Key Differences
A telescope is an optical instrument designed primarily for the observation of distant objects like stars, planets, and galaxies. It gathers and magnifies light to present a clearer image of these celestial entities. On the flip side, a microscope is devised for magnifying very small objects or details, usually not visible to the naked eye, such as bacteria, cells, or the intricate patterns on a surface.
Both telescope and microscope function on the principle of magnification, but they serve vastly different fields. While telescopes are instrumental in the realm of astronomy and the study of the universe, microscopes are pivotal in biology, medicine, and materials science. Their designs cater to their respective purposes: telescopes often have larger apertures to collect more light from distant stars, while microscopes focus on illuminating and enlarging minuscule subjects.
One primary distinction between a telescope and a microscope lies in the nature of the observed object. The former looks outwards into the vast expanse of space, enabling us to understand the universe's workings. In contrast, the microscope looks inwards, delving deep into the minute details of matter, revealing the intricate complexities of life and materials.
Another point of difference is the lens system. A telescope primarily uses two lenses (objective and eyepiece) to bring distant objects into focus, whereas a microscope often employs multiple lenses to achieve the high magnification necessary for viewing tiny specimens.

Microscope
A microscope (from the Ancient Greek: μικρός, mikrós, "small" and σκοπεῖν, skopeîn, "to look" or "see") is a laboratory instrument used to examine objects that are too small to be seen by the naked eye. Microscopy is the science of investigating small objects and structures using a microscope.
Telescope
A telescope is an optical instrument using lenses, curved mirrors, or a combination of both to observe distant objects, or various devices used to observe distant objects by their emission, absorption, or reflection of electromagnetic radiation. The first known practical telescopes were refracting telescopes invented in the Netherlands at the beginning of the 17th century, by using glass lenses.
Microscope

Common Curiosities
Why do microscopes have multiple lenses?
Multiple lenses in microscopes provide greater magnification and detail.
Can I use a microscope to see stars?
No, microscopes are for tiny, close objects, not distant celestial bodies.
Are electron microscopes a type of telescope?
No, electron microscopes are a type of microscope that uses electrons, not light.
Can telescopes be used to view microscopic objects?
No, telescopes are designed for distant objects, not microscopic ones.
Why are some telescopes placed in space?
Space telescopes avoid Earth's atmosphere, providing clearer images.
