Scientists have completed the largest search to date for signs of life outside of our solar system. Using a radio telescope in Australia, scientists studied around 10.3 million stars. They didn’ t find life—not yet, at least. Researchers were looking for communications signals that may come from alien beings. The search was 100 times deeper and broader than ever before, and it involved few stars in the universe. Ten million stars do seem like a lot. However, there are around 100 billion stars in the Milky Way galaxy. So they have only looked at about 0.001% of our galaxy.
