"Yeah, yeah."
"If you're right, we're in big trouble."
"I know, I know," BG panted. "The permits. I never did get around to filling out all those forms."
"Well, there's that, but I was thinking about something a little more serious."
"Like what?"
"Like that aurora. The Crab is an intense X-ray source and we're right in the middle of it. There's too much high-energy stuff hitting our upper atmosphere. Thousands of times more than we usually get. It's not good. All those particles-- millions of times more-will give us a big dose of radiation. It's sensational, but we really should be getting back.."
"Okay, okay. Let me type in the coordinates to reverse our trajectory...there."
Another violent shudder knocked Henrietta to the floor. As she got up the view had definitely changed, but not for the better.
"Uh, oh."
"What happened BG."
"We are now only about 200 million miles from the pulsar. Something must be wrong with my program. I guess I'll have to debug it."
The Crab neutron star, or pulsar, was blazing away at 10 times the brightness of the noonday Sun. Henrietta knew that they would get a lethal dose of radiation in a few hours, and that the Earth's
atmosphere would soon evaporate under the intense X-ray and gamma ray fluxes. Incredible lightning bolts due to the voltages from the low frequency pulsar radiation were striking all around, setting off deafening thunderclaps.
"I'll try again," BG said diffidently.
"Wait," Henrietta demanded. "I think you've got the wrong metric! Type in this command!"
"Okay, okay."
"Alpha 0532, dec 22.01, G mu nu = Inv G 1."
"Got it. Here goes nothing!"
Another violent shudder, and...the sky was dark again. The lights on the Tobin Bridge winked through an incoming fog to the northwest. They were back home in the solar system!
Henrietta said goodbye to BG, who said he had some forms to fill out. She slumped down in front of the monitor. The time clock indicated that it was 2:23:11 a.m.
Dan, the SOT team leader, came by to check with her before going home. He looked at the softly glowing X-ray image of the Crab.
"Beautiful isn't it?" he said.
"Yeah, but I sure wouldn't want to live there," Henrietta said.
"What?"
"Oh never mind. Just dreaming."
