Researchers have discovered that a two-step formation process of the early Solar System can explain the chronology and split in volatile and isotope content of the inner and outer Solar System. An ...

Jan. 21 (UPI) --The solar system features a unique dichotomy of planets -- the inner solar system features smaller, drier bodies, while the planets found in the outer solar system are larger and ...

If you want to build a planet, you're going to have to get your hands dirty. That's the lesson from a recent paper, which outlines just how vital giant impacts are to the formation of planets.

New work from Carnegie’s Alan Boss and Sandra Keiser provides surprising new details about the trigger that may have started the earliest phases of planet formation in our solar system. It is ...

Short-lived radioisotopes such as aluminum-26 influenced early solar system heat, water retention and the formation of Earth-like rocky planets, according to meteorite analyses and models.

The Japan Aerospace Exploration Agency's Hayabusa2 mission returned uncontaminated primitive asteroid samples to Earth. A comprehensive analysis of 16 particles from the asteroid Ryugu revealed many ...

Compared to the rest of the universe, our solar system is just a teenager — it formed 4.5 billion years ago compared to the universe’s 13.8 billion years. But more shocking is how quickly our entire ...

An international team of astronomers including Stella Offner of The University of Texas at Austin has proposed a new method for the formation of aluminum-26 in star systems that are forming planets.

Everything we know about the formation of solar systems might be wrong, says University of Florida astronomy professor Jian Ge and his postdoc, Bo Ma. They’ve discovered the first “binary-binary” – ...

Deep near-infrared color composite image of the L1688 cloud in the Ophiuchus star-forming complex from the VISIONS European Southern Observatory public survey, where blue, green and red are mapped to ...

An international team of researchers from the University of Oxford, LMU Munich, ETH Zurich, BGI Bayreuth, and the University of Zurich discovered that a two-step formation process of the early Solar ...
