- Seattle is the largest city in Washington state and its economic capital. Settled in 1851, its deep harbor and acquisition of Puget Sound’s first steam-powered sawmill quickly established it as a center of trade and industry. It gained the Territorial University (now University of Washington) in 1861, but was snubbed by the Northern Pacific Railroad in 1874 when it picked Tacoma as its western terminus. Despite this, the town prospered thanks to independent railroad development fueled by local coal deposits…
- Astronomers Unveil Strong Magnetic Fields Spiraling at the Edge of Milky Way’s Central Black Hole (eventhorizontelescope.org)
A new image from the Event Horizon Telescope (EHT) collaboration has uncovered strong and organized magnetic fields spiraling from the edge of the supermassive black hole Sagittarius A* (Sgr A*). 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*. The results were published today in The Astrophysical Journal Letters.
