June 7, 2005: A violent and chaotic-looking mass of gas and dust is seen in this Hubble Space Telescope image of a nearby supernova remnant. Denoted N 63A, the object is the remains of a massive star that exploded, spewing its gaseous layers out into an already turbulent region.See the rest:
Visible from the southern hemisphere, the LMC is an irregular galaxy lying 160,000 light-years from our own Milky Way galaxy in the direction of the constellation Dorado. The supernova remnant, N63A, is enclosed within the star-forming region, N 63, which itself is located in the large super bubble, LMC-4.
It is estimated that the progenitor of the supernova that produced the remnant seen here was about 50 times more massive than our own Sun. Such a massive star has strong stellar winds that can clear away its ambient medium, forming a wind-blown bubble. The supernova that formed N 63A is thought to have exploded inside the central cavity of such a wind-blown bubble, which was itself embedded in a clumpy portion of the LMC's interstellar medium.
The LMC provides excellent examples of active star formation and supernova remnants. Images in the infrared, X-ray, and radio emission of N 63A show a much more expanded bubble that totally encompasses the optical emission seen by Hubble. As the HST images have illustrated, N 63A is still young and its ruthless shocks are destroying ambient gas clouds, rather than coercing them to collapse and form stars. In a few million years, the supernova ejecta from N 63A will reach nearby star-formation sites and may be incorporated into the formation of planets around solar-type stars there.
