Because they don't want to
Kelvin (K)
Scientists use color, size, brightness, and temperature to classify stars.
Scientists use properties such as luminosity, temperature, mass, size, and spectral characteristics to group stars. These properties help categorize stars into different classes based on their similarities and differences.
They use X-Rays from the stars being sucked into them.
They use refracting and reflecting telescopes technique is they use the parallax methods
That is one of the things scientists use to help them measure a stars distance but it isn't just based on the color.
i dont knoww
scientists use light-years to measure long distances in space. a light year, (abrviated ly) is the distance light can travel.
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.
I dont know... :P
i dont know the answer
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.
