Mars South Pole Is Mostly Water!


Image: NASA/MOLA Science Team

This image of Mars' south polar region shows the ice cap (in white) within the smooth polar layered deposits that overlie the cratered southern highlands.

 

MIT Discovers Martian Water

MIT’s team of planetary scientists used topographical and gravitational data gathered by three Mars orbiters to find the volume and mass of the ice cap. They were then able to calculate density and make their determination, which appeared in the September 21, 2007 issue of Science.

The new results show that water, not carbon dioxide, is the predominant frozen liquid found in the southern polar region of Mars … water ice is the dominant constituent beneath a thin dust veneer … Maria Zuber, MIT professor of geophysics

The southern Martian polar region is the largest body of frozen water on the planet and the largest, outside of Earth, in the inner solar system, which includes Mars, Earth, Venus and Mercury. Full MIT News Article

Mars and Earth are hurtling toward each other! By September 25 Mars is as close to Earth as our Sun, 93 million miles or one AU. By December 18 Mars is at its closest, a distance of only 55 million miles. The Red Planet reaches opposition and peak brightness December 24. The best views of Mars occur from October 2007-February 2008.

The Red Planet rises in the northeast at 11:15pm in the beginning of Libra, by its end at 10:30pm and moves toward the south as the morning progresses. By sunrise it lies near overhead. Mars is positioned among the bright and beautiful winter stars, near the feet of the Gemini Twins, as it moves toward a direct alignment with red Betelgeuse to the south. Star Map Look Up! Watch Mars grow redder, brighter and bigger as its distance from Earth decreases over the next few months.

Telescoping Mars

If you view Mars around midnight in early October, the hemisphere facing Earth will include Syrtis Major, the planet's darkest and most recognizable feature [Image]. Mars rotates once every 24.5 hours. As a result, martian features seen at the same time each night appear to rotate backward out of sight. Astronomy Magazine 10/07

Have You Seen the Shape Shifting Red Triad Yet?

Look for the red triangle formed by Mars, Aldebaran in Taurus southwest of the planet, and Betelgeuse in Orion southeast of the planet; compare the red color, brightness and size of each. October 1-3 a waning Moon transits the red triad, first aligning with Aldebaran, then Mars and finally Betelgeuse. Click Moon Dances for a map and reflections.

Note: As Mars changes its position in the sky, this triangle shifts its shape!

 

Reflections ~ Red Triad ~ Mars Approach

Energies of struggle and sacrifice (Mars), love and service (Betelgeuse) and illumination and elightenment (Aldebaran) circulate through and emanate from the Red Triad, which acts as a generator for the creation of new world. Look Up! Take part in the divine transition.

Choose your battles well during this approach. The spiritual warrior knows that apparent outer enemies are really a reflection of inner demons. Slay the demons within by raising them into the light, rather than lashing out at others. Find the common ground and the unity within the diversity. Create right relationship.

Blazing Venus Is a Stunning Predawn Dance Partner …
Pairing-Up and Nestling with Regulus, Saturn, the Crescent Moon!
View During Libra – 4:30am-Sunrise

Image: Magellan Project / JPL / NASA

Image Description

Image: Very Large Telescope (VLT)

Image Description

Venus and Saturn are in a striking predawn encounter along with Regulus, the brightest star in Leo the Lion, the Lion’s blue-white heart star. Venus, achieving greatest brilliancy at magnitude -4.8 September 23, is "knock your socks off" stunning as it first approaches Regulus, then Saturn from the west and finally passes both of them to the east.

Mark Your Calendar!

October 6, Saturday morning, a waning crescent Moon lies above the Venus, Regulus and Saturn trio; October 7, predawn Sunday, the waning Crescent Moon joins the trio near Saturn. Star Map October 8, Monday, a sliver of a Moon lies below the trio.October 9, Tuesday, Venus passes 3 degrees* south of Regulus.

Moon Dances October 6-8
Map and Reflections

October 13 and 14, Saturday and Sunday morning, Venus lies closest to Saturn. 10/13 Predawn Map/Text These two planets are in exact conjunction October 13 at 9:28pm PDT; 04:28 UT 10/14. October 15 Venus passes 3 degrees* south of Saturn. 10/15 4:30am Map In the beginning of Libra Venus rises at 3:45am followed by Saturn at 4:25am. By Libra's end Saturn rises at 3:15am followed by Venus at 3:30am.

