Full moon, lunar occultation and parade of planets visible tonight
The Wolf moon, the first full moon of the year, was expected to shine bright in the sky Monday night.
The name "Wolf moon" refers to the first full moon after the winter solstice. It's derived from Native American culture. The name is "meant to indicate the fact that around this time of year, wolves howl a lot," said Hunter Miller, astronomy educator at Adler Planetarium.
But that's not all.
Chicagoans will also likely get to witness a lunar occultation of Mars and a parade of planets.
What is a lunar occultation?
A lunar occultation occurs when the moon passes in front of an object, said Miller. An occultation is similar to a solar eclipse — when the moon passes across the sun.
At 8:07 p.m., stargazers in Chicago should be able to see Mars disappear behind the moon. Mars will then reappear on the other side of the moon at 9:17 p.m.
Lunar occultations can happen several times a year, but they only occur every couple of years with each planet, Miller said. Ocultations are also "location specific," so not everybody in all parts of Earth will get to see them.
What can you expect to see?
On Monday night, the full moon is expected to shine brightly high in the sky, with Mars appearing like a star next to it.
Viewers looking closely will be able to spot the dusty red surface of the Red Planet, Miller said.
"It is a pretty unique thing to get to see happen, and always exciting to go out and check out, especially when we have a shockingly clear day in January here in Chicago," Miller said.
However, Mars is only one of a parade of planets that will be visible.
What is a planet parade?
A planet parade occurs when multiple planets are visible in the night sky.
Along with Mars, stargazers will be able to spot Jupiter and Venus, Miller said. Both Jupiter and Venus will also appear like bright stars.
According to Miller, Mars will be biggest and brighter as it nears Earth and approaches opposition, when Mars is on the opposite side of Earth as the sun. The Red Planet will be in opposition Wednesday at 8:32 p.m.
