2020 is your year to see Capricornus

Chart showing Jupiter and Saturn between triangular Capricornus and Sagittarius.

This chart works for September 9 or 10, 2020 … and for lots of nights after that, approximately through late September. Chart via Guy Ottewell’s blog.

Above is a chart showing the night sky on Wednesday, September 9, 2020. See how Jupiter and Saturn are pointing to the constellation Capricornus the Sea Goat? You need a dark sky to see this constellation, but Jupiter and Saturn are very bright. If you have that dark sky, and have never seen this faint constellation, now is the time to look.

Below you’ll find is an example of the unhelpful sky charts generally used in the astronomy columns of newspapers and popular magazines.

It’s from Sunday’s Guardian. The article rightly says that Capricornus is an important constellation because it is part of the ancient zodiac, but it is inconspicuous, and you can at present use Jupiter and Saturn as pointers to it.

Fair enough. But the chart doesn’t do Capricornus justice. Perhaps you, sage reader, can with effort decipher the Guardian’s chart because you know the sky. But, if you were a beginner, could you use this maze of dots and lines to find anything as you gaze at the sky? I don’t think so.

I think the way of connecting dots is derived from H.A. Rey’s ingenious but doomed method as described in his book “The Stars: A New Way to See Them.” It tries to make Capricornus look like a goat. But Capricornus doesn’t look like a goat; it looks like a boat, or – as the Americans prefer – an arrowhead.

I hope my way of rendering this part of the sky – as seen on the chart at the top of the post – is more helpful.

Bottom line: In 2020, the bright planets Jupiter and Saturn can help you find the faint constellation Capricornus the Sea Goat.
