NASA’s Lucy spacecraft is 6 days and less than 50 million miles (80 million km) away from its second close encounter with an asteroid; this time, the small main belt asteroid Donaldjohanson. Download high-resolution video and images from NASA’s Scientific Visualization Studio.NASA/Dan Gallagher This upcoming event represents a comprehensive “dress rehearsal” for Lucy’s main mission … Read more
Have we ever been to Uranus? The answer is simple, yes, but only once. The Voyager II spacecraft flew by the planet Uranus back in 1986, during a golden era when the Voyager spacecraft explored all four giant planets of our solar system. It revealed an extreme world, a planet that had been bowled over … Read more
An international team of astronomers using the NASA/ESA Hubble Space Telescope has made new measurements of Uranus’ interior rotation rate with a novel technique, achieving a level of accuracy 1,000 times greater than previous estimates. By analyzing more than a decade of Hubble observations of Uranus’ aurorae, researchers have refined the planet’s rotation period and … Read more
The ice-giant planet Uranus, which travels around the Sun tipped on its side, is a weird and mysterious world. Now, in an unprecedented study spanning two decades, researchers using NASA’s Hubble Space Telescope have uncovered new insights into the planet’s atmospheric composition and dynamics. This was possible only because of Hubble’s sharp resolution, spectral capabilities, … Read more
Long-sought auroral glow finally emerges under Webb’s powerful gaze For the first time, NASA’s James Webb Space Telescope has captured bright auroral activity on Neptune. Auroras occur when energetic particles, often originating from the Sun, become trapped in a planet’s magnetic field and eventually strike the upper atmosphere. The energy released during these collisions creates … Read more
Researchers analyzing pulverized rock onboard NASA’s Curiosity rover have found the largest organic compounds on the Red Planet to date. The finding, published Monday in the Proceedings of the National Academy of Sciences, suggests prebiotic chemistry may have advanced further on Mars than previously observed. Scientists probed an existing rock sample inside Curiosity’s Sample Analysis … Read more
Although NASA’s Lucy spacecraft’s upcoming encounter with the asteroid Donaldjohanson is primarily a mission rehearsal for later asteroid encounters, a new paper suggests that this small, main belt asteroid may have some surprises of its own. New modeling indicates that Donaldjohanson may have been formed about 150 million years ago when a larger parent asteroid … Read more
NASA’s Lucy spacecraft has its next flyby target, the small main belt asteroid Donaldjohanson, in its sights. By blinking between images captured by Lucy on Feb. 20 and 22, this animation shows the perceived motion of Donaldjohanson relative to the background stars as the spacecraft rapidly approaches the asteroid. Lucy will pass within 596 miles … Read more
Out of school time (OST) educators work with youth in afterschool, community, and camp programs. Science, Technology, Engineering, and Mathematics (STEM) learning in OST can be challenging for multiple reasons, including lack of materials and support for educators. The NASA Science Activation program’s PLANETS project – Planetary Learning that Advances the Nexus of Engineering, Technology, … Read more
That’s a great question. And it’s a question that NASA will seek to answer with the Europa Clipper spacecraft. Europa is a moon of Jupiter. It’s about the same size as Earth’s Moon, but its surface looks very different. The surface of Europa is covered with a layer of ice, and below that ice, we … Read more
