Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.
Explanation: Galactic or open star clusters are young. The swarms of stars are born together near the plane of the Milky Way, but their numbers steadily dwindle as cluster members are ejected by galactic tides and gravitational interactions. Caught in this telescopic frame over three degrees across are three good examples of galactic star clusters, seen toward the southern sky’s nautical constellation Puppis. Below and left, M46 is some 5,500 light-years in the distance. Right of center M47 is only 1,600 light-years away and NGC 2423 (top) is about 2500 light-years distant. Around 300 million years young M46 contains a few hundred stars in a region about 30 light-years across. Sharp eyes can spot a planetary nebula, NGC 2438, at about 11 o’clock against the M46 cluster stars. But that nebula’s central star is billions of years old, and NGC 2438 is likely a foreground object only by chance along the line of sight to youthful M46. Even younger, aged around 80 million years, M47 is a smaller and looser star cluster spanning about 10 light-years. Star cluster NGC 2423 is pushing about 750 million years in age though. NGC 2423 is known to harbor an extrasolar planet, detected orbiting one of its red giant stars.

The Moon’s current phase for today and tonight is a Waning Gibbous Phase. This is the first phase after the Full Moon occurs. It lasts roughly 7 days with the Moon’s illumination growing smaller each day until the Moon becomes a Last Quarter Moon with an illumination of 50%. The average Moon rise for this phase is between 9pm and Midnight depending on the age of the phase. The moon rises later and later each night setting after sunrise in the morning. During this phase the Moon can also be seen in the early morning daylight hours on the western horizon.
The Waning Gibbous on February 18 has an illumination of 97%. This is the percentage of the Moon illuminated by the Sun. The illumination is constantly changing and can vary up to 10% a day. On February 18 the Moon is 16.51 days old. This refers to how many days it has been since the last New Moon. It takes 29.53 days for the Moon to orbit the Earth and go through the lunar cycle of all 8 Moon phases.
The 8 Lunar Phases
There are 8 lunar phases the Moon goes through in its 29.53 days lunar cycle. The 4 major Moon phases are Full Moon, New Moon, First Quarter and Last Quarter. Between these major phases, there are 4 minor ones: the Waxing Crescent, Waxing Gibbous, Waning Gibbous and Waning Crescent. For more info on the Moon Cycle and on each phase check out Wikipedia Lunar Phase page.

Purify yourself first. You can do this by meditating, or taking a ritual bath. One way is to, try to keep the water flowing, possibly by leaving the bath plug half in, or by having a shower. This reinforces the idea of washing away any impurities so you are not sitting in your own psychic rubbish. (Scent your bath water with your selection of a sacred or special herb or oil.) Ideally, your towel – if you choose to use one – should be clean and used only for the purpose of your ritual bath.
• • Wear something special if you can, something that you only wear during a ritual or working. You can always add a pretty scarf or a throw in the correct color for your working. This sets apart spell working from everyday confusion.
• • Decide on the extent of your circle, which should be formed in front of your altar. Purify this space by sprinkling the area with water followed by salt – both of these should have been blessed.
• • Sit quietly for as long as you can inside the area that will become your circle.
• • Imagine a circle of light surrounding you. This light could be white, blue or purple. If you are in a hurry and cannot purify and cleanse fully, reinforce the circle of light by visualizing it suffused with the appropriate color for your working.
• • Circle the light around, above and below you in a clockwise direction, like the representation of an atom. Feel it as a sphere or as a cone of power. Sense the power Remember to leave a ‘doorway’ through which your magic energy may exit. You should always feel warm and peaceful within your circle.
• • Use your own personal chant or form of words according to your own belief system to consecrate your circle and banish all evil and negative energy, forbidding anything harmful to enter your space. Remember, you are always safe within your circle if you command it to be so.
• • If appropriate, invite the Gods and Goddesses to attend your circle and magical working.
• • Relax and be happy.
If you wish, you can use objects on the ground to show the boundaries of the circle, such as candles, crystals, cord, stones, flowers or incense. The circle is formed from personal power. This may be felt and visualized as streaming from the body to form a bubble made of mist, or a circle of light. You can use the athame (ritual dagger) or your hands to direct this power.
The cardinal points of the compass may be denoted with lit candles, often white or purple. Alternatively, place a green candle at the North point of the circle, yellow candle at the East, red candle at the South and blue candle at the West. The altar stands in the centre of the circle, facing North in the direction of power.
