Fantastic February Skies

Starwatch

February stargazing is fantastic for many reasons. Sure, it’s not as comfortable for stargazers living in the winter cold, but the extra special celestial jewels make it worth bundling up for.

If you’re not already in the darker countryside, try to get out there. But even with light-polluted skies, I know you’ll still like what you see.

February kicks off with a comet. It may be visible to the naked eye, especially in the countryside, but you’ll probably be able to see it with a small telescope or a really good pair of binoculars.

It’s Comet ZTF (C/2022 E3), named after the Zwicky Transit Facility based in California. ZTF will make its closest approach to Earth on Feb. 2, about 26 million miles away, and that’s when it will be at its brightest. The comet will be about 10 degrees, or about the width of your fist held at arm’s length, from Polaris, the North Star, in the constellation Ursa Minor.

Unfortunately, there will be a full or nearly full moon simultaneously, making spotting the comet more difficult. Before Feb. 5, the night of the full moon, your best chance of spotting ZTF will be about one to two hours before morning twilight. By that time, the moon will be set or very close to sinking below the horizon. After Feb. 5, look for the comet as early as possible in the evening before the waning full moon rises.

Through February, ZTF will track southward from night to night through the constellations Auriga, Taurus and Orion but will fade as it does.

A general word of caution about comet visibility. Predicting how bright or dim a comet will be is very tricky!

Look in the Butler early evening southern sky, and I know you’ll say, “Wow!” You’ll get an eyeful of bright stars and constellations, what I call “Orion and his gang.”

The majestic constellation Orion the Hunter is standing more or less upright. Its visual calling card is his belt, made up of three bright stars lined up perfectly in a row. Below his belt are three fainter stars lined up to make the hunter’s sword. You can’t help but notice that the star in the middle seems fuzzy. That’s because it’s not a star but a massive cloud of hydrogen gas, being lit up like a fluorescent light powered by the energy of new stars forming within it. Click on the Orion Nebula in the Sky Guide app to find out more. It’s a great telescope target!

Several bright constellations surround Orion. There’s Taurus the Bull with the bright Pleiades star cluster. There’s also Gemini the Twins, Auriga the Charioteer, Lepus the Rabbit, and Orion’s hunting dogs, Canis Major and Minor. Canis Major is the home of Sirius, the brightest star in the night sky.

We have three planets in the February evening skies. One of them is the bright planet Mars with its easy-to-see orange-red glow, visiting the bright winter constellations this year. It’s parked just to the lower left of the Pleiades star cluster in the high southern sky. In December, Mars was super bright and close to Earth, just under 51 million miles away. At the start of February, Mars will be just over 82 million miles away and will move farther away as the month continues.

As bright as Mars is, it isn’t a really good telescope destination, but you might see some fuzzy surface features. On Feb. 27, the first quarter (half) moon will be just to the right of Mars, almost “touching” it. If you happen to be in the Arctic, the moon will actually pass in front of Mars.

Jupiter is a much better telescope target, perched in the lower southwest sky just after twilight. It’s beginning its slow exit out of the evening sky, so you want to get a good look at it as early in February as possible. It’s also getting farther away from Earth, but since it’s such a giant, you can still easily see up to four of its largest moons as they orbit Jupiter. Make sure you view Jupiter early in the evening because by 8 p.m., Jupiter will be getting close to the horizon and the blurring effect of the thicker layer of Earth’s atmosphere.

Venus is by far the brightest planet in the February evening skies and is on the rise, beginning the evenings higher and higher above the southwest horizon. As brilliant as it is, Venus is a useless telescope target because of its complete cloud cover. However, Venus will perform an awesome naked-eye show with Jupiter in late February and early March as the two bright planets approach each other in the early evening southwest sky. On March 1, they will be at their closest to each other, only a half degree apart.

Happy Stargazing and comet hunting this February!
