10 September 1987: A newly discovered quasar (eso8712) has been found to have a record redshift [1] of 4.11 and is therefore the hitherto most distant known object in the Universe.

13 May 1986: Detailed observations of a bright supernova in the peculiar galaxy NGC 5128 = Centaurus A, have led astronomers at the European Southern Observatory to believe that this galaxy is much closer to us than previously thought. It is the nearest, strongly radio-emitting galaxy and is as such an object of crucial importance in modern astrophysical research. The revised distance is 7 - 10 million light years or only 3 - 4 times farther away than the Andromeda Nebula. Cen A may therefore even be an outlying member of the Local Group. The total radio emission energy corresponds to the conversion to pure energy (annihilation) of a mass equal to 10.000 suns.
