Under Paris skies

For Bastille Day, aka French National Day, we examine not the titular prison that was the site of beginning of the French Revolution, but another building inexorably wrapped up in that powder-keg moment of French history. That dome in the upper right portion of this photo is the Panthéon. Construction of the building—intended to be a church—began in 1758. But by the time it was completed, the French Revolution was in full swing and the new establishment decided that it should instead be used as a mausoleum for distinguished French citizens, which it remains today.

Welcome to the Hoh

Don't let this sunny picture fool you. The Hoh, a temperate rainforest on the western side of Olympic National Park in Washington state, sees between 12 and 14 feet of rain each year, making it one of the wettest places in the continental US. But all that moisture creates a lush, even mystical environment. The forest features a mix of conifers and deciduous trees draped heavily with moss, like the arching big leaf maple in our homepage image. A stroll through the forest will also reveal the massive Sitka spruce and western hemlock that may reach more than 300 feet up into the dense canopy. Below, the woods teem with ferns, lichen, and other vegetation. It's an enchanted forest right out of a fairy tale.

A day to take a moment

'A field of water betrays the spirit that is in the air. It is continually receiving new life and motion from above. It is intermediate between land and sky.' So Henry David Thoreau immortalized Walden Pond, but he could have been describing this calming image from Ežezers Lake in Latvia. Today, the birthday of that famous American advocate for pursuing a simple life is also National Simplicity Day, an annual reminder to unplug, slow down, step back, and consider your life. Thoreau's most famous work (that you probably haven't read since high school), 'Walden,' is his account of the two years, two months, and two days he spent away from society in a cabin in the woods by Walden Pond in Concord, Massachusetts. Through this work he encourages us to take a step back and look for ways to simplify our lives. 'Our life is frittered away by detail…,' Thoreau observed, 'simplify, simplify.'

This advice is as sound today as it was 165 years ago when it appeared in print. Some things you can do to mark the day are unplug from your devices (even this one—eventually); declutter your house; take a walk in the woods; and maybe even reread 'Walden.'

How Quảng Ngãi got its grove back

Could these humble rows of trees prevent a natural disaster? The Vietnamese government hopes so. Mangrove forests like Bàu Cá Cái in coastal Vietnam's Quảng Ngãi Province are an important shield against destructive typhoons that rock the coast each year. Unfortunately, mangrove trees have been depleted over the years by population growth, climate change, and increased use of waters for fish farming. Plantings at Bàu Cá Cái—outlined by bamboo frames to create the neat patterns seen here—have been part of a major initiative to regenerate nearly 10,000 acres of mangrove forest around the country.

Italy's submerged village

A 14th-century church tower peeking above the water offers a clue to the past here at Lake Reschen, in northern Italy. Until the mid-20th century, this site in the Italian Alps was home to the village of Graun, which included some 163 homes. But then in 1939, an electric company announced plans to build a dam and an artificial lake here, which would submerge Graun and part of the town of Reschen. Despite public outcry and delays due to World War II, the towns were eventually submerged in 1950 (with everyone safely removed, of course). These days, the remaining church steeple draws tourists, especially in winter, when the lake is frozen over and visitors can walk across.

High alpine color in Colorado

Songstress Dolly Parton once sang 'wildflowers don't care where they grow,' but we gotta believe the wildflowers growing in Colorado's American Basin, shown here, are pretty delighted with their surroundings. American Basin is in the San Juan Mountains in the southern part of the state, about a 5-hour drive from Denver. Visitors here will find rocky cliffs, streams, unique rock formations, and some spectacular wildflowers. July and August are the best time to see the blooms—it's the time of year when you'll reliably spot the Rocky Mountain columbine (Colorado's state flower), elephant's head, Parry's primrose, and marsh marigold. Bring us back a bouquet, all right?

Mercury in retrograde

Today we're traveling to outer space to catch a glimpse of the Caloris Basin on the planet Mercury. This small planet—about the size of Earth's moon—is riddled with craters, but none as spectacular as the Caloris Basin. This large crater is about 950 miles across and is ringed by mile-high mountains.

Now, the study of space is called astronomy, and that's generally our focus when we feature stars, planets, and galaxies on the Bing homepage. But according to those who practice astrology, you may have been noticing an uptick in confusion or a spate of misfortune lately. Astrologers will tell you that 'Mercury retrograde' could be the culprit. Lasting through July 12, this is one of three times each year that Mercury appears to be traveling backwards—or what's sometimes called Mercury retrograde. This happens due to an optical illusion caused by differences in Earth's orbit relative to Mercury's. Because Mercury is named after the Roman's Messenger of the Gods, astrology associates the planet with communication. Accordingly, during Mercury retrograde, the astrologically inclined expect misunderstandings, scheduling problems, and disagreements to abound.

Welcome to the Ring of Fire

Today we're visiting the pair of volcanoes known as Tolbachik—the flat-topped Plosky (Flat) Tolbachik on the left of our image, and the majestic Ostry (Sharp) Tolbachik on the right, which soars 12,080 feet above the Kamchatka Peninsula in far eastern Russia. These are just two of approximately 160 volcanoes that dot the region; 29 of them, including the Tolbachik complex, are still active. In fact, there is so much volcanic activity here that UNESCO calls the peninsula 'one of the most outstanding volcanic regions in the world,' and has designated it a World Heritage Site.

The Kamchatka Peninsula juts out from the Russian mainland between the Sea of Okhotsk to the east and the Pacific Ocean and Bering Sea to the west. The sparsely populated peninsula makes up the western edge of the Ring of Fire, a chain of volcanoes along the Pacific Ocean that account for 90% of the world's seismic activity. Wild, remote, and primal, Kamchatka is home to an abundance of wildlife: arctic fox, tundra wolves, reindeer, lynx, huge Chukotka moose, and the Kamchatka brown bear that can tip the scales at 1,400 pounds.

There once was a lighthouse from...

Nantucket is the island home of about 12,000 people. But venture to its sandy northern reaches, composed of narrow sand spits and only accessible via 4x4 vehicles, and you might not bump into many folks on your way to this historic—and still very important—lighthouse.

The Great Point Light on the island's northernmost tip traces its origin to 1784, a time when Nantucket was world famous—not so much for appearing in countless (often bawdy) limericks, but as the epicenter of the American whaling industry. Herman Melville wrote that Nantucket whalers once controlled two-thirds of the globe's waters, and to get home, all those whaling ships had to navigate the perilous shoals between the island's north shore and nearby Cape Cod. This lighthouse was the solution, first in the form of a wooden tower that burned in 1816, then a stone version toppled by a storm in 1984. The current structure, built partly with materials from the previous one, was dedicated in 1986 and has been in official operation since.

Take in a show on your Roman holiday

In the hills around Pamukkale, Turkey, you'll find the ancient ruins of Hierapolis, which thrived here as holy and healing destination through Greek, Roman, and Ottoman times. The city was founded as a thermal spa in 190 BCE by Eumenes II, the king of Pergamon and was likely named after the wife of the legendary founder of the Pergamene dynasty, Hiero.

The amphitheater so prominent in this aerial view was built in the second century CE under Roman Emperor Hadrian. Renovated several times over the next 160 years—once to accommodate aquatic shows--the theater would have seated about 15,000 people. An earthquake in 1354 finally toppled the ancient city and it was abandoned until it was excavated by German archeologist Carl Humann in the 19th century. Today, the complex retains some of the best-preserved decorative features of any ancient Roman theater, with friezes of Roman Emperor Septimus Severus and his family, as well as the Greek gods Dionysus, Artemis, and Apollo.
