Prepare to look up and reconsider everything you thought you knew about these cosmic wanderers. Comet 3I/ATLAS has shattered ...

The object, discovered by Gennady Borisov on November 2, 2025, quickly became the focus of speculation amid the curiosity ...

An illustration of Mimas’s ice shell evolution, in which the changes in ice shell thickness (y-axis) lag behind the eccentricity decay (inverted x-axis). Time increases to the right of the plot, while ...

C/2025 V1 Borisov races toward the sun with 3I/ATLAS-style oddness. Discovery, orbit, expert quotes, and what to watch as astronomers seek answers.

A passing star which blew past our solar system nearly 3 million years ago could have altered the Earth’s orbit, researchers found. The study, published last week in the journal The Astrophysical ...

Professor John Chiang of UC Berkeley explains the impact of Earth's axial tilt and orbital eccentricity on global climate. He highlights their influence on seasonal variations, including monsoon ...

This paper describes the eccentricity, amplitude, phase shift, angular momentum, polarization, radial path, and orbital ...

This artist’s impression shows a Jupiter-like exoplanet that is on its way to becoming a hot Jupiter — a large, Jupiter-like exoplanet that orbits very close to its star. NOIRLab/NSF/AURA/J. da Silva ...

The Paleocene-Eocene Thermal Maximum (PETM), a period of rapid warming 56 million years ago, saw temperatures increase by approximately 5 degrees Celsius over a few thousand years, resulting in ...
