Q:
Do the Chandra photos only come in one or two a month, or do you take a lot of photos to get one?
A:
In a typical month, Chandra will
take observations of approximately 35 different objects (we call them
targets). Not all of them are complete observations, some of them are
observed more than one time over a few months or more. Many
observations do not yield beautiful images, they may be point sources
or spectra of important objects. In order for us to post an image on
the website, the data must be worked on for a long time by the
scientists and then accepted for publication in a scientific journal.
So the answer to your question is yes, Chandra makes many more
observations than the one or two images posted to the website each
month. More information on the process may be found here:
