Have you seen the very bright star within the constellation Gemini in the evening skies lately? That is, in fact, no star at all! It's the king of the planets, the biggest and largest: Jupiter. Jupiter is more massive than all the other planets combined. The light we see coming from it is actually sunlight, reflected of its large surface. Due to its relative proximity, compared to stars in the night sky, it appears very bright. Easily spotable with the naked eye and beautiful to behold in even small telescopes. The stripes, the red spot, its four large Galilean moons, ... The king knows how to present himself in the most spectacular of ways.

Wo stellt man im All am besten sein Teleskop ab? Am besten eignen sich da einige der Lagrange Punkte, zum Beispiel der L1 oder der L2. Am L2 steht bereits schon das berühmte James Webb Teleskop. Aber, wieso eigentlich? Diese Punkte sind ziemlich weit weg von der Erde, mindestens 1,5 Millionen km. Das ist weit hinter der Mondbahn!

Wenn etwas schief geht, wenn das Teleskop Reparaturen braucht, dann kann man dort nicht einfach mit Astronauten hinfliegen und mit einem Außeneinsatz alles retten, wie damals beim Hubble Teleskop. Das befindet sich nämlich nur im niedrigen Erdorbit. Wieso stellen wir also trotzdem unsere Satelliten und Teleskope an diesen Lagrange Punkten ab? Und wieso gibt es auf den Lagrange Punkten L4 und L5 zwar keine künstlichen, dafür aber ganze Familien natürlicher Satelliten? Und was hat es mit dem ominösen L3 und der Gegenerde auf sich?

The last human left the lunar surface in December of 1972. Ever since then, we have not set foot on our little companion, even though the path had been built.

Now, over fifty years later, we're going back. NASA is set to launch Artemis II. A mission, which will circle the moon with astronauts on board. For the longest time, human beings haven't left the lower Earth orbit. With all this valid excitement, there also are some very valid questions: why are we going to the moon, when we've already been there? Why not Mars? How are we going back? What comes next? And will we go there to eventually truly stay?

Paul answers these questions for you and will give you lunar fever!
