DAKAR, Senegal — When Salma Sylla was just a little lady, she tried to search out reduction from Senegal’s steamy scorching season by retreating to the roof of her residence to sleep. Restless and overheated, she would lie awake staring on the stars.

The space the place she lived outdoors Dakar, the capital, had no electrical energy, and the heavens sparkled. She tried to rely the celebs, realizing extra shone on some nights than on others.

Ms. Sylla, now 37, was intrigued. But finding out the celebs in Senegal was not straightforward: High faculty programs had been restricted; libraries not often had books on house; telescopes had been few and costly.

Not a lot has improved since Ms. Sylla was a woman; astronomy choices are extraordinarily restricted in Senegal’s universities. But officers right here hope to vary that, as a part of a mission to enhance science, expertise, engineering and math expertise by bolstering the nation’s college applications and constructing a science and analysis heart.

“This is the farthest exploration of anything in space that has ever taken place, by quite a lot,” mentioned Alan Stern, challenge chief for NASA’s New Horizons mission. “We are way, way out there.”

For the scientists, coming to Senegal was a technique of elimination. Most of the areas that supplied the very best viewing had been in the course of the Atlantic Ocean. The different choices — in neighboring Mali, for instance — had been in areas patrolled by violent extremists.

The countryside of Senegal is peaceable, elements of it should not have electrical energy, and lots of rural areas are sparsely populated. That was a bonus for the scientists, who needed a transparent sky, free of sunshine. Still, Senegal was a dangerous proposition. The space is on the cusp of the wet season, and cloudy skies threatened to dam the occasion, which occurred early Saturday and lasted lower than a second.

Scientists are nonetheless evaluating information from the viewing, however the skies turned out to be clear and they’re hopeful.

Senegal was an enthusiastic host. About two dozen Senegalese astronomers and scientists, together with Ms. Sylla, accompanied the New Horizons group within the area and contributed to the viewing.

African nations have racked up their very own house achievements. Moroccan astronomers have found comets, asteroids and planets outdoors our photo voltaic system. Ghana’s first satellite tv for pc is now orbiting the earth. Students in Tunisia have organized public occasions to watch the sky, although they don’t have an observatory.

“Astronomy is virtually as popular in Africa as it is everywhere in the world,” mentioned David Baratoux, the president of the African Initiative for Planetary Sciences and Space, who is predicated in France.

The largest hindrance is cash. The United States spends extra on its house program than the worth of Senegal’s total financial system. The 21 high-powered telescopes introduced by the New Horizons group had been practically double the variety of telescopes obtainable in all of Senegal.

The New Horizons group hopes that the telescopes in Senegal and a handful in Colombia, with some help from the Hubble Space Telescope, will reply some questions on Ultima Thule, a part of the Kuiper belt, earlier than its spacecraft arrives. Is it formed like a potato, as an example, or is it truly two objects orbiting one another?

Last week, at a late-night gown rehearsal for Saturday’s viewing, Diarra Dieng, an utilized physics pupil in Dakar, tweaked the settings on a $3,500 telescope, guided by a NASA scientist.

“This is amazing,” she mentioned, as she tried to coach the telescope on the right star.

Instructors at Ms. Dieng’s highschool in Dakar had inspired her to pursue research in science, however she was skeptical at first. “I never knew girls could do this kind of work,” she mentioned.

The New Horizons group had unfold throughout the garden of a convention heart to work out gear kinks forward of the viewing. The largest drawback got here when somebody by accident turned on the sprinkler system.

The scientists let anybody milling in regards to the close by parking zone get a view of Saturn and Mars. Students who had studied astronomy by way of on-line programs joined an extended line. Fathers hoisted young children to the eyepiece. The minister of upper training took a peek.

“Mmmmm,” was all one lady may say, shaking her head as if in disbelief.

The increased training minister, Mary Teuw Niane, mentioned he hoped the group’s go to would foster future pupil collaborations with NASA.
