CNN -- A British student says he's cracked a 19 quadrillion-digit long code that's been puzzling Nasa scientists for decades. Nasa have invited him to present his reach at a scientific conference in China.
19,342, 813,113,834,066,795,298,816: The number of digits in the code that student Cen Jung Tjhai says he's cracked. The code is used to evaluate photographic data beamed back from satellites in space.
1,500: The number of university computers Tjhai used to crack the code.
27: Tjhai isa youthful 27 and a PhD student at the University of Plymouth, southern England.
35 mm: The first picture of space was taken on an Ansco Autoset 35 mm camera by U.S. astronaut John Glenn.
1920: The year Edwin Hubble trained his telescope onto the cosmos.
1990: The year the Hubble Space Telescope was launched into space aboard the space shuttle Discovery.
569 kilometers: The height above the earth at which the Hubble telescope orbits.
97 minutes: The amount of time it takes for the Hubble telescope to orbit earth while taking images of space.
Coming into focus. The 19quadrillion code is used to make photographic data sent back from space clearer.
