Just as North America experienced twice-in-a-lifetime solar eclipses in 2017 and 2024, on August 2nd 2027 Europe and Africa will have their turn. The eclipse will start in Morocco, sweep across the Mediterranean Sea, and reach its peak totality in historic Luxor, Egypt. Eclipsophile says, "Cloud cover for this eclipse is among the lowest I’ve analyzed over the last 45 years... Just about anywhere will present a good to excellent opportunity to see this event and bathe in over six minutes of totality." https://eclipsophile.com/tse2027/ If you live anywhere near the path of totality and have never seen a total eclipse of the sun, DO NOT MISS THIS OPPORTUNITY. If you live far away, it's not too early to make travel plans. Many hotels in the path of totality are already fully booked.

Hooray! Dark skies (no moon) interfering with one of the best showers of the year, producing up to 60 meteors per hour at its peak. Although the predicted peak falls during the night of August 12-13, it has a long range: from July 14 to September 1. So, you can start watching for these meteors in the early August morning hours. The Perseid meteor shower is perhaps the most beloved meteor shower of the year in the Northern Hemisphere. It’s a rich and steady shower. These fast and bright meteors radiate from a point in the constellation Perseus the Hero. As with all meteor shower radiant points, you don’t need to know Perseus to watch the shower. Instead, the meteors appear in all parts of the sky, frequently leaving persistent trails. Perseid meteors tend to strengthen in number from midnight to the wee hours before dawn. These meteors are the result of our passing through the tail of Comet Swift-Tuttle. For a while, astronomers calculated that this comet would collide with the Earth during the Perseids in 2126. Such an impact would have spoiled any stargazing since the comet is the largest near-Earth object that periodically passes through our sky. If Swift-Tuttle ever does hit the Earth, its 60 km/s impact will be about 27 times more energetic than the asteroid strike that wiped out the dinosaurs.

To experience greatest totality, you might get a lucky break in the clouds in Greenland or Iceland... but unlikely according to Eclipsophile: "Two-thirds of the Moon’s shadow path falls over water and even a casual glance at Figure 1 shows that ship-borne viewing sites will be challenged to find good weather. Instead, the best observing sites are on land or close to land and of these, Spain and Mallorca are the most promising."

Did you know that Venus has phases, like the Moon? In binoculars you can often see its crescent shape.

The term "Sturgeon Moon" refers to the full moon in August and originates from Native American tribes in North America. They named it after the sturgeon fish, which was abundant and most easily caught in the Great Lakes and other major bodies of water during this time of the year. Ever seen a sturgeon? Living dinosaurs! This fish species dates back to the Late Cretaceous period, around 100 million years ago, making them one of the oldest surviving fish species. Google yourself some 'great lakes sturgeon' pictures. Weird looking, but allegedly one of the tastiest fish in the world.

The Farmer's Almanac described this as the Harvest Moon because it gave farmers several extra evenings of moonlight to allow them to finish their harvests before the frosts of fall arrived. Tender vegetables such as tomatoes, peppers, winter squash, and pumpkins must be picked before the first frost. "Come a little bit closer Hear what I have to say Just like children sleepin' We could dream this night away But there's a full moon risin' Let's go dancin' in the light We know where the music's playin' Let's go out and feel the night Because I'm still in love with you I want to see you dance again Because I'm still in love with you On this harvest moon..." – Neil Young

This is the best time to view and photograph Saturn and its moons. A medium-sized or larger telescope will allow you to see Saturn's rings and a few of its brightest moons. Fun fact: Saturn's rings are relatively new. They coalesced around the same time that trees and sharks were making their first appearance on Earth some 400 million years ago.

The cause of this shower – Comet 21P/Giacobini-Zinner – was at perihelion in March of this year. Will we finally see a storm of Draconid meteors this year? Yes please! The radiant point for the Draconid meteor shower almost coincides with the head of the constellation Draco the Dragon in the northern sky. That’s why you can view the Draconids best from the Northern Hemisphere (and early in the Evening.)

The waxing gibbous moon will set around midnight, so watch for meteors just midnight through the wee hours of dawn. These fast-moving meteors sometimes produce bright fireballs, which might be able to overcome a moonlit glare. If you trace these meteors backward, they seem to radiate from the Club of the famous constellation Orion the Hunter. The Orionids is produced by dust grains left behind by comet Halley, which has been known and observed since ancient times.

This year, a waning crescent moon shouldn't interfere with the show. The Taurid meteor shower, which includes both Southern and Northern Taurids, is known for its long duration, typically lasting from September 28 to December 2, but it generally offers only about five meteors per hour even at its peak. The Taurids are notable for a high percentage of fireballs, or exceptionally bright meteors.The American Meteor Society pointed to “a seven-year periodicity” with Taurid fireballs. 2008 and 2015 both produced them. 2022 did as well. Fingers crossed for 2029? The best viewing times for the Taurids are typically around midnight, when the constellation Taurus is highest in the sky. The Taurids are unusual in having two separate streams: one produced by debris from Asteroid 2004 TG10 and the other from Comet 2P Encke.

The waxing gibbous moon will set shortly after midnight, so wait until then to look for meteors. It peaks this year on the night of the 17th and morning of the 18th Here's a bit of history: The Leonids, typically an average shower, occasionally produces extraordinary meteor storms. In 1966, observers witnessed thousands of meteors per minute during a spectacular 15-minute period on November 17. Meteors seemed to fall like rain, all streaming from the constellation Leo the Lion. This event left a lasting impression of Earth moving through space, amidst a dense meteor stream. While Leonid meteor storms recur approximately every 33 to 34 years, recent occurrences haven't matched the intensity of 1966. Usually, the Leonids peak at 10-15 meteors per hour and are most active after midnight, with the highest numbers just before dawn. The Leonids are unique for their roughly 33-year cyclonic peak, with the last major event in 2001. (So maybe mark your calendars for November 2033?) The shower, resulting from dust grains left by comet Tempel-Tuttle, discovered in 1865, runs annually from November 6-30. While meteors radiate from Leo, they can be seen across the sky.

This is an excellent year for viewing the Geminids. The waxing crescent moon will set early in the evening leaving dark skies for what should be an excellent show. In 2025, we saw 150 multicolored meteors per hour, a significant increase from the typical 120. Since the radiant rises in mid-evening, you can watch for Geminids all night on December 13-14. The days before and after might be good as well. The bold, bright white and slow moving Geminids give us one of the Northern Hemisphere’s best showers. They’re also visible, at lower rates, from the Southern Hemisphere. The meteors are plentiful, rivaling the August Perseids. Most meteor showers are the result of us passing though comet trails. These meteors are the debris left behind by an *asteroid* known as 3200 Phaethon, discovered in 1982. The shower runs annually from December 7-17. Meteors will radiate from the constellation Gemini, but can appear anywhere in the sky.

Were it to impact Earth, it would hit with 1200 megatons of force leaving a 5km impact crater.
