Earth-Space Telescope System Produces Hot Surprise
Earth-Space Telescope System Hot Surprise
2016/4/13
Astronomers using an orbiting radio telescope in conjunction with four ground-based radio telescopes have achieved the highest resolution, or ability to discern fine detail, of any astronomical observ...
Event Horizon Telescope Reveals Magnetic Fields at Milky Way's Central Black Hole
Telescope Magnetic Fields Milky Way Central Black Hole
2015/12/14
Most people think of black holes as giant vacuum cleaners sucking in everything that gets too close. But the supermassive black holes at the centers of galaxies are more like cosmic engines, convertin...
