About Planetaria



Pluto backlit by the Sun, as seen by New Horizons in 2015

Planetaria (formerly The Meridiani Journal) is a chronicle of planetary exploration, both in our own Solar System and beyond. Many continuing discoveries, such as the geysers of Enceladus, the subsurface ocean of Europa, the methane rivers, lakes and seas of Titan, the mountains and glaciers of Pluto, the cold but beautiful deserts of Mars and the thousands of exoplanets orbiting other stars make this an exciting time of exploration and discovery.

I publish Planetaria as a personal blog, a complement to my other freelance space writing for EarthSky and AmericaSpace.
