The Heart of Draco the Radio Galaxy 3C 305
Description
Telescopes that allow scientists to study the Universe at radio, optical, and X-ray wavelengths were used to create this intriguing image of the radio galaxy, 3C 305, which is located in the constellation of Draco the Dragon. The radio data (blue) were acquired at a wavelength of 21 cm with the NRAO Very Large Array and with the Multi-Element Radio-Linked Interferometer Network (MERLIN) operated by the Jodrell Bank Observatory. The images at optical and X-ray wavelengths were obtained with the Hubble Space Telescope (cyan) and Chandra X-ray Observatory (red), respectively. Note that the radio emission is not directly connected with that of the X-rays, while the optical emission seems to be associated with the high-energy X-ray emission.
