UrduHace 100 años, Edwin Hubble descubrió evidencia decisiva sobre la existencia de otras galaxias más allá de la Vía Láctea. Esta imagen es una porción del enorme Cúmulo de Perseo y muestra sus “universos islas” con asombroso detalle, gracias a las avanzadas capacidades del telescopio Gemini Norte, la mitad boreal del Observatorio Internacional Gemini. Las observaciones de este tipo de objetos siguen aportando información no sólo de sus características individuales, sino también sobre profundos misterios cósmicos, como la materia oscura.

Gemini North Captures Galactic Archipelago Entangled In a Web Of Dark Matter
100 years ago Edwin Hubble discovered decisive evidence that other galaxies existed far beyond the Milky Way. This image, captured by the Gemini North telescope, one half of the International Gemini Observatory, features a portion of the enormous Perseus Cluster, showcasing its ‘island Universes’ in awe-inspiring detail. Observations of these objects continue to shed light not only on their individual characteristics, but also on cosmic mysteries such as dark matter.
NASA’s Webb Reveals Distorted Galaxy Forming Cosmic Question Mark
Astronomers using NASA’s James Webb Space Telescope were surprised to find a distant, red galaxy distorted into the shape of a question mark. A specific, rarely-seen type of natural gravitational lens is causing the galaxy to appear multiple times.
Astronomers find missing link in massive black hole formation
Newly identified fast-moving stars in the star cluster Omega Centauri provide solid evidence for a central black hole in the cluster. With at least 8,200 solar masses, that black hole is the best candidate for a class of black holes astronomers have long believed to exist: intermediate-mass black holes, formed in the early stages of galaxy evolution.
Las capas estelares de una cebolla galáctica
En esta imagen repleta de galaxias muestra las capas simétricas similares a la de una cebolla de la galaxia NGC 3923, captada por la Cámara de Energía Oscura del Departamento de Energía de EE.UU (DOE) montada en el Telescopio de 4 metros Víctor M. Blanco de la Fundación Nacional de Ciencias (NSF) en el Observatorio Interamericano Cerro Tololo en Chile, un Programa de NOIRLab de NSF.
Stellar Layers of a Galactic Onion
The symmetrical, onion-like layers of shell galaxy NGC 3923 are showcased in this galaxy-rich image taken by the US Department of Energy’s (DOE) Dark Energy Camera mounted on the National Science Foundation’s (NSF) Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory in Chile, a Program of NSF’s NOIRLab.
Researchers discover tiny galaxy with big star power using James Webb telescope
Using first-of-their-kind observations from the James Webb Space Telescope, a University of Minnesota Twin Cities-led team looked more than 13 billion years into the past to discover a unique, minuscule galaxy that could help astronomers learn more about galaxies that were present shortly after the Big Bang.
