I would like to direct readers to a couple of old Eos articles from 2016 that I found particularly engrossing.
The first is an article by JoAnna Wendel on dwarf planets. I vaguely remember Pluto being dethroned from the status of planets some 15 years ago, and placed into the category of dwarf planets. I remember agreeing with the reasoning, at the time, but didn't pay much attention to dwarf planets. Wendel's article made me realize that dwarf planets constitute a rich set of objects, integral to our solar system, and as worthy of attention as their big siblings.
The second article by Jeffrey J. Love and Pierdavide Coisson, is about a cluster of geomagnetic storms triggered by solar activity in September 1941, and their effects on the earth during WWII. There hasn't been such a cluster of geomagnetic within a single 14 hour period since then. Our civilization would be much more vulnerable now to such an event than we were then, but the article tells of several examples of how life on Earth was disrupted. It shows the importance of studying, and perhaps forecasting, space weather.
