.Thus, her research target was limited to radiation within the frequency ranges monitored by Red Coast during periods of normal solar activity.Research conditions at the base weren’t too bad.The library could obtain foreign-language materials related to the topic, including timely European and American academic journals.In those years, this was no easy feat.Ye also could use the military phone line to connect to the two groups conducting solar science research within the Chinese Academy of Sciences and obtain their observation data by fax.After half a year of study, Ye saw no glimpse of hope.She quickly discovered that within the frequency ranges monitored by Red Coast, solar radiation fluctuated unpredictably.By analyzing large amounts of observed data, Ye discovered a puzzling mystery.Sometimes, during one of the sudden fluctuations in solar radiation, the surface of the sun was calm.Since hundreds of thousands of kilometers of solar material would absorb any shortwave and microwave radiation originating from the core of the sun, the radiation must have come from activities on its surface, so there should have been observable surface activity when these fluctuations occurred.If there were no corresponding surface disturbances, what caused these sudden changes to the narrow frequency ranges? The more she thought about it, the more mysterious it seemed.Eventually Ye ran out of ideas and decided to give up.In her last report, she conceded that she could not solve the problem.This shouldn’t have been a big deal.The military had asked several groups within universities and the Chinese Academy of Sciences to research the same issue, and all of those efforts had failed.But Yang wanted to try one more time, relying on Ye’s extraordinary talent.Lei’s agenda was even simpler: He just wanted Ye’s paper.The research topic was highly theoretical and would show off his expertise and skill.Now that the chaos in society was finally subsiding, the demands on cadres were also changing.There was an acute need for men like him, politically mature and academically accomplished.Of course he would have a bright future.As to whether the problem of interference from solar outages could be solved, he didn’t really care.But in the end, Ye didn’t hand in her report.She thought that if the research project were terminated, the base library would stop receiving foreign language journals and other research materials, and she would no longer have access to such a rich trove of astrophysics references.So she nominally continued her research, while in reality she focused on refining her mathematical model of the sun.One night, Ye was, as usual, the only person in the cold reading room of the base library.On the long table in front of her, a pile of documents and journals were spread open.After completing a set of tedious and cumbersome matrix calculations, she blew on her hands to warm them, and picked up the latest issue of the Journal of Astrophysics to take a break.As she flipped through it, a brief note about Jupiter caught her attention:Last issue, in “A New, Powerful Radiation Source Within the Solar System,” Dr.Harry Peterson of Mount Wilson Observatory published a set of data accidentally obtained while observing Jupiter’s precession on June 12 and July 2, during which strong electromagnetic radiation was detected, lasting 81 seconds and 76 seconds, respectively.The data included the frequency ranges of the radiation as well as other parameters.During the radio outbursts, Peterson also observed certain changes in the Great Red Spot.This discovery drew a lot of interest from planetary scientists.In this issue, G.McKenzie’s article argues that it was a sign of fusion starting within Jupiter’s core.In the next issue we will publish Inoue Kumoseki’s article, which attributes the Jovian radio outbursts to a more complicated mechanism—the movements of internal metallic hydrogen plates—and gives a complete mathematical description.Ye clearly remembered the two dates noted in the paper.During those windows, the Red Coast monitoring system had also received strong interference from solar outages.She checked the operations diary and confirmed her memory.The times were close, but the solar outages had occurred sixteen minutes and forty-two seconds after the arrival of the Jovian radio outbursts on Earth.The sixteen minutes and forty-two seconds are critical! Ye tried to calm her wild heartbeat, and asked the librarian to contact the National Observatory to obtain the ephemeris of the Earth’s and Jupiter’s positions during those two time periods.She drew a big triangle on the blackboard with the sun, the Earth, and Jupiter at the vertices.She marked the distances along the three edges, and wrote down the two arrival times next to the Earth.From the distance between the Earth and Jupiter it was easy to figure out the time it took for the radio outbursts to travel between the two
