Scientists have discovered tadpole-shaped jets coming out of regions with intense magnetic fields on the Sun. Unlike those living on Earth, these “tadpoles” – formally called pseudo-shocks – are made entirely of plasma, the electrically conducting material made of charged particles that account for an estimated 99% of the observable universe. The discovery adds a new clue to one of the longest-standing mysteries in astrophysics.

For 150 years scientists have been trying to figure out why the wispy upper atmosphere of the Sun – the corona is over 200 times hotter than the solar surface...

Hours before the rise of the very star it will study, NASA’s Parker Solar Probe launched from Florida Sunday to begin its journey to the Sun, where it will undertake a landmark mission. The spacecraft will transmit its first science observations in December, beginning a revolution in our understanding of the star that makes life on Earth possible.
