We bear witness each day to some small celestial wonder never again to be seen by human eyes. The rare meteor—some lost fragment of a comet gone by—coursing through the heavens as a brief and tiny luminescent slice. The pulse and cadence of a distant star's twinkle, as unique as a fingerprint's swirl or the latticework of a snowflake. Those moments and details belong to their witnesses, and to no one else. They will never be seen precisely the same way again. It happens, we watch, and we are moved in some way. We take the event with us when we are gone. It's not often that we share in these events with millions, and rarer still that we know the precise time to take a photograph that will last forever.

The eclipse on August 21 will be one such time. To help you capture the moment with your camera, Mental Floss spoke to Steve Heiner, senior technical manager with Nikon, who saw his first eclipse 38 years ago. Here is what he told us you need to know. 

1. BE IN THE RIGHT PLACE.

Witnessing the eclipse from outside the path of totality is like catching a glimpse of Disneyland from the highway. It's just not the same. Either you are there or you are not. The first step, then, in photographing a total eclipse is getting there. This is not as easy as it sounds, and this late in the game, accommodations are hard to come by—but not impossible. Such large cities along the path as Idaho Falls, St. Louis, Nashville, and Columbia are equipped to handle massive crowds from tourism and conventions. You can still find a room. Moreover, active, retired, and reserve military service members across the country have exclusive access to such major bases along the path as Whiteman Air Force Base, Fort Campbell, and Fort Jackson. So if you really want to be in the path, do not despair, but do not delay.

2. GET A FILTER.

Sure, a few fortunate photographers will walk into the path peeling protective cellophane from the virgin displays of shiny new cameras … but it is not a requirement. If you have any camera at all—including the one on your smartphone—you're practically prepared for the event already. You might want a solid, stable tripod, too, but it is not a requirement. What you will definitely need is a "full aperture solar filter" to cover your camera lens. This will protect the camera's image sensor from being damaged by sunlight during the partial phases of the eclipse. Such filters are not hard to find, though perhaps patronize a reputable retailer. (The eclipse has brought out more than a few hucksters.) Consider also procuring protective eyewear. You will be staring at the Sun, after all, and will presumably want to continue using your eyes the day after the eclipse. Get a few pairs, because according to NASA, you can use the filters from ISO-certified eclipse eyewear as a full aperature solar filter [PDF] on your smartphone. And don't forget to turn off your flash.

3. CHOOSE THE RIGHT LENS.

"If you shoot a picture that excludes everything but the Sun, then it looks like every other picture that you can pull up on the Internet, or that anyone has ever shot of a solar eclipse," Heiner tells Mental Floss. Eclipses happen several times around the world every year. There are enough pictures of a Moon-masked Sun to go around. "I've been encouraging people to try to put the eclipse in context."

To that end, rather than using a telephoto lens trained on the Sun, consider a more moderate or wide-angle lens able to capture not only the eclipse, but also some scenery around you. "As the eclipse approaches totality, turn around 180-degrees and photograph people looking through their solar glasses. It can be almost as interesting a photograph as the Sun itself," he says.

4. REMOVE YOUR FILTER AT THE RIGHT TIME.

"If you're interested in isolating the Sun in the sky and getting nothing but the actual eclipse, obviously it benefits you to be right in the path of totality," says Heiner. "You'll get that distinct corona on the outside as the event is taking place." Heiner recommends keeping the lens filter in place right up to the moment of totality. Then remove the filter from your camera and behold a shimmering, hazy halo of light that seems to reach from the black Moon's horizons. It is safe to photograph this. When the Sun again emerges from the Moon, reattach the filter.

5. CAPTURE YOUR PERSONAL ECLIPSE.

Remember that this is the photography event of the year, and battalions of professionals will be drawn to the path. You probably can't take a better shot than they can. Rather than trying to take an eclipse photograph worthy of the cover of National Geographic, set your sights lower—literally. Everyone will see the Sun, but only you will see the city, park, mountains, or canyons around you. Only you will see the children laughing at the wonder of the moment, the animals scurrying along, the jaded teenagers struck with wonder. "Look around and try to keep your own personal context in mind when you're shooting," says Heiner. "Those are the pictures that, while they can include the eclipse, will also include elements that others will not have access to. It makes the pictures more personal."

He recalls his own experience from an eclipse 38 years ago. "One of the most intriguing things that I remember was that, if you look around under the shade of trees, all that dappled light—which looks quite normal on any other day—will turn to tiny crescents during the eclipse. To me that sort of detail can be as interesting as the actual eclipse itself. I would encourage people not to always be looking straight up at the Sun. Look around. Notice what's going on around you, and all the excitement regarding the eclipse. I think some of those pictures will end up being the ones you really remember."

6. TRUST YOUR CAMERA.

The eclipse will be a very forgiving photography model even for rank beginners. The Sun will be reduced to a very prominent crescent shape as the Moon travels across its face. During that time, it is crucial to have a filter attached to your camera. In addition to protecting its sensor, it will ensure that pretty much the only thing illuminated in the scene is the Sun. Most camera metering systems will factor that in and take fairly decent photographs.

