The researchers said that the "hydroxyl gigamaser" was generated by the merger of two galaxies some 8 billion light-years away.

The James Webb Space Telescope has revolutionized astronomy in just two years of operations, but how can it see a galaxy 33.8 billion light-years away in a universe that is only 13.8 billion years old ...

A galaxy made almost entirely of dark matter, an elusive form of matter that doesn’t interact with light, was spotted by Hubble 250 million light-years from Earth.

A newly discovered jellyfish galaxy, seen as it existed 8.5 billion years ago, is challenging assumptions about conditions in the early universe. Astrophysicists at the University of Waterloo have ide ...

"One day soon we may be able to see these 'missing' galaxies, which would be hugely exciting and could tell us more about how the universe came to be as we see it today." When you purchase through ...
