ORIGIN OF THE ELEMENTS AND THE LIFE-CYCLE OF STARS
In the 1950s, scientists realized that stars do not shine forever, but that mass determines their evolution and how they die. Once they exhaust their nuclear fuel of hydrogen, intermediate and massive stars start fusing helium into carbon. Massive stars continue to fuse carbon and heavier elements until they die in a spectacular explosion, a supernova. During the explosion, elements heavier than iron are created and are spread throughout the cosmos.

SPUTNIK 4 OCTOBER 1957
The Soviet Union launched the Sputnik 1 satellite from the Baikonur Cosmodrome into an elliptical low-Earth orbit on 4 October 1957. The world's first artificial satellite was a 58-cm diameter polished metal sphere weighing 83 kg and could complete one orbit around the Earth in 98 minutes. Sending the first human-made object into orbit started the era of space exploration. This became a time of pioneering efforts to launch artificial satellites and space probes, and set forth the pursuit of human spaceflight beyond the realm of Earth’s gravity.This symbolic achievement kickstarted the space astronomy era.

ALBERT EINSTEIN IN POP CULTURE
It is challenging to imagine a personality as iconic as 20th-century physicist Albert Einstein. His special and general theories of relativity are at the foundation of modern cosmology, representing the best framework to date that explains the dynamics and the structure of the Universe. While initially received with skepticism and controversy, his work has since reached worldwide success that established him as a cultural symbol. From art, movies, theatre, gaming and merchandise, Einstein has become a superstar widely featured in products that popularise complex scientific ideas to the public.
