose spectrum was investigated by the English amateur astronomer William Huggins in 1864. The results of the latter investigation demonstrated for the first time that planetary nebulae consist of hot gases, but not stars. Currently the nebula has been observed across the full electromagnetic spectrum, from far-infrared to X-rays. Modern studies reveal several mysteries. The intricacy of the structure may be caused in part by material ejected from a binary central star, but as yet, there is no direct evidence that the central star has a companion. Also, measurements of chemical abundances reveal a large discrepancy between measurements done by two different methods, the cause of which is uncertain. Hubble Telescope observations revealed a number of faint rings around the Eye, which are spherical shells ejected by the central star in the distant past. The exact mechanism of those ejections, however, is unclear.
Helix Nebula Business Card
“The Helix is a planetary nebula, the glowing gaseous envelope expelled by a dying, sun-like star. The Helix resembles a simple doughnut as seen from Earth. But looks can be deceiving. New evidence suggests that the Helix consists of two gaseous disks nearly perpendicular to each other.”(qtd. from HubbleSite.org NewsCenter release STScI-2004-32)Credit: NASA, ESA, C.R.

Carl Sagan is my Homeboy (Full Color) Tee Shirts
“Carl Sagan is my homeboy”. A parody of the commonly seen Jesus Is My Homeboy shirts. Picture of the upper torso of Carl Sagan with caption Carl Sagan Is My Homeboy underneath. Show your love of science and disbelief in pseudoscience, pseudosciences in general, religion and religious dogma, spiritual mumbo jumbo, superstition, myths and mythology, and other related rational improbabilities all at once! Say it subtly, but proud… I am an atheist, just like Carl Sagan.

Antennae Galaxies, NGC 4038/4039 Poster
“The Antennae galaxies take their name from the long antenna-like “arms” extending far out from the nuclei of the two galaxies, best seen by ground-based telescopes. These “tidal tails” were formed during the initial encounter of the galaxies some 200 to 300 million years ago. They give us a preview of what may happen when our Milky Way galaxy will collide with the neighboring Andromeda galaxy in several billion years.”(qtd. from HubbleSite.org NewsCenter release STScI-2006-46)Credit: NASA, ESA, and the Hubble Heritage Team (STScI/AURA)-ESA/Hubble Collaboration
