Planetary Systems - NASA Science
2024年10月22日 · Planetary Systems. Our solar system consists of the Sun, whose gravity keeps everything from flying apart, eight planets, hundreds of moons, and billions of smaller bodies – from comets and asteroids to meteoroids and tiny bits of ice and rock.
Voyager - NASA Science
2024年12月9日 · Voyager 1 and its twin Voyager 2 are the only spacecraft ever to operate outside the heliosphere, the protective bubble of particles and magnetic fields generated by the Sun. Voyager 1 reached the interstellar boundary in 2012, while Voyager 2 (traveling slower and in a different direction than its twin) reached it in 2018.

Eclipses and the Moon - NASA Science
3 天之前 · View data source. The Moon and Solar Eclipses. Solar eclipses happen only at the new moon phase, when the Moon is between Earth and the Sun.During a solar eclipse, the Moon casts a shadow on Earth, and blocks or partially blocks our view of the Sun.
Moon Exploration - NASA Science
After a long hiatus, NASA's lunar exploration resumed in the 1990s with the U.S. robotic missions Clementine and Lunar Prospector. Results from both missions suggested that water ice might be present at the lunar poles, but a controlled impact of the Prospector spacecraft produced no observable water.
Moons: Facts - Science@NASA
Moons – also called natural satellites – come in many shapes, sizes and types. They are generally solid bodies, and few have atmospheres. Most planetary moons probably formed out the discs of gas and dust circulating around planets in the early solar system. There are hundreds of moons in our solar system – even asteroids […]

Perseverance Science Objectives - NASA Science
2024年11月18日 · Overview. Perseverance is taking the next natural step in Mars exploration. It is looking for places in Jezero Crater that were habitable in the distant past, asking whether life ever existed there, and looking for signs of ancient life.
Saturn's Rings - NASA Science
2005年8月29日 · This is an artist's concept of Saturn's rings and major icy moons. Saturn's rings make up an enormous, complex structure. From edge-to-edge, the ring system would not even fit in the distance between Earth and the Moon. The seven main rings are labeled in the order in which they were discovered. From the planet outward, they are D, C, B, A, F, G and E. The D ring is very faint and closest to ...
