Hurricane Irma formed in the Atlantic Ocean and has affected the Caribbean, including Puerto Rico and the U.S. Virgin Islands, before impacting the United States. Our fleet of satellites have been continually providing forecasters with data on Hurricane Irma. That includes satellite imagery for Irma, plus trajectory, force and precipitation tracking to inform the National Hurricane Center. Image Credit: NASA

Rhea is a heavily-cratered, airless world, while Titan’s nitrogen-rich atmosphere is even thicker than Earth’s. This natural color image was taken in visible light by the Cassini spacecraft on Nov. 19, 2009, at a distance of approximately 713,300 miles (1,148,000 kilometers) from Rhea. After a nearly 20-year mission that overflowed with discoveries, the Cassini spacecraft ended its mission on Sept. 15, 2017. Credit: NASA/JPL-Caltech/Space Science Institute
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
