HD - NASA's Jet Propulsion Laboratory

NASA's Dawn spacecraft turned science fiction into science fact by using ion propulsion to explore the two largest bodies in the main asteroid belt, Vesta and Ceres. The mission will end in fall 2018, when the spacecraft runs out of hydrazine, which keeps it oriented and in communication with Earth.

September nights! Planets bright! Milky Way sights!!

Why are the tallest peaks in the solar system found on one of its smallest worlds? Like any planet, how Mars looks outside is tied to what goes on inside. Dig into planetary formation in this 60-second video from NASA's Jet Propulsion Laboratory.

Initially scheduled for a 2.5-year primary mission, NASA's Spitzer Space Telescope has gone far beyond its expected lifetime -- and is still going strong after 15 years.

What's the latest news from Mars? A global dust storm is starting to settle, but still obscures the Martian surface. Curiosity turns six and drills a new rock sample and InSight is more than halfway to Mars and has tested its instruments and cameras.

Dark moonless nights for the summer Perseid Meteor Shower!

Three of the world's largest radio telescopes team up to show a rare double asteroid. 2017 YE5 is only the fourth binary near-Earth asteroid ever observed in which the two bodies are roughly the same size, and not touching. This video shows radar images of the pair gathered by Goldstone Solar System Radar, Arecibo Observatory and Green Bank Observatory.

New research from the up-close Grand Finale orbits of NASA's Cassini mission shows a surprisingly powerful interaction of plasma waves moving from Saturn to its moon Enceladus.

A dust storm continues to envelop the Red Planet and Curiosity's labs are back in action.

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.
