    $\begingroup$ Time-domain astronomy is a very broad and interesting field. Things getting in the way (Sun, Moon, Earth) are a problem for understanding what's happening. en.wikipedia.org/wiki/Time-domain_astronomy $\endgroup$

    $\begingroup$ "Because in six months we're going to be there ourselves." In that case, when we get there we could leave a space telescope there and continue on our way. . $\endgroup$

    $\begingroup$ "Another half year more or less isn't likely to make much difference in our model of the universe." - Sure, but when a neutrino burst is detected telescopes everywhere spring into action to try and locate where it came from. Same for when a gravitational wave is detected. Talking of which scopes at L4 and L5 potentially provide part of a very large base line GW detector, many orders of magnitude larger than LIGO. Also the larger baseline improves parallax measurements considerably and the comms links will be useful for future space exploration. $\endgroup$

    $\begingroup$ "In astronomy not much changes over that time frame." ~~ Everybody gangsta until we miss a supernova because the Sun was in the way. $\endgroup$
