Its spiral stretches 100,000 light ... momentum necessary for the formation of large disks. Additionally, the frequent mergers of gas-rich galaxies in this crowded region may have contributed ...

Usually, rapid mergers between galaxies would disrupt the delicate spiral structures, turning them into more chaotic shapes. However, the Big Wheel managed to quickly grow to a surprisingly large ...

He and his colleagues were looking for quasars, energetic regions at the heart of some galaxies, with the James Webb Space Telescope in November 2022 when a “large spiral galaxy popped up”.

Shapley argued that the spiral nebulae were small and in the Milky Way, while Curtis took a more radical position that they were independent galaxies, extremely large and distant. At the time ...

If you see a pair of bright eyes in the inky depths of space, you’re seeing what a team of astronomers spied last year—a rare formation created by the grazing collision of two spiral galaxies.

"The full potential of Euclid to learn more about dark matter and dark energy from the large-scale structure ... recognize various features of galaxies, such as spiral arms, in early Euclid ...

Extraordinary images from the Euclid space telescope have captured 26 million galaxies, some as far off ... ESA has now released the first large-scale data from this mission, beginning with ...
