These galaxies, however, are still relatively nearby, and their velocities are dominated not by the universe’s expansion but by the push and pull of other galaxies in their host clusters.

Astronomers have found early evidence of the Universe’s transformation from a foggy, opaque state to a transparent one, ...

The Milky Way galaxy we live in, like other galaxies in the universe, has bubble-like structures formed mainly during the birth and activity of high-mass stars. These so-called Spitzer bubbles ...

In other words, the Big Wheel is in the universe’s old city: a very ancient and crowded part of the cosmos, in which galaxies intermingle, swapping star systems, asteroids, and dust in the process.

Scientists using the James Webb Space Telescope have identified an ancient and faraway galaxy that provides evidence that an ...

Scientists have made the record-breaking detection of oxygen in an ancient galaxy that existed just 300 million years after the Big Bang. The detection is prompting astronomers to rethink how quickly ...

JADES-GS-z14-0 was spotted alongside several other similarly early galaxies ... holes evolved within primordial galaxies when the 13.8 billion-year-old universe was very young.

other galaxies, and galaxy clusters. In a sense, it's tracing the evolution of the universe from its infancy to modern times. But, that data also points toward something else, according to Erminia ...
