NBC’s Today Show host Matt Lauer and NBC News correspondent Natalie Morales are taking a jaunt over to the Sci-Fi Channel to host two specials for the genre cable network.

Matt will host “Countdown to Doomsday,” a serious look at the varying scenarios and possible catastrophies that could literally bring an end to life on Earth as we know it. Using special effects technology Lauer will review ten different possibilities such as global warming, pandemic outbreaks of viral or bacterial diseases and asteroid or comet collision into our planet. He will also discuss with various experts what, if anything, we can do to avert these extinction level events or ELE’s.

Morales will host a show of a different type called “Quest for Atlantis,” in which she will take a look at the various legends that surround the mythic city (or landmass) and the fabled flood or massive earthquake that brought Atlantis to its ultimate demise. Natalie will also look at the tale of Atlantis through the eyes of more recent developments and archeological findings.

“Countdown to Doomsday” will premiere on the Sci-Fi Channel on June 14, 2006 at 9PM ET/Pt, and “Quest for Atlantis” debuts July 9, 2006 at 9PM ET/PT.
