"Its occurrence is like finding a tropical seed in Arctic ice – indicating either an unexpected local environment or ...

A new gas giant world discovered by citizen scientists using data from NASA's exoplanet-hunting spacecraft TESS is cool, ...

What can Earth-sized exoplanets teach scientists about the formation and evolution of exoplanets throughout the cosmos? This is what a study recently posted to the arXiv preprint server hopes to ...

Researchers mapped a pulsing mantle plume under Afar that channels molten rock upward, stretching Africa’s crust until it cracks and an ocean basin begins.

James Webb’s mid-infrared vision has likely captured a frigid, Saturn-mass planet shaping the dusty rings around the nearby ...

A rare Jupiter-sized planet AT2021uey b was found 3,200 light-years away using microlensing, a method based on Einstein's ...

Astronomers using ALMA have uncovered how gas and dust in planet-forming disks evolve separately an insight that reshapes our understanding of how different types of planets form. While dust lingers, ...

For the dwarf planet candidate, one trip around the sun takes over 24,000 years. Its orbit challenges a proposed path for a hypothetical Planet Nine.

The chance of a planet forming in the outer reaches of the solar system – a hypothetical Planet Nine – could be as high as 40 per cent, but it would have been a rough start ...

For years, astronomers have been searching for a ninth planet in our solar system (after giving Pluto the old heave-ho and demoting it to a dwarf planet) and now researchers say they’ve found a ...

Astronomers engaged in the search for a hypothetical ninth planet in our solar system have identified a promising candidate situated well beyond Neptune, according to a recent preprint study. This ...

The hunt for Planet Nine—the solar system’s ghostly gravitational troll—is longstanding, and is based on the peculiar clustering of rocky bodies in the Kuiper Belt beyond the orbit of Neptune.
