💫SNR 0543-689 in the LMC


The Tarantula Nebula (also designated 30 Doradus) owes its name to the arrangement of its brightest patches of nebulosity that somewhat resemble the legs of a spider. They extend from a central "body" where a cluster of hot stars (designated "R136") resides that illuminate the nebula. This name, of the biggest spiders on the Earth, is also very fitting in view of the gigantic proportions of the celestial nebula - it measures nearly 1,000 light years across! While the central regions of 30 Doradus may be compared to a tarantula, the entangled filaments in the outskirts of this nebula could well be likened with its cobweb. They testify to an ongoing history of very vigorous activity and make this spectacular sky region a showcase of dramatic effects caused by the tremendous output of energy from the most massive stars known. This is a bright, compact nebula that is located on the North-Western rim of the ringshaped nebula DEM L 299. It is known as SNR 0543-689 and it is the remnant of a more recent supernova explosion. The sky field measures 3.6 x 3.5 arcmin. North is up and East is left.
