The origin of super-Earths and sub-Neptunes has been revealed in a system of four young planets that are dramatically losing ...

Korean researchers have uncovered the secret to how planets and comets could form far from a star — considered a mystery until now — by finding the key in a substance named crystalline silicates as ...

Thanks to the discovery of thousands of exoplanets to date, we know that planets bigger than Earth but smaller than Neptune orbit most stars. Oddly, our sun lacks such a planet. That's been a source ...

Most planetary systems contain worlds larger than Earth but smaller than Neptune, and the low-density planets around one young star should help us understand how such systems form ...

For decades, scientists have studied how planets form by looking at young stars nearby, assuming that these environments could be representative of all star systems. However, as astronomers discover ...

A new study led by UNLV scientists sheds light on how planets, including Earth, formed in our galaxy – and why the life and death of nearby stars are an important piece of the puzzle. In a paper ...

New research tracks young planets around a nearby star, showing how large, gas-rich worlds shrink over time to become the most common planets in the galaxy ...

How did a planet this big form around a star this small? An international team of astronomers, including researchers from the University of Liège and collaborators in UK, Chile, the USA, and Europe, ...
