The instrument scientists use to observe the planets is a high powered telescope.
I think they use a telescope
a telescope
Tools enable scientists to make more accurate observations, and to observe things that they otherwise could not observe. For example, microscopes allow scientists to observe bacteria, which otherwise are too small to see.
to observe a 1000year process in just one day
to observe a 1000year process in just one day
observing pictures of the terrain; inferring what the images are; measuring the distance between features (such as rocks); interpreting meteorological information to try to understand the climate on Saturn
Scientists have to measure things accurately or else science would be pointless,
telescope
they use satellites.
teleschope and a engredeance
Based on things, they use everything. Scientists observe then say what they think.

it depends on the size of the To_observe_a_small_living_organism_a_scientist_might_use_a. If it is microscopic, then scientists might have to observe it using it using a microscope. If it can actually be seen, then scientists mught actually take a sample of it back to the labratory to observe physically

Microscope. A scientist might use a microscope. Well actually, it depends on the size of the animal. If it is microscopic, then scientists might have to observe it using it using a microscope. If it can actually be seen, then scientists mught actually take a sample of it back to the labratory to observe physically.
The scientist should use a light microscope.
