Planets Align Over Australian Radio Telescope Array


Explanation:

Last week,
Mercury,
Venus, and the
Moon all appeared close together in Earth's sky.

This picturesque conjunction was caught on camera behind elements of
the Australia Telescope
Compact Array
(ATCA) near the town of Narrabri in rural
New South Wales.

The ATCA
consists of six
radio telescopes
in total, each one larger than a house.

Together they form one of the highest resolution
measurement devices in the world.

Impressive
planetary
conjunctions occur every few years.

Involving the brightest objects in the night sky,
this alignment was easy to spot just before sunrise.

In the picture, taken on the morning of March 6,
Mercury is the highest
of the three bright celestial beacons.
