Pluto is hazy, with a chance of clouds.

Scientists working with data from NASA’s New Horizons spacecraft, which flew past Pluto last year, are presenting some of their latest results this week in Pasadena, Calif., at a meeting of the American Astronomical Society’s Division for Planetary Sciences.

The findings include images showing seven small, bright spots that might be clouds floating just above Pluto’s surface.

New Horizons had already discovered haze in Pluto’s tenuous atmosphere, rising more than 120 miles into the sky and separated into at least 24 distinct layers.
