Mysterious planetary mass objects that wander the cosmos alone could be created when young star systems clash. They aren't ...

An international research team led by the University of Vienna has discovered that the solar system traversed the Orion star-forming complex, a component of the Radcliffe Wave galactic structure, ...

Our Solar System is in motion and cruises at about 200 kilometres per second relative to the center of the Milky Way.

Earth may have cooled during a close encounter with dense star clouds. Interstellar dust from the Orion region might have ...

How do rogue planetary-mass objects -- celestial bodies with masses between stars and planets -- form? An international team of astronomers has used advanced simulations to show that these enigmatic ...

Rogue planet find makes astronomers ponder theory. WASHINGTON (Reuters) -- Eighteen rogue planets that seem to have broken all the rules about being born from a central, controlli ...

Millions of years ago, our Solar System traveled through a densely populated galactic region and was exposed to increased interstellar dust.

"We passed through the Orion region as well-known star clusters like NGC 1977, NGC 1980, and NGC 1981 were forming," Alves notes. "This region is easily visible in the winter sky in the Northern ...

Astronomers have long been puzzled by mysterious, planet-sized objects drifting freely through space, unattached to any star.

Astronomers have proposed a new theory on the formation of free-floating planetary-mass objects (PMOs), suggesting they form ...

Star clusters are formed when gravity pulls young stars together, forcing them to orbit each other. A star cluster can ...
