There are dark places out there in the deep universe, vast Saharas hundreds of millions of light years across, empty except for a stray hydrogen atom or a bit of radiation. They are the cosmic voids, ...

From an early age, we are taught to understand that the planets of our solar system change in position while orbiting a central star, the sun. But does the sun itself move within the solar system?

Astronomers have discovered that 3I/ATLAS is carrying methanol and other chemicals that were probably important in the origin ...

This story sounds wild—even incredible. Black holes! Dark matter! Jostling planets! Yet the scenario is plausible—and testable soon. Black holes the size of an atom that contain the mass of an ...

There’s a bit of a paradox about our galaxy: it’s both jam-packed with stars and cavernously empty. The Milky Way is crowded in the sense that it holds hundreds of billions of stars, as well as ...

Meet the surprising, oddball worlds moving around our solar system. From meteorites that impact Earth, to a moon that orbits backwards, to an imposter lurking in the asteroid belt, a variety of ...

About 4.6 billion years ago, a celestial cloud collapsed, paving the way for our solar system to form. Then, a nebula with strong gravitational pull took shape, kick-starting the birth of the sun. But ...
