Astronomers have detected one of the darkest objects ever seen at a record cosmic distance—only with the assistance of ...

Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists’ best current ...

Faint hydrogen signals from the cosmic Dark Ages may soon help determine the mass of dark matter particles. Simulations suggest future Moon-based observatories could distinguish between warm and cold ...

Calculating the total mass of the universe is not simple, because most of the mass is invisible. In a pie chart of the contents of the universe, only 5 percent is normal matter, atoms that make up all ...

In a first-of-its-kind test, scientists used a levitated magnet to search for dark matter, the unidentified substance believed to be present throughout the cosmos. If dark matter is made up of ...
