Comparing
and Contrasting Earth and Mars
Mars is at its best during Capricorn, its biggest and brightest until 2016 and its highest until 2040! Approximately once every 26 months observers on Earth experience the opposition of Mars and the Sun in the sky. Image 1, 2 During this Martian biennial peak the Red Planet is at its closest and brightest. In 2007 Mars is technically at its closest December 18 and brightest December 24. Know that the Red Planet looks just as good several weeks before and after those dates. This Mars approach is neither the closest (perihelic) nor the furthest (aphelic). It lies between these extremes at a distance of 55 million miles from Earth with an apparent disk size of 15.9" (arc seconds). The next two oppositions are worse.

Locating Mars Look for Mars rising in the northeast at sunset, overhead at midnight and setting in the northwest at sunrise. Best viewing occurs around midnight, when the planet is at its highest. Note: By the end of Capricorn Mars sets about 2 hours before sunrise. The Red Planet lies to the right (south) of Gemini's Twin stars, Castor and Pollux at almost the same altitude as Orion's bright red shoulder star, Betelgeuse. Find red Aldebaran west of Betelgeuse and you'll see all members of the shape shifting Red Triad. Use this map during December to locate rising Mars and the evening stars between 7pm-8pm (dated spheres represent the Moon on the given date). In 2007, the December 23 highest riding Full Moon until 2023, conjoins / occults Mars in the Sacred Hoop. Christmas Eve Mars keeps our celestial Santa company! Some say Mars will outshine Rudolph's nose! Click Moon Dances for a map and reflections and to learn more about the Sacred Hoop, Full Moon, Mars and Santa.
Mars Is Moving Backward Mars appears to be moving in a westward (backward) retrograde motion toward the horns of Taurus the Bull until 1/30/08, afterwards it moves eastward (forward) again. Mars Path 10/1/07-4/23/08 This apparent zig zag motion occurs, as orbiting Earth catches up to, aligns with and passes orbiting Mars. During this retrograde period (11/15/07-1/30/08), the Red Planet in close proximity to Earth appears bigger, brighter and redder than usual. Orbital Motions of Earth and Mars

Atlas
~ A Computer-Generated “Flying Saucer” Moon
Atlas and Pan ~ Background and Speculations These two moons were first discovered in the early 1980’s by the Voyager spacecraft. Between 2005 and 2007 the powerful cameras aboard Cassini have given an unexpected and surprising saucer-shape view of these two moons! Note: 33-km-wide (21-mi-wide) Pan orbits within the Encke Division, which is a gap found in Saturn’s A ring. 39-km-wide (24-mi-wide) Atlas orbits just outside the A ring. Ring Image

Saturn retrograde (12/19/07-5/1/08) can be seen in the belly of Leo the Lion, east of blue-white Regulus the heart star of the Lion. The planet is now moving westward back toward Regulus. Look Up! Can you see the right angle formed by Saturn, Regulus and Algieba, Leo's neck star? Locate it here. Night owls and early birds can easily view the planet's golden orb and the blue-white star late in the evening and before sunrise. Saturn rises in the beginning of Capricorn at 10:00pm and by its end at 8:30pm. December 27-30 the waning Gibbous lights up Leo the Lion, Regulus the Lawgiver and Saturn the Lord of the Rings and Lord of Karma. Click Moon Dances for a star map and reflections. In the predawn sky the ringed planet can be seen between Mars our evening planet and Venus our morning planet. 1/5 5am Star Map Saturn's orbit is bringing it closer to Earth now. Watch it's golden orb grow brighter and bigger until it reaches opposition 2/24/08. This is also great time to see Saturn's globe shadow on its rings!
Seeking Saturns Ring Shadow Sunlight on the globe of Saturn is creating a shadow that is cast on its rings. The shadow can be viewed increasing on the right side of the rings October, November, December then decreasing on the same side January, February, March just after opposition. At opposition February 24, 2008 Saturn, Earth and Sun are in a straight line. This alignment causes Saturns shadow to be directly behind its globe and invisible to earthlings. After opposition the shadow can be seen on the rings, increasing on the opposite side of the globe. You can view Saturn's ring shadow online; see link/directions below. Note: Earthly atmospheric conditions and the size of one's telescope affect the shadow's visibility. See

