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, […]