Reflections ~ Venus, Saturn, Regulus, Leo the Lion

The potent dance and pairing of Venus with Regulus and Saturn occur in the constellation Leo the Lion.

Leo's highest expression is the fully integrated personality who stands out from the "herd" and is ignited by the fire of Divine Will. Venus the Goddess of Love together with Saturn the Gatekeeper bring a sobering, evolutionary quality of love to relationships. It’s as if they are assisting Regulus the Lion-Hearted Lawgiver who acts as a regulator for the evolutionary energies of Sirius and the Christ consciousness.

Note: There have been 3 recent conjunctions of Venus and Saturn in the constellation Leo the Lion near Regulus: July 1 above the western horizon, August 13 in the Sun's glowing embrace, and now October 13/14 above the eastern horizon.

Humanity is being required to rise up with a wise love that sees beyond duality, a love that encompasses the whole and aligns with the Law of the Soul. This love when mastered can resolve conflicts and establish harmony. It leads to synthesis.

Mercury gives a poor performance for Northern Hemisphere observers as it hugs the southwestern horizon after sunset. September 29 the planet reaches greatest elongation. Early October it sinks toward the horizon becoming difficult to see in the sunset glow. October 12, right after sunset-7:00pm, use binoculars to spot a difficult to see thin Crescent Moon just below elusive Mercury low in the west-southwest. October 23 the planet is embraced by the Sun in inferior conjunction. Late October Mercury reappears in the morning sky.

Mercury retrograde (10/12-10/31) brings with it a shift or change in direction. Allow the new incoming energies to break up the old patterns. Surrender and maintain.

Voyager 1, Jupiter’s Galilean Family, Faint Jupiter Ring

Jupiter and its four planet-size moons, called the Galilean satellites, were photographed early March 1979 by Voyager 1 and assembled into the above collage, which was released June 22, 1979. The moons are not to scale but are in their relative positions. Reddish Io (upper left) is nearest Jupiter; then Europa (center); Ganymede and finally Callisto (lower right) the farthest from Jupiter. Voyager 1 returned spectacular images of their terrain, including an erupting volcano on Io, the first seen anywhere other than on Earth. These photographs opened up a completely new world for planetary scientists.

Not visible in the above montage is Jupiter's faint ring of particles, seen for the first time by Voyager 1. View this ring’s location around the planet. This discovery led eager scientists to learn more about Jupiter’s rings.

 

Voyager 1 ~ 30 Years Old!

A mission that was supposed to last just five years is celebrating its 30th anniversary! Launched September 5, 1977, Voyager 1 is now at the outer edge of our solar system and continues to this day to beam back new information! It is the most distant human-made object in the cosmos.

Voyager 1 ~ Overview and History

 

Jupiter, located above and to the east of Antares, the heart star of the cosmic Scorpion, is sinking toward the southwestern horizon giving us roughly 2 1/2 hours viewing time. This is your last good opportunity to view the planet's 4 Galilean moons before they disappear into the western twilight. You need only use binoculars, if your sky is dark enough! Jupiter sets in the beginning of Libra around 10:30pm and by its end at 9:00pm.

Jupiter’s a Fun Planet to Watch

Check out the steady glow of Jupiter and the twinkling gleam of Antares. Can you detect their color differences? Jupiter is reflecting the yellow color of sunlight, while Antares is making its own light, which burns a cooler red. Here’s some fun food for thought!

Look for the waxing Crescent Moon in the vicinity of Jupiter and Antares, October 14-17. Make sure to look soon after sunset or you’ll miss the heavenly view! Click Moon Dances for a map and reflections.

Celestial Delights


The Harvest Moon is the name given to the Full Moon closest to the Autumnal Equinox therefore, the Harvest Moon can occur in September or October. This year it occurs September 26 at 12:45pm PDT; 20:45 UT. The Moon rises as the Sun is setting.

A Full Moon near the autumn equinox lies low in the south along an ecliptic that forms a very shallow angle to the horizon. This results in the moon rising very quickly around the time of sunset ... also rising only 20 to 30 minutes between consecutive moonrises instead of the typical 50 minutes. Before electricity this additional light late into the evening allowed farmers more time to gather their harvest. For latitudes farther north the effect is more pronounced with less time between moonrises each night. It is not surprising that the name "Harvest Moon" originated in the northern European latitudes.

