Like stretch marks left on skin that expanded too quickly or cracks embedded in freezing ice, cosmic strings are artifacts of ...

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole new model to account for gravity’s influence.

Researchers at the Max Planck Institute for Extraterrestrial Physics (MPE), in collaboration with astrophysicists from the ...

In inertial confinement fusion, a capsule of fuel begins at temperatures near zero and pressures close to vacuum. When lasers compress that fuel to trigger fusion, the material heats up to millions of ...

As the threat of falling spacecraft increases, using earthquake sensors to detect the effects of their sonic booms could ...

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study ...

In this episode of Space Minds, host Mike Gruss is joined by SpaceNews journalists Jason Rainbow, Sandra Erwin, Jeff Foust and Debra Werner for a wide-ranging conversation on the space stories that ...

In 2026, there will be journeys to the moon and Mars, new visions of the cosmos and a solar eclipse that might be worth traveling for. In 2026, there will be journeys to the moon and Mars, new visions ...

The original version of this story appeared in Quanta Magazine. Standing in the middle of a field, we can easily forget that we live on a round planet. We’re so small in comparison to the Earth that ...

The International Space Station was painstakingly assembled segment by segment, launched into orbit by many expensive and logistically complex rockets. Now there’s intense interest in a radically ...

In this episode of Space Minds, host David Ariosto speaks with Juan Alonso — CTO and Co-founder of Luminary Cloud and professor at Stanford University — about the rapid transformation underway in ...

Artificial intelligence increasingly requires so much space and power that we may run out of both on Earth. As a solution, tech companies are looking to do business in space by creating celestial data ...
