Description

More from Chile! Some of the only data I got on a telescope due to some mount power issues.
I didn't want to add one-time-use-only hardware to my already inflated hardware list, so here's the goods:
Mount: Sky-Watcher AZEQ6
Telescope: Takahashi FSQ-85ED
No guiding

Centaurus A is a peculiar galaxy somewhere between 10-16 million lightyears away (so pretty close to us). It's also known as the Hamburger Galaxy, which is more obvious when viewing visually! It doesn't fit cleanly into one of the established categories of galaxies, and it's also a very bright radio source due to its active galactic nucleus. Its odd shape is likely the result of a galactic collision. At the center of this galaxy is a 56-million-solar-mass black hole that is blasting out jets of gas that emit strongly in x-ray and radio. Closer to the origin, the gas in the jet is moving as fast as half the speed of light! Plus, the radio-emitting cooler gas further out in the jet extends out as far as a million lightyears.
