The Planetarium Projected a Star Missing From the Sky

We were hosting a late showing for twenty-three adults and two children. Mara, the presenter, had reached the part where she dimmed the city lights and let the audience imagine a sky without streetlamps. I sat in the projection booth, logging lamp temperature. A sharp white point appeared just above the western horizon on the dome, between two familiar stars.

Mara paused. She knew that stretch of sky as well as I did. She moved the projector forward one hour, then a day, then a century. The stars wheeled across the dome. The extra one stayed fixed above Seat F12.

The boy in that seat pointed at it. When Mara brought up the room lights, his arm remained raised.

His father nudged him. The boy did not blink. The stars disappeared under the brighter lamps, except for the new one, which now looked less like light than a puncture through the ceiling into noon.

I shut off the projector's main breaker. Its cooling fan stopped. The point remained.

I went to the roof access with my phone's sky map. The real sky was clear. Where the program identified a modest blue star, I saw a dark notch among the others. It was not cloud. The stars behind the notch vanished when I shifted my head, as if a thumb were resting against the far side of the night.

When I returned, all twenty-five visitors were still in their seats. Mara said the boy had lowered his arm after I left, but only when someone else pointed. Now three adults were staring upward with their hands raised. One woman whispered that she could see someone looking back.

We began ushering people toward the exits. The doors opened, but nobody crossed them. Visitors walked to the threshold, turned without seeming to choose to, and returned to a different seat. Each move left a tiny spot of white light hovering where their head had been.

Soon five points floated below the dome.

Mara kept a paper seating chart. We marked the five seats and compared their positions to the new points. They formed the beginning of a shape I knew from the old machine's maintenance manual: a six-point alignment pattern used to calibrate the optical head. The sixth point should have been in the projection booth.

My chair was directly under it.

At 9:24, the booth window fogged from the audience side. A fingertip drew a circle in the mist. Then another circle inside it. The glass was three stories above the floor. No one stood near it.

I tried the emergency announcement system. My voice came back through the speakers a fraction of a second before I spoke. It said, Please remain seated while we find your position.

Mara cut the amplifier. The announcement finished anyway in a voice that sounded like mine after years without sleep.

The audience was calm. That made everything worse. They shifted seats quietly, following lines only they could see. A woman in a red coat moved across three rows and sat beneath a new light. Her shadow stayed behind in the old seat, darkening its upholstery. The boy from F12 had gone still again. His father lifted him and found he weighed almost nothing.

I took the manual crank from the storage closet. Our dome has a central maintenance hatch above the projector, hidden behind the projection surface. If something had pierced the ceiling, I needed to know whether it was a physical hole. I climbed the narrow service ladder while Mara tried to keep people away from the marked seats.

Above the dome, there was no daylight, no puncture, and no roof. The service space should have been four feet high. Instead it extended into blackness. A cold air current carried the smell of dust and extinguished matches. Below my feet, the dome looked transparent from above. I could see every seated person as a small warm shape.

Beyond them lay another audience, arranged upside down.

Their seats clung to the underside of a second dome far below ours. They were pale silhouettes with their faces tilted toward me. At the center of that theater stood a projector shaped like ours, except its optical head was made of a human skull. A bright point burned in one eye socket.

I dropped the hatch. From inside the theater, a sound rose like hundreds of people inhaling at once.

Mara met me at the ladder. She had found a note inside a 1978 maintenance binder, tucked behind the calibration diagram. It was written by the planetarium's first projectionist, who had disappeared during an overnight show. The note said: NEVER ALIGN A STAR THAT DOES NOT MOVE. IT IS NOT FAR AWAY. IT IS WAITING FOR ENOUGH OBSERVERS TO GIVE IT A PLACE.

The alignment pattern was almost complete. All six points glowed. The woman in the red coat smiled at nothing, while her shadow stood upright behind her. The boy's father was turning translucent at the fingertips.

Mara decided to break the pattern. She pulled the fire alarm and ordered the audience to stand. Some did. The white points pulled at them like taut threads. One man rose halfway, then snapped back into his seat so hard the frame cracked. The point above him grew larger.

I remembered that alignment is measured from one fixed reference, the projector itself. We could not move the star. We could move the theater's center.

Our optical machine weighed nearly a ton, but its pedestal rested on a rotating platform. Mara and I released the service brake and turned the handwheel. The projector shifted a few degrees. The points of light below the dome drifted sideways. People staggered as the lines holding them changed direction.

The new star did not move.

We kept turning. The dome's projected sky spun while the white puncture remained above Seat F12. The five lesser points dragged through the air, crossing walls and faces. A black seam opened along the western edge of the theater. Through it I saw the other audience rise in unison. Their mouths opened into small circles of white.

Mara shouted that we had to stop. I saw the boy's raised arm begin to bend backward. I pushed the wheel the other way. For an instant the six lights fell into a straight line across the dome.

Then I switched on the work lights.

The points went out. Every person in the theater fell from their seat as if released from a height. The seam closed. The boy cried, loudly and wonderfully, while his father held him. The red-coated woman's shadow returned to her feet. Outside, the blue star was back where the sky map said it belonged.

We canceled the show and filed an electrical incident report. Nobody believed the roof space had changed, and nobody wanted to check it. A contractor inspected the dome the next morning. He found six scorched circles on the projection surface and a seventh on the underside of my booth chair.

Mara resigned a week later. She had begun seeing the extra point whenever she closed her eyes. I stayed to dismantle the optical machine. Its plates were unaltered. We packed each one in foam and sent them to storage.

The night before the truck arrived, I compared the audience's ticket purchases against the security footage. Twenty-five people had entered. Twenty-six walked out.

The extra person never occupied a seat. On every camera, it stood at the back of the theater where the exit should have been, facing the audience. The footage could not resolve its face. Its head was a perfectly round patch of daylight.

I checked the previous year's shows. It appeared in one frame of each, farther away at first, then closer. Nobody had noticed because the projectionist always counted seats, never exits.

The theater is closed now. The city says repairs will take months. I have been going there after dark to check the roof, but the service hatch is welded shut from our side.

Last night I looked up from the parking lot. Every star was in place except the blue one. A small white point shone through the locked entrance instead. When I stepped sideways, it stayed fixed above my head.

I drove home without looking in the mirror. This morning there was a scorched circle on the ceiling over my bed. By noon, five smaller circles had appeared around the room.

The stars need an observer to know where they are. I have closed the curtains, but I can hear chairs shifting in the apartment below. There is no apartment below mine.
