The Mental Floss Guide to the November Night Sky

November is a great month for skywatching with two dazzling meteor showers, the rare view of a tiny planet, and an eerie celestial meeting of two bright worlds. None require telescopes or sophisticated knowledge of the sky above. If you have eyes, live on Earth, and want a good dose of the cosmos, you're in for a treat. Here are a few highlights that skywatchers should be on the lookout for.

NOVEMBER 4: FIREBALL SEASON BEGINS

The Taurid meteor shower dominates the early part of November, with the northern and southern hemispheres each getting their own shows. The South Taurids peak after midnight on November 4. The North Taurids peak at the same time, but on different days: the 10th going into the 11th. The source of the Taurids is the debris field of the comet Encke. The meteor stream is massive and spread out, with the gravitational influence of Jupiter, most notably, causing a split and thus the dual peaks.

Meteors, though appearing to be massive chunks of rock coursing toward Earth, are generally dust- or sand-sized particles that burn brightly as they slam into the atmosphere. The Taurids tend to be a bit larger than most, frequently producing what are called "fireballs" (really bright meteors). While you won't see many Taurid meteors per hour (around seven or so at best), what the shower lacks in quantity it makes up for in quality. If you have low levels of light pollution and your eyes are adjusted to darkness, you should be in for quite a show.

NOVEMBER 13: THE JV TEAM DEBUTS

On November 13, Venus and Jupiter will appear alarmingly close in the pre-dawn sky, practically as a single object, separated by a mere 0.3 degrees. But don't worry, the planets aren't colliding. Rather, it's a trick of perspective. Venus is about the size of Earth (it is, in many ways, our evil twin), and is one planet closer to the Sun than Earth in its orbit. It is a stunning, unblinking dot in the sky. Jupiter, meanwhile, is about five times farther from the Sun than is the Earth, but what it lacks in distance, it makes up for in size: you could fit about 1300 Earths inside of it. What makes their conjunction so fun is that you don't have to know much about space or astronomy to see the magic of orbital mechanics. How to see it: One hour before sunrise, look east. The two bright, eerily adjacent worlds will appear on the horizon. As the sun rises over the next hour, it will wash them out, so have coffee with you and enjoy the moment.

NOVEMBER 17: THE BEST METEOR SHOWER OF THE YEAR PEAKS

After midnight on November 17, the Leonids meteor shower will peak, and here is why you need to see it. 1. It coincides with a new moon, which means there will be no moonlight to wash out the sky. 2. This shower has a history of delivering the goods, some years bringing as many as 1000 meteors per minute. Note: This is not one of those years! Expect between 10 and 20 per hour, which still isn't bad when the sky is inky black, a celestial canvas waiting for brushes of light. (Incidentally, while the Taurid meteors collide with Earth's atmosphere at a snail's pace—a mere 65,000 miles per hour—the Leonids do not play around. They're smashing into us at a blistering 160,000 miles per hour.) 3. The 17th is a Friday and you can sleep late the next morning, so what are you going to do: Binge-watch somebody else's adventure on Netflix, or go live your own?

NOVEMBER 24: MERCURY SHINES AT ITS BIGGEST AND BRIGHTEST

Mercury will reach greatest eastern elongation, meaning it will be as far from the Sun as it can get for the rest of the year, relative to the Earth, and will thus be as big and bright as it's going to get in the sky. If you want to see the elusive little planet, this is your big chance. Just before sunset, look west. You will most easily see Saturn not too far above the horizon. As the minutes move forward and the sky slowly darkens, you'll notice another bright spot below Saturn. That's Mercury. Enjoy it while you can, because you'll only have about 30 minutes from its first appearance before it sinks below the horizon and thus falls out of view.

If bad weather ruins any of your November viewings, do not fret. Next month we've got meteor showers, pagan rituals, and supermoons to help bid 2017 adieu.

With the colder months just around the corner, you might want to start thinking about investing in an indoor or outdoor heater. Indoor heaters not only provide a boost of heat for drafty spaces, but they can also be a money-saver, allowing you to actively control the heat based on the rooms you’re using. Outdoor heaters, meanwhile, can help you take advantage of cold-weather activities like camping or tailgating without having to call it quits because your extremities have gone numb. Check out this list of some of Amazon’s highest-rated indoor and outdoor heaters so you can spend less time shivering this winter and more time enjoying what the season has to offer.

The Northern Lights Could Be Visible Over Parts of the Northern U.S. This Week

You don't need to live north of the Arctic Circle to see the northern lights. On rare occasions, the phenomenon is visible from upper parts of the contiguous U.S. That will be the case this week, when the aurora borealis lights up skies above Maine, Michigan, and other states across the northern border.

As Thrillist reports, the Space Weather Prediction Center has forecast G1 and G2 geomagnetic storms for Sunday, September 27 through Tuesday, September 29. A geomagnetic storm occurs when activity on the sun shoots solar particles toward our planet. At high latitudes, those particles react with gas molecules in the Earth's atmosphere, resulting in waves of green, pink, blue, and purple light undulating in the night sky.

Normally auroras are limited to the poles, because that's where the concentration of magnetic energy is the strongest. It takes an especially potent solar storm to make the spectacle appear farther south, and that's exactly what's been predicted for early this week. The first storm, a G1 or minor level, is set to last from September 27 through the 28th. It will be followed immediately by a G2 or moderate-level solar storm on September 29.

Northern lights from the G1 storm have already been spotted in Minnesota, and the aurora from the G2 storm is expected to extend even lower. States that have a shot at catching the northern lights on Tuesday include Idaho, Iowa, Maine, Michigan, Minnesota, Montana, New Hampshire, New York, North Dakota, South Dakota, Vermont, Washington, and Wisconsin.

If you don't live within the range of September's light show, there will still be plenty of reasons to look up in the coming weeks. Here are some celestial events to look for in October.
