full cold moon

A full Cold Moon will be visible across Canada for the last time this decade

A full Cold Moon rising above the skies in Canada is all the reason you need to look out your window tonight before you head off to sleep, because it'll be your very last chance to witness anything like it this decade. 

The last full moon in December 2019 or the last full moon of the fall season is often called a Cold Moon because of the the long, cold nights at this time of year, according to NASA.

The name was originally chosen by the Algonquin tribes of what is now the northern and eastern United States. 

The last Cold Moon of the decade first became visible on Tuesday evening, and it reached its peak early this morning — at 12:12 a.m. on 12/12.

But thankfully, it's not too late to catch a glimpse.

The large moon will remain visible until early Friday morning, making tonight your absolute last chance to witness a Cold Moon before the next decade arrives. 

According to NASA, the December Cold Moon goes by many different names. 

Europeans once called it an Oak Moon, though today they more often refer to it as the Long Night Moon because it falls close to the winter solstice. 

In Sri Lanka, every full moon is a holiday though this particular moon is called the Uduvapa Poya. 

Other names for the December Cold Moon include the Chang'e Moon (China), the Karthikai Deepam Moon (Tamil Nadu, Sri Lanka, and Kerala) and the Moon before Yule (Europe). 

NASA reports that today's period of daylight is expected to last night hours, 29 minutes and two seconds — making it one of the shortest days of the year. 

Once the sun sets, some of the other planets may also become visible.

"On the evening of the full Moon on December 12, 2019, as evening twilight ends, the brightest planet in the sky will be Venus, appearing as the evening star in the southwest at about 10 degrees above the horizon, with Saturn appearing to the right of Venus," according to NASA. 

So don't forget to look up into that evening sky tonight, Canada. Though if you do forget, you can always catch the next full moon, the Wolf Moon, in the next decade on January 10.
