In this picture you can see this huge 2-million light-year long galactic emission that is about 20 times the size of our galaxy. It is really amazing how big and how odd shaped this galactic emission is. It looks something like a jet afterburner pattern, a very large one.
The galactic emission is traveling just about at the speed of light and formed about 6 million years ago. It shines very brightly and has about as much power as 10 trillion suns! They call the object PKS 0637-752 and you can check out the fact sheet here. The emission is in a galaxy that is thought to be in its early stages of development and has a massive blackhole in the center. All the gases and space dust spin around this blackhole to form the galaxy somewhat like water going down a drain. This extremely fast spinning charges particles and causes them to emit a massive amount of radiation.
CSIRO Australia Telescope Compact Array radio telescope took images that show the radio wavelengths of this galactic emission. When examining the images astronomers where intrigued by something that looked like dots in the emission. These dots are called “knots” by astronomers and are not yet understod completely, but they represent pieces of this emission that are between 160,000 and 360,000 light-years each.
Its jet pattern is caused by the galactic emission turning off and on and a shockwave in the emission may be causing the “knots”. An explanation for this odd pattern is called shock diamonds. Astronomers will continue to research and find the correct explanation for this jet like shape. There has also been a research paper about this galactic emission.
