Vulpecula is
a faint constellation in
the northern sky. Its name is Latin for
"little fox",
although it is commonly known simply as the fox.
It
is located in the middle of the Summer
Triangle (an asterism
consisting of the bright stars Deneb, Vega and Altair).
Notable features
The constellation Vulpecula as it can be
seen by the naked eye.
Stars
There are no stars brighter than 4th magnitude in
this constellation. The brightest star in Vulpecula
is α
Vulpeculae, amagnitude4.44m red
giantat a distance of 297 light-years.
The star is anoptical
binary (separation
of 413.7") that can be split using binoculars. The
star also carries the traditional name Anser, which
refers to the goose the little fox holds in its
jaws.
Pulsar
Fifteen
years after the first pulsar was discovered, the
first millisecond
pulsar, PSR
B1937+21, was also discovered in Vulpecula, only
a few degrees in the sky away from PSR B1919+21.
Planet -
Vulpecula is also home to HD
189733 b, one of the closest extrasolar planet
currently being studied by the Spitzer
Space Telescope.
with water vapour
On
12 July 2007 the Financial
Times (London)
reported that the chemical signature of water vapour
was detected in the atmosphere of this planet.
Although HD 189733b with atmospheric temperatures
rising above 1,000 °C is far from being habitable,
this finding increases the likelihood that water, an
essential component of life, would be found on a
more Earth-like planet in the future.
Deep-sky objects
Two well-known deep-sky
objects can
be found in Vulpecula. The Dumbbell
Nebula (M27),
is a large, brightplanetary
nebula which
was discovered by the French astronomer Charles
Messier in
1764 as the very first object of its kind. It can be
seen with good binoculars in
a dark sky location, appearing as a dimly glowing
disk approximately 6 arcminutes in
diameter
. A telescope
reveals its double-lobed shape, similar to that of
an hourglass.
