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

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 ...

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 ...

The NASA/ESA/CSA James Webb Space Telescope has provided the first direct measurements of the chemical and physical ...

The JWST has studied the chemical composition of a moon-forming disk circling a giant planet 625 light-years away.

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

Exoplanet hunters Christopher Watson and Annelies Mortier explain the long search for a 'twin Earth' capable of sustaining ...

There are 8 planets in our solar system. The planets orbit the Sun in elliptical trajectories, and they are all different in size, composition, temperature, and characteristics. The planets can be ...

Thirty years ago, on a crisp October day in 1995, two Swiss astronomers changed the course of cosmic history. Michel Mayor ...

Imagine a massive celestial body colliding with Uranus at high speed; this impact could have 'overturned' Uranus, causing its rotation axis to tilt. Moreover, the colliding body would have to be ...

A planetary conjunction is an astronomical event in which at least two planets – sometimes more – appear to our vantage from Earth to be close together in the sky. Both Venus and Jupiter are making ...

For millions of years, a fragment of ice and dust drifted between the stars—like a sealed bottle cast into the cosmic ocean.
