New, detailed images of the Cartwheel Galaxy produced by Webb's powerful infrared camera

New research shows that the axioms of cosmology may have been different in an infant universe

The fossil could teach scientists about how galaxies form and confirm their understanding of cosmology and dark matter

Six early, massive, "dead" galaxies have run out of the cold hydrogen gas needed to make stars

Scientists have succeeded in dating some of the oldest stars in our galaxy with unprecedented precision

Galaxy's appearance at different radio frequencies helps scientists learn more about how active galaxies can change dramatically on decade time scales

Gas halos are the perfect food for supermassive black holes at the center of early galaxies, which are now seen as they were over 12.5 billion years ago

The monster black hole is located 15 thousand light-years from Earth and has been named LB-1 by the researchers

Menacing-looking 'face' formed by titanic smashup between two galaxies

The discovery suggests that a large structure such as a protocluster already existed at a time when the universe was only about 800 million years old—six percent of its present age
