Mullfoto of the Day
Out the back window of our house on Lake Buel, just outside Great Barrington, Massachusetts where I was blessed to spend Thanksgiving with my family.
Catchy Caption of the Day
Actual Caption:
This NASA Hubble Space Telescope image shows Mars in 2005. Indian space scientists plan to send an unmanned mission to Mars by 2013 to look for evidence of life, a news report said.
Ok. Another photo of a body in space. A little sharper than mine. Mine was taken with a Canon PowerShot S700 which cost about $400. The Hubble cost $2 BILLION.
