Astronomers have discovered a system of five merging galaxies just 800 million years after the Big Bang, in a find that is ...

The scientific community is abuzz with the recent revelations made by the James Webb Space Telescope. This revolutionary ...

Scientists have mapped out the dark matter around some of the earliest, most distant galaxies yet. The 1.5 million galaxies appear as they were 12 billion years ago, or less than 2 billion years ...

New observations by NASA's Hubble Space Telescope are expanding astronomers' understanding of the ways in which galaxies continuously recycle immense volumes of hydrogen gas and heavy elements ...

Astronomer and Pluto mission leader S. Alan Stern explores how the field has transformed during his decades-long career.

What was the universe like in the first few hundreds of millions of years after it came into existence? How did the first ...

A sample of galaxies dating to the first 2 to 3 billion years of the universe contain much heavier elements, and appear to be far hotter, than scientists expected.

Overlooked galaxies from when the universe was younger than 2 billion years old could be the ancestors of other ancient and modern monster galaxies.

The galaxies date back to 500 to 700 million years after the Big Bang itself and could change our understanding of the universe.

The universe is awash in islands of matter — some 100 billion galaxies make up the basic building blocks of the cosmos.

These galaxies contain 100 billion times the mass of the sun in stars, and if you glance at any one of them, you are far more likely to see the signs of an eating black hole than in any other ...

The patterns formed by spiral galaxies show that the universe may have a defined structure and suggest that the early universe could have been spinning, according to a computational astronomer.
