Stars are always present, but during the day, the Sun’s light is so intense that it scatters in the Earth’s atmosphere, making the sky bright and obscuring the faint light from stars.
The Solar System includes the Sun, eight planets, their moons, dwarf planets, asteroids, and comets. It is structured with the Sun at the center and planets orbiting it in elliptical paths.
Meteoroids are small fragments of asteroids or comets that orbit the Sun. When they enter Earth’s atmosphere and burn up due to friction, they create a bright streak called a meteor or shooting star.
Telescopes enhance our ability to observe distant celestial objects by collecting and magnifying light. They play a crucial role in space exploration by helping scientists study stars, planets, and other astronomical phenomena.
A comet is a small solar system body composed of ice and dust, forming a glowing coma and tail when close to the Sun. Asteroids are rocky objects with no coma or tail.
The Kuiper Belt is significant as it contains many small, icy bodies and dwarf planets. It lies beyond Neptune and provides valuable information about the early solar system and the formation of planets.
Gas giants, like Jupiter and Saturn, are composed mainly of hydrogen and helium and lack solid surfaces. Terrestrial planets, such as Earth and Mars, have solid rocky surfaces and are composed of metals and silicates.
Studying exoplanets helps us understand the diversity of planetary systems, the potential for life outside Earth, and the conditions required for habitability. It also informs us about the formation and evolution of planetary systems.
A black hole is a region in space with such strong gravity that nothing, not even light, can escape. It forms when a massive star collapses under its own gravity after exhausting its nuclear fuel.
