Image of the Day - Mysterious Signals from Milky Way Galaxy's Centre

This is simulated image of mysterious Signals from Milky Way Galaxy's Centre. Astronomers have discovered unusual signals coming from the direction of the Milky Way’s centre. The signal has a very high polarisation. This means its light oscillates in only one direction, but that direction rotates with time. The brightness of the object also varies dramatically, and the signal switches on and off apparently at random. The radio waves fit no currently understood pattern of variable radio waves, like the signals from stars like pulsars, supernovae, flaring stars, and fast radio burst. This could suggest a new class of stellar objects. The discovery was made with ASKAP (Australian Square Kilometre Array Pathfinder Telescope) under a project called the Variables and Slow Transients (VAST) survey. Hence, the new and, as yet, unidentified object has been named ASKAP J173608.2-321635.
