Mercury, the smallest planet in the solar system, holds an outsized secret that some researchers believe could reshape how ...

Smaller bodies of rock, metal, ice, and dust can be found scattered throughout space. These objects travel on their own courses, sometimes silently beyond Jupiter and occasionally quite close to Earth ...

The Science: Europa has been considered as a top contender for alien life for even longer than Enceladus, thanks to its massive under-ice liquid water oceans. It also displays water vapor plumes ...

Their observations of a faint, cool M-dwarf star called LHS 1903 revealed a system with a rocky world at its outer edge. LHS ...

Ed Miliband has approved plans for new solar farms that could cover an area of farmland nearly as large as Manchester.

Hubble observations reveal a giant, turbulent planet-forming disk that may reshape theories of how planetary systems develop.

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 ...

Processed Hubble Space Telescope image of interstellar object 3I/ATLAS showing a sharply defined anti-sunward jet (PA ≈ 290°) and a faint opposing anti-tail, revealed using rotational-gradient ...

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 ...

This image presents a grid of colour-enhanced astronomical observations, each depicting a circumstellar disc—structures of dust and gas surrounding stars. Every square in the grid represents a ...