SOHO Sees Sun-Hidden Planets ~ So Can You! Mercury and Jupiter hidden by the Suns glaring light are seen from the Solar and Heliospheric Observatory (SOHO). The SOHO spacecraft's coronagraph blocks out the Sun's glare to reveal Sun-hidden objects. Mercury having reached superior conjunction December 17 can be seen moving away from the Sun, passing steadily from right to left in the above coronagraph images. Jupiter, moving in the opposite direction, left to right, is first seen moving toward the Sun then away from it. Jupiter was in solar conjunction December 22. When any planet is lost in the bright glow of our Sun, try viewing it on the SOHO site. First click THE SUN NOW and then click the LASCO C3 (or C2) image. Clicking More LASCO C3 will give you a series of images taken about every half hour or so. Expected Transits gives information about planets and other objects moving through the coronagraph's field of view. The approximate dates to view Mercury's transit across SOHO's coronagraphs are December 2-31. The approximate transit dates for Jupiter are December 12-January 2.
What is a Coronagraph? The Large Angle and Spectrometric COronagraph, LASCO, is a device that creates an artificial eclipse, basically blotting out the brightest part of the Sun so researchers can study the corona, or atmosphere. Learn more about SOHO's two coronagraphs.
Mercury and Jupiter emerge from the Sun's glowing embrace on opposite horizons. Look for elusive Mercury, the star-like planet, after the first week in January, just after sunset, low in the southwest. If you're lucky, you'll see the youngest Crescent Moon above the planet January 9. By January 15 Mercury sets 80 minutes after the Sun, January 21 90 minutes after the Sun.
Look for Jupiter mid-January low in the southeast, just before sunrise. By January 21 Jupiter rising around 6:00am can easily be seen below Venus. Their distance decreases until they are at their closest February 1, a brilliant predawn planetary treat. [Return to Menu at top]

Venus rises above the southeastern horizon in the beginning of Capricorn at 4:15am and by its end at 5:00am. The planet is exquisite with a waning Crescent Moon the mornings of January 3-5 and it is seen near Antares January 6-8. Click Moon Dances for a map and reflections. This gorgeous eye-catching planet is slowly descending toward the sunrise horizon and dimming as its orbit moves it further from Earth. Venus achieved its greatest brilliancy September 23, 2007 at magnitude -4.8, by December 15 the planet's magnitude dropped to -4.2 and by January 15,2008 it drops to -3.9. Though Venus is dimming its presence remains breathtaking. Late sunrises enable more people to observe the decreasing distance between descending blazing Venus and ascending brilliant Jupiter. What a great way to start the day!
Venus transits our thirteenth constellation, Ophiuchus January 6-21. Ophiuchus is the medicine man who has the wisdom of the serpent fire. He represents the ascended one who lives the radiant life. He is the initiate who has turned knowledge into wisdom. Ophiuchus welcomes Venus the goddess of love who understands, harmonizes and fosters universal mind. Together they help humanity remember and manifest the intuitive true love of the Spiritual Presence, Buddhi. They prepare us for self mastery and the great fusion with Spirit. The union of Venus and Ophiuchus is auspicious for the heart of humanity. Their evocative gift is the greater truth of the heart. Look to blazing Venus each new day and align with the medicine of the fiery sacred heart. Know it is shining down upon us during the predawn and daylight hours January 6-21. Look Up!

