    Surprise! High School Student Discovers New Planet Three Days Into NASA.

When 17-year-old Wolf Cukier accepted an internship (实习) at NASA, he expected to be challenged and gain insights into pursuing a career in astrophysics (天体物理学) . Instead, he attained worldwide fame for an achievement finding a new planet!

The teenager came across the distant world while examining images of the variations in star brightness captured by NASA's Transiting Exoplanet Survey Satellite (TESS) and uploaded to Planet Hunters TESS by amateur citizen astronomers. “I was looking through the data for everything the volunteers had marked,” Cukier said. “About three days into my internship, I saw a signal from a system called TOI 1338. At first, I thought it was a stellar eclipse (日食) but the timing was wrong. It turned out to be a planet.” Further research revealed that TOI 1338 b, as it is now called, is a rare circumbinary planet (环双星行星) — a world orbiting two stars. Even more exciting, TOI 1338 b is the first circumbinary world discovered by the TESS mission.

The researchers believe that TOI 1338 b is about 6.9 times larger than Earth. The experts claim that TOI 1338 b's two stars vary in size. It is also the only planet in the TOI 1338 system, which lies 1,300 light-years away from Earth.

Not surprisingly, the High School senior is looking to pursue a career in physics and astrophysics. When asked of his plans to seek out a job at NASA, the youngster said, “I've no idea about NASA's hiring practices but it can't hurt!” He added, “A career in space research is appealing.”
