who, what, where, when and for whom

How the first stars were born

We all have heard of the Big Bang and we all have seen the famous image of the cosmic microwave background - the first concrete evidence to support the Big Bang theory. But, how many of us have seen how the universe looked like while it gave birth to the first stars and galaxies? Well, not many... And it's not because we have somehow missed it on the popular science channel. In fact, astronomers themselves hypothesize about the processes that led to the formation of the first bright objects in the skies, but so far the evidence has remained elusive. So they keep searching with ever bigger and more powerful radio telescopes. The heart of LOFAR, currently the largest one in the world is right in your back yard, its antennas sprinkled around Exloo in the province of Drenthe. During the first part of the program, we will travel back in time and show you a simulation of how the Universe evolved when the first stars appeared. We will also let you 'wear LOFAR glasses' and observed other wonders in the radio universe. But this is just the beginning....

How we catalogue the Universe

The first stars, pioneers of the dark universe kept shining, growing, exploding and giving birth to new stars, which gravity slowly brought together to form galaxies. In our explanding universe, this cycle has continued for over 13 billion years giving rise to an unimaginable number of stars, galaxies, dust clouds, solar systems, dying stars, habitable planets and everything else. Its vastness and diversity intimidate and excite us at the same time and we keep looking up, recording, analyzing, understanding... First we only had our naked eyes. Today we use exteremely sophisticated telescopes which we build in high and dry mountains or launch into space. Join us on a short trip to the high mountains of Chile to learn how modern telescopes and the recent technological revolution in data recording and storage help us catalogue more and larger parts of the universe. The more we catalogue, the more we understand. But are we really seeing everything...?

How to find what we cannot see

Well, it turns out we can see just a tiny 4% of what is out there! The rest of the stuff remains invisible to our eyes and instruments. Scientists conviniently call it dark matter and dark energy, but really, it doesn't matter what we call it. What matters is that we are confronted with a mystery of grand proportions and driven by our human spirit of exploration we device grand ideas to solve it. One, among many is the new Euclid mission of the European Space Agency. The Euclid satellite will carry advanced instruments that cannot detect dark matter directly, but can look for its influence on the visible stars and galaxies in the universe. During its expected 7-year flight in space, Euclid will map more than a billion of them, storing the information in trillions of bits. These bits will bring some answers, as well as generate new questions. We may close a chapter, but at the same time we will open a new one to continue reading our cosmic history, bit by bit.
