Habitable worlds in our solar system and new trans-Neptunian objects

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 - With some clever science, astronomers have re-examined data archives from the Hubble Space Telescope and discovered 14 new trans-Neptunian objects. These objects rest beyond the orbit of Neptune and can teach us a great deal about the history of the Solar System and the materials that could have been delivered to the early Earth. See article.
g Intelligence - Quote of the Day: “I’m sure the universe is full of intelligent life. It’s just been too intelligent to come here.” – Arthur C. Clarke
g Cosmicus - An astrobiologist at NASA's Goddard Space Flight Center says the possibility of extraterrestrial life in our solar system is not limited to Mars; other "habitable" worlds might exist including the icy Moons of Jupiter and Saturn, known as Europa and Enceladus. The challenge for scientists and engineers in the next couple of decades, he says, will be to design miniaturized instruments and technologies capable of detecting the signatures of life in our own solar system and beyond. See webcast. This webcast is from 2009.
g Aftermath - Among scientists involved in the Search for Extraterrestrial Intelligence, it’s quite common to be focused on the future, ever mindful that it could take years, or even decades, to find a signal from otherworldly intelligence. But if historian Steve Dick has his way, astronomers will also turn their attention toward the past as they search for life beyond Earth — to discover the aftereffects of contact between two intelligent cultures. See article. Note: This article is from 2002.

I still think Europa is our best chance for life outside of Earth (in this solar system). But even that is phenomenal; if life is so common as to develop twice in the same Solar System....just imagine the possibilities...
