What was the primary mission of the Hubble Space Telescope (HST) when it was launched in 1990?

  1. To study the formation of stars and galaxies in the early universe.

  2. To observe distant objects in the solar system, such as planets and comets.

  3. To search for signs of extraterrestrial life in nearby star systems.

  4. To monitor weather patterns and climate change on Earth.

Show answer
Correct Option: A
Explanation:

The HST was primarily designed to study the universe at large distances and to investigate the origin and evolution of galaxies and stars.

Which of the following is NOT a major scientific discovery made by the HST?

  1. The existence of black holes at the centers of galaxies.

  2. The presence of water vapor in the atmosphere of Mars.

  3. The acceleration of the universe's expansion.

  4. The age of the universe is approximately 13.8 billion years.

Show answer
Correct Option: B
Explanation:

The HST has made significant contributions to our understanding of the universe, but it was not directly involved in the discovery of water vapor on Mars.

What is the name of the camera installed on the HST that has captured iconic images of distant galaxies and nebulae?

  1. Wide Field Camera 3 (WFC3)

  2. Advanced Camera for Surveys (ACS)

  3. Near Infrared Camera and Multi-Object Spectrometer (NICMOS)

  4. Space Telescope Imaging Spectrograph (STIS)

Show answer
Correct Option: A
Explanation:

The Wide Field Camera 3 (WFC3) is a versatile instrument on the HST that has produced stunning images of galaxies, nebulae, and other celestial objects.

Which of the following is an example of a Hubble Deep Field (HDF) image?

  1. A composite image of the Andromeda Galaxy.

  2. A detailed view of the surface of Jupiter.

  3. A long-exposure photograph of the Milky Way galaxy.

  4. A deep observation of a small patch of the universe, revealing distant galaxies.

Show answer
Correct Option: D
Explanation:

Hubble Deep Field images are long-exposure observations of small regions of the sky, revealing faint and distant galaxies.

How has the HST contributed to our understanding of the Big Bang theory?

  1. By providing evidence for the existence of cosmic microwave background radiation.

  2. By measuring the age of the universe to be approximately 13.8 billion years.

  3. By observing the formation of the first stars and galaxies in the early universe.

  4. All of the above.

Show answer
Correct Option: D
Explanation:

The HST has made significant contributions to our understanding of the Big Bang theory by providing evidence for cosmic microwave background radiation, measuring the age of the universe, and observing the formation of early galaxies.

What is the name of the Hubble Space Telescope's successor, which is scheduled to launch in the 2030s?

  1. James Webb Space Telescope (JWST)

  2. Nancy Grace Roman Space Telescope (Roman)

  3. Wide Field Infrared Survey Telescope (WFIRST)

  4. Advanced Technology Large-Aperture Space Telescope (ATLAST)

Show answer
Correct Option: A
Explanation:

The James Webb Space Telescope (JWST) is the planned successor to the HST and is designed to study the universe in infrared light.

Which of the following is NOT a scientific instrument on the HST?

  1. Cosmic Origins Spectrograph (COS)

  2. Fine Guidance Sensors (FGS)
