Illustration. Comet Hale-Bop orbited the sun in 1997 and became one of the brightest comets in history. It was a lasting “gift”, as it could be seen with the naked eye for over 18 months (a record). 2. Cloud hole – circle opens to heaven Imagine that on a cold day and the horizon is densely cloudy, suddenly, you see a giant hole that you can see through the sky. This phenomenon is called cloud hole. It occurs when a large number of small ice crystals break into the cloud layer causing the water droplets to evaporate. Although explained by the laws of physics, this phenomenon is still extremely miraculous. 3. Mist rainbow looks like albino rainbow When you see this phenomenon, you may think that you have lost the ability to distinguish colors. Stay calm and enjoy looking at it, a foggy rainbow like “brothers” to the albino rainbow. Instead of being made up of water droplets, it is made up of tiny dewdrops. Because they are smaller, they only reflect white, making this phenomenon look quite spooky and mysterious. 4. Lava on Hawaii Beach In May 2018, the Kilauea volcano in Hawaii exploded. It began spewing ash into the air and spewing dense plumes of lava to the Pacific Ocean. It also travels great distances, destroying the largest natural freshwater lake in Hawaii. It also spread to the beaches, filling Kapoho Bay and extending new land nearly a mile into the sea. 5. Comet West near the Sun in 1976 Comet West was described as one of the brightest objects to pass through the solar system in 1976. Its nucleus split into four pieces, providing a spectacular view of its long tail. At the time, it was one of the very few comet breaks observed. 6. Pyroclastic flows produce volcanic lightning When a volcano erupts, it releases pyroclastic flows, a fast-moving stream of hot gas and ash. Sometimes these materials mix and match with extreme heat creating an amazing light show. 7. Rare waterfall rainbow in Yosemite National Park Only a few lucky people have witnessed first-hand the sight of Fallveve Falls in Yosemite National Park turning into a rainbow. This is a great example of what happens when sunlight is reflected on water droplets. These images look edited but nature is really full of color and imagination. 8. Frozen waves detected on the coast of Croatia A violent storm toss these monster waves, which then froze in sub-zero temperatures in 2012. This left the coast of Senj, Croatia covered in hard ice that looked like ice . 9. The desert “revives” and blooms California’s “super blooms” usually happen about once every 10 years. This phenomenon requires a perfect “storm” of conditions: steady rain, warm temperatures and low winds. The desert will turn into a colorful picture when thousands of wildflowers bloom at once. A wonderful gift of nature! 10. Super blood moon rises behind the Parthenon in 2018 A total lunar eclipse that is a supermoon is a relatively rare phenomenon. In the 21st century, there are 87 total lunar eclipses, of which only 28 are supermoons. Skywatchers could see a “bulging” supermoon and a combined lunar eclipse for the first time in decades, the moon now bathed in a fiery red light. 11. Bubble clouds If we see the sky shining as if there are giant soap bubbles floating, we are not hallucinating, but witnessing clouds of bubbles. This phenomenon occurs only when very uniform drops of water diffract the sunset light. 12. Himalayas appear for the first time in 30 years In April 2020, the level of pollution dropped sharply, making the image of the splendid Dhauladhar mountain range again. This is part of the Himalayas and can now be seen even from Jalandhar – 143 miles away. 13. Snow falls in spring in Tokyo Seeing snow in Tokyo is pretty special, but what makes it really surprising is that it happened in April while the cherry blossoms were in full bloom. Tokyo snows about 7.6 times per season, mainly in January and February. And this is the first spring snowfall in 32 years. 14. Midnight sunset reflected in a waterfall in Iceland During the summer months in Iceland, the sun is still visible at midnight local time and we can enjoy the sunset at 1:30. In this photo we can see the sunset shining at 196 feet of Seljalandsfoss waterfall, which is breathtaking!

(Photo: Pandotrip) Normally, Horsetail is a small and dry waterfall because its water is the amount of melted snow flowing down from the top of El Capitan rocky mountain, so little that visitors do not notice, until the phenomenon of Fire Falls appears. If you want to admire this amazing beauty, you have to be at the right time, not at any time. (Photo: Gary Hart) Every year, in just about 2 weeks, from mid-February to early March, when the sun sets, the light shines down on Horsetail waterfall making it glow red, orange and yellow as unique as the name Fire Falls. It is also unique in that during those 2 weeks, Firefall does not happen every day, so people talk to each other, only the “lucky” people can meet. According to Amusing Planet, in order to form Fire Falls, several conditions must be present simultaneously. The first is that the waterfall must be flowing, which means it needs to be warm enough to melt the snow and ice, the falls’ only source of water. (Photo: Stephanie Hager) The second condition is that the western sky must be real during sunset, with no clouds, rain or snow that would block the sunlight on its way to the waterfall. Photographer Michael Frye, author of The Photographer’s Guide to Yosemite says: Horsetail Falls is so amazing that I don’t know of any other waterfall on Earth that can have this light “. (Photo: The LIFE Picture Collection) The beautiful sight at Fire Falls is known to more tourists by sharing pictures on the media. Every year, many tourists and photographers flock here to admire this incredible beauty. The most convenient and frequent place to see the Fire Falls phenomenon is at the El Capitan picnic area. At the end of February, you’ll often find a host of photographers of all levels waiting there to capture the last rays of evening at Horsetail.

The main interface of the travel feature of world heritage sites. According to Google, the cultural tourism sector, which accounts for 40% of the global tourism market, is suffering a lot from the Covid-19 pandemic. The number of tourists in this group has decreased by 75% in 2020 (compared to 2019). The online search giant also cited data from the International Council of Museums (ICOM) as saying that about 90% of museums have had to close, of which 10% may never reopen. In the context of theaters, bookstores, cinemas … being temporarily closed, the revenue of content creators is also reduced by 35% in 2020 – equivalent to about $ 3.5 billion worldwide. bridge. In that context, Google has partnered with UNESCO in launching a new feature, giving users the opportunity to continue exploring places such as the French canals, the Colosseum (Italy), the top of Kilimanjaro and the mountains. Fire in Korea… Tours also include information on globally famous landmarks such as Yosemite National Park, ancient pilgrimage routes in Northern Spain or the great pyramids of Giza in Egypt. Virtual tours are expected to maintain the connection between humanity and important vestiges of world history in the context that global travel is not feasible. Through the virtual tourism service, Google and UNESCO also want to provide valuable resources for educators and schools, thereby helping the teaching of cultural and natural heritage. Virtual world heritage sites are included in the Google Arts & Culture group of cultural content, which includes tours to many major museums, augmented reality (AR) galleries… To access, users can connect to https://artsandculture.google.com/project/explore-world-heritage.
