The Sky Of the Month. SOUTHERN HEMISPHERE. June 2011.
Look to the northeast and you'll be looking at a place
located between the constellations of Ophiuchus and Hercules
which is now the Voyager I
the spacecraft has traveled more distance
Now it´s located at the outer limits of the heliopause
a solar system area isolated from the influence of the sun
Its nuclear fuel will be exhausted in 2020
and in its eternal journey to the stars
will be a silent witness
presence of humanity in the Universe
Constellations and deep sky objects
In Greek mythology Ophiuchus, also called Escolapio
was the physician of the Argonauts
Zeus killed him
fearing he had the skills to revive people
and placed it in the sky, near the Snake
as it represented the renewal of life
Rasalhague represents the head of the Serpent Bearer
is the brightest star
visible in the early hours of the night on the eastern horizon
This constellation is rich in globular clusters
highlighting its beauty M9, M14
M107, M10, M12 and M62
the last three visible through binoculars
We approached the nearness of the second brightest star in Ophiuchus
the Sabik star
In the year 1604 a supernova exploded in this region of the sky
Because to its proximity you could see with the naked eye
and was studied by astronomer Johannes Kepler
hence the name of it
Today is a beautiful remaining invisible in the optical
but the Chandra X-ray space telescope
have shown this wonderful picture
The emission nebula Sharpless 27 is not observable as low brightness
but the use of filters and digital processing images
shows the breadth and beauty
At the foot of the Serpent Bearer
and 400 light years away from us
is the binary star Rho Ophiuchi
surrounded by a blue cloud of gas and dust
is the reflection nebula IC 4604
which takes its color from light that iluminate blue and young stars
In fact, this nest of stars
is more than 100 light years away from Rho Ophiuchi
Ophiuchus is the bearer of the constellation Serpens
which is divided in two, Serpens Caput and Serpens Cauda
the head and tail of the snake
Highlight in the tail of the snake M16, The Eagle Nebula
is an open cluster of more than 400 stars
associated with an emission nebula
within which are the so-called "Pillars of Creation"
are actually huge columns
of dust and molecular gas that condense and create stars
At midnight and below Ophiuchus
is located the constellation of Hercules
whose central body is a trapezoid
Very easy to find among the stars Eta and Zeta Hercules
is the third brightest globular cluster in the sky
M13, visible to the naked eye in dark skies
Your first sighting of M13 by telescope is a feeling of awe and shaking
Next to this sphere with points expand a characteristic "spider legs"
and it´s even more fascinating to know that we are seeing
more than 500,000 stars suspended in space-time
as they were 25.000 years ago
when Neanderthals still existed on Earth
Over southern horizon, almost in the zenith lies Scorpio
in an everlasting chase, Orion flee hiding by the west
Scorpius contains many deep sky objects
visible to the naked eye or binoculars
M4, the closest globular cluster
near is M80, another globular cluster
open cluster M6 or Butterfly cluster is visible to the naked eye
the bright yellowish star of the picture is a yellow supergiant star
M7, Ptolemy's cluster is also visible without magnification
NGC 6302, the Bug Nebula
has a bipolar structure observing with telescopes
The Hubble Space Telescope image
shows the nebula in its fullness
Ara, the shrine, is a constellation in which there is a star
(Mu Arae) same to the Sun
that we can see with the naked eye
and where we now know that at least four planets orbit
and possibly one of those rocky
Nearby is the globular cluster NGC 6397
in visual limit of the human eye
In the Ara skies is the zoo star Westerlund 1
a very young star cluster containing a variety of known types of stars
from yellow supergiants and hypergiants to blue variable stars
half a million stars contained in an incredible space only 6 light years
If the Sun were located in the center of the cluster
the sky would be full of stars
and many of them would be brighter than the full Moon ...
Very near Ara, an asterism sketched by six stars
with a semi-circle shape represents the constellation Corona Australis
Near the star Epsilon is located a beautiful grouping of three nebulae
next to its observed with binoculars the globular cluster NGC 6723
that belongs to the constellation of Sagittarius
We emphasize the nebula NGC 6729
a nursery of stars very close to the sun
the stars of inner can not be seen directly, but yes its influence
as the material ejected by these newly born
travels at speeds of up to a million kilometer per hour
colliding with the surrounding gas
creating shock waves that make the gas glow
and get these incredible forms
In the early days of June will see the cluster Omega Centauri
from zones of the northern hemisphere below 40 degrees latitude
This month Looking Southern sky
will be observed The Crux constellation from Mexico
ASTRONOMICAL EVENTS
On June 21 occurs the shortest day and longest night of the year
in the southern hemisphere, announcing the beginning of winter
The combination of translational motion of the Earth around the Sun
and the tilt which keeps the planet's rotation axis
with the plane of Earth's orbit
cause the projection of the Sun on the Earth's surface
varies throughout the year
being solstice in June when the lowest is in the South Hemisphere
The sun, like a pendulum
moves to the sunrise over the horizon and
shortly before arriving at the June Solstice
it seems to stop in the sky
hence the name "Solstice", "Quiet Sun" in Latin
The Sun, which has been appearing increasingly in the north
stops and appears in the same place for a few days
then starting their shift to the South to meet the December solstice
its maximum distance from the eastern horizon
On June 15 there will be a total lunar eclipse
Visible at sunset in South America and dawn in Australia
The Earth will be between the moon and sun
so if you were in a Lunar base, that day would see a solar eclipse
On June 1 there will be a partial eclipse of Sun
but only seen in very high latitudes of the Northern Hemisphere
On June 10, Saturn will be easily located
facing North and below the crescent moon
but must be distinguished from Porrima
the beta star in the constellation Virgo that is very close to him
At dawn, Jupiter, Mars and Venus will gradually spreading in the sky
following their unperturbed orbital paths around the Sun
The New Moon is June 1
and day 15 at moonrise the full moon
will be eclipsed by the shadow of the Earth
The meteor shower of June´s Bootids
is associated with the comet 7P/Pons-Winnecke
Fall between June 22 and July 2 and is expected variable maximum to the 27th
Have the lowest speed of inclusion on the Earth's atmosphere
just 18 km/s
Its radiant is in the constellation Bootes
Gaze at the stillness of the sky over your head
and you will perceive the movement of the earth under your feet ...
