Why should we care about the new findings - released this week - from NASA's Parker Solar Probe? This new NASA video explains how the solar wind - a stream of charged particles from the sun - affects earthly astronauts and technologies.

From ESA's Proba-2 satellite, images of the sun in January or February of each year from 2010 to 2019. This mosaic neatly shows the variability in the solar atmosphere in beautiful detail.

New research suggests that superflares - massive bursts of energy from a star's surface - can happen on stars like our sun. What might that mean for us on Earth?
