Astronomers have investigated three ultra-faint dwarf galaxies that are located in a region of space far away from the ...

There are three main types of galaxies: elliptical, spiral and irregular. The largest galaxies are called elliptical because they look like big globes of light emitted from a multitude of stars.

While we have plenty of spiral galaxies, like our own Milky Way, these are only the most common types of galaxies out there. There are still others, like elliptical or irregular galaxies.

In 1920, astronomers Harlow Shapley and Heber Curtis held a Great Debate. Shapley argued that the spiral nebulae were small and in the Milky Way, while Curtis took a more radical position that they ...

After hundreds of hours of observations, researchers captured a highly detailed image of a long filament of the "cosmic web" ...

Within galaxies, as stars were being born ... The supernova pictured here is of a smaller type, used by astronomers to determine distance. This one appears to us now as it looked when the universe ...

Ultra-faint dwarf galaxies are the faintest type of galaxy in the universe. Typically containing just a few hundred to a thousand stars—compared with the hundreds of billions that make up the ...

In a significant astronomical discovery, researchers found three ultra-faint dwarf galaxies, offering new insights into the ...

These galaxies are thought to be the most common in the nearby Universe and might be the types of galaxies where life can develop given the nature of their formation history. However, astronomers ...

"The large volume of data from Rubin will give us a sample of all kinds of Type Ia supernovas at a range of distances and in many different types of galaxies." The Vera C. Rubin Observatory will ...

"Our measurements imply that the supermassive black hole mass is 10% of the stellar mass in the galaxies we studied." Using the James Webb Space Telescope (JWST), astronomers have discovered ...
