What's Up for February?
This month we follow the Moon
to three different points of interest in the winter sky.
First up, excitement about the Red Planet is building
as NASA prepares to land its latest rover there,
called Perseverance, on February 18th.
You'll find Mars high in the west
after sunset all month long.
It should be visible all evening,
setting around, or soon after, midnight local time.
On the night of NASA's planned Mars landing,
you'll find the half-full Moon right next to the Red Planet.
So go out and have a look with your own eyes –
especially if you were one of the nearly 11 million people
whose names traveled to Mars with Perseverance,
etched into one of three microchips.
[whoosh]
Staying with the Moon in February,
it next drifts through part of the sky
that contains a familiar pattern of stars,
also called an asterism.
This is the Winter Circle, or Winter Hexagon –
a ring of six bright stars
that spans a very wide region of the sky.
The Winter Circle contains
two other special groupings of stars:
the constellation Orion,
and another wintertime asterism, the Winter Triangle,
made of the bright stars Sirius, Betelgeuse, and Procyon.
Like their counterpart, the Summer Triangle,
the Winter Circle and Winter Triangle
are signposts of the season.
In the Northern Hemisphere,
you'll see them rising in the east early in the evening
during the time of long, cold nights,
and setting in the west
earlier and earlier as the season turns to spring.
Watch on February 20th through the 22nd,
as the Moon moves across the Winter Circle,
growing a bit fuller each evening.
[whoosh]
Finally, the Moon continues on its journey,
visiting the twins of Gemini.
Unlike asterisms, Gemini is one of
the 88 official constellations used by astronomers
to help them describe the locations of objects in the sky.
The two bright stars Castor and Pollux
form the heads of the inseparable twins
from Roman and Greek mythology
for which the constellation is named.
On February evenings,
Gemini is located high overhead in the south.
On the 23rd the Moon is here, just below Pollux.
NASA also has a history with Gemini,
as it was the name of the human spaceflight program in the 1960s
that tested technology and capabilities in
preparation for the Apollo missions to the Moon.
But while the constellation is pronounced "JEM-in-eye,"
not everyone knows the name of the NASA program
was usually pronounced "JEM-ih-knee"
within the space agency.
However you want to pronounce it is fine.
Just make sure you go out
and catch the Moon's visit with Gemini on the 23rd.
[whoosh]
Here are the phases of the Moon for February.
