An active region on the Sun � an area of intense and complex magnetic fields � has rotated into view on the Sun and seems to be growing rather quickly in this video captured by NASA�s Solar Dynamics Observatory between July 5-11, 2017. Such sunspots are a common occurrence on the Sun, but are less frequent as we head toward solar minimum, which is the period of low solar activity during its regular approximately 11-year cycle. This sunspot is the first to appear after the Sun was spotless for two days, and it is the only sunspot group at this moment. Like freckles on the face of the Sun, they appear to be small features, but size is relative: The dark core of this sunspot is actually larger than Earth.

Measuring in at 10,159 miles (16,350 kilometers) in width (as of April 3, 2017) Jupiters Great Red Spot is 1.3 times as wide as Earth. This composite image was generated by combining NASA imagery of Earth with an image of Jupiter taken by astronomer Christopher Go.

Expedition 52 Flight Engineer Jack Fischer of NASA photographed the glowing nighttime lights of an aurora from his vantage point in the International Space Stations cupola module on June 19, 2017. Part of the stations solar array is also visible.

Backdropped by a blue and white Earth, the International Space Station is seen from Space Shuttle Discovery as the two spacecraft begin their relative separation. Earlier the STS-119 and Expedition 18 crews concluded 9 days, 20 hours and 10 minutes of cooperative work onboard the shuttle and station. Undocking of the two spacecraft occurred at 2:53 p.m. (CDT) on March 25, 2009.

NASA astronaut Jack Fischer photographed the SpaceX Dragon capsule as it reentered Earths atmosphere before splashing down in the Pacific Ocean west of Baja California at 8:12 a.m. EDT, July 3, 2017. Fischer commented, "Beautiful expanse of stars-but the �long� orange one is SpaceX-11 reentering! Congrats team for a successful splashdown & great mission!"

A variety of technological and biological studies conducted on the International Space Station are returning in Dragon. The Fruit Fly Lab-02 experiment seeks to better understand the effects of prolonged exposure to microgravity on the heart. Samples from the Systemic Therapy of NELL-1 for osteoporosis will return as part of an investigation using rodents as models to test a new drug that can both rebuild bone and block further bone loss, improving crew health. The Cardiac Stem Cells experiment investigated how microgravity affects stem cells and the factors that govern stem cell activity.

The Dragon spacecraft launched June 3 on a SpaceX Falcon 9 rocket from historic Launch Complex 39A at NASA�s Kennedy Space Center in Florida, and arrived at the station June 5.
