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

Observing real galaxies in space can only provide snapshots in time, so researchers who want to study how galaxies evolve over billions of years have to revert to computer simulations

A study led by researchers from the Instituto de Astrofísica de Canarias (IAC) puts a sequence to the events which gave rise to our galaxy

By automating the discovery process, scientists can quickly scan sets of images, and return precise predictions with minimal human interaction
