The Orionid Meteor Shower Will Peak on Monday Night

If you missed Halley's Comet's last trip through the inner solar system in 1986, you'll have to wait a while to catch its next appearance. The comet is only visible from Earth every 75 to 76 years. Though the comet itself is elusive, the debris from its tail lights up the night sky on a regular basis. To view the Orionid meteor shower when it peaks today—Monday, October 21, 2019—here's what you need to know.

What Are the Orionids?

As Halley's Comet propels through our solar system, it drags a trail of rocks and dust behind it. The tail is vast enough to a leave thick band of space debris in its wake. Every October, our planet passes through this rocky field, producing brilliant "shooting stars" as the meteors burn up in the atmosphere. From Earth, the meteor shower appears to originate from the constellation Orion, which is how it got its name.

When to See the Orionid Meteor Shower

The Orionids are visible from Earth starting in the beginning of October, but they don't peak until the latter half of the month. This year, the meteor shower will be brightest the night of Monday, October 21 and the morning of Tuesday, October 22. The moon will be around its last quarter phase at this time, which means that bright skies could wash out the light show for many. But if you wait until the hours leading up to dawn, when the moon sets and skies are darkest, you may be able to spot the shower.

To see it, make sure you're in an area with clear, open skies and minimal light pollution. Whether you live in the Northern or Southern hemispheres, you should be able to experience the phenomena if conditions are optimal.

How to See Venus and the Moon Share a ‘Kiss’ in a Rare Astronomical Event This Week

Venus is visible in the evening or morning sky for most of the year, but this Thursday, the second planet from the sun won't be alone in its spot above the horizon. As Travel + Leisure reports, Venus, also known as the "evening star," will appear right next to a crescent moon following the sunset on February 27, resulting in a rare celestial "kiss."

Why will Venus be close to the moon?

Venus is often among the first "stars" to become visible at twilight (though it's really a planet), and it's the brightest object in the night sky aside from the moon. Between January 1 and May 24, it shines brightly above the western horizon. For a few weeks in early May and late June, Venus is washed out by the light of the sun, and from June 13 to December 31, it's easiest to see in the eastern sky around sunrise.

This week, Venus will be in the perfect position to share a "kiss" with the night's brightest object. All the planets, including Venus, appear to traverse the same path across the night sky called the ecliptic. The moon follows a similar trajectory, and on some nights, the celestial body seems to come very close to the planets that also occupy the plane. This effect is just an illusion; while they will appear to be nearly touching on Thursday, the moon will actually be 249,892 miles from Earth on February 27, while Venus will be 84 million miles away.

The Moon just entered its "new" phase on Sunday, and it will only be partially illuminated by the time it meets up with Venus. The waxing crescent moon will rise in the perfect position in the western sky on Thursday to create a joint spectacle with our planetary neighbor.

When to see Venus and the moon "kiss"

The kiss between the moon and Venus can be spotted in the hours after sunset on Thursday, February 27. When you notice it getting dark, head outside and look to the southwest horizon if you live in the Northern Hemisphere. That will give you your best chance at catching the special event. If you miss it this week, you won't have to wait long for your next opportunity to see the Moon kiss Venus: The two bodies will return to a similar position on March 28, 2020.

The Moon Will Make Mars Disappear Next Week

On Tuesday, February 18, the moon will float right in front of Mars, completely obscuring it from view.

The moon covers Mars relatively often—according to Sky & Telescope, it will happen five times this year alone—but we don’t always get to see it from Earth. Next week, however, residents of North America can look up to see what’s called a lunar occultation in action. The moon's orbit will bring it between Earth and Mars, allowing the moon to "swallow" the Red Planet over the course of 14 seconds. Mars will stay hidden for just under 90 minutes, and then reemerge from behind the moon.

Depending on where you live, you might have to set your alarm quite a bit earlier than you usually do in order to catch the show. In general, people in eastern parts of the country will see Mars disappear a little later; in Phoenix, for example, it’ll happen at 4:37:27 a.m., Chicagoans can watch it at 6:07:10 a.m., and New Yorkers might even already be awake when the moon swallows Mars at 7:36:37 a.m.

If you can’t help but hit the snooze button, you can skip the disappearing act (also called immersion) and wait for Mars to reappear on the other side of the moon (called emersion). Emersion times vary based on location, too, but they’re around an hour and a half later than immersion times on average. You can check the specific times for hundreds of cities across the country here [PDF].

Since it takes only 14 seconds for Mars to fully vanish (or reemerge), punctuality is a necessity—and so is optical aid. Mars won’t be bright enough for you to see it with your naked eye, so Sky & Telescope recommends looking skyward through binoculars or a telescope.

Thinking of holding an early-morning viewing party on Tuesday? Here are 10 riveting facts about Mars that you can use to impress your guests.
