If they have been observing at night, yes - rather like shift workers. However most astronomers no longer observe directly but use cameras that are much more sensitive than the human eye to obtain their telescope data. This allows telescopes to be automated and the data save so that astronomers can analyse it during the day without having to visit the telescope. These astronomers work normal hours and only a few are needed to man the telescopes (a task which may also be done remotely).