Is the winter sky brighter? Yes, for two reasons. The first is because there are actually more bright stars in our winter sky than in other seasons. About half of the 25 brightest stars in our sky are visible in the winter, a higher proportion of these bright stars than in any other season. The Winter Triangle and The Great Winter Hexagon are made up of some of the brightest stars in the heavens. The second reason has to do with cold air.
APOD:
November 6, 2002 - The Winter Hexagon
How many stars can we see with the naked eye? Since we can only view one half of the sky at a time, the maximum number of stars we can actually see with the unaided eye under ideal conditions is only between 2,500 and 3,000 (6,000 for the entire sky). In fact, it is said that one could count them all in a matter of a few hours! Taking into consideration the light pollution of our cities the number drastically drops. When we casually Look Up on any night, we do not see "thousands and thousands" or even "billions and billions" of stars in the sky. We are lucky, if we can see hundreds at any given time. Using geometry and a toilet paper tube it's possible to estimate the total number of stars visible to the unaided eye at any one time!
Why do stars twinkle? One of the ways you can tell a bright star from a planet is that planets generally don't twinkle, yet stars seem to twinkle, or change their brightness, all the time. In fact, most of the stars and all the planets are shining with a steady light. So why the twinkle and no twinkle? It has to do with turbulence and apparent surface size. Turbulence, the movement of air in the Earth's atmosphere, causes the point-like image of starlight to shift around and fluctuate in brightness and color. This means that some of the light reaches us directly and some gets bent slightly away as it travels from the distant star through the atmosphere down to us on the ground. To our eyes, this makes the star seem to twinkle. Because planets appear as small disks, not points, the shift amount is only a small percentage of their size. As a result, "twinkleness" is absent. You will notice that stars closer to the horizon will appear to twinkle more than other stars. This is because there is a lot more atmosphere between you and a star near the horizon than between you and a star higher in the sky. Mercury, which stays close to the eastern and western horizons and is point-like, is the only planet that twinkles, flashing a bright yellow color. Go out some night soon. Look Up and check it out!

The New Year's Star is Sirius, the brightest star in the night sky. Every New Years Eve at midnight, Sirius reaches its highest point in the sky directly on the meridian, known as its zenith point. It's as close as it gets to your crown chakra (the top of your head). No matter where you live, just look due south and up to see this dazzling star heralding in the New Year. Star maps If you miss it at New Years, you can still see Sirius in this location through the first week of January. Find Sirius anytime of the evening by Navigating with Orion. BTW: When we look at Sirius we see the light that left it 8 1/2 years ago! The Ageless Wisdom teaches us that the energies and powers of this star are instrumental in our creation and in the establishment of the guiding forces of our planet and the mysteries of Initiation. It has been referred to as the Christ Star. It is also said that a sacred planet is responsive to the life of Sirius. What the Soul is to our personality is what Sirius is to our Solar System. For this reason Sirius is known as the God Star. It is also known as the Dog Star, for it is the brightest star in Canis Major.
These Sirian forces can aid in the service of those who are spiritually attuned. If you are one of these people, just open your crown chakra and allow the evolutionary energies to flow in and take hold. May only the Greatest Good come forth for all of us this New Year!

Sun at Aphelion and Perihelion
Earth and Sun are at their closest on January 2, 2008 at 4:00pm PST; 00:00 UT 1/3. In fact, every January the Earth is at perihelion, the closest to the Sun for the year, and in July it is at apehelion, the farthest away from the Sun for the year. On January 2 we will be only 91.4 million miles away from the Sun, which is 3 million miles closer than when our Earth is at aphelion on July 4, 2008 at 1:00am PDT; 08:00 UT. We are so close to the Sun in January that it can appear 7% brighter than it does in July! So why is it colder in January and hotter in July for the Northern Hemisphere? What's the weather like in the Southern Hemisphere right now? The tilt of the Earth plays a big role in answering these questions. Here's a fun and simple explanation!

