Read this excerpt from NASA's explanation of black holes. When you encounter a word you don't know, look for context clues that might help you define the word.
Scientists can't directly observe black holes with telescopes that detect X-rays, light, or other forms of electromagnetic radiation. We can, however, infer the presence of black holes and study them by detecting their effect on other matter nearby. If a black hole passes through a cloud of interstellar matter, for example, it will draw matter inward in a process known as accretion. A similar process can occur if a normal star passes close to a black hole. In this case, the black hole can tear the star apart as it pulls it toward itself. As the attracted matter accelerates and heats up, it emits X-rays that radiate into space. Recent discoveries offer some tantalizing evidence that black holes have a dramatic influence on the neighborhoods around them--emitting powerful gamma ray bursts, devouring nearby stars, and spurring the growth of new stars in some areas while stalling it in others.
Considering all of the context clues around the word telescopes, what can you assume that telescopes are able to do?
see black holes clearly
detect X-rays, light, and electromagnetic radiation
see gamma ray bursts
predict when a new black hole has formed