Heiner suggests that amateur photographers consider bracketing their photographs. This basically involves shooting multiple pictures at slightly different exposure settings. The benefit of digital cameras today is that when you shoot a picture, you can review it immediately. If you see a picture you don't like, you can make a fast adjustment to correct the flaw. (Nikon recommends choosing a single aperture and bracketing shots "over a range of shutter speeds from 1/1000 second to 1 second.")

7. BONUS TIP FOR THE ADVANCED AMATEUR: TIMELAPSE 

"Somebody at a high level might consider doing what is known as a timelapse," says Heiner, "when they can set the camera to take pictures automatically at a given interval. With the appropriate filter in place as usual, they can actually shoot photographs unattended through the whole process of the eclipse, and then actually stack them together or assemble them into a single image later, using software." (Nikon provides tutorials on how to do this, and other eclipse photography techniques.)

Regardless of how you record the eclipse, don't forget to experience it not through glass or smartphone screens, but with your own eyes, your own senses. Before hoisting your camera and snapping the Sun, take it all in. Make your memories. See a day turned to darkness, and animals scurrying home to nests and hollows. See the human response, which might perhaps be the most moving. For fleeting moments—a minute or two out of one's entire life—all heads will turn and rise in unison and cast no judgment but wonder. Here we are, on a pale blue dot, sharing in event of our star blotted from the sky. 

Two Harvard Scientists Suggest 'Oumuamua Could Be, Uh, an Alien Probe

An odd, cigar-shaped object has been stumping scientists ever since it zoomed into our solar system last year. Dubbed 'Oumuamua (pronounced oh-MOO-ah-MOO-ah), it was first seen through the Pan-STARRS 1 telescope in Hawaii in October 2017. 'Oumuamua moved at an unusually high speed and in a different kind of orbit than those of comets or asteroids, leading scientists to conclude that it didn't originate in our solar system. It was the first interstellar object to arrive from somewhere else, but its visit was brief. After being spotted over Chile and other locales, 'Oumuamua left last January, leaving lots of questions in its wake.

Now, two researchers at Harvard University bury a surprising suggestion in a new paper that analyzes the object's movement: 'Oumuamua could be an alien probe. Sure, why not?

First, astrophysicists Shmuel Bialy and Abraham Loeb argue that 'Oumuamua is being driven through space by solar radiation pressure, which could explain its uncharacteristic speed. But for that theory to work, they calculate that the object must be unusually thin. Bialy and Loeb then analyze how such a slender object might withstand collisions with dust and gases, and the force of rotation, on its interstellar journey.

Then things get weird.

"A more exotic scenario is that 'Oumuamua may be a fully operational probe sent intentionally to Earth vicinity by an alien civilization," they write [PDF]. They suggest that ‘Oumuamua could be be a lightsail—an artificial object propelled by radiation pressure—which also happens to be the technology that the Breakthrough Starshot initiative, of which Loeb is the advisory committee chair, is trying to send into space. "Considering an artificial origin, one possibility is that 'Oumuamua is a lightsail, floating in interstellar space as a debris from an advanced technological equipment,” they write.

Their paper, which was not peer-reviewed, was posted on the pre-print platform arXiv.

Loeb is well known for theorizing about alien tech. He previously suggested that intense radio signals from 2007 could be the work of aliens who travel through space on solar sails. However, Loeb acknowledged that this theory deals more with possibility than probability, The Washington Post noted. “It’s worth putting ideas out there and letting the data be the judge,” Loeb told the paper last year.

A Team of Young Women Wants to Send Kyrgyzstan's First Satellite to Space

Kyrgyzstan is one of 123 countries that doesn't have a national space agency. That could soon change, thanks to a group of young programmers and engineers taking the matter into their own hands.

As The Next Web reports, the Kyrgyz Space Program is made up of 12 women ranging in age from 17 to 25 years old. They met in 2017, when journalist and TED fellow Bektour Iskender started a free course in his home country of Kyrgyzstan teaching young women there how to build robots and satellites.

The team has since made it its mission to build a cube satellite (CubeSat)—a smaller type of satellite that costs about $150,000 to put together. If they are able to construct the spacecraft, launch it into orbit, and send it to the International Space Station as planned, the project will mark the first time Kyrgyzstan has sent a satellite into space.

The Kyrgyz Space Program now meets twice a week in the offices of Kloop, a media outlet that's known for its support of feminist causes in a country where women still have a long way to go to reach parity. Even as more women start to get involved in Kyrgyzstan's politics, domestic violence, child marriage, and bride kidnappings are still rampant.

In order to accomplish their goal of sending a Kyrgyz satellite to orbit, the program has launched a crowdfunding campaign. Reaching the $2500-a-month marker means they can construct the CubeSat with guidance from the team who launched Lithuania's first satellite. If they reach the $10,000-a-month threshold, they will be able to send the CubeSat to the International Space Station. You can join the 120 people who've already supported their Patreon page by pledging today.
