Distant galaxies, interacting galaxies, whose shape has been forged by the mutual gravitational influence, but also galaxies forming groups and clusters, kept together by gravity—they are the protagonists of three new images released by the VLT Survey Telescope (VST).

The first crewed launch of Boeing's Starliner spaceship will have to wait until at least Friday to give ground teams time to analyze a malfunctioning rocket valve, pushing back a high-stakes test trip to the International Space Station.

Billionaire Jared Issacman, who flew to space once with SpaceX, is already set for launch No. 2 in early summer.

Bright, starry spiral arms surround an active galactic center in this new NASA Hubble Space Telescope image of the galaxy NGC 4951.

One day the SpaceHopper will be deployed on space missions to explore relatively small celestial bodies such as asteroids and moons. These are thought to contain valuable mineral resources that could be of use to humankind in the future. The exploration of these bodies could also give us insights into our universe's formation.
