Which telescope design is credited with pioneering modern astronomy and enabling the discovery of Uranus?

  1. Refracting Telescope

  2. Reflecting Telescope

  3. Catadioptric Telescope

  4. Radio Telescope


Correct Option: B
Explanation:

The reflecting telescope, with its large light-gathering capabilities, revolutionized astronomy. William Herschel's reflecting telescope led to the discovery of Uranus in 1781.

What is the fundamental difference between a refracting telescope and a reflecting telescope?

  1. Refracting telescopes use lenses, while reflecting telescopes use mirrors.

  2. Refracting telescopes are smaller, while reflecting telescopes are larger.

  3. Refracting telescopes are used for observing planets, while reflecting telescopes are used for observing stars.

  4. Refracting telescopes are more expensive, while reflecting telescopes are more affordable.


Correct Option: A
Explanation:

The primary distinction lies in the optical elements used. Refracting telescopes employ lenses to converge light, while reflecting telescopes utilize mirrors to reflect and focus light.

Which telescope type is renowned for its ability to detect and study radio waves emitted by celestial objects?

  1. Optical Telescope

  2. Infrared Telescope

  3. X-ray Telescope

  4. Radio Telescope


Correct Option: D
Explanation:

Radio telescopes are specifically designed to capture and analyze radio waves, enabling astronomers to explore the universe in a different wavelength range.

The Hubble Space Telescope, launched in 1990, revolutionized astronomy by providing:

  1. High-resolution images of distant galaxies

  2. Detailed observations of planets in our solar system

  3. Precise measurements of the age of the universe

  4. Discovery of new exoplanets orbiting distant stars


Correct Option: A
Explanation:

The Hubble Space Telescope's primary contribution lies in its ability to capture stunning high-resolution images of distant galaxies, nebulae, and other celestial objects.

What is the primary advantage of using adaptive optics in telescopes?

  1. Correcting for atmospheric distortions

  2. Enhancing the telescope's magnification

  3. Increasing the telescope's light-gathering power

  4. Reducing the telescope's size and weight


Correct Option: A
Explanation:

Adaptive optics technology is employed to compensate for distortions caused by Earth's atmosphere, resulting in sharper and clearer images.

The Very Large Telescope (VLT) in Chile consists of:

  1. Four 8.2-meter telescopes

  2. Two 10-meter telescopes

  3. Three 12-meter telescopes

  4. Six 6-meter telescopes


Correct Option: A
Explanation:

The VLT comprises an array of four individual 8.2-meter telescopes that can be combined to form a single giant telescope.

Which telescope is known for its groundbreaking observations of the cosmic microwave background radiation?

  1. Chandra X-ray Observatory

  2. Spitzer Space Telescope

  3. Wilkinson Microwave Anisotropy Probe (WMAP)

  4. James Webb Space Telescope


Correct Option: C
Explanation:

The Wilkinson Microwave Anisotropy Probe (WMAP) was specifically designed to study the cosmic microwave background radiation, providing valuable insights into the early universe.

What is the primary purpose of the Atacama Large Millimeter Array (ALMA) in Chile?

  1. Observing radio waves from distant galaxies

  2. Detecting exoplanets orbiting other stars

  3. Studying the formation and evolution of stars

  4. Measuring the expansion rate of the universe


Correct Option: C
Explanation:

ALMA is primarily used to observe millimeter-wavelength radiation, enabling astronomers to study the formation and evolution of stars and galaxies.

The James Webb Space Telescope (JWST) is equipped with:

  1. Visible light detectors

  2. Infrared detectors

  3. X-ray detectors

  4. Ultraviolet detectors


Correct Option: B
Explanation:

The JWST is designed to detect infrared light, allowing it to study objects that are obscured by dust and gas in visible light.

Which telescope is renowned for its discovery of the first exoplanet orbiting a Sun-like star?

  1. Kepler Space Telescope

  2. Hubble Space Telescope

  3. Spitzer Space Telescope

  4. Chandra X-ray Observatory


Correct Option: A
Explanation:

The Kepler Space Telescope was specifically designed to search for exoplanets, and it successfully discovered the first exoplanet orbiting a Sun-like star in 2009.

What is the primary function of an interferometer in astronomy?

  1. Combining the light from multiple telescopes to achieve higher resolution

  2. Measuring the distance to stars using parallax

  3. Detecting faint objects that are too dim for a single telescope

  4. Correcting for atmospheric distortions


Correct Option: A
Explanation:

Interferometers combine the light from multiple telescopes to create a single image with much higher resolution than any of the individual telescopes could achieve on their own.

The Event Horizon Telescope (EHT) is a collaboration of telescopes that aims to:

  1. Study the formation and evolution of galaxies

  2. Detect and characterize exoplanets

  3. Image the supermassive black hole at the center of our galaxy

  4. Measure the cosmic microwave background radiation


Correct Option: C
Explanation:

The EHT is a network of radio telescopes that work together to create images of the supermassive black hole at the center of our galaxy, Sagittarius A*.

Which telescope is designed to study the polarization of light from distant galaxies?

  1. Subaru Telescope

  2. Gemini Observatory

  3. Gran Telescopio Canarias

  4. Very Large Telescope


Correct Option: A
Explanation:
