Thank good­ness for Guy Ottewell. If he did­n’t exist, I would have to invent him.

I don’t know what else Ottewell does for a liv­ing, but one thing he has been doing for decades is put out an annu­al astro­nom­i­cal cal­en­dar of sur­pass­ing orig­i­nal­i­ty. It arrives every year in Decem­ber and, dur­ing ear­ly win­ter evenings, I curl up with the cal­en­dar and plan my com­ing year of stargazing.

Actu­al­ly, Ottewell’s book is more than a cal­en­dar; it is a com­pendi­um of all things astro­nom­i­cal that will hap­pen dur­ing the year, described with a graph­ic flair that is the author’s par­tic­u­lar genius. The cal­en­dar is use­ful for neo­phytes, but it also evokes the appre­ci­a­tion of expe­ri­enced astronomers.

So what’s up this year? A full sched­ule of beau­ty, includ­ing some extra­or­di­nary gifts of grace that no skygaz­er will want to miss.

The year begins with Jupiter and Sat­urn march­ing sin­gle-file across the evening sky. By Feb­ru­ary, Venus is as bright as it ever gets, bright enough to spot with the unaid­ed eye in a deep blue day­time sky. Folks will be call­ing the tele­vi­sion sta­tions ask­ing what is the bright light in the north­west at sunset.

Fred Schaaf, who con­tributes Observers’ High­lights to the Astro­nom­i­cal Cal­en­dar, says that at a very dark site one might see Venus cast a shad­ow. I’ve nev­er seen a Venu­sian shad­ow, but I’ll be in a dark site in Feb­ru­ary — a Bahami­an island — and I’ll be look­ing for it.

By June, Mars will be clos­er and brighter than at any time in the last 13 years, a blaz­ing red-orange ember in the sum­mer sky, exact­ly oppo­site the sun. Then, in July, Venus, and Sat­urn per­form a pas de deux in the morn­ing sky near rud­dy Alde­baran, blow­ing kiss­es across a tan­ta­liz­ing­ly nar­row gap on the morn­ing of July 15.

Two days lat­er, they are joined by the cres­cent moon, and any­body who does­n’t get up to watch that stun­ning appari­tion does­n’t deserve a sky.

Venus changes part­ners in late Octo­ber, danc­ing cheek-to-cheek with Mer­cury in the dawn. On Dec. 1, the full moon pass­es direct­ly across Sat­urn for New Eng­land observers, a sort of mini-eclipse called an occultation.

I’ll be attend­ing oth­er celes­tial events this year in my imag­i­na­tion, with a lit­tle help from Guy Ottewell.

A total eclipse of the moon occurs on Jan. 9, although only for folks in Europe, Africa, and Asia. As the full moon pass­es into Earth­’s shad­ow, we’ll be hav­ing after­noon tea in New Eng­land. So I peruse Ottewell’s dia­grams and maps and imag­ine where I’d like to be for the eclipse.

The Sey­chelles Islands in the Indi­an Ocean would do nice­ly: A few drinks on the ter­race of a nice hotel to accom­pa­ny the balmy mid­night lunar show, the moon shed­ding her bridal white for a chemise of dusky red. But, what the heck, as long as I’m arm­chair trav­el­ing, I might as well go to the moon and watch the eclipse from there: Lunar day turned to lunar night as the sun slips behind the Earth. No one, not even an astro­naut, has seen that before.

The real whiz-bang dra­ma will be the total eclipse of the sun on June 21, four min­utes when the sun becomes a black hole punched in the sky. Solar eclipses occur over nar­row paths of the Earth­’s sur­face. Last year, I was on a ship in the Black Sea to watch a total solar eclipse, but this year I will have to pass. If I could go, I’d stay for a few days at Vic­to­ria Falls, in cen­tral Africa, then take the train up to Lusa­ka, the cap­i­tal of Zam­bia, for the after­noon eclipse — two great won­ders of the world in one trip.

When the sun goes dark in Lusaka’s sum­mer sky, the win­ter stars of Ori­on will be vis­i­ble, with Jupiter near the eclipsed sun between the horns of Tau­rus the Bull. It’s a rare treat to have a bright plan­et so near an ink-pot hole in the sky, and we can antic­i­pate some gor­geous pho­tos from those who are there.

No total solar eclipse will occur in the Unit­ed States till 2017, but, in the mean­time, Ottewell’s neat graph­ics are the next best thing to being there.

The heav­ens are half of our visu­al field. If we don’t pay atten­tion to the sky, we are miss­ing half of the beau­ty of the world. It’s an ever-chang­ing show. I’ve been watch­ing for a life­time and there’s still a chance for some­thing new: This year I’ll be look­ing for that elu­sive shad­ow cast by a plan­et, and try­ing to see how long I can fol­low morn­ing-star Venus into the deep blue of daylight.
