A galactic photo shoot has captured more than 3 billion stars and galaxies in one of the biggest sky surveys ever. A dark-energy camera on a telescope in Chile made the observations over two years ...
Most galaxies, including our Milky Way, contain tens of billions of stars that are readily observable. Even in nearby galaxies, such as Andromeda, which is about 2.5 million light-years away ...
The most powerful telescope to be launched into space has made history by detecting a record number of new stars in a distant galaxy. NASA's James Webb Space Telescope, history's largest and most ...
The stars move along random orbits with no preferred direction. These galaxies contain little or no interstellar dust, few star-forming regions, and older stars. [66]: 877–878 Elliptical galaxies may have been formed by other galaxies merging. [66]: 939
A look at the biggest things in the universe, such as the cosmic web, which connects galaxies together along threads of dark matter, or the Lyman-alpha blob, which is a bubble containing countless galaxies. Also a look at super-galaxies, super massive black holes, "radio lobes", and the biggest void in space.
(descriptions from video tape box) "21st Century Cosmos" – Our perception of the universe has changed dramatically from thoughts of a starry, unknown realm to knowledge of the countless galaxies that surround us, yet the scale of the cosmos remains a mystery. How old is the universe? How much matter and energy does the universe contain?
Video from NASA shows two galaxies, about 80 million light-years away from Earth, forming the shape of "blood-soaked eyes."
Size (left) and distance (right) of a few well-known galaxies put to scale. The following is a list of notable galaxies.. There are about 51 galaxies in the Local Group (see list of nearest galaxies for a complete list), on the order of 100,000 in the Local Supercluster, and an estimated 100 billion in all of the observable universe.
