In Deep Oakland I led off the book with a chapter on the Hayward fault, the prime mover that continually makes our landscape. Yes, the Hayward fault is primed to give us a major earthquake. It's scary to think about. I said, "I know why people prefer not to think about the fault. Every time I visit it, no matter where, I push down the dread. But once I do that, there is room for wonder and interesting things to see."

Every year, stargazers convene for the "Messier Marathon" - a challenge to observe as many cosmic objects from the Messier catalog as possible in a single night! This catalog was compiled in the 1700s by French astronomer Charles Messier, and features several ideal targets for backyard astronomers. No telescope? No problem! Stargaze from your screen with Hubble, as a suite of new Messier images are unveiled from March 14-21.

Patches of the Sun's surface often show strong magnetic fields. These fields can emerge within a matter of hours, and can decay slowly or quickly, sometimes over days, weeks, or even months. Thanks to a new study about these long-lived active regions, we now know much more about the patches where these strong magnetic fields take at least a month to decay.

As the former CEOs of two of the largest water utilities using water from the Colorado River, we have been deeply engaged in interstate and federal negotiations on the river for over 30 years. Those negotiations were tough, but the basin states ultimately reached agreement, including reducing California's use of water by 800,000 acre-feet and adopting the current set of operating rules for the federal reservoirs.
