Two types of antennae

We're home briefly before our trip to Japan.  We got close-up views of two very different types of antennae right here in our back yard.

This guy found his way into our kitchen.  In a rare feat of bravery, Crazy Girl calmly invited me to come and remove him.  He is a Green Stink Bug.  My amateur etymologist's eye didn't detect any similarities to the shiny black monsters that I grew up calling stink bugs.  Check out the giant antennae on him.

Bugs in the house!
Here is a different type... a radio telescope that is part of the CARMA array of telescopes which spans across the Southwest and Hawaii.  When signals from these hundreds of telescopes are combined, it creates the effect of one giant telescope that is thousands of miles across.  This one is huge - at least five stories high.  Note the staircase and door at its base, and other telescopes in the background.  These are about 3 miles from our house just on the other side of the Owens River.
