If you haven’t been to www.thinkfinity.org recently, you might want to check out one of its content partner sites. ReadWriteThink has gone through a site redesign and I think you will love it. If you search the lessons, you will notice a new little feature where you can now select the state standards for that lesson!! So now each lesson in ReadWriteThink can be quickly aligned to SD Standards. They have a lot of other new features as well, so please visit the website and check it out. I would love to hear your comments about the features you find exciting and useful. Please comment.

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.
