Note: This story is inspired by an episode of an old animated science fiction TV show, and by an even older myth.
***
The starship received a radio transmission from an unknown source. Communications Officer Jones listened to the signal through his headphones, trying to make sense out of the gentle humming sound, which appeared first louder in his left ear, and then louder in his right. The noise pinged back and forth between his ears, and filled up his brain. It was almost musical, but with strange whispering undertones that almost sounded like words. For a few minutes he just sat there and listened, not even trying to decode it. Finally, he remembered to run the signal through several translators and decoders, but to no avail. The pleasant audio feed was no language the starship computer had ever encountered before.
Officer Jones felt distinctly sure that he should have notified the captain of the signal as soon as it was received. But he was enjoying the signal. He didn't want to share it. He wanted to understand it, and be close to it. Finally he said something.
"Captain, we've received a strange transmission."
Captain Riley hardly turned in his chair. "Run it through the standard decryption modules, and check the radio waveforms for extra-universal transmission types."
"Already done." responded Jones. Impulsively, he said "Captain, you need to hear this. Radio transmission to bridge-wide speaker."
The Captain didn't get a chance to voice his objection before the strange alien musical humming and static filled the air of the room. None of the officers on the bridge immediately responded to Jones's unusual behavior. They all sat still, listening intently, trying to understand the sound they were hearing.
Officer Jones felt completely calm. He felt he was beginning to understand the sound, though words were no clearer. It was like it was whispering to him, drawing him in. Listening to it made him feel relaxed and comfortable, receptive. He never wanted to stop listening to the sound. The sound made him want to obey. The sound made him want to find its source.
Captain Riley also smiled. He did not feel worried about the sound. He was going to understand where the sound came from. He was going to find the source of the sound. He needed to find it. After a few long, heavy moments, the Captain asked: "Officer Jones, are you able to at least locate the source of the transmission?"
Jones answered "Yes Sir. It's coming from a small oxygen-rich planet in the Lorelei star system fifteen lightyears east. That planet is probing our ship now."
Usually a probe would be cause for concern. The ship would ordinarily try to investigate in turn. But the Captain didn't much feel like it.
"Set a course for Lorelei," said the Captain, "We will have to investigate this phenomenon personally."
The men on the bridge listened carefully to the subtle transmission. They relaxed, and settled into their chairs. The right thing to do was to go to the planet. That's was what the ship was for.

It was an hour at most before the ship reached its destination, a beautiful blue and green planet which didn't look very different from earth. As the ship approached the planet, the signal from the planet became stronger and louder on the bridge - it was almost like singing. The men on the bridge were enraptured. They never turned it off. No one suggested it. It didn't feel right.
Captain Riley, Officer Jones, and two other men agreed to teleport to the planet's surface immediately. It was imperative that they understand where the signal was coming from. They had arrived there to understand the signal. The men were there for the signal.
The landing party arrived on the planet's surface in front of a towering acropolis of marble columns. On long wide steps before the columns stood four women, each one tall, blond, and unspeakably beautiful.
Captain Riley spoke: "We are humans, of the planet Earth. We come in peace. We received a foreign signal emanating from this location, and we've come to investigate. Was your planet attempting to contact us?"
A woman in the middle spoke: "I know who you are. I am Tomyris, Queen of the planet Lorelei. You are welcome here."
The Captain started to respond, but before he could get a sentence out, one of the Queen's companions sharply cut him off:
"It is customary for foreigners to bow when they are addressed by the Queen. Bow, Captain."
To bow before anyone was not Captain Riley's custom. He was a captain. But despite himself, Riley felt a shiver run across his spine. He was oddly tempted to comply. The Queen stood so tall on the steps above him. He felt confused. He wasn't sure what to do. For some reason, the thrum of the signal was still playing loudly in his ears, though he was far from his ship.
"You heard my servant," said the Queen, "Bow."
Captain Riley complied. He bent at the waist, a deep bow which he ordinarily would not even have afforded to his highest commanding admiral. He felt pleased with the gesture. The music thrummed in his ears, rewarding him. The Queen would be pleased with him.
