In principle, cosmic-ray observations can provide detailed insights into the physical profile of a passing ICME. But despite ...

Our Sun’s outer atmosphere, the corona, is millions of degrees hotter than it should be, and no one knows why.

Groundbreaking advances in solar and space physics have provided key insights into the inner workings of the heliosphere, the vast protective bubble formed by the solar wind that extends from the Sun ...

Astrophysicists are mapping a vast, hidden structure in the gas around the Sun that behaves like a tunnel carved through interstellar space, potentially linking our solar system to distant stars.

Black holes about the size of a hydrogen atom could be careening through the solar system unnoticed. But their days of stealth may be numbered. Two teams of researchers propose methods to search for ...

Astronomers have revealed new research showing that millions of new solar system objects are likely to be detected by a brand-new facility, which is expected to come online later this year.

"If our solar system is indeed moving this fast, we need to question fundamental assumptions about the large-scale structure of the universe." When you purchase through links on our site, we may earn ...

Far from the Sun’s heat, orbiting the outer planets of the solar system, are moons with oceans of liquid water beneath their frozen surfaces. Keith Cooper finds out how planetary scientists are ...

The workings of our solar system are roughly the same now as they have been for millions of years. Moons circle their planets, the planets circle the sun, the sun’s magnetic fields and sunspots wax ...

The recent visit to our solar system by the interstellar object 3I/ATLAS has sparked speculation about whether it’s another ...
