The data arrived on a Tuesday in March, in the form of a printed strip of paper no wider than a business card. Dr. Whitaker placed it on Eleanor's desk at the Harriman Observatory, smoothed it with his thumb, and said nothing. The observatory dome was warm — the heating system, installed in 1919 and never properly maintained, rattled like an asthmatic man — and the smell of machine oil and old paper hung in the air.

Eleanor read the strip. She read it twice. She read it a third time, with her fingers pressed to her mouth, as though holding it there might prevent the numbers from escaping.

'Dr. Whitaker,' she said. 'This cannot be right.'

'You calibrated the instruments?'

'Three times. I calibrated them myself.'

'Then it is right.'

She looked up at him. Dr. Whitaker was seventy-two, with a face like a retired boxer — all knuckles and scars — and eyes that had spent fifty years looking at things too bright and too distant for human retinas. He did not flinch.

'How long?' she asked.

'Until heat death? The models suggest approximately twenty-two billion years, give or take a factor of two. But that is not what the strip says. The strip says the expansion is accelerating faster than any model predicted. Significantly faster. We are looking at a timeline of approximately...' He paused, consulted a calculator that sat on his desk like a brass beetle. 'Two hundred million years.'

Eleanor felt the room tilt. Not literally — the observatory was bolted to bedrock — but something in her vestibular system gave a small, private lurch, as though the floor beneath her shoes had moved half an inch to the left.

Two hundred million years. In cosmic terms, this was nothing. A heartbeat. A blink. A woman standing at a mirror and noticing, for the first time, that her reflection is slightly flatter than she expected.

'The universe,' she said, and her voice sounded strange to her ears, as though it belonged to someone else, 'is going to die in two hundred million years.'

'That is what the data says.'

'That is —' She stopped. She had spent eleven years at Harriman Observatory — eleven years of night shifts, of cold coffee, of adjusting lenses and recording spectra and pretending that the enormity of what she was studying was something she had made peace with. But knowing and understanding are not the same thing. Knowing is a fact you can file away. Understanding is a fact that files you.

'Can we slow it down?' she asked.

Dr. Whitaker looked at her over his spectacles. 'Can we slow it down? No. Can we stop it? No. Can we reverse it? No.'

'Can we record it?'

He considered this. 'Record what?'

'Everything. Everything that we are. Everything that we have been. If the universe is going to end —' She gestured at the data strip, at the sky above the dome, at the city of New York glowing amber and white beyond the observatory's hilltop perch — 'if all of this is going to end, then something should know that it happened. Something should remember us.'

Dr. Whitaker took off his spectacles and cleaned them slowly, methodically, with the corner of his handkerchief. When he put them back on, his eyes were redder than usual.

'Eleanor,' he said. 'What are you proposing?'

She had been proposing it to herself for three hours, since Dr. Whitaker first brought her the strip. She had paced her small apartment in Morningside Heights, walked the length of Central Park, sat on a bench in the rain and watched the fountains freeze mid-plume. She had proposed it to herself with the quiet desperation of a woman who knows her proposal will be heard and ignored.

'A transmission,' she said. 'Focused electromagnetic pulses, aimed at thousands of star systems. Each pulse will encode — not data, exactly. Not numbers and equations. But the things that make us us. The music. The paintings. The letters people wrote to each other. The grocery lists. The things we did not think were important, which were the most important things of all.'

'You want to send a library to the stars.'

'A library that will outlast us. If the universe has two hundred million years left, a signal traveling at light speed could reach thousands of star systems. Someone, somewhere, might receive it. Might understand it. Might know that we were here.'

Dr. Whitaker was silent for a long time. The observatory heated system rattled. Somewhere in the building, a phone rang once and stopped.

'You will need funding,' he said at last.

'Yes.'

'You will need technology we do not yet possess.'

'Yes.'

'You will need permission from people who do not understand why you are asking for it.'

'Yes.'

'And you will never see the signals arrive.'

Eleanor looked out the window at the stars. They were invisible in the daylight, but she could feel them — two hundred million years of darkness between them and her, a gulf so vast that thinking about it made her teeth ache.

