Recently, a team of researchers (with the help of the National
Science Foundation’s (NSF) Very Long Baseline Array (VLBA) and a
host of international telescope partners) have managed to get
the clearest observation yet of the “core” of a black hole. A
black hole is a region of space in which the gravitational field
is so powerful that nothing, not even light, can escape its pull
after having fallen past its event horizon.From what they could
observe, astronomers drew the conclusion that there is a strong
evidence of enormous jets of particles emitted by supermassive
black holes, which are in fact corkscrewed in a way predicted by
theory. The researchers reported their findings in the April 24
issue of Nature. Also, they believe that the coiling is a result
of twisted magnetic fields acting on the particle streams. The
black hole was in the BL Lacertae galaxy, which 950 million
light years from Earth.
