Earth-size stars and alien oceans – an astronomer explains the case for life around white dwarfs
Earth-size stars and alien oceans – an astronomer explains the case for life around white dwarfs Astronomer Juliette Becker explains that life could exist on planets orbiting white dwarfs, which are small, dense stars that form when a star like our Sun exhausts its fuel and expands into a red giant phase. White dwarfs are […]

New model helps to figure out which distant planets may host life
New model helps to figure out which distant planets may host life The search for life beyond Earth is challenging due to the difficulty in interpreting biosignatures and determining habitability. A new approach called the quantitative habitability framework has been developed to identify potentially habitable planets or moons and interpret potential biosignatures by modeling how […]

Gas hunt may reveal signs of alien life on distant planets
Gas hunt may reveal signs of alien life on distant planets Researchers have identified a promising new way to detect life on faraway planets. Their approach hinges on worlds that look nothing like Earth and gases rarely considered in the search for extraterrestrials. In a new Astrophysical Journal Letters paper, the researchers describe these gases, […]
