This morning at 10:36 a.m. EST, a SpaceX #Dragon cargo spacecraft left Earth carrying more than 4,800 pounds of research equipment, cargo and supplies that will support dozens of the more than 250 investigations aboard the International Space Station (@iss). This super science-heavy flight will deliver experiments and equipment that will study phenomena on the Sun, materials in microgravity, space junk and more. NASA astronauts Mark Vande Hei and Joe Acaba will use the space station’s robotic arm to capture Dragon when it arrives at the station early Sunday morning. Credit: NASA
Darker, cooler areas on the Sun – known as sunspots – have been absent for almost two weeks, as of Feb. 1.

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
