Balloon over Titan and the foundations of 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 change in the Earth’s orbit, many scientists believe, transformed the “Green Sahara” into what is now the largest desert on the planet. While scientists are still trying to find out if the slow shift in orbit had rapid or gradual environmental consequences, they say Earth’s orbit will continue to change today and into the future. See article.
g Life - Forget little green men on Mars - aliens could be right here on Earth, a leading scientist has claimed. See article. This article is from 2009.
g Cosmicus - The next mission to Titan could provide a bird's-eye view of that intriguing Saturn moon, if scientists agree to send a balloon or blimp cruising through its skies for months. See article.
g Learning - That glittering star topping your Christmas tree isn't there just to look pretty – it represents the Star of Bethlehem, which glowed overhead when Jesus was born, according to the Bible. But some scientists believe the star was not a star at all, but three planets. See article.
g Aftermath - Over the past two decades, advances in a number of scientific disciplines have helped us better understand the nature and evolution of life on Earth. These scientific developments also have helped lay the foundation for astrobiology, opening up new possibilities for the existence of life in the Solar System and beyond. See article. This article is from 2001.
