Explanation:
Astronomers recently announced the detection of
three large planets orbiting
the star Upsilon Andromedae - the first planetary
system known to orbit a normal
star other than our Sun.
These planets were not directly photographed but found through a Doppler
technique developed to use large telescopes to
search nearby stars
for wobbling planetary signatures.
However, Upsilon And itself is visible to the unaided eye
shining in Earth's sky in
the northern constellation Andromeda at about 4th
magnitude.
This deep photographic image shows Upsilon And
along with fainter stars and "deep sky" objects including the famous
Andromeda spiral galaxy
or M31 (right), the
Triangulum galaxy or M33
(below), and the star cluster
NGC 752 (left).
About 44 light-years distant, Upsilon And is a star only a little more
massive and just slightly hotter than the Sun.
