Scientists have replicated the formation of galaxies, with a simulation now only offering a peek into how these gigantic structures are born and evolve, but also letting you hear them grow. The ...

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 ...

Scientists have created the most realistic simulations yet of how galaxies formed and changed over time. These simulations let us both see and even hear how galaxies evolved in the early universe.

Scientists have discovered a galaxy as it was 13 billion years ago, 800 million years after the Big Bang. It contains possible evidence of the universe's first stars and is one of the most chemically ...

Galaxies are like cosmic gems, each with characteristics including size and shape that make them distinct. A new gallery released today from NASA's Chandra X-ray Observatory and other telescopes ...

Powerful jets from supermassive black holes can disturb star-forming gas far beyond a galaxy’s visible edge, leaving a glowing trail hundreds of thousands of light-years long. By keeping this gas hot ...
