NASA shared some new infrared images of the 3I/ATLAS interstellar comet this week, showing the visitor brightening up in a dramatic outburst while exiting a solar system. The images were taken by the ...

Every once in a while, the outer solar system reminds us that we've only discovered a negligible portion of it, and that the vast majority is still full of surprises. The latest example of this is a ...

The first few exoplanets were discovered in the early 1990s. But it wasn’t until the early 2000s, when astronomers began carrying out large-scale, long-term surveys of other stars, that we started to ...

HELSINKI — China has published coordinated papers outlining dual missions to the solar system’s edge, suggesting the long-studied project is nearing formal approval. A lead paper on the design and key ...

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 ...

Nothing manmade has reached further from Earth than the Voyager series of spacecraft. Hurtling away from the sun at 38,000 miles an hour, the duo have now traveled over 12 billion miles, with Voyager ...

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 ...
