There are hundreds of billions of galaxies in the known universe, but scientists still have a lot of questions about how galaxies form, grow and even die. Science Trek is available to stream on ...

Cold gas does not look dramatic at first glance. Neither does dust. Yet those two quiet ingredients sit at the center of a new effort to build a far more realistic picture of how galaxies formed. They ...

Magnetic fields that stretch across thousands of light-years should take a very long time to organize. Standard dynamo theory puts that timeline at roughly 5 to 10 billion years in galaxies. Yet ...

The study challenges assumptions that galaxies are too vast to be affected by small changes.

Scientists have found a remarkably small yet bright object from the early universe that doesn’t make sense in our existing models of how stars and galaxies formed, even our own Milky Way. That means ...

The most realistic picture yet of how galaxies formed and then evolved from the beginning of time has been revealed in a suite of new and unique audiovisual simulations. These data, accepted for ...

How do you find a galaxy that never formed? The standard cosmological model predicts the existence of “failed” galaxies — clumps of dark matter that captured gas but never birthed a star. Because they ...

Astronomers may have uncovered a hidden supermassive black hole inside the famous Antennae galaxies NGC 4038/4039, a pair of ...
