How can you use sunspots to tell that the sun is rotating on its axis?

Sunspots can be used to determine the rotation period of the Sun because they appear to move across the Sun's surface as it rotates. By tracking the motion of sunspots over time, scientists can calculate the rotation period of the Sun. This information helps confirm that the Sun is indeed rotating on its axis.


Why do sunspots move across the face of the sun?

Sunspots appear to move across the face of the sun due to the differential rotation of the sun's surface. The sun's equator rotates faster than its poles, causing sunspots to move in what appears to be an east-west motion. This differential rotation is due to the sun being a gaseous body, with different layers rotating at different speeds.


How have astronomers inferred that the sun rotates?

Astronomers have inferred that the Sun rotates by observing the motion of sunspots across its surface. This phenomenon, known as differential rotation, causes different parts of the Sun to move at different speeds, indicating that the Sun rotates. Additionally, observations of the Doppler shifts in the light emitted by different regions of the Sun also provide evidence of its rotation.


What evidence is there that the sun rotates?

Scientists study the movement of sunspots across the surface of the Sun as evidence of its rotation. The differential rotation of the Sun, where different parts of the Sun rotate at different speeds, has been observed and studied for centuries. Additionally, observations from spacecraft like the Solar Dynamics Observatory provide direct evidence of the Sun's rotation.


How can sun - pots help to determine the period of rotation of the sun?

Sunspots are darker, cooler areas on the sun's surface that rotate with the sun. By tracking the movement of sunspots across the sun's surface, astronomers can determine the sun's rotation period. This can provide valuable insight into the sun's internal structure and dynamics.

What are the two observation that Galileo made?

Galileo looked at the sun and observed dark blemishes on its surface (which are now called sunspots). From the movement of these blemishes, he was able to determine that the sun has a rotation period of about one month.


How the sun moves when the sunspots move from WEST TO EAST?

By the Sun's rotation.


Idenitify two conclusions Galileo drew from his observation of sun spot dark spot on the sun?

He looked at the sun and observed dark blemishes on its surface, which are now called sunspots. From the movement of these, he was able to determine that the sun has a rotation period of about one month.

Why would you expect there to be more uncertainty in the heliographic coordinates of sun spots near the edge of the sun?

Sunspots near the edge of the sun appear foreshortened due to perspective effects, making it difficult to accurately determine their positions. This leads to more uncertainty in their heliographic coordinates compared to sunspots at the center of the solar disk. Additionally, factors like limb darkening and varying rotation rates of the sun can further contribute to the uncertainty in determining the precise locations of sunspots near the edge.


What did scientists learn about the sun's rotation by studying the sunspots?

this is easy ... i learned it in science class..... OK......they watched the sun and discovered that new sunspots where appearing and they also notices the same ones came back every bit. ;)
