Exoplanets like Earth have been discovered but not all Earth-like planets are equal when it comes to alien life.

We don’t usually get too in-depth with science coverage here at Digital Trends, but this breakthrough certainly deserves mention: NASA announced today that it has confirmed the discovery of the first ...

First-year students in Rochester Institute of Technology’s Science Exploration Program are reproducing a slice of life in their lab that might exist on the seven Earth-like planets recently discovered ...

An illustration shows what exoplanet K2-18b might look like based on data from NASA's James Webb Space Telescope. K2-18b is 8.6 times as massive as Earth, orbits the cool dwarf star K2-18 in the ...

"Are we alone?" This ancient question has occupied humanity's mind for a long time. In 1995, the discovery of the first exoplanet orbiting a sun-like star opened the door to exploring this profound ...

WASHINGTON — An Earth-sized planet in its star's habitable zone has been discovered in data from NASA’s Kepler space telescope. NASA says the newly found exoplanet is the closest to Earth in size and ...

K2-18b resides within the habitable zone of its star, making the presence of liquid water and thus life possible. Using the James Webb Space Telescope, researchers detected molecules in K2-18b's ...

— -- Astronomers on Monday reported the discovery of an Earth-like planet outside the solar system whose size and distance from its own star put it in the "habitable" zone and make for a surface ...

Some exoplanets, like the one shown in this illustration, may have atmospheres that could make them potentially suitable for life. NASA/JPL-Caltech via AP When astronomers search for planets that ...

Within a few dozen light years of the Sun, the sky is crowded with stars that could, in principle, host living worlds. I want ...
