New Horizons

An ethereal track by Queen lead guitarist Brian May accompanies the awe-inspiring time-lapse view from NASA's New Horizons flyby of a distant solar system object.

The New Horizons spacecraft is speeding away from its recent flyby target, a distant icy space rock nicknamed Ultima Thule, but the view from Earth is only getting better.

The best-ever photos of Ultima Thule have made it down to Earth, and they heighten the intrigue about the frigid and faraway world.

The final photos that NASA's New Horizons spacecraft snapped of Ultima Thule during the probe's epic Jan. 1 flyby reveal the distant object to be much flatter than scientists had thought.

The distant object Ultima Thule spins into view in a dramatic new video captured by NASA's New Horizons spacecraft.

Kuiper Belt objects like the one New Horizons just flew past are a dime a dozen, but scientists have detailed spacecraft observations of just three such distant, frozen worlds.

The most distant celestial object ever explored may well have moons, and astronomers are trying hard to find them.
