"This discovery poses a challenge to the Lambda Cold Dark Matter model, which may struggle to account for the formation of such small, aligned groups of galaxies in isolated environments." When you ...

Galaxies like the Milky Way grow by merging with smaller galaxies over billions of years, unlike dwarf galaxies, which have long been thought to lack the heft to attract mass and grow in the same way.

PHOENIX —Thousands of newly spotted galaxies are dressed for a Victorian ball: in hoop skirts. The cache of “polar structure galaxies” — with large starry or dusty structures oriented perpendicular to ...
