Passage Three

Our Milky Way galaxy could contain up to 1 billion Earth-like planets capable of supporting life, scientists announced last week.

The theoretical abundance of habitable worlds among the estimated 200 billion stars of our home galaxy suggests that more powerful telescopes might glimpse the faint signature of far-off planet, proving that, in size and temperature at least, we are not alone in the universe.

Solar systems such as Earth’s, in which planets orbit a star, have been discovered. Astronomers have identified almost 100 planets in orbit around other suns. All are enormous, and of the same gaseous make-up as Jupiter.

Barrie Jones of the Open University in UK and his colleague Nick Sleep have worked out how to predict which of the newly discovered solar systems is likely to harbor Earth-like planets.

Using a computer, they have created mathematical models of planetary systems and seeded them with hypothetical Earths in “Goldilocks zone” orbits, where it is neither too hot too cold to support life.

The computer simulates which of these model Earths is likely to be kicked out of its temperature orbit by gravitational effects of the monster planets, and which is likely to survive. The solar system most like ours discovered so far is 51 light years away, at the star 47 Ursae Majoris, near the group of stars known as the Great Bear.

Astronomers have discovered two planets orbiting 47 Ursae Majoris----One is two and half times the size of Jupiter, the other slightly smaller. Both planets are relatively close to the Goldilocks zone, which is further out than ours because 47 Ursae Majoris is older, hotter and brighter than the sun.

“It’s certainly a system worth exploring for an Earth-like planet and for life,” said Jones. The requirement for a life-supporting zone in any solar system is that water should be able to exist in a liquid state.

NASA and its European counterpart, ESA, plan to launch instruments in the next 10 years which could produce pictures of Earth-sized planets.

61. It is suggested in this passage that _______________

A scientists have found evidence to prove there are many Earth-like planets in our galaxy.
