At the ragged frontier where the Sun’s influence gives way to the galaxy, a decades‑old spacecraft has stumbled into a ...

Scientists have discovered that our entire solar system is racing through the Milky Way far faster than current models predict. A study published in Physical Review Letters on November 10, 2025, ...

A monumental collision strong enough to jolt Uranus off its rotational plane and forever change the planet's behavior could explain one of the long-standing mysteries about the oddly-tilted ice giant.

As recently as two decades ago, we thought our solar system was “normal.” That was pretty accurate as long as you didn’t look at it too closely. But now we know our system has some remarkable ...
