As the Earth moves through space, it is trailed by its own magnetic field. These magnetic field lines, or magnetotails, can sometimes get tangled—which can trigger an explosion. These bursts are only a fraction of a second long, but they can scatter millions of electrons at supersonic speeds. Learning about space explosions around Earth can also help us understand space explosions across the universe! Discover more: https://go.nasa.gov/2qVsrmt

An uncrewed Russian cargo ship linked up with the International Space Station Sunday (Nov. 18) to deliver nearly 3 tons of supplies for the orbiting lab.
The resupply ship, called Progress 71, docked at the space station at 2:28 p.m. EST (1928 GMT) as both spacecraft sailed 252 miles (405 kilometers) over Algeria. Progress 71 launched into orbit Friday (Nov. 16) from Baikonur Cosmodrome in Kazakhstan.
“A textbook journey for the Progress,” NASA spokesperson Rob Navias said during live commentary. [The Space Station’s Robotic Cargo Ship Fleet in Pictures].
