The Hubble Space Telescope is crucial for observing distant galaxies, stars, and other celestial objects. It provides high-resolution images and data that have greatly expanded our understanding of the universe.
Meteoroids are small rocky or metallic bodies in space. When they enter Earth’s atmosphere and burn up, they are called meteors. If they reach Earth’s surface, they are termed meteorites.
Earth’s rotation on its axis causes day and night. As Earth rotates, different parts face the Sun, experiencing daylight, while the opposite side remains in shadow, experiencing nighttime. This rotation cycle lasts 24 hours.
The Sun is the central star of the solar system and provides the necessary light and heat to sustain life on Earth. Its gravitational pull keeps the planets and other celestial bodies in orbit.
Space exploration is significant as it advances scientific knowledge, drives technological innovation, and provides insights into the universe’s origins. It also helps us understand Earth’s environment and find potential resources for future use.
Seasons on Earth are caused by its tilt on its axis and its orbit around the Sun. This tilt leads to varying angles of sunlight and day lengths throughout the year, creating different seasons.
Satellites play a crucial role in modern technology by providing communication, navigation, weather forecasting, and Earth observation services. They enable global telecommunications, GPS navigation, and help monitor environmental changes and natural disasters.
An eclipse occurs when one celestial body blocks light from reaching another. There are two main types: solar eclipses, where the Moon blocks the Sun, and lunar eclipses, where the Earth blocks sunlight to the Moon.
Scientists measure distances between celestial bodies using various methods, including astronomical units, light-years, and parsecs. Techniques like radar ranging, parallax measurements, and observations of star positions help determine these distances.