Here are a few more Earth/Sun facts as well as a review of perihelion and aphelion. Here's a year to year chart of Equinoxes, Solstices, Perihelion, and Aphelion. BTW: If you have trouble remembering the difference between perihelion and aphelion, an old astronomer's trick is to recall that the words "away" and "aphelion" both begin with the letter "A". Have
a heavenly

Sky Lights ~ Capricorn December 21, 2007 - January 20, 2008 Mars, at its closest 55 million miles from Earth 12/18, remains close and big throughout Capricorn and also very bright. It reaches opposition and peak brightness 12/24, when it is out all night long, rising in the northeast at sunset, positioned directly overhead at midnight and setting in the northwest at sunrise. Best viewing occurs around midnight. The Red Planet lies in the Gemini Twins, almost in a direct alignment with red Betelgeuse to the south. Find red Aldebaran west of Betelgeuse and you'll see all members of the shape shifting Red Triad. Mars is retrograde through 1/30/08. Mars Path 10/1/07-4/23/08 In the beginning of Capricorn Mars sets around sunrise and by its end about 2 hours before sunrise. Saturn retrograde (12/19/07-5/1/08) can be seen east of Regulus the heart star of Leo the Lion. The ringed planet lies between Mars our evening planet and Venus our morning planet. 1/5 5am Star Map Saturn's orbit is bringing it closer to Earth now. Watch it's golden orb grow brighter and bigger over the next two months as it reaches opposition 2/24/08. In the beginning of Capricorn Saturn rises at 10:00pm and by its end at 8:30pm. Venus is dazzling in the southeastern morning sky, as it slowly descends toward the sunrise horizon. The planet is dimming as its orbit moves it further from Earth. Mid-January begin looking for Jupiter low in the southeast below Venus. Watch this brilliant pair of predawn planets move closer to each other until they reach their conjunction 2/1. Venus rises in the beginning of Capricorn at 4:15am and by its end at 5:00am. Jupiter is in exact conjunction with the Sun 12/22. Mid-January begin looking for Jupiter low in the southeast, just before sunrise. By 1/21 Jupiter rising around 6:00am can easily be seen below Venus. Their distance decreases until they are at their closest 2/1. Mercury reached superior conjunction 12/17. After the first week in January begin looking for the elusive star-like planet low in the southwest, just after sunset. By 1/15 the planet sets 80 minutes after the Sun, 1/21 90 minutes after the Sun. Fomalhaut is the brightest star low on the southwestern horizon setting at 9:00pm in the beginning of Sagittarius and at 7:30pm by its end. Fomalhaut is the Southern Royal Star and the brightest star in the constellation Pisces Austrinus below Aquarius. It is part of the celestial sea constellations. Star Map Vega, the brightest star in the northwest, sets at 9:00pm in the beginning of Capricorn and by it end at 7:30pm. It is the western point of the Summer Triangle which is slowly sinking on the western horizon. Altair is the triangle's southern point and Deneb the eastern point. The Northern Cross stands upright on the northwest horizon in the early evening. Star Map Deneb, the top of the cross, is also the eastern point of the Summer Triangle, the tail of Cygnus the Swan. Capella is the very bright star high in the northeast as the sky darkens. It is the brightest star seen the most often. It lies in the constellation Auriga, our celestial Santa. It lies north of the Pleiades. Star Map The Pleiades, a mini dipper-shaped star cluster, can be seen south of bright Capella. The sparkling Pleiades are the shoulder of Taurus the Bull. Below, to the southeast, lies the bright red Bull's eye, Aldebaran. Star Map Orion The Hunter, the cosmic giant, rises in the east at sunset. Use his belt stars to locate Sirius and Aldebaran and Betelgeuse and Rigel. Notice the colors of these 4 stars. Navigating with Orion Orion also helps one find the Winter Triangle and the Great Winter Hexagon. Sirius the brightest star in the heavens rises around 7:30pm at the beginning of Capricorn and by 6:00pm at its end. Sirius, the New Year's Star, can be seen high overhead in the south at midnight during the first week of January.
