When Hurricane Harvey blows ashore over coastal Texas on Friday, it will likely be the first major hurricane to make landfall in the United States since 2005. The Moderate Resolution Imaging Spectroradiometer (MODIS) on our Terra satellite captured this natural-color image of the rapidly intensifying storm at 12:24 p.m. EDT on Aug. 24.

A single, tiny one appeared on Jan. 31, but even that is hard to see in this rotating view from our Solar Dynamics Observatory. The video shows a rotating sun in filtered light for the past week, but it is even hard to tell the sun is rotating since there are just about no features. This spotless period is a prelude to the approaching period of solar minimum next year, when the Sun’s activity will be at the low end of its 11-year cycle. Credit: NASA/SDO
