On April 6, Artemis II officially surpassed Apollo 13's record of the furthest distance humans have ever gone beyond Earth. That previous record, which was set in 1970, was 248,655 miles.

Earth may have won a cosmic chemistry lottery. Researchers found that during the planet’s earliest formation, oxygen had to be in an extremely narrow “Goldilocks zone” for two life-essential elements,

TOI-4616 b is an Earth-sized exoplanet orbiting an M-dwarf that offers a strong benchmark for studying atmospheric loss and planetary evolution. Astronomers have identified a rocky exoplanet that may become an important reference point for future research.

Earth is full. In fact, its sustainable carrying capacity was overshot decades ago. That's the central message from a new scientific study finding that humans have pushed the planet far beyond its long-term limits.

On Wednesday, two days after their moon flyby, the crew of the Artemis II mission settled in for a day of preparation to return to Earth.
