Stars Over the Empty Quarter

Stars over the desert were the original text, and everything written since was commentary. Aisha did not say this aloud because it sounded like the kind of thing someone would embroider on a cushion, and she was not a cushion person. She was an astronomer, which was a person who looked at the sky for a living, and if that sounded simple it was because the simplicity was a disguise for a problem that had been defeating the best minds in the species for about five thousand years. She was in the Rub' al Khali. The Empty Quarter. Southeastern Saudi Arabia, where the sand went on until it met more sand, and the sky was so dark at night that you could see the Milky Way with the resolution of a photograph. Light pollution was not a concern here. Human presence was barely a concern. The nearest town was two hours by Land Cruiser over a surface that optimistically called itself a road. Her research station was a prefabricated building with a satellite dish, a generator, and a telescope that cost more than the building, the generator, and the dish combined. She shared it with Dr. Hassan, who studied radio astronomy and who communicated primarily through sighs of varying intensity, a language in which he was fluent and which Aisha had learned to interpret over three years of fieldwork. A short sigh meant the equipment was malfunctioning. A long sigh meant the data was inconclusive. A very long sigh meant the generator had failed again. The generator failed every three weeks. This was its schedule. It failed the way weather happened — predictably, inevitably, and with total indifference to the consequences. When it failed, the telescope shut down, the instruments went dark, and Aisha and Hassan sat in the sudden silence and looked at the sky with their eyes, which was how astronomy had started and which was, in certain moments, still the best way to do it. "We should get a new generator," Hassan said. "We should." "I'll write to the university." "You wrote last month." Sigh. Medium length. The university. Aisha studied galaxy formation. Specifically, she studied the light from galaxies that had been travelling toward Earth for billions of years and that arrived at her telescope like a letter from the distant past, written in wavelengths instead of words. The light told her things. How fast the galaxy was moving. What it was made of. How old it was when the light left, which was not how old it was now, because in the time it took the light to arrive, the galaxy had changed, and might not even exist anymore. She was studying ghosts. Beautiful, luminous ghosts made of hydrogen and time. This was difficult to explain at family gatherings. "What do you study?" her aunt asked, every Eid. "Galaxies." "And this is useful?" "It tells us where we come from." "I know where I come from. Makkah." Her aunt was not being dismissive. She was being honest. The value of knowing where galaxies came from was abstract, and her aunt was a concrete woman. She valued children, good food, and the price of gold, in that order. Galaxies did not appear on the list. Aisha did not try to add them. The work happened at night. This was obvious but also defining. Aisha lived nocturnally, sleeping through the desert heat, waking at dusk, working until dawn. She had done this for seven years. Her circadian rhythm had surrendered to the schedule the way her aunt had surrendered to the existence of galaxies — without enthusiasm but without resistance. Some nights the seeing was perfect. The atmosphere still, the air dry, the temperature stable. On those nights, the telescope could resolve details that were invisible from anywhere with streetlights or humidity or civilization. She could see structure in galaxies eleven billion light-years away. Spiral arms. Dust lanes. The architecture of a thing so large that the mind collapsed around it like a lawn chair that someone had sat on wrong. On those nights, she forgot about the generator and the university and the road that wasn't a road. She forgot about the heat she would sleep through tomorrow and the data she would process next week. She was looking at light that had started its journey when the Earth was three billion years old, when life was single-celled and the continents hadn't decided where to go. That light had been travelling while everything happened. While the continents moved. While fish became amphibians became mammals became people who became astronomers who built telescopes in the Empty Quarter to catch the light that had been coming all this time. Aisha recorded it. She measured it. She wrote papers about it that twelve people in the world fully understood, and that her aunt did not read, and that mattered in a way she could not prove but knew. Dawn came. The stars faded. She powered down the telescope and walked outside. The desert was orange and gold and absolutely empty, and above it the sky was shifting from black to blue, and somewhere in the blue, invisible now, the galaxies were still there, sending their light.
