What else can I help you with?
If a space traveler went into space and looked at earth what would he see?
The space traveler would see a bright blue planet with white clouds swirling around it. They would see continents and oceans, and depending on the time of day, they might see city lights or natural phenomena like auroras. Earth would appear as a beautiful and fragile oasis in the vast darkness of space.
Are stars visible from space?
Yes. In fact, you can see more from space, as there is no atmosphere to look through and you can see much more of the sky. You also don't have day and night, like you do when you are on the surface of a planet. So you can see stars at any time.
Why do you have rockets?
Rockets are used for space exploration, satellite launches, scientific research, and commercial purposes like delivering goods and services to space. They are the most efficient way to reach and maneuver in space due to the high speeds they can achieve.

What do Doppler shift observations of a spectroscopic binary star enable astronomers to calculate?
They let us see the speed of the stars around the common center of mass. More precisely, the Doppler shift will only detect the component of this speed in our direction - that is, towards us, or away from us.
When a wave source is moving toward or away from an object the wavelength changes a phenomenon known as the?
The Doppler Effect See related link
How does Doppler effect used in medicine?
When an object moves in relation of the observer, it emits the the compressed sound waves, as it comes closer to observer and vise verse. This effect is called as Doppler effect. So you can precisely study the movement of blood across the different valves and chambers of the heart. You can give different colors to give the color Doppler effect for better understanding the flow of blood. Like wise you can see the blood flow across the deep veins of the legs and other blood vessels.
Why train makes sound when moves?
The Doppler Effect , if I understood your question correctly . See link for further information .
What is droppler effect?
The Doppler effect is the mix of red shift and blue shift. For example when your walking down the street and a car drives up from behind you and you don't see it but hear it your hearing the blue shift of the Doppler effect. also same scenario but the car has passed and driving away in front of you then your hearing the red shift of the Doppler effect. hope that helps I'm in 8th grade might wanna check but I'm pretty sure that's right well that's what we learned today anyway...:)
How can you measure how fast the universe is expanding?
By using some method other than the Doppler effect to calculate the distance of a distant galaxy, and using the Doppler effect to see how fast it moves away from us. A galaxy's distance and how fast it moves away from us are roughly proportional.
What creates a red shift?
On short distances (ie. within a few million lightyears), the redshift we see is the direct result of the Doppler effect. The Doppler effect causes light from receding sources to be less energetic, and thus red-shifted. On distances exceeding that, redshift can be attributed to the metric expansion of the universe. In cosmological redshift, the shifting of frequencies is basically caused by the stretching of space the light is passing through, and the stretching of the light wave with it.
As you drive down the road you see and hear an approaching ambulance How is the frequency you hear different from that being produced by the ambulance?
The wavelengths of the sound are compressed, making them shorter, and thus the frequency (and the pitch) higher. So the person in the oncoming car hears the siren operating at a higher pitch than the ambulance driver hears the same siren. This phenomenon is known as the Doppler effect.
What does it look like when you reach the end of the universe?
There probably is no end to the Universe. A finite end is based on the cosmological red shift being a Doppler effect on photon frequency. However there is no independent verification of this. I suspect that the red shift is actually from an interaction with masses passed in space. To see a discussion of this access http://www.geocities.com/isoptera.geo/redaw.html
What is Doppler?
Doppler |ˈdäplər|Doppler, Johann Christian (1803-53), Austrian physicist. In 1842, he discovered what is now known as the Doppler effect. Doppler effectnoun Physicsan increase (or decrease) in the frequency of sound, light, or other waves as the source and observer move toward (or away from) each other. The effect causes the sudden change in pitch noticeable in a passing siren, as well as the redshift seen by astronomers.
How meteorologists use Doppler effect in weather forecasts?
Meteorologists use the Doppler effect in weather forecasts by analyzing how the frequency of radar waves is altered when they interact with precipitation particles. By measuring the change in frequency, meteorologists can determine the speed and direction of winds associated with storms, as well as the intensity and movement of precipitation. This information helps in predicting the development and movement of weather systems with greater accuracy.
What scientific term would be used to explain how an ambulance siren sounds different as it approaches you then when it moves away?
The Doppler effect. It defines the relative change in frequency and wavelength of any waveform perceived by the observer when the observer is at a distance from the source and not with it. Check out a flash animation to understand this effect better.
What does space needle look like?
like a space needle haha Google that and you will see it
