The Sky This Month – March 2010

Monday, March 1st, 2010

We’re premiering a new feature, The Sky This Month, here and on AFM*Radio!  In addition to our occasional daily report, The Sky Tonight, we’ll also be posting a monthly highlights report, here, and featuring the audio version each month, throughout the month, on AFM*Radio.

Don’t just talk about the stars – Go outside and look at them!

The month of March includes four bright planets, five moon & planet conjunctions, and a whole collection of open star clusters!

Beginning with the planets … Mercury, Venus, Mars, and Saturn are all visible this month!  Two of them grace the evening sky, while the other two pair together at sunset.

Starting with the sunset horizon, you’ll find our brightest planet, Venus, basking in the glow of the setting sun early in the month, and lingering for 30mins to an hour after dark by month’s end.  You can’t miss Venus, shining like a beacon on the west horizon – so bright it’s often mistaken for aircraft and even occasionally reported as a UFO.

Mercury joins the sunset horizon around the 20th.  Like Venus earlier in the month, Mercury starts out on the heels of the setting sun, but inches higher, and closer to Venus, through month’s end.

Once the sun sets, turn to your east horizon where you’ll find Mars as that bright red “star” in Cancer, just beneath the twins of Gemini – or east of Orion, if you’re more familiar with that constellation.  A closer look – with binoculars is best – will reveal the Beehive star cluster nearby.  Keep an eye on this pair through the month – by mid-April (next month,) Mars will appear to slip right past the cluster.

Throughout billions of years, the Moon has held an intrinsic practical and emotional bond with our planet.  Sadly, we are losing the human connection as we keep our eyes fixed on the material and social noise of today’s world.

Every once in a while, something special comes along to remind us to pause and look up at Luna, to consider that constant, though oft-forgot, guidepost for all living things on Earth.

We are proud to announce our next AFM*Radio special event, an audio/visual presentation, Moon-Walking with Rob Self-PiersonJoin us next Tuesday night, Dec. 23 0100 UTC (Dec. 22 8pm ET), when Rob Self-Pierson stops by to discuss his “MoonWalking” experiences and his upcoming Blue Moon Walk.  We’ll feature images, video, an interactive chatroom, and details about how you can participate in commemorating the last Blue Moon of this decade!

Dream a Little Dream – Under the Blue Moon

Wednesday, December 16th, 2009

Blue Moon / You saw me standing alone / Without a dream in my heart …

Actually, I do have a dream …  Blue Moon / I’ll be standing with you / Without a cloud in the sky

For many people, December 31st will mark the last day of another year, just as it ends every year of the Julian Calendar.  But, for sky enthusiasts, this December 31st has poignant meaning, marking the end of a very exciting year of astronomy outreach – the International Year of Astronomy 2009. So, it seems most appropriate that this wonderful year of sharing the night sky should end with a Blue Moon!

But, what is a Blue Moon?  We often use the term to reference a rare event – “once in a blue moon” – but is the Moon ever really blue?

Actually, on rare occasions, the Moon does “appear” blue due to specific atmospheric conditions, thus that reference for rare events.  But, more often, the term “Blue Moon” defines an “extra” Full Moon within a given calendar, an event that can be credited to the Julian/Christian calendar, farming cycles, and the tradition of naming Full Moons, rather than any cosmic phenomenon.

Of course, there never really is any “extra” moon.  The Moon orbits our planet, phasing through New to Full with such consistency that it occasionally clashes with our less-precise, seasonal timekeeping.  This leaves us with an “extra” moon about every 2.7 years – and we account for it with the name “Blue Moon”.  For yearly timekeeping, this Blue Moon occurs as the thirteenth of a twelve-moon calendar; for seasonal timekeeping, it is the fourth of a three-moon season; and more recently, due to an interpretation error in the mid-twentieth century, a Blue Moon is the second Full Moon in a one-month period.

This year’s Blue Moon just happens to fall on December 31 – the last day of the month, the last day of this year, and the final day of a decade.  On that day, I’ll be there to watch it, rising on the east horizon at sunset – big, bright, and full of promise – as I reflect on the successes of a year of star-filled outreach.  And then I’ll return at sunrise, to watch as that same Moon – the last Moon of this century’s first decade – sinks into the west horizon, bringing forth a New Year under the Milky Way and another decade of new discoveries.
