How do radio waves help astronomers?
They are simply one more way to observe distant objects and events.
When astronomers study distant galaxies they notice changes to the waves they observe describe the change to the waves they observe?
Because the universe as a whole is expanding, distant galaxies are moving away from us. As a result, electromagnetic waves emitted by those galaxies experience what is known as a red shift. Their wavelengths get longer.
What does the Astronomers use to observe the sky?
a stethoscope
How do astronomers observe the spiral of the milky way?
by eyes
How do astronomers observe the sun at different wavelengths?
Cus they is BOSS
What is a device that is used to observe distant objects?
A telescope.
Which would be easier to clean up a stream pollution or a groundwater pollution and Why?
It is always easier to cleanup something if you can get to it. * Streams (and their beds) can be worked on pretty easily. * Groundwater is pretty mysterious: flows are difficult to observe, drawdown to collect pollution depends on porosity, you don't know when the job is done
What are the different tools used in science what are the different tools used in science?
Chemists use a triple beam balance to weigh things, astronomers use telescopes to observe very distant things, biologists use microscopes to observe very small things, and there are literally thousands of other tools used by scientists in various different specialties.
How does light pollution in cities affect astronomical observations?
The additional lights from street lamps and buildings gets sent into the sky which in turn gets scattered by our atmosphere, and this hinders very faint galaxies, nebula, planets and stars to be seen.
What is an instrument used observe distant objects with the eyes?
A telescope or binoculars.
Why do astronomers move their telescopes when observing the sky?
To compensate for the motion of the Earth in order to observe a fixed object, such as a distant star. Relative to the Earth, distant objects do not move, but the Earth rotates and orbits the sun, thus all objects appear to move relative to a fixed point on the Earth. Therefore telescopes (which are fixed points) must move to compensate for this motion.
Do astronomers sleep in the daytime?
Sometimes they do, so they can observe at night. However, there's a lot more to the job than observing in "real time". Also, there are astronomers who don't need it to be dark, for example radio astronomers.
