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.

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 ...

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

The solar system is meant to be a familiar place, a cosmic neighbourhood defined by predictable, elliptical paths. Yet, every ...

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

Guest: Professor Dagomar Degroot, environmental historian at Georgetown University and author of Ripples on the Cosmic Ocean: ...

Astronomers from Keele University in the UK have utilized NASA's planet-hunting TESS telescope to investigate a ...

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 ...

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 ...
