Researchers additionally used the Very Long Baseline Array (VLBA) and NASA's Chandra X-ray observatory to further observe the galaxy. Years of data were needed to confirm the finding because TXS 0128 is about 100,000 times less powerful than most of the other 3,000 active galaxies observed. Scientists have been studying the galaxy for about five years, after NASA's Fermi Gamma-ray Space Telescope reported that it is a source of gamma rays, the highest-energy form of light. The colors correspond to the radio signal's intensity, from low (purple) to high (yellow). This image shows TXS 0128 at 15.4 gigahertz as observed by the Very Long Baseline Array (VLBA), a globe-spanning network of radio antennas. Around one-tenth of active galaxies produce these jets - which appear in this case like the starfighter's wings - when gas and dust build and heat up due to gravitational and frictional forces.