'I know,' she said.

Julian Morrison came to the observatory the following week. He was deaf — born that way, he told her, though he never spoke of the feelings this gave rise to in him, and she never asked — and he communicated through a combination of speechreading and a notepad he carried in his breast pocket. He was a painter, which seemed an unlikely profession for a man who could not hear the sound of his own brushes on canvas, but Eleanor had seen his work and understood that hearing was irrelevant.

She explained her project to him in fragments — words she shaped carefully, watching his face, pausing between each sentence to let him read her lips. He listened with an intensity that made her feel as though he were not just hearing her words but listening to the spaces between them.

When she finished, he picked up his notepad and wrote, slowly, deliberately:

This is the most beautiful thing I have ever heard.

He painted for her the next three months. He created compositions that translated human emotion into visual form — grief as a deep indigo with jagged edges, joy as a golden light that seemed to vibrate on the canvas, love as a colour that had no name and existed between colours, the way Arthur Pendleton's colours had existed between the colours Eleanor knew.

Senator Harriman called her to Washington in June. The hearing room was large and wood-paneled, with portraits of dead men on the walls and a smell of floor wax and old tobacco. Harriman himself sat at the centre of a long table, a powerful man in a dark suit with a face like a bulldog — not ugly, but not handsome, the face of a man who had spent fifty years saying no and had become accustomed to getting his way.

'Ms. Starkhorn,' he said. 'You are asking the United States Congress to fund a project that will — you estimate — cost approximately three million dollars over the next decade. A project whose scientific value is zero, whose practical applications are zero, whose very purpose is — to send postcards to nobody.'

'Not postcards, Senator. A record. A —'

'A library. Yes. To whom? To whom exactly are you sending this library?'

'To anyone who might be listening.'

'There is nobody listening, Ms. Starkhorn. The universe is empty. It always has been. You are spending American tax dollars on a fantasy.'

She looked at him — this bulldog of a man, born in 1860 in Ohio, who had worked his way up from newspaper editor to United States Senator through a combination of ambition, ruthlessness, and an uncanny ability to know which side of every issue was the winning side. He was not wrong. He was not right. He was simply a man in a room, saying no to a woman who was asking him to imagine something larger than the room.

'I am not asking you to believe in fantasy, Senator,' she said. 'I am asking you to fund a project that records who we are. Not for the aliens. For us. For the simple fact that we existed, at all.'

Harriman leaned back. He tapped his pen on the table. He looked at the other men at the table — six of them, all of them born before 1870, all of them accustomed to saying yes and no according to a timetable that had nothing to do with the stars.

'We will —' he began, and then stopped. He looked at Eleanor, really looked at her, for the first time. His eyes were grey and small and without warmth.

'Ms. Starkhorn,' he said. 'You are a brave woman. Bravery is not, however, a line item in the federal budget. This project is denied.'

He smiled. It was not a kind smile. 'But I will tell you what: I know a private donor who might find your project charming. Mr. Rockefeller, perhaps. He has a fondness for —' He searched for the word. '— noble failures.'

The first transmission launched on a clear night in November, two years after Dr. Whitaker brought her the strip. Eleanor stood in the observatory control room, watching the dials and gauges and switches, her hand on the button that would activate the transmitter. Julian stood beside her, his face turned toward the dome, his mouth slightly open in the expression he always wore when he was 'listening' with his eyes.

'Are you ready?' Dr. Whitaker asked from the doorway.

Eleanor looked at the button. She thought of the two hundred million years. She thought of Julian's paintings, encoded into electromagnetic pulses. She thought of grocery lists and love letters and lullabies and the sound of rain on a tin roof.

She pressed the button.

The dials jumped. The gauges flickered. The transmitter hummed, a sound so low that Eleanor felt it in her chest rather than heard it, and the first pulse of the Interstellar Library rose from the Harriman Observatory and climbed through the atmosphere and into the dark between the stars, carrying with it the memory of a species that had existed, briefly and beautifully, on a small planet orbiting an ordinary star.

Julian took her hand. His fingers were warm. Eleanor felt the warmth like a question.

She did not answer. She was watching the stars.
