There are a couple of ways that scientists can date planets, so which planets formed first in our solar system?

Tiny shavings from a single meteorite could completely overturn our understanding of how the solar system formed, after the space rock turned out to be older than expected. Previous research suggests ...

New research from Rice University suggests that the giant planet Jupiter reshaped the early solar system in dramatic ways, ...

Around a Sun-like star just 1,300 light-years away, a family of planets has been seen in its earliest moments of conception. Astronomers analyzed the infrared flow of dust and detritus left over from ...

Astronomers have witnessed the creation of a solar system for the first time. Data captured by the ALMA telescope in Chile and the James Webb Space Telescope showed planets forming around a star in ...

Researchers are studying eccentric warm Jupiters, giant exoplanets that follow odd, elongated orbits unlike anything in our solar system.

The Sun's formation caused temperature differences in the surrounding disk of gas and dust. Inner, hotter regions formed rocky planets from less volatile elements. Outer, colder regions allowed ...

Jupiter is already the biggest planet by far in our solar system, but new research suggests it was somehow once even larger than it is now. Twice as large, in fact. To put that into context, those ...

Astronomers found an interstellar "tunnel" - a cosmic channel that connects our solar system to distant stars, according to a ...

The Milky Way and Andromeda galaxies are predicted to collide and merge between 3.9 and 5.6 billion years from now, based on observed relative motion. The merger process will involve multiple ...

A new study suggests yet another theory for a possible extra planet in our solar system, likely of a size between Mercury and ...
