NASA’s Dragonfly Mission Sets Sights on Titan’s Mysteries

When it descends through the thick golden haze on Saturn’s moon Titan, NASA’s Dragonfly rotorcraft will find eerily familiar terrain. Dunes wrap around Titan’s equator. Clouds drift across its skies. Rain drizzles. Rivers flow, forming canyons, lakes and seas.  But not everything is as familiar as it seems.

Will the Sun Ever Burn Out? We Asked a NASA Expert: Episode 60

Will the Sun ever burn out? Well, the Sun, just like the stars we see at night, is a star. It’s a giant ball of super hot hydrogen. Gravity squeezes it in and it creates energy, which is what makes the Sun shine. Eventually, it will use up all of that hydrogen. But in the […]

NASA Studies Reveal Hidden Secrets About Interiors of Moon, Vesta

Analyzing gravity data collected by spacecraft orbiting other worlds reveals groundbreaking insights about planetary structures without having to land on the surface. Although the Moon and the asteroid Vesta are very different, two NASA studies use the same technique to reveal new details about the interiors of both.

Webb’s Titan Forecast: Partly Cloudy With Occasional Methane Showers

Saturn’s moon Titan is an intriguing world cloaked in a yellowish, smoggy haze. Similar to Earth, the atmosphere is mostly nitrogen and has weather, including clouds and rain. Unlike Earth, whose weather is driven by evaporating and condensing water, frigid Titan has a methane cycle.

NASA’s Webb Reveals New Details, Mysteries in Jupiter’s Aurora

NASA’s James Webb Space Telescope has captured new details of the auroras on our solar system’s largest planet. The dancing lights observed on Jupiter are hundreds of times brighter than those seen on Earth. With Webb’s advanced sensitivity, astronomers have studied the phenomena to better understand Jupiter’s magnetosphere.

What NASA Is Learning from the Biggest Geomagnetic Storm in 20 Years

One year on, NASA scientists are still making huge discoveries about the largest geomagnetic storm to hit Earth in two decades, the Gannon storm. The findings are helping us better understand and prepare for the ways in which the Sun’s activity can affect us. One year ago today, representatives from NASA and about 30 other […]
