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 ...

Scientists find that two hot stars passed near our solar system 4.4 million years ago, altering nearby interstellar clouds.

Our solar system is on the move, traveling at 828,000 km/h through a galactic structure most people don't know exists. This ...

Our solar system resides within a bubble of superheated gas known as the Local Hot Bubble (LHB). Scientists have long pondered its origins. To better study this region, the Max Planck Institute for ...

Nearly 4.5 million years ago, two enormous, blazing stars swung close to the solar system. They did not touch the sun, but ...

A tiny satellite circling Earth is providing an unexpectedly complicated picture of the solar system's heliosphere, the invisible bubble that extends far beyond the planetary orbits to where the solar ...

Nearly 4.5 million years ago, two large, hot stars brushed tantalizingly close to Earth's sun. They left behind a trace in ...

Around 4.4 million years ago—long before humans existed—two massive, blazing-hot stars swept past our solar system. They didn ...

Voyager 1 and 2 traveled billions of miles to reach the heliopause, showing how the Sun's magnetic influence marks the boundary of our solar system.

For decades, astronomers have detected an unusual mix of ionised gas in the local clouds. Roughly 20% of hydrogen and 40% of ...

Scientists have been able to recreate the extreme conditions found on icy moons in deep space - and revealed the unstable behaviour of water. In the near-zero pressure environment of space, water ...
