Using data from the eROSITA All-Sky Survey, astronomers have created a 3D map of the low-density bubble of X-ray-emitting, million-degree hot gas that surrounds the solar system. The investigation has ...

When the object now known as 3I/ATLAS was flagged by automated sky surveys, it first looked like another distant icy body ...

Did you know our entire Solar System is cocooned inside a giant protective bubble, known as the heliosphere? Created by the perpetual outflow of charged particles from the Sun, called the solar wind, ...

Exoplanets are planets outside Earth's solar system that most often orbit a star. Astronomers have managed to bring an exoplanet into unprecedented focus by using a technique the researchers call 3D ...

An ancient comet discovered in our solar system this summer is offering a rare opportunity to learn more about distant planetary systems far beyond the reach of any spacecraft, researchers say. The ...

An interstellar object – a comet from a distant star system – is passing through the space between Jupiter and Mars, and according to a recent study, Comet 3I/Atlas may be 3 billion years older than ...

Only four such objects have been discovered, astronomers say. Astronomers have discovered a "fossil" body residing on the outskirts of the solar system, according to new research. The object – which ...
