D07.1.1._Supemova 1987A
SUPERNOVA 1987A
In February 1987, a flash appeared in the southern night sky. Located 168 000 light-years from Earth in a nearby galaxy called the Large Magellanic Cloud, it was the 1987A Supernova. This flash was caused by a massive star ending its life in a spectacular explosion. It was the brightest phenomenon of this nature to be observed in our cosmic vicinity for centuries and was even visible to the naked eye for several months. This observation helped push forward our understanding of the evolution of stars.

D07.2.1._Halley's cubicle
HALLEY’S COMET
For millennia, we have feared comets as objects of destruction, until astronomical observations and celestial mechanics in the 17th century clarified the nature of these cosmic wanderers. In 1986, the Giotto spacecraft flew within 600 kilometers of Comet Halley and revealed for the first time how the nucleus of a comet looks up close: very black due to organic material. Recent research suggests that these icy relics of our Solar System’s formation may have contributed to bringing water and other molecules to our planet, including the building blocks of life.

D07.3.1._Communicating with the public
COMMUNICATING ASTRONOMY WITH THE PUBLIC
01 CARL SAGAN
02 STEPHEN HAWKING
Today, it is hard to imagine astronomical outreach without public lectures, books, TV shows and a multitude of online materials. However, this material was not always so plentiful. It is thanks to the efforts of exceptional scientists around the world who were active as science communicators, such as Carl Sagan and Stephen Hawking, that astronomy and physics reached their current status in modern media and culture. Their seminal works include Sagan’s 1980 book and TV series “Cosmos” and Hawking’s 1988 book, “A Brief History of Time”, which both played a key role in communicating complex topics to the public in an approachable, yet inspiring and entertaining way.
