Explanation: Peering from the shadows, the Saturn-facing hemisphere of tantalizing inner moon Enceladus poses in this Cassini spacecraft image. North is up in the dramatic scene captured last November as Cassini’s camera was pointed in a nearly sunward direction about 130,000 kilometers from the moon’s bright crescent. In fact, the distant world reflects over 90 percent of the sunlight it receives, giving its surface about the same reflectivity as fresh snow. A mere 500 kilometers in diameter, Enceladus is a surprisingly active moon. Data collected during Cassini’s flybys and years of images have revealed the presence of remarkable south polar geysers and a possible global ocean of liquid water beneath an icy crust.

Earth Sky News for February 9th: Moon in front of Cancer

Moon in front of Cancer on February 9

By

Tonight – February 9, 2017 – the almost-full waxing gibbous moon puts the constellation Cancer in the spotlight, but out of view. Demure Cancer the Crab is the faintest of the 13 constellations of the zodiac. You can see Cancer only on dark, moonless nights.

The starry sky is like a great big connect-the-dots book, enabling stargazers to star-hop from brighter stars to more obscure nighttime treasures. And that’s why noticing the stars around the February 9, 2017 moon is important. By about mid-February, when the moon drops out of the evening sky, Cancer the Crab will be showing its delicate starlit figurine in the region of sky in between the Leo star Regulus and the Gemini stars Castor and Pollux.

Identify Regulus, Castor and Pollux now, and you can use them for years to come to help you identify Cancer.

Eclipse coming! Penumbral lunar eclipse February 10-11, 2017

Our featured chart at top shows the moon and Cancer for North American mid-northern latitudes. At nightfall, at mid-northern latitudes from around the world, the stars and planets are similarly positioned. As seen from Europe and Asia, though, the moon on February 9, 2017 is offset toward the Gemini stars, Castor and Pollux. This difference in the moon’s position, relative to the backdrop stars of the zodiac, is due to the moon’s own motion in orbit around Earth.

From the Southern Hemisphere, the differences are due in part to the moon’s movement, and in part to the difference in perspective from one hemisphere to the other. Still, we all live under the same sky, and no matter where you live worldwide, the moon beams in the vicinity of Cancer tonight, with the moon sandwiched in between Castor and Pollux on one side and the star Regulus on the other.

Just remember – although we outline Cancer for you on our chart, you’re not likely to see this constellation in tonight’s drenching moonlight. Notice the stars around it, and come back in a week or so to find the faint Crab when the moon has moved on its way – and left the evening sky dark for stargazing.

Bottom line: The almost-full moon puts the constellation Cancer the Crab in the spotlight – but out of view – on the night of February 9, 2017.

Your Charm for February 9th is The Eye Agate

Your Charm for Today

Today’s Meaning:
The eye represents your will to be loved. The strength of your will controls this aspect. You have neglected needed emotions of love in your life. You cannot expect to be loved if you do not show it.

General Description:
These enati (eye stones) were first worn for protection in the East, but soon the custom of wearing these charms spread to almost all countries. Implicit faith was placed in their reputed magical power to guard the wearer from the dreaded influence of the evil eye. From the very earliest times the imagined influence of the evil eye has struck terror into the hearts of the weak minded, ignorant, and superstitious. The uncanny effect of the eye is produced by cutting through the parallel bands, or layers of the different colours which form the agate.
