I've been collecting postcards on and off since I was a kid - exchanging them while trading zines, buying them everytime I'm on vacation, and getting them from family members who went overseas. In January 2007 I discovered Swap-Bot, and from then on I started collecting more actively! Since then I also started to swap on Postcrossing and the Postcrossing Forums.

Three stellar Jets from Young Stars

Sunday, November 23, 2008


As part of the star formation process, gaseous jets shoot from new stars in the constellation Taurus (top left), near the Orion Nebula (top right), and at the edge of the Gum Nebula (bottom). The scale at the bottom of each image represents 93 billion miles, 1,000 times the distance between the Earth and the sun.
