When the Hubble Space Telescope was launched in 1990, it allowed astronomers to see objects in space with greater accuracy and clarity. In 2003, with the launch of the Spitzer Space Telescope, astronomers saw even more objects that make up the universe. How do different types of telescopes provide different forms of data? Give examples to explain your answer.

In the paragraph below, select a word from each of the word banks to correctly complete the sentences. Word Bank 1: nearby stars • binary stars • distant stars • star clusters Word Bank 2: apparent motion • estimated distance • orbital motion • actual distance Word Bank 3: light year • big bang • deep space • parallax There are great distances between objects in space. Therefore, it is a challenge for astronomers to measure the distance between Earth and objects in other galaxies. When astronomers are trying to determine the distance from Earth to (1) _______________ and other objects, they measure the object's (2) _______________ in the sky against a distant background star. This is called (3) _______________.
