The Outlier in Western Australia
Today’s Video of the Day from the International Center for Radio Astronomy Research (ICRAR) features a time-lapse of more than 1,000 images captured at the Murchison Radio-astronomy Observatory in Western Australia.
The observatory consists of 4096 dual-polarization dipole antennas. The antennas are arranged as tiles, with each tile containing a 4×4 array of dipoles.
Since the Observatory and its antennas have no moving parts, all telescope functions such as pointing are executed by manipulating the dipole signals.
In this sequence of images, tile 107, known as “the Outlier,” is lit up by the moon.