The Harvest Moon because of its closer angle to the horizon appears to loom extra large when it rises ... a well known illusion. In fact the moon is actually closer to the earth when it is highest in the sky!

Try this experiment as you watch the moon rise from the horizon to overhead. Place your thumb and index finger a pencil width apart, at arm’s length. You should always be able to fit the moon between your fingers no matter where it is! The moon will always look bigger next to objects than when it is seen overhead in a dark sky.

Current Theories on Moon Illusion

Harvest Moon Images: Michael Myers

... traditionally the Harvest Moon lasts more than one night. And includes the two almost full Moons two nights before the official full Moon and the two almost full Moons two nights after. So we have five nights of the Harvest Moon. Star Gazer 2005 script 9/12–18

September 27, Thursday, the Moon looms larger than usual. It is at perigee, closest to the Earth for this lunar cycle, 223,332 miles, at 6:54pm PDT; 01:54 UT 9/28. It is the third closest Full Moon of 2007. See the Lunar Perigee and Apogee Calculator to find out when the two closer Full Moons occur. BTW: Watch out for those high tides!

May your harvest be delicious and bountiful.
May it serve the greatest good!

Sept. 23 - Oct. 22

Mercury can be seen hugging the southwestern horizon after sunset. The planet, positioned far in the south, gives a poor performance for Northern Hemisphere observers. Mercury reaches greatest elongation 9/29 and inferior conjunction 10/23. It sets in the beginning of Libra 50 minutes after the Sun around 7:50pm. Mercury lost in the Sun's glaring light, sets only 10 minutes after the Sun around 6:40pm by the end of Libra. Mercury is retrograde 10/12-10/31.

Jupiter paired with Antares is sinking toward the southwestern horizon giving us roughly 2 1/2 hours viewing time. Jupiter's steady and brilliant yellowish glow contrasts with the twinkling reddish gleam of Antares positioned below and just west of the planet. Use binoculars to view the planet's 4 Galilean moons. Jupiter sets in the beginning of Libra around 10:30pm and by its end at 9:00pm.

Mars now an evening planet, rises in the northeast at 11:15pm in the beginning of Libra and by its end at 10:30pm. The planet moves toward the south as the morning progresses. Mars lies near the feet of the Gemini Twins, as it moves toward a direct alignment with red Betelgeuse to the south. Map Look for the red triangle formed by Aldebaran, Mars and Betelgeuse; compare the color, brightness and size of each. 10/1-3 a waning Moon transits the triad, first aligning with Aldebaran, then Mars and finally Betelgeuse. Watch Mars grow redder, brighter and bigger as its distance from Earth decreases over the next few months. Mars is at its closest 12/18 and reaches opposition and peak brightness 12/24.

Venus and Saturn are in a stiking predawn encounter along with Regulus, the brightest star in Leo the Lion. Venus, achieving greatest brilliancy 9/23 at magnitude -4.8, is stunning as it first approaches Regulus then Saturn from the west and finally passes both of them to the east. 10/7 a waning crescent Moon joins the trio near Saturn. Map Venus lies very near Saturn 10/13-14. In the beginning of Libra Venus rises at 3:45am followed by Saturn at 4:25am. By Libra's end Saturn rises at 3:15am followed by Venus at 3:30am.

The Big Dipper is in the northwest as night falls. How many evening stars can you still find using Big Dipper Navigation? Its maximum navigation is shifting to the early morning hours.

Vega is the brightest star overhead as night falls. It is the western point of the Summer Triangle and sets well after midnight. Altair is the triangle's southern point and Deneb the eastern point. The Milky Way sweeps through this triangle from teapot-shaped Sagittarius in the southwest to M or W-shaped Cassiopeia the northeast.

The Keystone of Hercules is a fat, four star trapezoid or wedge located about a third of the way from Vega to Arcturus. Draco now lies to the north of Vega and Hercules. The Big Dipper is above this Dragon. Star Map

Fomalhaut is the brightest star low on the southern horizon from 9:00pm to midnight. it is the Southern Royal Star and the brightest star in the constellation Pisces Austrinus below Aquarius. Star Map

Capella is the bright star rising in the northeast about an hour and a half after sunset. Capella is the brightest star seen the most often.
