An Alternative Identification of the Radio Source in the Direction of the Galactic Centre

Naturevolume 175pages10791081 (1955) | Download Citation



A RADIO source the co-ordinates of which agree closely with those of the centre of the Galaxy has been reported by several observers, and it has been suggested that it may be identified with the nucleus of the Galaxy1–3. The galactic co-ordinates of this source are l = 327° and b = − 2°, and it is designated 1752A in the list recently published by the International Astronomical Union4. The apparent angular diameter of the source has been observed by Mills5 to lie between ½° and 1° at 100 Mc./s. An independent estimate made at Jodrell Bank at 1,420 Mc./s. indicates that the diameter is 1°.
