1 . Surprised scientists say they now have absolute proof that life exists on Jupiter (木星). They’re receiving SOS signals radioed from the destroyed planet! Off the record, NASA higher-ups are analyzing that the signals were caused by the recent strike of Jupiter by comet fragments (彗星碎片).

“Theses signals can only be coming from an intelligent (智慧的) life form,” says Dr. Lucas Mirsch, a highly respected planetary astronomer with close ties to NASA. “Contrary to what we’ve believed for years, we’re not alone in the solar system. And based on what we can tell from the mathematical pattern of these signals, the residents of the largest planet in our galaxy are asking Earth for help.” Dr. Mirsch says NASA officials have absolutely confirmed that Jupiter is the source of the strange signals, which began in late June—just weeks before the comet fragments began to hit the giant planet.

“NASA has investigated every possibility that this could be a hoax,” says Dr. Mirsch. That is, it may be a trick. “State-of-the-art sensors have traced the point of origin to the exact position of Jupiter’s orbit. There’s simply nowhere else they could be coming from.”

One of the specialists who has analyzed the mathematical pattern of the sounds says he and his staff are 99 percent sure the message is an SOS of some sort. “It’s difficult to explain to the public,” said the expert. “But the frequency with which certain numbers occur in a coded message gives us clues about its general content. Although we can’t give an exact word- for-word translation, we can say with reasonable certainty that life-and-death urgency is being communicated.”

NASA won’t officially comment but Dr. Mirsch says, “There’s not much the agency can do to help. All we can do now is pray that Jupiter survives this terrible strike and that our two worlds can make contact again soon.”
