The depths of space are much closer to home following the University of Alberta's acquisition of a meteorite that is the only one of its kind known to exist on Earth! What makes it so rare? The meteorite is 'pristine' -- that is, still frozen and uncontaminated -- and so provides an invaluable preserved record of material from when the solar system formed 4.57 billion years ago.

The Tagish Lake Meteorite is carbonaceous chondrite and, as such, represents primitive material from which the solar system formed. The meteorite is rich in pre-solar grains -- grains from other stars that were present near our solar system when it formed. The meteorite contains primitive molecules that are the building blocks of the components necessary for life. The pristine state of the meteorite makes it especially important for scientific research purposes; it presents an unprecedented opportunity to look for extraterrestrial ices.

The University of Alberta, through the Department of Museums and Collections Services and the Department of Earth and Atmospheric Sciences, led a consortium of partners that, together, acquired the pristine samples for mutual research and heritage interests. These partners include the Department of Canadian Heritage, the Royal Ontario Museum, Natural Resources Canada, and the Canadian Space Agency.

Dr. Christopher Herd, the Curator of the University of Alberta Meteorite Collection, will lead future research on the University's approximately 650 grams of this unique extraterrestrial rock.

"What's fascinating about the Tagish Lake Meteorite is that it enables us to probe the farthest reaches of our solar system by studying material that has come to us,' noted Dr. Herd, a professor of Earth and Atmospheric Sciences at the University of Alberta. The study of the meteorite has the potential for revolutionizing our understanding of the formation of the solar system. The meteorite fell on the frozen surface of Tagish Lake, northern BC, in Canada on January 18, 2000.

The University of Alberta is home to Canada's second-largest meteorite collection. Most recently, Dr. Herd has established a research program in the study of meteorites from Mars; research in meteorites in the collection and others on loan to the University continues to this day. Expertise in other areas of space research reside on campus ranging from the history of space exploration to the formation of dust devils on Mars, and spanning the humanities, engineering and the sciences.

Nasa Gives You An Excuse to Post a Selfie on Earth Day

TheStreet (Apr. 22, 2014) NASA is inviting all social media users to take a selfie of themselves alongside nature and to post it to Twitter, Facebook, Flickr, Instagram, or Google Plus with the hashtag #globalselfie. NASA's goal is to crowd-source a collection of snapshots of the earth, ground-up, that will be used to create one "unique mosaic of the Blue Marble." This image will be available to all in May. Since this is probably one of the few times posting a selfie to Twitter won't be embarrassing, we suggest you give it a go for a good cause. Video provided by TheStreet
