Description: En astronomía, el término «espacio» tiene dos acepciones: el espacio (o «espacio exterior») es todo lo que existe más allá de la Tierra; desde un punto de vista más técnico, se refiere a las dimensiones de longitud, anchura y profundidad en las que existen todas las cosas (a diferencia del tiempo, que a veces se considera una cuarta dimensión).

The Horsehead Nebula
Caption: This image shows the Horsehead Nebula, located at a distance of about 1,300 light-years from Earth in the Orion constellation, one of the most iconic examples of a dark nebula. A dark nebula is a dense cloud of interstellar dust and cold gas that absorbs and scatters visible light, preventing background stars and glowing gas from reaching our eyes. This false-color image combines data captured through multiple narrowband filters, each isolating light from different elements in the nebula. The dark, horse-shaped silhouette appears sharply outlined against the luminous nebula behind it, where energetic radiation from nearby young stars causes the gas to glow. The uneven distribution of visible stars in this image is not random: regions rich in dust in the lower part of this image appear almost empty, while clearer areas reveal many background stars. The dust acts like a cosmic curtain, hiding stars that lie behind it while allowing stars in front of the cloud to remain visible. Studying such regions helps astronomers understand how nebulae serve as environments where new stars can form.
