What else can I help you with?
How do scientists know that there are planets circling other stars?
They have been located and identified as such by astronomical techniques.
What unit do scientists use to measure the surface temperatures of stars?
Kelvin (K)
Why do some people rely on the stars when they get lost?
The stars make excellent navigation aids, if you have the proper instruments to measure their locations.
Why do scientists measure distances to stars and observe how stars interact with one another to?
Scientists measure distances to stars to determine their exact positions in the sky and their relationships with other astronomical objects. By observing how stars interact with each other, scientists can understand the dynamics of star systems, galaxies, and the Universe as a whole, helping to unravel the mysteries of celestial phenomena.
How do astronomers know about stars if they can't travel to space?
They can be seen in telescopes and instruments can measure their light, etc.
What characteristics do scientists measure to determine the temperature and composition of stars?
Scientists measure the brightness, color, and spectral lines of stars to determine their temperature and composition. By analyzing the light emitted by stars, scientists can infer important information about their properties. The temperature of a star is usually determined by examining the peak wavelength of its emitted light, while the spectral lines reveal the elements present in the star's atmosphere.
Can the distances to nearby stars be measured by color?
That is one of the things scientists use to help them measure a stars distance but it isn't just based on the color.
Do scientists measure a stars distance from earth in meters?
No, they are much too far away, and you would have a number too large to be usable.
What measurement do scientists use for the distance between stars and Earth?
scientists use light-years to measure long distances in space. a light year, (abrviated ly) is the distance light can travel.
What are the instruments in observing stars?
Telescopes are used for observing stars.
How many stars are out of space?
We have no idea how many stars there are. At a rough guess, scientists estimate that there may be 2 trillion stars in the Milky Way galaxy, and that there may be a trillion other galaxies. There is no way to measure it in any meaningful way.
What instruments are in written in the stars?
guitar
