There are an estimated 100 billion galaxies in all of the observable universe. [1] . On the order of 100,000 galaxies make up the Local Supercluster, and about 51 galaxies are in the Local Group (see list of nearest galaxies for a complete list).

2023年2月20日 · The new Hubble Space Telescope image is part of an investigation into the origins of the largest and most massive galaxies in the universe, which astronomers call Brightest Cluster Galaxies...

2023年2月17日 · These three galaxies are set on a collision course and will eventually merge into a single larger galaxy, distorting one another’s spiral structure through mutual gravitational interaction in the process.

2025年1月28日 · Astronomers classify galaxies into three major categories: elliptical, spiral and irregular. These galaxies span a wide range of sizes, from dwarf galaxies containing as few as 100 million stars to giant galaxies with more than a trillion stars.

The 3 types of galaxies are: Spirals; Ellipticals; Irregular and Lenticular; Galaxies are just large accumulations of stars, planets, and other solar remnants. Astronomers estimate as many as 100 billion galaxies in the expanding universe. We observe galaxies using the …

2011年8月25日 · The spiral shapes of two of these galaxies appear mostly intact. The third galaxy (to the far left) is more compact, but shows evidence of star formation. Two of the three galaxies are forming new stars at a high rate.

2023年3月1日 · These three galaxies are set on a collision course and will eventually merge into a single larger galaxy, distorting one another’s spiral structure through mutual gravitational interaction in...

2022年2月22日 · The Hubble Space Telescope has imaged the ongoing collision of three distant galaxies. The picture shows bright swirls of dust and stars from the galaxies that make up the merger event IC 2431.

2023年2月14日 · Galaxies collide in this stunning image recently taken by NASA's Hubble Space Telescope, centered on the constellation Bootes. The three galaxies in question have been designated as SDSSCGB...

2023年2月17日 · NASA and the European Space Agency's Hubble Space Telescope captured a rare view of not just two, but three galaxies on a collision course. A closer look at the galactic trio. The trio is...
