Do you remember the Australian Compact Array Telescope that we mentioned near Narrabri? We said we'd point out the MOPRA telescope, that works with that array in Narrabri to make it a super-powerful telescope.
The MOPRA telescope can be rather hard to see, particularly if the dish is turned on its side. Look back over your right shoulder. Tucked up in the mountain as the road sweeps around the corner. You'll need to keep your eyes peeled for a big white telescope dish.
The 22-metre Mopra Radio Telescope is operated by CSIRO and is named because it sits right next to Mopra Rock - the mountain top overlooking the telescope that looks like a man's bald head.
It is not part of the solar system drive, or open to the public, but certainly something of astronomical interest along the way!
We're only a few minutes from Jupiter.
