Rosetta, mission zero gravity

Rosetta was a European Space Agency mission with the objective of sending a probe on a six-and-a-half billion-kilometre journey to the comet Churyumov–Gerasimenko, an object so small that its gravity is barely perceptible.

To reach its objective, the probe travelled for ten years, taking its momentum from one planet to another and finally reaching Churyumov–Gerasimenko with a speed almost identical to that of the comet. This game of cosmic billiards allowed researchers to observe the comet very closely and even to land a robot on its surface. Mastery of the laws of gravity made this feat possible. It took almost thirty years to settle all the stages and details of this journey, which in the end proved to be a resounding success for European space research. This adventure will be told by one of those who lived it from the inside.

Gravitational Waves and Binary Black Holes
Gravitational waves and black holes are two of the predictions generated by Einstein's theory of general relativity. These appeared as early as 1916, shortly after the publication of the work...
