2/ Warum ist das wichtig? 🚀 Mit diesen Simulationen können wir Vorstellungen über das Wachstum von Galaxien, dunkle Materie und dunkle Energie testen – noch bevor die tatsächlichen Daten von Euclid vorliegen. Dieses Video 👀 vermittelt einen Überblick. #Euclid

1/ Das #Euclid​-Team hat das bislang größte virtuelle Universum mit 3,4 Milliarden simulierten Galaxien veröffentlicht. Es veranschaulicht, was #ESA​s Euclid beim Kartieren des Kosmos sieht.

Bild aus dem Simulationskatalog des Euclid-Flagship-Projekts. Jeder Punkt steht für eine Galaxie: Blaue Punkte markieren Galaxien im Zentrum von Dunkler-Materie-Klumpen, während rote Punkte Satelliten innerhalb dieser Klumpen bezeichnen. Zusammen bilden sie die großräumige Massenverteilung des Universums und bilden Klumpen, Filamente und Hohlräume.

2/ Why does this matter? 🚀 These simulations let us test ideas about galaxy growth, dark matter & dark energy — even before Euclid’s real data arrives. A huge step toward understanding our Universe. Watch 👀 this video for an overview. #Euclid

1/ 🔭 The #Euclid Consortium just released the largest virtual Universe ever built, comprising 3.4 billion galaxies. It shows what @esa.int's Euclid will see as it maps the cosmos. 🌌✨

The project was led by @ice-csic.bsky.social and Port d'Informació Científica.
Image extracted from the Euclid Flagship simulations catalogue. Each dot represents a galaxy: blue points mark galaxies at the centers of dark matter clumps, while red points denote satellites within them. Collectively, they trace the large-scale mass distribution of the Universe, forming clumps, filaments, and voids.

2/ Kommt vorbei im EG des Ministeriums #BMFTR. Unser tolles Team beantwortet alle eure Fragen. Ihr könnt virtuell das #ELT erkunden, mit dem #Glücksrad nach lebensfreundlichen Planeten 🪐 suchen und euch vor dem ELT ablichten lassen. Ein detaillierter 3D-Druck und ein Video zeigen euch alle Details.
Vier Personen posieren neben einer großen Stellwand mit einem Bild des Extremely Large Telescope (ELT), dem im Bau befindlichen Riesenteleskop der Europäischen Südsternwarte ESO. Die Stellwand zeigt den Kuppelbau des ELT auf dem Cerro Armazones in Chile bei Nacht. Aus der Kuppel schießen vier helle gelb-orange Laserstrahlen in den Sternenhimmel, die das adaptive Optiksystem symbolisieren. Links der Stellwand stehen zwei Personen, rechts ebenfalls zwei. Alle lächeln in die Kamera. Die Menschen tragen Freizeitkleidung in Blau, Rot, Schwarz und Weiß. Oben links auf der Stellwand ist das Logo der ESO mit dem Schriftzug „ELT“ zu sehen. Unten rechts stehen die Logos der beteiligten Partnerinstitute, darunter das Max-Planck-Institut für extraterrestrische Physik (MPE). Im Hintergrund erkennt man den Eingangsbereich des Bundesministeriums für Bildung und Forschung mit Glasfronten, Paletten und weiterem Messematerial. Das Foto zeigt den Aufbau des Informationsstands von MPIA und MPE zum ELT beim Tag der offenen Tür der Bundesregierung.

1/ Alles bereit für den Tag der offenen Tür 🚪 #TdoT25 der #Bundesregierung im #BMFTR am 23. und 24. August. Im Auftrag der @eso.org präsentieren #MPIA und @mpe-garching.bsky.social der @maxplanck.de das Extremely Large Telescope #ELT 🔭. #Astronomie #Weltraum #ESO 🌌
Ein fertiger Informationsstand zum Extremely Large Telescope (ELT) im Eingangsbereich des Bundesministeriums für Bildung und Forschung. Der Stand präsentiert sich mit mehreren Elementen: Im Vordergrund ein Tisch mit ausliegenden Informationsmaterialien, darunter Flyer und Bildkarten astronomischer Motive. Auf dem Tisch steht eine große durchsichtige Vitrine mit einem maßstabsgetreuen Modell des ELT. Dahinter hängen Stellwände mit einem nächtlichen Bild des Teleskops und leuchtenden Laserstrahlen. Zwei große Bildschirme links und rechts des Modells zeigen Animationen und Fotos des ELT. Auf der rechten Seite des Stands steht ein Glücksrad mit einem astronomischen Design, daneben ein Barhocker sowie eine VR-Brille, die Besucherinnen und Besucher ausprobieren können. Links steht eine Infotafel mit der Überschrift „Raumfahrt“ und dem Hinweis „Extremely Large Telescope (ELT) – das weltweit größte Auge im Himmel“. Das Logo der ESO ist ebenfalls sichtbar. Der Stand wird von Mitarbeiterinnen und Mitarbeitern des Max-Planck-Instituts für Astronomie (MPIA) und des Max-Planck-Instituts für extraterrestrische Physik (MPE) betreut. Er ist Teil des Programms zum Tag der offenen Tür der Bundesregierung, bei dem Forschungseinrichtungen ihre Projekte vorstellen.
