Saturn's Rings and Moons | NASA Planetary Sciences

Explore the rings and moons of Saturn through images from the Cassini spacecraft. Saturn's rings were discovered in 1610 by Galileo Galilei, although he did not see enough detail to know what they were. In 2004, the Cassini spacecraft began capturing unprecedented images of Saturn's atmosphere and t

Planetary Geology | NASA Planetary Sciences

Meet NASA scientist Lynn Carter, who studies the geology of planetary surfaces, in this video adapted from NASA's Goddard Space Science Center. Carter describes how scientists learn about Earth by studying other planets and moons. Objects such as the Moon have older surfaces, which serve as a record

The Evolution of the Kuiper Belt | NASA Planetary Sciences

Learn about Neptune's gravitational effect on dust contained in the Kuiper belt and discover how it could help astronomers look for planets around other stars. This video from NASA explores the idea that if would-be alien astronomers were looking for planets around the Sun, they could potentially de

First Spacecraft at Neptune | NASA Planetary Sciences

Learn about the Voyager 2 mission to Neptune in this video from NASA. Voyager 2 reached Neptune in 1989, 12 years after launch, and the flyby was the first and only time a spacecraft has visited Neptune. The planet appears blue because of the methane in its atmosphere. Voyager 2 discovered at least

The Formation of Stars | NASA Planetary Sciences

Discover how the James Webb Space Telescope will help us better understand solar system formation in this video from NASA. Images from the Hubble Space Telescope show star-forming regions within the Eagle nebula: visible light images show vast clouds of gas and dust, and infrared images provide a gl

Q 11 Ring closure in carbohydrates

Hemiacetal formation by nucleophilic addition of alcohols to aldehydes is briefly explained. This is necessary to understand the ring closure in carbohydrates. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.

First Spacecraft at Uranus | NASA Planetary Sciences

Explore the planet Uranus through information gathered by the Voyager 2 spacecraft that first reached the planet in January 1986, more than eight years and 2 billion miles after its launch. As the animation explains, Uranus spins like a top tilted on its side and has a peculiar magnetic field. Rings

What Is a Dwarf Planet? | NASA Planetary Sciences

In this video from NASA, learn about the history of defining a planet, and examine how classification changes based on new knowledge. Our understanding of the solar system has evolved since the ancient Greeks, who first used the word planetes to distinguish the objects that moved against the backdro

Investigating the Moon's Interior | NASA Planetary Sciences

Discover how scientists plan to use data from the GRAIL mission and a map of the Moon's gravitational field to learn about its internal structure. By comparing data about the Moon's gravity with information about its topography, scientists can gain a better understanding of the Moon's formation and

Lunar Eclipse Essentials | NASA Planetary Sciences

Discover what happens during a lunar eclipse in this video from NASA. The orbit of the Moon around Earth causes the monthly phases of the Moon; lunar eclipses occur when the Moon passes through Earth's shadow. The video shows how the appearance of the Moon changes as it passes through Earth's penumb
