Austrian physicist Erwin Schrödinger developed quantum theory’s wave equation, which describes quantum systems as waves that ...

NASA’s DART mission proved that a spacecraft can nudge an asteroid system in space, offering a real test of planetary defense. NASA’s DART (Double Asteroid Redirection Test) spacecraft changed the ...

What can rocky planets orbiting in the outer parts of a solar system teach scientists about planetary formation and evolution? This is what a recent study published in Science hopes to address as a ...

The James Webb Space Telescope and the Chandra X-ray Observatory have captured the clearest image yet of a galaxy cluster in the making, seen when the universe was only one billion years old. When you ...

"It highlights gravity's possible hidden complexity and invites a reevaluation of where dark matter effects originate." When you purchase through links on our site, we may earn an affiliate commission ...

Here’s what you’ll learn when you read this story: Einstein’s Theory of General Relativity, an immensely important update to Newton's Law of Universal Gravitation, is currently our best approximation ...

A team of astronomers found no radio signals from the comet that would suggest it is an extraterrestrial spaceship. The comet was confirmed in July 2025 as the third known object to enter our solar ...

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 ...

Rising launch cadences have dramatically increased orbital debris, posing critical risks to spacecraft and operations, as highlighted by incidents like the Shenzhou-21 stranding. The primary barrier ...

Fragments of energy may be the fundamental building blocks of the universe. The theory combines the ideas of particles and waves into a concentration of energy that flows throughout space and time.

Sometimes, what goes up doesn’t come back down — instead, it becomes a problem. Junk is accumulating in space at a fantastic pace, millions of pieces orbit the Earth, from broken satellites to lost ...
