Smaller planets might be born when gas and dust is squeezed between larger worlds like the filling in a cosmic sandwich. The newly suggested process — dubbed "sandwiched planet formation" — would ...

The star system V1298 Tau reveals that many planets begin as large, low-density worlds that slowly shrink and shed their ...

Across the Milky Way, planets slightly larger than Earth but smaller than Neptune appear around most stars. Yet our own solar ...

When it comes to explaining how planets are formed, the protoplanetary hypothesis is the most widely accepted explanation. In simple terms, the donut-shaped disc of dust and gas around a star forms ...

BLOOMINGTON, Ind. — A new theory of how planets form finds havens of stability amid violent turbulence in the swirling gas that surrounds a young star. These protected areas are where planets can ...

Thanks to the discovery of thousands of exoplanets to date, we know that planets bigger than Earth but smaller than Neptune ...

The original version of this story appeared in Quanta Magazine. When Galileo Galilei, a mathematician at the University of Padua, trained a spyglass of his own creation on the sky, he was overwhelmed ...

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) found a young star surrounded by an astonishing mass of gas. The star, called 49 Ceti, is 40 million years old and ...

A radical new theory regarding the origin of the universe suggests that gravitational waves, tiny ripples in spacetime first predicted by Albert Einstein back in 1915, could have given rise to cosmic ...

Many of the stars in the Milky Way galaxy are small, dim red dwarfs—stars much smaller than the sun in both size and mass. TOI-6894, located far away from Earth, is one of them. Astronomers previously ...
