Just months after discovering FarOut, the most distant known object in the Solar System, the same team of astronomers has detected the faint—but not yet confirmed—glimmerings of an object even farther away. Dubbed FarFarOut, the extreme dwarf planet is 13 billion miles away—a distance so far it takes nearly 20 hours for the Sun’s rays to reach it.

The Cassini space probe’s fatal plummet into Saturn has revealed that the gas giant’s innermost ring sheds icy showers of rain and organic molecules into the planet’s upper atmosphere at an incredible rate.
Jupiter’s magnetic field is profoundly different from that of all other known planets — it essentially has two magnetic south poles instead of just one, a new Nature studyfinds. Continue reading Jupiter’s magnetic field has two ‘south poles’
Scientists know of 750,000 or so asteroids and comets—and all of them are part of this fine solar system. That is, all of them but one. And as new research shows, it’s weird as hell.
Spoiler alert: The universe is flat. But there’s a lot of subtlety packed into that innocent-looking statement. What does it mean for a 3D object to be “flat”? How do we measure the shape of the universe anyway? Since the universe is flat, is that…it? Is there anything else interesting to say?
Oh yes, there is.
In recent months, there’s been growing evidence that Pluto is hiding a liquid water ocean beneath its frozen surface. New models by researchers at Brown University support this hypothesis, and take it one mind-boggling step further: Pluto’s ocean may be more than 100 kilometers (62 miles) deep.
