A colleague shared this information with me and I can’t help but pass it on to you. Lewis and Clark Were Here is the title of an expedition by Maureen Oliver and Tony Fernandez in which they will be following the Lewis and Clark trail from the Pacific Northwest to St. Louis. They anticipate that their foot journey slated to begin in May will be completed in November. Thus I would estimate the South Dakota Portion of their trek to be in the fall. They will be documenting their trip with video, via facebook, their website (linked above) and twitter. This may be a great way for students to remain engaged with learning over the summer and perhaps a great field trip for those of you close to the Missouri River. I would bet Maureen and Tony would be more than willing to chat with students for a little while about their expedition and the similarities and differences between them and the Lewis and Clark expedition.

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.

Wow, thanks for picking up our story! We’d be more than happy to chat with students and teachers about our trip and the lessons we’re learning. We’re getting our maps posted to our website shortly so you can see where we’ll be passing through. There is contact information on there as well, so feel free to visit http://www.lewisandclarkwerehere.com and we’ll get it all set up. Thanks for mentioning it!
