Chinese and Japanese astronomers recorded the rare event, an explosion of a star, or supernova. Now, astronomers have mapped the location and speed of those unusual filaments in three dimensions for the first time.

Now, thanks to a lucky line up of two spacecraft currently in space studying the Sun, they may have discovered the answer.

Seen in polarized light for the first time, this new view of the monster lurking at the heart of the Milky Way Galaxy has revealed a magnetic field structure strikingly similar to that of the black hole at the center of the M87 galaxy, suggesting that strong magnetic fields may be common to all black holes. This similarity also hints toward a hidden jet in Sgr A*.
