In a new study, astronomers show how gas expelled in the merger of two small galaxies can linger across vast distances for billions of years, where it may eventually feed gas to more massive galaxies to make new stars. […]

A glittering host of galaxies populate this rich image taken with ESO's VLT Survey Telescope, a state-of-the-art 2.6-m telescope designed for surveying the sky in visible light. The features of the multitude of galaxies strewn across the image allow astronomers to uncover the most delicate details of galactic structure. […]

Observations made with ESO's Very Large Telescope have for the first time clearly revealed the effects of Einstein's general relativity on the motion of a star passing through the extreme gravitational field very close to the supermassive black hole in the center of the Milky Way. This long-sought result represents the climax of a 26-year-long observation campaign using ESO's telescopes in Chile. […]

Scientists have clarified how gravity affects the shape of matter near the black hole in binary system Cygnus X-1. Their findings may help scientists further understand the physics of strong gravity and the evolution of black holes and galaxies. […]

A thin gap has been discovered on the Hertzsprung-Russell Diagram (HRD), the most fundamental of all maps in stellar astronomy, a finding that provides new information about the interior structures of low mass stars in the Milky Way Galaxy, according to a new study. […]
