Scientista started to gather information by observing the stars and learnt from here. First they used parallax to get the distance, then the apparent brightness, but after a while they can get luminosity, size/mass, what fuel they use (eg.helium), and then from that the learnt about the starts lifetime. Hope this is helpful
What else can I help you with?
How do scientists use spectroscope to gather information about stars?
Scientists can use spectroscopes to gather information because the light from the stars that passes through has a certain color. Each element on the Periodic Table has a specific color. This way, scientist can figure out of which gases the star consists of.
Where do scientists look to gather information?
induction
When scientists gather information this information IS CALLED?
The information you are thinking about is called data.
What are the equipment used by scientists to gather information?
A paper and a pencils
What are the instrument use by the astronomer to gather information about stars?
telescope
Why do scientists publish reports in books and journals?
Because they can gather information.
What do scientists do during data collections?
Gather information during an experiment
What do scientists do during data collection?
Gather information during an experiment
How do scientist gather information?
Scientists read and communicate with each other to gather information.
How do scientists know so much about stars in distant galaxies?
Scientists use telescopes to observe and analyze light emitted by stars in distant galaxies. By studying the light's intensity, temperature, composition, and movement, scientists can gather information about the stars' age, size, distance, and other properties. This data helps scientists understand the behavior and characteristics of stars in those galaxies.
How do scientists gather information about the natural world?
Scientists gather information about the natural world through a variety of methods, including observations, experiments, field studies, data collection, and analysis. They may use tools such as microscopes, telescopes, sensors, and satellites to gather data and conduct research to understand natural phenomena and processes. Collaboration with other scientists, publication of results, and peer review are also important aspects of the scientific process.
When do scientists have to gather information without direct observations?
they use the internet they use the internet
