Ring galaxies and polar-ring galaxies offer natural laboratories for investigating how dynamical processes shape star formation. In collisional ring systems, a near head-on encounter launches a ...

Webb and Hubble sink deep into the dazzling Whirlpool Galaxy — Space photo of the week Hubble revisits stunning Trifid Nebula after 30 years, and spots a growing jet of energy — Space photo of the ...

These findings suggest that the supermassive black hole at the centre may be preventing new stars from forming by pushing out ...

Astronomers have long sorted galaxies into types based on their visible structure. Spiral galaxies, like our Milky Way, have a flat disk, winding spiral arms and ongoing star formation. Ellipticals ...

Early-type galaxies, encompassing elliptical and lenticular systems, host the oldest and most dynamically relaxed stellar populations in the local Universe. Their stars typically formed in rapid, ...

The universe teems with galaxies, but in our neighborhood of the universe, some are rarer than others. Most of the local galaxies are young, vibrant things that are bursting with freshly born stars or ...
