August Is Ending With a Super New Moon

Look up early in the morning of Friday, August 30, 2019, and you won't see anything but an especially dark sky. That's because the moon is entering the "new" phase of its cycle, meaning it's not visible to the naked eye. Even though you can't see it, this upcoming super new moon marks one of the biggest lunar events of the year, and its effects on the tides will be felt around the world, Forbes reports.

What is a super new moon?

The moon follows a 29.5-day lunar cycle, starting with a new moon and ending with a full moon. As the body orbits the Earth, it moves in and out of our planet's shadow, appearing more or less visible each night. A new moon occurs when the moon falls between the Earth and the sun and its near side is totally dark.

New moons happen regularly, but this upcoming event is special. It's also a supermoon. A moon becomes "super" when it reaches its perigee, or the point in its orbit closest to Earth. On Friday night, the supermoon and the new moon will coincide.

Typically, supermoons are a chance to see the moon at its largest in the night sky, but that won't be the case this week. The super new moon will make its presence known in other ways. Tides are always strongest when the moon is closest to Earth. When the moon enters its new phase, it will have the extra gravitational pull of the sun literally backing it up, resulting in super-charged "king" tides across the half of the Earth it's facing. The teamed-up forces of both celestial bodies will be so strong that the normally placid River Severn in the UK could flow backwards and see 32-foot waves.

When is the super new moon?

The new moon will reach its darkest stage at 6:37 a.m. EST on Friday, August 30. If you go out expecting to see the moon, you'll be disappointed, but the dark sky will create optimal conditions for stargazing. Here are some of the best places on Earth to look at the stars.

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.
