Is anybody home? Astronomers have pinpointed two planets orbiting a nearby star that meet pretty much every requirement for supporting life. They're almost exactly the same mass as the Earth, they are billions of years old (which means life could have had time to evolve), and they're orbiting their star at a distance that would support things like water flow and habitable temperatures.The two planets orbit Teegarden's star, an ancient star that is only 12-light-years away from the Earth.

The Duma is widely expected to approve his appointment. The 53-year-old Mishustin would replace Dmitry Medvedev, who was Putin's longtime ally and Russia's prime minister for the past eight years. Medvedev resigned Wednesday together with the whole Cabinet after Putin proposed sweeping changes to the constitution that could keep him in power well past the end of his term in 2024. 726
