   When does solar activity stop?

   • “As we emerge from solar minimum and approach Cycle 25’s maximum, it is important to remember solar activity never stops; it changes form as the pendulum swings,” said Lika Guhathakurta, solar scientist at the Heliophysics Division at NASA Headquarters in Washington.

   Is this the first time a spacecraft flies through the Sun?

   • The US space agency (Nasa) is calling it a historic moment - the first time a spacecraft has flown through the outer atmosphere of the Sun. The feat was achieved by the Parker Solar Probe, which dipped, for just a short while, into a region around our star that scientists call the corona.

   Did a spacecraft touch the Sun?

   • The results have been published in Physical Review Letters and accepted for publication in the Astrophysical Journal. For the first time in history, a spacecraft has touched the Sun. NASA’s Parker Solar Probe has now flown through the Sun’s upper atmosphere – the corona – and sampled particles and magnetic fields there.

   What happens if the sun hits Earth?

   • The biggest outbursts from the Sun can rattle our planet's magnetic field. In the process, communications may be disrupted, satellites can be knocked offline, and power grids will be vulnerable to electrical surges. Scientists try to forecast these "storms" and Parker promises new and valuable information to help them do that.
