Explanation:

Question 1

The Great Observatories Program by NASA uses 4 different types of telescopes (specifically space telescopes) to collect information about the universe. These telescopes are designed to detect different parts of the electromagnetic spectrum to observe various celestial objects.

• The Hubble Space Telescope is designed to detect visible light, ultraviolet light, and some infrared light.
• It helps astronomers get a better view of galaxies (like the Andromeda Galaxy), stars, and nebulae (like the Orion Nebula).

• The Chandra X - ray Observatory is built to detect X - ray radiation from celestial sources.
• It is very useful for observing black holes, neutron stars, and hot gas in galaxy clusters.

Answer:

telescopes (or space telescopes)

Question 2

The four parts of NASA's Great Observatories Program are the Hubble Space Telescope, Chandra X - ray Observatory, Spitzer Space Telescope (now retired, but was part of the program), and Compton Gamma Ray Observatory (also retired). Here is the breakdown for each:
