Within Pluto's informally named Vega Terra region is a field of eye-catching craters that looks like a cluster of bright halos scattered across a dark landscape.

Pluto's haze varies in brightness

Scientists on NASA's New Horizons mission team are learning more about the structure and behavior of Pluto's complex atmosphere by discovering new attributes of its extensive haze layers. The hazes were first discovered by ...

The hot problem of black hole firewalls

For the last four years, physicists studying the mathematical underpinnings of black holes have been wrestling with a strange idea: that black holes contain a region known as a "firewall," which utterly annihilates matter ...

Image: Computer simulation of a supermassive black hole

This computer-simulated image shows a supermassive black hole at the core of a galaxy. The black region in the center represents the black hole's event horizon, where no light can escape the massive object's gravitational ...

New Horizons fills gap in space environment observations

When NASA's New Horizons sped past Pluto on July 14, 2015, it took the best-ever pictures of the rocky world s surface, giving us new insight into its geology, composition and atmosphere. These stunning images are the most ...

Image: Pluto's bladed terrain in 3-D

One of the strangest landforms spotted by NASA's New Horizons spacecraft when it flew past Pluto last July was the "bladed" terrain just east of Tombaugh Regio, the informal name given to Pluto's large heart-shaped surface ...

New Horizons imagery reveals small, frozen lake on Pluto

NASA's New Horizons spacecraft spied several features on Pluto that offer evidence of a time millions or billions of years ago when – thanks to much higher pressure in Pluto's atmosphere and warmer conditions on the surface ...

Ancient Pluto may have had lakes and rivers of nitrogen

The New Horizons probe revealed the surface features of Pluto in rich detail when it reached the dwarf planet in July 2015. Some of the features look like snapshots of rivers and lakes that are locked firmly in place by Pluto's ...
