Question #: 51
Topic #: 1
A team of scientists uses the Hubble Space Telescope to search for evidence of planets orbiting distant stars.
Which kind of investigation are they carrying out?

Suggested Answer: D Vote an answer

The team of scientists is using the Hubble Space Telescope to search for evidence of planets orbiting distant stars. This method involves observing celestial phenomena without manipulating any variables, making it an observational study. Unlike controlled experiments or laboratory experiments, observational studies rely on gathering data by watching natural occurrences in the environment being studied. In this case, they are observing the light from stars to infer the presence of planets. References:
