Exoplanet K2-18b is garnering a lot of attention. James Webb Space Telescope spectroscopy shows it has carbon and methane in its atmosphere. Those results, along with other observations, suggest the planet could be a long-hypothesized ...

In the search for potentially life-supporting exoplanets, liquid water is the key indicator. Life on Earth requires liquid water, and scientists strongly believe the same is true elsewhere. But from a great distance, it's ...

Venus, often called Earth's "evil twin" planet, formed closer to the sun and has since evolved quite differently from our own planet. It has a "runaway" greenhouse effect (meaning heat is completely trapped), a thick carbon-dioxide-rich ...
