By studying what makes the Milky Way unique, astronomers are hoping to understand our galaxy’s past and unravel the mystery ...

A distant galaxy 12 billion light-years away shows signs of being a jellyfish galaxy, with trailing streams of gas caused by ...

When it comes to star formation, not all galaxies are the same. Some are quenched, meaning they've depleted their star ...

The most distant known example of what astronomers call a “jellyfish galaxy” has been spotted by NASA’s James Webb Space ...

Using the James Webb Space Telescope (JWST), astronomers from Canada and Switzerland have discovered a new galaxy, which ...

A new study suggests they may have a ghostly shadow—trailing dark matter spirals hovering above and below them. A team of ...

We present new analysis from the Group Environment Evolution Collaboration 2 (GEEC2) spectroscopic survey of galaxy groups at 0.8 < z < 1. Our previous work revealed an intermediate population between ...

A galaxy may be able to draw gas more effectively as its mass grows, which speeds up the formation of new stars as this growth is forever. Galaxies eventually go through a process known as “quenching, ...

Exploring the Quenching of Star Formation The second study focuses on star formation in the satellites. The star formation rate (SFR) is an important metric in understanding galaxy evolution. The ...

The star formation rate (SFR) is an important metric in understanding galaxy evolution. The research shows that star formation is still active in the satellite galaxies, but the closer they are to the ...
