James-Webb-Weltraumteleskop

Das James-Webb-Weltraumteleskop (JWST) ist das leistungsstärkste Observatorium der Menschheit und sieht das Universum im Infrarotlicht. Man kann es sich als „Super-Augen“ vorstellen, die viel weiter und klarer sehen als das Hubble-Teleskop. Sein 6,5 Meter breiter Spiegel aus 18 Sechsecken ähnelt einer Honigwabe. Um kühl zu bleiben, wird es durch einen Sonnenschutz von der Größe eines Tennisplatzes geschützt. Das JWST umkreist nicht die Erde wie der Mond, sondern befindet sich 1,5 Millionen Kilometer entfernt am Punkt L2, um die Entstehung der ersten Sterne und Galaxien zu beobachten.

The physical shape of a giant planet orbiting close to its star offers a unique window into its internal composition. Intense gravitational pull from the host star stretches these planets, causing measurable deformations. These distortions are calculated using a value called the fluid Love number, which describes how a planet responds to external gravitational stress. By measuring this number, researchers can better understand how matter is distributed deep within a planet and test different mod...
