The solar system’s most giant planet is slightly less of a giant than scientists once thought. Jupiter, a planet so huge it could hold 1,000 Earths, is 8 kilometers less wide at its equator and 24 ...

Earth may owe some of its properties to a nearby star that blew up just as the solar system was forming. This pattern, which saw a supernova bubble envelop the sun and shower it with cosmic rays, may ...

Earth has the perfect combination of a livable atmosphere and a protective magnetic field that prevents the Sun's harmful radiation and radioactive solar winds from damaging us, allowing us to live on ...

A new study with the incredibly exciting title of "Overdispersed Radio Source Counts and Excess Radio Dipole Detection" has announced quite a thrilling discovery, indeed: Our solar system is moving ...

Astronomers have spotted an intriguing cluster of objects in the Kuiper belt, the enormous, donut-shaped region of icy objects beyond the orbit of Neptune. This latest “inner kernel” was identified by ...

Explore the vastness of the Solar System in this video, which accurately showcases the relative sizes of the planets and their actual distances from the Sun. Trump says Republicans should 'nationalize ...

Simulations reveal that Jupiter’s rapid growth disrupted the early solar system, creating rings where new planetesimals formed much later than expected. These late-forming bodies match the ages and ...

Our solar system is a smashing success. A new study suggests that from its earliest period — even before the last of its nebular gas had been consumed — Earth’s solar system and its planets looked ...

The National Aeronautics and Space Administration has confirmed an interstellar object is passing through our solar system. The object is a comet hailing from the direction of the constellation ...

3I/ATLAS likely weighs more than 33 billion tons. The interstellar object hurtling toward the inner solar system, where Earth is located, is much larger than previously thought, astronomers say. A ...

For the first time, astronomers have directly measured a solar-system-size corona around a distant supermassive black hole, thanks to a rare cosmic alignment. When you purchase through links on our ...
