The Moon’s surface features include craters, maria (dark plains), highlands, and rays. Craters are impact sites, maria are flat volcanic plains, highlands are mountainous regions, and rays are bright streaks from impacts.
Earth’s atmosphere protects life by blocking harmful solar radiation, regulating temperature, and containing oxygen for respiration. It also acts as a shield against meteoroids and space debris, preventing them from reaching the surface.
Mars is significant in space exploration due to its potential for past or present life, its similarities to Earth, and its potential for future human colonization. It is a prime target for exploration missions.
A space shuttle typically includes the orbiter, solid rocket boosters, and an external fuel tank. The orbiter houses astronauts and equipment, while the boosters and tank provide the necessary propulsion for launch.
Scientists use telescopes to collect and magnify light from distant celestial objects. Telescopes help them observe and analyze stars, galaxies, and other cosmic phenomena, providing data that enhances our understanding of the universe.
Gravity is the force that governs the movement of celestial bodies in the solar system. It keeps planets in orbit around the Sun and influences the paths of moons, comets, and asteroids.
The Sun appears large and bright because it is much closer to Earth than other stars. Its light overwhelms the faint light from distant stars during the day. At night, stars are visible as small dots due to their great ...
Stars are not the only objects in the sky. There are also planets, moons, asteroids, comets, and other celestial bodies. Many of these objects are not always visible to the naked eye and require telescopes for observation.
Yes, we can identify planets by their distinct motion and steady light. Unlike constellations, which form recognizable patterns of stars, planets move along the ecliptic path and shine steadily, making them distinguishable from the fixed stars in constellations.
