Behold: the final stage in the evolution of a star similar to our sun…also known as a planetary nebula.

Glowing like a multifaceted jewel, this nebula will gradually disperse into space over the next several thousand years, and then the star will cool and fade away for billions of years as a white dwarf. Our own sun is expected to undergo a similar fate, but fortunately, this will not occur until some 5 billion years from now. Credit: NASA/The Hubble Heritage Team (STScI/AURA)

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
