About SDO / SOHO Mission
The image is provided by NASA's Solar Dynamics Observatory (SDO). Launched in 2010, SDO monitors the Sun 24/7, providing data on its magnetic field and solar activity, helping scientists understand how the Sun affects space weather near Earth. Data is distributed in collaboration with the SOHO mission, which has been a cornerstone of solar physics since 1995.
Official SDO WebsiteEvolution & Future
The Sun is currently in a state of hydrostatic equilibrium on the main sequence. In about 5 billion years, after exhausting its hydrogen, the star will expand into a red giant, eventually ending its cycle as a white dwarf.
