Astronomers recently discovered 72 new galaxies! Hmmm. Our solar system has 8 planets. Our Milky Way galaxy has 100 to 400 billion stars, each with their own solar system, which means 800 to 3 trillion planets. That means our search for extraterrestrial life includes over 56 trillion new planets! Researchers will soon be studying the planets for signs of aliens.
