Wind turbines in a moonlit night. They have their own issues but far less problematic than fossil fuels. Unfortunately the Coal fire still makes ~ 41% of global electricity generation and natural gas makes 22%. Hydro power accounts for 16% and Nuclear is 11%. All green renewables, like wind, solar and geothermal, currently generate only 9% of the planet electricity but they contribute more every year as this new era attracts more investors. There are claims for wind turbines impacting birds and bats and creating noise to nearby residents but their major issue has been aesthetics aspect and change of the visual landscape specially in scenic and heritage sites … #timelapse#renewableenergy#windpower#climatechange#nightphotography#twanight@twanight@natgeoimagecollection

Since the earliest Stone Age forms of art we have used light to express ideas. There are a number of annual Light festivals around the world. This is a very artistic one in September called LUMINA that happens in Cascais near Lisbon. Walking at dark under these modern conceptual outdoor art installations was an unusual experience, standing next to this historic citadel walls. In 1878 the first-ever electric lights in Portugal was installed here … #cascais#luminafestival#nightphotography#lightfestival@natgeoimagecollection

One of the most stunning archeological sites I have visited is this complex of 2500-year old tombs of ancient Persian kings (Achaemenid empire) near Persepolis and Shiraz in southern Iran. The time-exposure image has captured the rotation of sky in form of star trails around the north celestial pole, marked by the north star Polaris right above the cliff, during the course of one hour. The cross shaped tombs are each bout 20 meters long and are built into a cliff 60 meters high.

Scattered rocks on the barren Mars-like landscape of Atacama Desert, just before sunrise. Swipe left for the entire panorama. This is as close to Mars as I can get to. When I was working as a science journalist I was obsessed with the Red Planet exploration stories. There are so much mysteries to unfold in our neighboring planet. This is a tribute to @nasa Opportunity Mars Rover mission which was officially ended this week after 15 years, “lived” longer on the surface of Mars than any other robot, far exceeded the original 90-day mission. It survived a dust storm in 2007 but a second one in 2018 blocked even more sunlight and energy, the end for the rover which drove a total of 28 miles (45 km) over years, the record for longest drive on another world. Its twin rover Spirit, on another side of the planet, was also a die hard that worked 5 years in extreme Martian environment. Incredible engineering and science achievement by the mission team at @nasajpl and leadership of my friend and mentor @firouz_michael_naderi who was NASA’s Mars program director in the 2000s which led to unprecedented 6 consecutive successful missions to #mars#nasajpl#spaceexploration#solarsystem#marsrover#atacama@natgeoimagecollection@esoastronomy@tweetsoutloud

Rugged peaks of the Sierra Nevada mountains in California and closeup of the Milky Way in the tail of the celestial Scorpion, a single-exposure photograph with Sigma 105mm telephoto at f1.4! An image that was impossible to capture on a single frame with the older equipment. Followers frequently ask about my night sky photography gears. The @sigmaphoto Art Series lenses are in my favorite list because of fast aperture and high quality sharp image even when used at wide open aperture. Last summer I tested both 105mm 1.4 and the lighter 135mm 1.8 Sigma Art lenses for the first time and was amazed by their perfection. Although such focal length is often used for portraits and most nightscape photographers prefer super wide-angles of 14mm to 16mm, I find the higher focal length of 35mm to 135mm very useful for surreal views of the sky details above a far foreground.

Sound on and enjoy this minute of nature’s spectacular show in the far north, as captured across the entire sky with a fisheye lens. It was 2015 March 17 when the strongest aurora borealis in years, appeared in the Earth sky. I was in Iceland for my annual aurora photo workshop when I noticed particles of a major solar storm is on the way to the Earth. The lights began to dominate the sky early in twilight and continued the entire night with several crowns forming overhead. This timelapse video shows the first two hours of the night. It’s far more amazing to watch this fulldome clip inside a large planetarium. The soundtrack is a courtesy of @alirainimusic in Munich. … #aurora#fisheye#fulldome#astrophotography#twanight@twanight

Swipe left to see the entire panorama. Stars emerge into a colorful dusk above a massive stack along the Great Ocean Road in Australia (photographed in 2015). An adventurous story happened here 3 decades ago. Erosion by the Southern Ocean gradually changes the soft cliff limestone to caves, then arches which collapse to stacks. Located in the Port Campbell National Park this rock was formerly known as London Bridge. Until 1990 it has a complete double-span natural bridge. The sharp edge facing you was connected to the main land with an arch. When it collapsed in January 1990 left two tourists stranded on the outer span before being rescued by police helicopter. The bright “star” in the second slide is planet Venus. The yellow light on the clouds in the far right (third slide) is light pollution from two nearby gas plants in Waare, Victoria … #twanight#greatoceanroad#portcampbell#panorama#nightphotography@twanight@natgeoimagecollection

In a long exposure image, bright winter stars move across the sky over the span of one hour, creating star trails, over a natural wonder of Qeshm Island in the Persian Gulf, known as the Valley of Stars. Note the subtle colors of trails, representing the temperature of stars with white blue the hottest and youngest and orange-red the coolest and oldest.

Ice Galaxies continue from my last post. You know me as a night sky photographer who reveals our vast cosmos above, but here you are looking at tiny ice crystals less than 5mm wide, the frost formed on a window glass reflecting the blue sky and sunlight, revealed by a macro lens from inside our house. Photography is not always about traveling. You can also find valuable stories wherever you live, catching the right moment. This was the last day of the polar vortex that caused brutally cold weather in a large area of North America. Enjoy the phone wallpapers on today story ... #icecrystals#macrophotography#whpcolorwheel

These are not stars nor far galaxies! You are looking at tiny ant-size ice crystals on a window glass reflecting the blue sky and sunlight. The largest one is only 5mm wide. Photography is not necessarily about traveling. Sometimes most interesting stories and subjects are just next to you, if you can see them in the right moment. This was the last day of the polar vortex that caused brutally cold weather in a large area of North America. In my usual visit to our baby room suddenly saw the ice crystals on the window. The 105mm Macro lens and the extender revealed magnificent piece of natural art, some of the most beautiful patterns I have seen, just a foot away from the diaper changing table!

Today is the opening of a planetarium show that I collaborated with in the past year for Perlan museum (Wonders of Iceland) @perlanmuseumiceland. If you visit Reykjavik in future this is a must-see place with the best view to the city, an ice tunnel, and the high-end 8K digital planetarium for an immersive experience of northern lights including this scene which I captured in a major aurora storm in March 2015. The music is The Four Season (Vivaldi). #northernlights#auroraborealis#iceland#perlan#reykjavik#fulldome#planetarium#twanight@mtlrealisations@gunnarsprettur@saevarhb@margretth10@ragnarth@snorrithorphotography@twanight

Swipe left for this night panorama of the massive rock formations in the Monument Valley, an icon of the South West on Utah-Arizona border inside the Native American land of Navajo Nation. Stars of constellation Sagittarius and the core of the Galaxy are above this cluster of sandstone buttes reaching about 1,000 ft (300 m) above the valley floor. The second slide shows the Lagoon Nebula, home to newborns stars some 5000 light years away. #saveournightsky#twanight#panorama#astrophotography#monumentvalley@twanight@natgeoimagecollection
