Typically, telescopes are synonymous with bringing far-off objects close, but the newest member of the solar system was discovered using wide-field imaging. The Subaru Telescope has spotted a ...

For example, the first mile-sized planetesimals in our solar system–which grew to become celestial bodies like Earth or Jupiter’s core–formed right after the condensation of these same ...

The Solar System, home to Earth and countless other fascinating planets and moons, exists within the Milky Way galaxy. But exactly where are we in this vast galaxy? The Milky Way is a massive ...

Astronomers have observed an object that originated from beyond our solar system, thought to be an interstellar comet, speeding through our celestial neighborhood.

Astronomers using the Subaru Telescope have discovered a strange new body in a weird orbit at the edge of the solar system, which could be bad news for Planet Nine theories.

Astronomers have discovered a "fossil" body residing on the outskirts of the solar system, according to new research. The object – which goes by the formal designation 2023 KQ14 but is nicknamed ...

Scientists have thought that our solar system's inner rocky planets — Mercury, Venus, Earth and Mars —formed first (around 4.566 billion years ago), while gas giants and icy bodies in the ...

Our solar system has been around for 4.6 billion years. While that sounds like a long time, it's just a blip in the 13.8 billion-year story of the universe.

Unfortunately, If it were to swing too close to our solar system, it might just send our planet hurtling into the sun. It could even eject Earth out of the solar system completely.

This process, called accretion, is how everything in the solar system – planets, moons, comets and asteroids – came into being. Telescopes can see young solar systems being born.

The story begins with a puzzle in the outer solar system. Scientists noticed that small icy bodies called Kuiper Belt Objects, which orbit far beyond Neptune, seem to be clustered together in ...
