Have you noticed two bright objects in the sky getting closer together with each passing night? It’s Jupiter and Saturn doing a planetary dance that will result in the Great Conjunction on Dec. 21. On that day, Jupiter and Saturn will be right next to each other in the sky -- the closest they have... Read More

Citizen scientist Gerald Eichstädt made this composite image using data obtained by the JunoCam instrument during four of the Juno spacecraft’s close passes by Jupiter. The greatly exaggerated color is partially a result of combining many individual images to create this view.

Several years ago, planetary scientist Lynnae Quick began to wonder whether any of the more than 4,000 known planets beyond our solar system might resemble some of the watery moons around Jupiter and Saturn. Though some of these moons don’t have atmospheres and are covered in ice, they are... Read More

Life as we know it requires three ingredients: energy, organic molecules, and liquid water. Our search for life beyond Earth is a search for planets, dwarf planets, and moons that harbor substantial liquid water. We call these places “ocean worlds.”

Our new NASA solar system mission, #Dragonfly, will send a rotocraft-lander to explore Saturn's moon, Titan! Why Titan? This ocean world is unique in the solar system, with organic compounds that could teach us about the origin of life itself. Watch this special edition of NASA Science Live to... Read More

Lightning is beautiful and powerful, and has been observed on planets across the solar system.
Solar System, Mars, Planets of Our Solar System
July's night skies feature Mars opposition on the 27th, when Mars, Earth, and the Sun all line up, and Mars' closest approach to Earth since 2003 on the 31st. That means great Mars viewing, though the planet-wide Martian dust storm will make seeing details more difficult.

As the Juno spacecraft orbits Jupiter, new discoveries about the giant planet continue to be made.
Solar System, Planets of Our Solar System
When NASA’s Juno spacecraft recently flew over the poles of Jupiter, researchers were astonished, as if they had never seen a giant planet before.
And in a sense they hadn’t.
The pictures were unlike anything in the history of planetary exploration.
