  1. Messier Catalog

  2. New General Catalog

  3. Hubble Deep Field

  4. Sloan Digital Sky Survey


Correct Option: B
Explanation:

The New General Catalog (NGC) is a catalog of deep-sky objects compiled by John Louis Emil Dreyer in 1888. It contains 7,840 entries, including galaxies, star clusters, nebulae, and other objects.

What is the primary purpose of the Messier Catalog?

  1. To identify and catalog galaxies

  2. To identify and catalog nebulae

  3. To identify and catalog star clusters

  4. To identify and catalog planets


Correct Option: B
Explanation:

The Messier Catalog is a catalog of 110 deep-sky objects compiled by Charles Messier in the 18th century. It contains a variety of objects, including nebulae, star clusters, and galaxies, but its primary purpose was to identify and catalog nebulae.

Which catalog is known for its deep images of the universe, revealing faint galaxies and other distant objects?

  1. Messier Catalog

  2. New General Catalog

  3. Hubble Deep Field

  4. Sloan Digital Sky Survey


Correct Option: C
Explanation:

The Hubble Deep Field is a series of images taken by the Hubble Space Telescope in 1995. It is known for its deep images of the universe, revealing faint galaxies and other distant objects.

What is the Sloan Digital Sky Survey (SDSS) primarily known for?

  1. Cataloging galaxies

  2. Cataloging stars

  3. Cataloging planets

  4. Cataloging nebulae


Correct Option: A
Explanation:

The Sloan Digital Sky Survey (SDSS) is a project that aims to map the universe in three dimensions. It is primarily known for its cataloging of galaxies, but it also includes data on stars, quasars, and other objects.
