Xi Zhang, a professor of Earth and planetary science at UC Santa Cruz, has discovered that an exoplanet classed as a “super-Jupiter” has substantial differences from our solar system’s largest planet — and in fact, has much in common with Mars. Exoplanet VHS 1256b, located 40 light years away from Earth, was identified in 2015.

The atmospheres of brown dwarfs can be surprisingly similar to those of gas giant planets, too, complete with multi-layered clouds and powerful wind-driven storms. That makes them great windows into the atmospheric processes that shape our own solar system’s giant planets, as well as the super-Jupiter exoplanets discovered outside our stellar neighborhood, according to a…

The James Webb Space Telescope (JWST) has discovered that a hazy sky over frozen Pluto is helping to cool the dwarf planet’s atmosphere. The discovery of the haze was predicted back in 2017 by planetary scientist Xi Zhang of the University of California, Santa Cruz, to explain why Pluto’s thin atmosphere is so leaky. Additional…

After New Horizons’ Pluto flyby, UC Santa Cruz‘s Xi Zhang proposed in 2017 that Pluto’s atmosphere is dominated by haze particles, making it unlike any other in the solar system. He suggested that these particles heat up and cool down, controlling Pluto’s entire energy balance.
