I just read a high-frequency radio pulse from the direction of the planet!

The scientists were running a continuous research seminar on the nature, origin, and possible significance of the radio pulses.

The astronomers took detailed measurements of the radio pulses that reached Earth.

It was visible all around the Earth and its radio pulses detectable.

The rate of radio pulses, usually three per second, would speed up and then slow down in a cycle that repeated itself every six months.

But other facilities must be picking up die radio pulses.

"I'm not going to put my reputation on the line for some radio pulses and a couple of photos!"

No more radio pulses, and our alien visitor is leaving us.

Schmidt may have discovered the radio pulses, but I am going to be the first man to make actual contact with that alien.

You can see the exact pattern in the radio pulses, right below them.
