Astronomers discover a strange spiral galaxy

A strange galaxy called J1649+2635, nearly 800 million light-years from Earth, has astronomers scratching their heads … but in a good way. 

Like our Milky Way, it’s a spiral galaxy, and it’s the most recent of only four known galaxies with prominent jets of subatomic particles propelled outward from its core at nearly light speed. 

The mystery is that spiral galaxies aren’t supposed to have such large jets. It took a combined effort of astronomers and citizen scientists to discover J1649+2635 and shed light on the mystery.

According to a December 2, 2014 press release from The National Radio Astronomy Observatory (NRAO), the first spiral galaxy with a jet was found in 2003. The second was found in 2011, and the third was found earlier this year. All three spiral galaxies with jets were discovered by combining radio and visible-light images.

But how did the observatory team figure out? Read about the discovery here.
