Galaxies’ varying rotation speeds?

All disk galaxies take around a billion years to complete a full rotation, regardless of their size or composition. This discovery will aid in understanding how galaxies function. Other universal truths include the rotation of everything in space and the size of various galaxies. While space still holds countless mysteries, researchers recently uncovered an extraordinarily […]

Galaxies in universe: how many?

The Hubble Space Telescope’s 3D modeling has estimated that there are around two trillion galaxies in the universe, far more than the previous estimate of 100-200 billion. The majority of galaxies have yet to be studied, and future telescopes may reveal interesting properties. A galaxy contains billions of stars, held together by gravity. Within each […]

Galaxies’ size?

The universe has around 100 billion galaxies, each with between 10 million and 1 trillion stars. Galaxies are organized into superclusters and filaments, with the Eridanus Supervoid being the largest void. The Milky Way has 200-400 billion stars and is part of the Local Group, which contains over 35 galaxies. The possibility of spacefaring extraterrestrial […]
