In any case, officials at the Jet Propulsion Lab in Pasadena say, it defies all known classifications. Each jet contains at least six bright clumps of gas speeding along at rates of at least 375,000 miles per hour. These clumps are ejected into space about every 100 years.
Young stars behave in a similar way.
Hubble astronomers believe the object is actually two aging stars masquerading as a single youngster. One may be a bloated red giant star shedding matter from its outer layers. This matter is then captured by gravity in a rotating accretion disk around a compact partner, most likely a young white dwarf, the collapsed remnant of a sun-like star, JPL scientists said. The disc-like structure is a mixture of matter and gases, the center of which is a growing young star, he said. Our solar system grew in similar fashion, he said.
