But the sturdy plate — inscribed with far more than the poignant words of Limón — also has a twin that sits on our planet. The replica is at the Brand Library & Art Center in Glendale, California, and the simple fact that it exists invites us to ponder the peculiar gap between art and science, or lack thereof.

While the SETI Institute is investigating interstellar space for extraterrestrial life, we may find it in our own cosmic backyard. It is unlikely to be anything other than microbial life, but even that would be a seismic, perception-altering discovery.

NASA's Europa Clipper spacecraft launched from Florida's Kennedy Space Center on a nearly six-year mission to Jupiter to see if it's possible to sustain life that far into space.

The Europa Clipper launched Monday aboard a SpaceX Falcon Heavy rocket propelling it on a six-year journey to reach its namesake icy ocean world.

NASA just launched a spacecraft the size of a basketball court towards Jupiter's moon Europa. Here's what will happen over the next 10 years.

In the coming weeks, NASA's Europa Clipper will take off on a long journey to Jupiter's moon Europa. The icy moon could potentially host alien life — and there's only one way to find out.

A NASA spacecraft has set sail for Jupiter and its moon Europa, one of the best bets for finding life beyond Earth.

Ocean worlds like Europa are not only unique because they might be habitable, but they might be habitable today,” NASA’s Gina DiBraccio said on the eve

It won't land, but the robotic spacecraft will fly as close as 16 miles to the moon's frozen surface to probe oceans of liquid water beneath.

The spacecraft will be NASA's first dedicated to studying a distant ice-covered moon in our solar system to determine whether it could be habitable for life.
