This journey through a dense region of space could have compressed the heliosphere, the protective bubble surrounding our solar system, and increased the influx of interstellar dust, potentially ...

Our solar system has always seemed a vast place, even to the most ancient astronomers who knew little of the universe other than what the sun, moon, and stars could reveal to the naked eye.

A giant wave of undulating gas and dust appears, per new research, to have engulfed our Solar System millions of years ago. Now, University of Vienna doctoral student Efrem Maconi thinks that our ...

Beyond Neptune, a crowd of frozen bits and pieces lingers in the Kuiper Belt, yet that is only the start of our Sun’s extended family. Farther out – about 9.3 trillion miles away – sits the Oort Cloud ...

Our sun belongs to a spiraling galaxy filled with star-forming neighborhoods. Astronomers recently found that our entire solar system traveled through a dense region in the constellation Orion about ...

And tantalizingly, what they found suggests that our solar system may already be flooded with visitors from the star system, which is about 4.25 light years away. These objects range from ...

The mysterious Oort cloud is the source of many of our solar system's comets, but astronomers still have no idea what it looks like. Now, new simulations may have given them a first glimpse.

11, 2025 — A new study presents a compelling new model for the formation of super-Earths and mini-Neptunes -- planets that are 1 to 4 times the size of Earth and among the most common in our galaxy.

At the edge of our solar system, a host of large, icy bodies make up the Oort cloud, which appears to sport two spiral arms reminiscent of a disk-shaped galaxy. New research founded upon a simulation ...

This journey through a dense region of space could have compressed the heliosphere, the protective bubble surrounding our solar system, and increased the influx of interstellar dust, potentially ...

The SPHEREx telescope will create the most colorful map of the cosmos, while the four satellites of the PUNCH mission track ...

Every Planet of Our Solar System Is Lining up in the February Night Sky NEW YORK (AP) — Seven planets grace the sky at the end of February in what's known as a planetary parade, though some will ...
