Exploring Imbrium Debris

Daylight Moon

The Moon approaches first-quarter phase in a deep blue twilight sky.

When the Moon is nearly at first-quarter phase, the terminator sweeps across some of the most unusual lunar terrain. Aim your telescope toward the region lying between little Mare Vaporum, and the expanse of Mare Tranquillitatis. There you’ll find oddly furrowed features and a couple of badly beat up craters.

How Blue is the Moon

Even though a “Blue Moon” doesn’t really look like this, it does attract a lot of attention.

Whenever there’s a second full Moon in a month, the phrase “Blue Moon” gets a real work out in the popular press and on-line. Interestingly, that definition of a Blue Moon is of surprisingly recent vintage. What’s more, it’s rooted in a mistake.

My copy of Sky&Telescope’s new Moon globe arrived recently and I’ve been enjoying it ever since. I have a special fondness for lunar cartography.

Talking About the Moon

Recently I did a segment for the show SUPERnova, which is produced by the talented team of Tyler Gamsby and Shannon Hartley for the Royal Astronomical Society of Canada’s Vancouver Centre. The results are viewable above.

This is episode #4. Be sure to check out the other shows too. All are very nicely done and have unusually high production values. SUPERnova is part of the Vancouver Centre’s International Year of Astronomy outreach program.



Gearing Up for a Moon Shot

Taking your own trip to the Moon doesn’t require anything as big and expensive as a Saturn V rocket, but a little equipment will definitely make the voyage more rewarding.

The Moon is unquestionably one of the most appealing sky sights. We’re drawn to it as though some primitive impulse from deep within rises to the surface whenever we see the lunar disk shining from the darkness, like consciousness itself. And it’s simply beautiful. No wonder it’s the subject of countless poems, the lead player in numerous nursery rhymes, and usually the very first target for a beginner’s telescope.
