How water came to Earth and high school students study astrobiology

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Abodes - A new study shows that frequent meteorite impacts during an early period of the solar system known as the 'Late Heavy Bombardment' may have furnished the Earth and other planets like Mars with liquid water. By providing a source of water for the Earth's oceans, these impacts could have helped to make the early earth habitable. See article.
g Life - Quote of the Day: "There is grandeur in this view of life, ..., from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved." - Charles Darwin, closing sentence in On the Origin of Species (1859)
g Cosmicus - A British space expert believes astronauts should be sent to live on Mars for good - and asked to take part in a Big Brother-style TV show. See article.
g Learning - For 14 years, NASA has been working with Lassen Volcanic National Park administration and northern California students to study how the park's mix of snow, volcanoes and flowing water have affected the park's geology and microbiotic life. See article.
g Imagining - Here’s an interesting Web site: FAQ about Star Trek aliens. Though light on evolutionary origin, it’s questions (and answers) often point toward the need for writers to consider that issue.
g Aftermath - As SETI's scientists plan for their first contact with other worlds, who better to consult with than anthropologists, who specialize in encounters with exotic cultures? And thus, over the past several years the SETI Institute has repeatedly brought together anthropologists and scholars from other disciplines, in an attempt to bridge the gap between humans and extraterrestrials. See article. Note: This article is from 2007.
