Researching the immune system in space could have payoffs for human aging on earth. Scientists have revealed how the lack of gravity affects the cells of the immune system at single cell resolution.

To live on the moon or Mars, humans will need heat and air conditioning that can operate long term in reduced gravity and temperatures hundreds of degrees above or below what we experience on Earth.

Dark matter isn’t everywhere in equal amounts. Some areas of the universe are packed with it, while others have almost none.

Gravity is the unseen force that shapes the universe, yet we rarely give it much thought. First explained by Sir Isaac Newton, it is the pull that draws objects toward one another based on their mass ...

A Rutgers-led team of scientists has uncovered evidence of how galaxies expand by tracing the invisible scaffolding of the universe created by a mysterious substance known as dark matter. Subscribe to ...

Scientists have spent decades trying to understand how gravity operates at its most basic scale. However, no theory has come close to fully explaining it. Now, though, a new theory could finally give ...

The James Webb Space Telescope's discovery of unusually bright and massive galaxies soon after the Big Bang has cast doubt on the standard model of galaxy evolution and bolstered a rival theory for ...

Using the James Webb Space Telescope, scientists spotted thin and thick disks in galaxies as far back as 10 billion years ago—something never seen before. These observations reveal that galaxies first ...

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 ...
