The James Webb Space Telescope has imaged a collision between two galaxies that appears to have created a beaming smile in ...

NASA's Hubble Space Telescope helped astronomers find more supermassive black holes in the early universe than previous estimates.

An interaction between an elliptical galaxy and a spiral galaxy, collectively known as Arp 107, seems to have given the ...

A new image from the James Webb Space Telescope captures one of the universe's most dramatic events: the colliding of two galaxies.

Smile for the camera! An interaction between an elliptical galaxy and a spiral galaxy, collectively known as Arp 107, seems to have given the spiral a happier outlook thanks to the two bright “eyes” ...
