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 ...

Discovery of oxygen raises new questions about how solar system formed. In this undated photo, Rosetta finds oxygen on comet 67P. ESA/Rosetta/NavCam – CC BY-SA IGO 3.0 — -- The European Space ...

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 ...

The workings of our solar system are roughly the same now as they have been for millions of years. Moons circle their planets, the planets circle the sun, the sun’s magnetic fields and sunspots wax ...

About 4. 6 billion years ago, the Solar System formed from a cloud of dust and gas collapsing in on itself due to gravity.

Astronomers are investigating a strange class of exoplanets known as eccentric warm Jupiters — massive gas giants that orbit their stars in unexpected, elongated paths. Unlike their close-orbiting ...

Comet C/2025 A6 (Lemmon) is this year’s brightest comet visible from Earth—an icy relic from the solar system’s origins that ...

A new study suggests yet another theory for a possible extra planet in our solar system, likely of a size between Mercury and Earth. The authors dubbed it Planet Y.

One of the studies, published in the journal Nature Astronomy, shows that ice inside the parent asteroid melted and reacted with dust, forming the minerals that now make up about 80% of Bennu. Certain ...
