Heritage of Earth’s water gives rise to hopes of life on other planets

A pioneering new study has shown that water found on Earth predates the formation of the sun – raising hopes that life could exist on exoplanets, the planets orbiting other stars in our galaxy.

The ground-breaking research set out to discover the origin of the water that was deposited on the Earth as it formed.

It found that a significant fraction of water found on Earth, and across our solar system, predates the formation of the sun. By showing that water is ‘inherited’ from the environment when a star is born, the international team of scientists believe other exoplanetary systems also had access to an abundance of water during their own formation.

*A UA astronomy research team was awarded a $600,000 grant for technology development under NASA’s Explorer mission program. The mission would send a space telescope high above Earth’s surface to watch how planets around other stars form and evolve.*

There has been much talk about possible Earth-like planets discovered by the Kepler space telescope launched just two years ago in the search for life outside our solar system. So far, it has discovered more than 2,326 possible Earth-like planets, and the number keeps growing.

At the University of Arizona’s Steward Observatory, an astronomy research team is asking questions such as, “How do planets like those found by Kepler arise? What materials are present during their initial formation? How do they evolve?” (more…)

UChicago Launches Search for Distant Worlds

Since 1995, scientists have discovered approximately 600 planets around other stars, including 50 planets last month alone, and one that orbits two stars, like Tatooine in Star Wars. Detection of the first Earthlike planet remains elusive, however, and now the University of Chicago joins the search with the addition of Jacob Bean and Daniel Fabrycky to the faculty. (more…)
