Scientists are seeking Earth-sized planets as potential homes for
extraterrestrial life, said Fressin, who reports the new findings in a
paper published online yesterday by the journal Nature.
One planet's diameter is only 3 per cent larger than Earth's, while the other's diameter is about nine-tenths that of Earth. They appear to be rocky, like our planet.
But they are too hot to contain life as we know it, with calculated temperatures of about 1,400 degrees and 800 degrees Fahrenheit (760 Celsius and 425 Celsius), he said. Any life found on another planet may not be intelligent; it could be bacteria or mold or some completely unknown form.
