1. Microscope
2. Telescope
3. Special cameras able to detect certain frequencies of electromagnetic radiation, that the human eye does not perceive (infrared, ultra-violet, gamma rays, x-rays, etc...)
An observation using instruments involves collecting data or information about a phenomenon through the use of technological tools such as telescopes, microscopes, sensors, or satellites. These instruments help scientists to gather precise measurements and observations that may not be possible with just the human eye.
So that we can learn more about what is around us and someday find a planet that can sustain human life and send people there.
1) Because they HAVE different characteristics,2) Because they are at different distances, 3) Stars may also look different because of dust and gas, between us and the stars, that absorbs part of the starlight.
The telescope allowed people to see farther into the universe, leading to new discoveries about space and the solar system. The microscope enabled scientists to observe and understand the world of microorganisms, revolutionizing our understanding of biology and medicine. Both instruments expanded human knowledge by revealing the vastness of the cosmos and the complexity of the microscopic world.
I think "scientist" is an awfully strong word to use for "prehistoric human who wasn't actually blind." Crystals are pretty common and not exactly hard to spot, so it's only slightly more reasonable than asking "who was the first astronomer to discover the Moon?"
life scientist studies about living things for example bird,plant and human being
While one can not truly just jump into the past and see previous human activity, Archaeologists can study the remains left over. There are also other scientist that can observe tracks and enviornment to determine human activity, but the name I can not recall at the moment.
Its not like that there is no such things like that the human does not know this EVEN THE SCIENTIST does not know this

A behavioral scientist studies human behavior, often in relation to society and environment. They use scientific methods to understand and predict human actions, motivations, and decision-making processes. Behavioral scientists work across various disciplines such as psychology, sociology, and economics.
Antonie van Leeuwenhoek is the scientist known for using single-lens microscopes to observe bacteria, human blood cells, and other microorganisms. He was a Dutch tradesman and scientist who made significant contributions to the field of microbiology in the 17th century.
No human being lives in Antarctica, except for scientist studying things there, but they too do not live there.
a scientist who studied the human body
Knowledge + Human = Scientist
A scientist
An anthropologist is a scientist who studies and compares the customs, beliefs, and ways of life of different groups of people. They often conduct fieldwork to observe and understand the cultural practices of various societies. By examining human behavior and social structures, anthropologists seek to gain insight into the diversity of human experiences.
Physiologically speaking, the Anatomist studies Anatomy.
