Hubble Telescope: Observing Solar System Changes

Understanding the changes happening in our solar system requires specialized instruments capable of viewing distant celestial bodies. Let's explore the options provided:

Evaluating Observation Instruments

The question asks for the instrument used to observe changes in the solar system. The solar system includes the Sun, planets, moons, asteroids, and comets. Observing changes requires instruments with powerful magnification and the ability to capture light or other electromagnetic radiation from these distant objects.

Option 1: Hubble Telescope

The Hubble Space Telescope is a large, space-based observatory that has been in service since 1990. It orbits the Earth and captures incredibly detailed images of the cosmos. Hubble observes in ultraviolet, visible, and near-infrared light. Its advanced capabilities allow astronomers to study planets within our solar system, monitor changes like weather patterns on Mars or the rings of Saturn, and observe distant galaxies. Therefore, the Hubble telescope is suitable for observing changes in the solar system.

Option 2: Electron Telescope

An electron telescope, more commonly known as an electron microscope, uses a beam of accelerated electrons as a light source. These instruments are designed to magnify extremely small objects, such as cells, molecules, and materials, revealing details at the nanometer scale. They are not equipped or designed to view or study celestial objects like planets or stars in the solar system.

Option 3: Microscope

A standard microscope also magnifies very small objects, typically viewed in a laboratory setting. Microscopes are used for biological samples, small material structures, and other tiny items. They cannot observe objects in space.

Option 4: Both 2 and 3

Since both the electron telescope (microscope) and the standard microscope are unsuitable for observing celestial bodies and changes within the solar system, this option is incorrect.

Conclusion on Solar System Observation

Based on the capabilities of each instrument, the Hubble telescope is the appropriate choice for observing changes within the solar system. It provides the necessary power and perspective to study celestial phenomena from its vantage point in space.
