While coasting through the outer solar system, NASA's New Horizons is busying itself with astronomical observations of a distant Kuiper Belt Object.
As we approach the closest opposition with Mars in 10 years, Hubble took the opportunity to photograph the Red Planet's sun-lit hemisphere.
With so much space in outer space, it's tempting to think there's a whole lot of nothing between the big objects. But a closer look finds more than just dust in those voids.
The gas giant is known to be the target of some massive chunks of space debris, but now astronomers have a pretty good idea about how many big impacts can be seen from Earth.
A nearby star system has been discovered sporting its own Kuiper belt -- a region populated with ancient icy comets and asteroids.
Comet 252P/LINEAR buzzed Earth during one of the closest recorded cometary encounters with our planet and Hubble locked onto the icy vagabond as it ran away into the night, imaging its rotating tail.
A small water jet on the icy moon spews its fiercest eruptions when the moon is farthest from the planet, but overall gas output hardly increases.
Mark your calendars: The smallest planet in the solar system is about to make a REALLY big entrance.
