It has been a long several months, but we are rewarding ourselves with a vacation. Tomorrow night the family is heading to Michigan to visit and relax. Jacki is going to be flying in on Sunday and we are all staying at Jess’ dads place. Jess’ dad has horse and a pool so we should have a good time. When we get back Grandma Betty will be in town for Brians wedding. If we have highspeed internet will post pictures through out the week.

A Chameleon Sky
 The sands of time are running out for the central star of this the Hourglass Nebula. With its nuclear fuel exhausted, this brief, spectacular, closing phase of a sun-like star's life occurs as its outer layers are ejected and its core becomes a cooling, fading white dwarf. In 1995, astronomers used the Hubble Space Telescope to make a series of images of planetary nebulae, including the one above. Here, delicate rings of colorful glowing gas (nitrogen-red, hydrogen-green, and oxygen-blue) outline the tenuous walls of the 'hourglass.' The unprecedented sharpness of Hubble's images revealed surprising details of the nebula ejection process and may resolve the outstanding mystery of the variety of complex shapes and symmetries of planetary nebulae.
