where is planet nine hiding? and does it actually exist?

Yet another study promising to help us find a planet beyond the orbit of Pluto fails. So, where exactly is Planet Nine? And why haven't we found it?

why planet nine may not actually exist

Astronomers looking into the orbits of Kuiper Belt objects may have found a flaw in data we thought pointed to the existence of a large planet beyond Neptune's orbit.

a planet four times the size of its star shows how solar systems die

When some stars die, they take their entire systems with them. Others appear to give their planets a fighting chance.

how jupiter may have moved it, moved it from the outer reaches of the solar system

Considering what we know about planetary formation, Jupiter shouldn't have been able to grow as massive in its current orbit. But a new simulation shows it could've been born much, much further away.

astronomers find a fossil from the early days of the solar system

A tiny, roughly kilometer sized rock might not seem like much of a discovery, but it's an important confirmation of our models of planetary formation and solar system evolution.

why the hunt for planet nine is still underway

A recent paper imagines a new explanation for the strange motions of Trans-Neptunian Objects observed by astronomers for the last 200 years, but it doesn't mean that we won't still search for Planet Nine.

yes, uranus got wrecked but that's not even the half of it

A massive collision seems to be the only plausible reason why Uranus is the oddball it is, and now we have an idea of what it might have looked like. So what do we do with this data?

why saturn's majestic rings won't be around for much longer

Saturn's rings are young and might be gone almost as quickly as they appeared in planetary terms, according to the latest research by NASA.

the fun, excitement, and challenge of recording alien winds

InSight's recording of Martian winds isn't what you'd hear if you were on the planet yourself. And if you start asking why, you'll find out some bizarre and fascinating things about how winds work on alien worlds.

hey, what's a world like you doing in a solar system like this?

The debate over whether Pluto is a planet, much less what constitutes a planet, is still raging in the scientific community.

when simulations and the media collide

Despite what the media might have told you, we don't actually know if a rocky planet slammed into Jupiter or not.
