NGC 3640, a scarred elliptical galaxy caught on camera by the VST, shows evidence of past galactic feasts. But its tiny neighbor, NGC 3641, seems to be slipping away unscathed — a cosmic near-miss.

Galaxies come in many different variations, but astronomers classify them into four main types: spiral, elliptical, irregular and peculiar.

“This means that the distance between galaxies is increasing constantly. We have measured how far apart elliptical galaxies are from one another today. Using these data and taking into account ...

Along with a number of neighbouring galaxies — including our closest galactic neighbour, the Andromeda Galaxy — it forms what is referred to as the “Local Group” of galaxies, a galactic agglomeration ...

However, not all spiral galaxies are created equal, as two recent images from the Hubble Space Telescope show. The image above shows galaxy NGC 3596, a neat and orderly spiral galaxy. And the image ...

NASA's Galaxy Zoo project invites volunteers to classify James Webb Space Telescope images, aiding scientists in understanding galaxy evolution. Participants analyze galaxy shapes, contributing to ...
