The seven Earth-size planets around the distant star TRAPPIST-1 are "tugging" on each other as they travel around their parent star.

TRAPPIST-1 Planets Could Hold 250 Times the Amount of Water as Earth’s Oceans

In what could be an important milestone for future farmers on Mars, two healthy baby worms were recently born in simulated Martian soil.

NASA is monitoring Tropical Storm Harvey as it moves back into the Gulf of Mexico this morning (Aug. 28) after causing heavy rains and severe flooding across Texas and Louisiana this past weekend.

NASA Tracks Harvey's Record Rainfall While Protecting James Webb Telescope

One day, our sun will become a red giant, growing so large that it will swallow Earth.

Observations of Red Supergiant Antares Shed Light on the Final Moments of Dying Stars

The celestial music released from the sun suggests that its outer layer has grown weaker over the years, according to new research from the United Kingdom.
