Which statement about observatories is false?

The statement that observatories must be the same temperature inside and out is incorrect. In reality, observatories often need to have controlled environments to ensure the best conditions for astronomical observations. Temperature differences between the interior of an observatory and the outdoor environment can affect the performance of telescopes, as thermal currents can distort images. Therefore, observatories are typically designed to minimize these thermal gradients rather than maintain the exact same temperature inside and outside.

In contrast, observatories are ideally located in areas with a steady atmosphere to reduce turbulence and allow for clearer images. Additionally, while astronomers may wear heavy clothing to stay warm in colder outdoor conditions, the operation of telescopes and cameras is not inherently dependent on this practice, as many operations are managed from temperature-controlled environments within the observatory. This context establishes why the other statements may be accurate reflections of observatory requirements or practices.
