Solar winds are no threat to people on Earth, but can pose a danger to astronauts and spacecraft. NASA has selected two new missions that aims to better our understanding of how the Sun drives extreme space weather. The first mission, Polarimeter to Unify the Corona and Heliosphere (or PUNCH) will consist of four suitcase-shaped satellites that will track solar wind as it leaves the sun. The second, Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites (or TRACERS) will use two spacecraft to study how magnetic fields around Earth interact with the Sun.
This incredible image shows a pair of “nuclear superbubbles,” one over 4,900 light-years across and the other over 3,500 light-years. They’re emanating from the center of the galaxy NGC 3079, likely the result of a central black hole consuming matter and spewing it back out.
