1. A comet is a small celestial body that consists primarily of ice, dust, and organic compounds. When it approaches the Sun, the heat causes its ice to vaporize, forming a glowing coma and a tail that points away from the Sun.

    A comet is a small celestial body that consists primarily of ice, dust, and organic compounds. When it approaches the Sun, the heat causes its ice to vaporize, forming a glowing coma and a tail that points away from the Sun. In contrast, asteroids are made mostly of rock and metal and do not develop tails. They remain in the asteroid belt between Mars and Jupiter.

  2. The Moon’s phases are caused by its orbit around Earth and the varying angles of sunlight that illuminate its surface. As the Moon moves in its orbit, different portions of the illuminated half are visible from Earth. This results in phases such as new moon, crescent, first quarter, gibbous, and fulRead more

    The Moon’s phases are caused by its orbit around Earth and the varying angles of sunlight that illuminate its surface. As the Moon moves in its orbit, different portions of the illuminated half are visible from Earth. This results in phases such as new moon, crescent, first quarter, gibbous, and full moon. The cycle repeats approximately every 29.5 days, known as a lunar month.

    The Milky Way galaxy is significant because it is the galaxy that contains our solar system. It is a barred spiral galaxy, characterized by its spiral arms and central bar structure. With an estimated 100 to 400 billion stars, including our Sun, the Milky Way is a fundamental part of our cosmic neighborhood. It also serves as a reference for studying other galaxies in the universe.

    Scientists measure distances between celestial bodies using units like astronomical units (AU), light-years, and parsecs. Techniques include radar ranging for nearby objects, parallax measurements that use the Earth’s orbit to gauge distance, and observing the positions of stars over time to calculate distance through triangulation. These methods help astronomers map the vast distances in space and understand the scale of the universe.

  5. An eclipse happens when one celestial body temporarily blocks the light from another. There are two main types of eclipses: solar and lunar. In a solar eclipse, the Moon passes between Earth and the Sun, casting a shadow on Earth and blocking sunlight. In a lunar eclipse, Earth comes between the SunRead more

    An eclipse happens when one celestial body temporarily blocks the light from another. There are two main types of eclipses: solar and lunar. In a solar eclipse, the Moon passes between Earth and the Sun, casting a shadow on Earth and blocking sunlight. In a lunar eclipse, Earth comes between the Sun and the Moon, casting a shadow on the Moon and causing it to darken.
