An astronomer need not have any particular need to observe any part of the sun's atmosphere.
To observe a lunar eclipse, you need to be in the area where the shadow of the Earth falls on the Moon. This occurs when the Earth passes between the Sun and the Moon, casting its shadow on the lunar surface.
Telescopes that collect electromagnetic radiation in shorter wavelengths, such as ultraviolet or X-rays, need to be placed in dry areas or outside the atmosphere because water vapor and other gases in the atmosphere can absorb or scatter such high-energy radiation, affecting the observations. Placing these telescopes in dry areas or above the atmosphere helps ensure that they can collect unimpeded data in these wavelengths.
Three things, really. An astronomer needs to determine the apparent brightness of a star or other object, and needs to know its distance. He would also need to have an estimate about extinction - that is, how much of the light is absorbed on its way.
Mercury would need to be at least 1.2 times more massive to hold onto an atmosphere. The lack of a substantial atmosphere on Mercury is due to its low gravity, making it unable to retain gases for an extended period. Increasing its mass would help it to have enough gravitational pull to hold onto an atmosphere.
Plants need a specific concentration of gases in the atmosphere, particularly carbon dioxide, in order to carry out photosynthesis and grow. Without the right atmospheric conditions, such as a lack of carbon dioxide, plants may struggle to survive and grow.
No atmosphere to blur the seeing. No need to wait for night, either!
The name of great Italian astronomer is Galileo. You need to read his biography. He is great as astronomer and brave soldier as well.
i dont really know but i think its 8 years of education traing to be an astronomer
Astronomer needs to take Math, Physics, science specifically (astronomy) and a little of chemistry.
One does not have to be in a specific location to be an astronomer. However, travel may be required in order to conduct studies.
You need some advance math and physic skills.
a telescope
No. The planet Mercury does not have an atmosphere.
First you need to observe the dog
You wouldn't be here / alive without atmosphere.
the receptionist needs to observe the following: if they need a cup of tea
No, but you would need one that offers that course of study. Not all do.
