Explanation:
They are so large, they are almost unreal.
The radio dishes of the
Very Large Array (VLA) of
radio telescopes
might appear to some as a strange combination of a dinosaur skeleton and common
satellite-TV receiving dish.
Together, the 27 dishes of the
VLA
combine high sensitivity with high resolution,
enabling a series of important astronomical discoveries, including
water ice on planet Mercury,
micro-quasars in our Galaxy,
gravitationally-induced Einstein rings around distant galaxies, and
radio counterparts to cosmologically distant
gamma-ray bursts.
Pictured above, a dish from the VLA was photographed last week near
Socorro,
New Mexico,
USA.
