Pluto imparted a slight but measurable alteration to the New Horizons spacecraft's trajectory (both bending and acceleration) during its 2015 flyby. The minimal nature of this trajectory change was ...

Scientists are starting to get a clearer picture of how Pluto’s strange, hazy atmosphere works. Their latest discovery, concerning waves rippling through the dwarf planet's atmosphere, means that ...

Pluto might have hogged much of the spotlight historically, but the dwarf planet is actually part of a double act, alongside its biggest satellite, Charon. A new analysis suggests that Pluto used its ...

In late August 2006, new discoveries upended a traditional, comfortable way of viewing our solar system: Scientists decided Pluto wasn’t a planet after all. Some space nerds like to mourn Pluto’s loss ...

What will our solar system look like after the Sun dies? This is what a recent study published in the Monthly Notices of the Royal Astronomical Society hopes to address as a team of scientists ...

In 2015, NASA’s New Horizons probe flew by Pluto as it orbited the Sun in the solar system’s Kuiper Belt. New Horizons captured seminal images of the dwarf planet, including many highlighting one of ...

Imagine throwing a baseball. Easy, right? Maybe you've already done it a few times. Now imagine throwing a baseball on the moon. Maybe you've seen enough videos of astronauts bouncing around up there ...

Watch a ball throw on each planet in our solar system, plus Pluto and the moon, below. Imagine throwing a baseball. Easy, right? Maybe you've already done it a few times. Now imagine throwing a ...

This one comes from SnowGhost's question about the lack of impact craters on Pluto and allowed me to use one of the most unlikely titles you're ever going to see in the physical sciences. Pluto is not ...

On far-flung Pluto, it may be raining moon dust. Models suggest that Pluto’s small moons are even now sprinkling dust on its equator, which could explain why Pluto’s middle is darker than its poles. A ...

In the hope of ending years of wrangling, a committee of astronomers and historians has proposed a new definition of the word "planet" that would expand at a stroke the family of planets from nine to ...

Maybe Pluto is a planet after all. The icy ball at the outer edge of the solar system was considered a planet from its discovery in 1930 until 2006, when a global astronomy organization made the ...
