『SN 1987A 模擬実験』 [科学]

Using computer simulations astronomers can visualise the development of the supernova 1987A, from its initial blast observed three decades ago to the luminous ring of material seen today: The sequence begins with the star before it exploded. A ring of material was expelled about 20 000 years before the actual supernova happened. A flash of light indicates the actual stellar explosion which sends a shock wave outwards. As this wave slams into the ring, knots of dense material become intensely heated and glow brightly, while was with lower density is blown outward.

『SN 1987Aにズーム』 [科学]

This video starts with a view of the night sky as seen from the ground and zooms in onto the Large Magellanic Cloud, a satellite galaxy of the Milky Way. A further zoom shows the remnants of the supernova explosion 1987A, nestled between red-coloured gas, as they are seen by Hubble. The site of the supernova is surrounded by a ring of material that is illuminated by a wave of energy from the outburst. Two faint outer rings are also visible. All three of these rings existed before the explosion.

『SN 1987Aとリング』 [科学]

This time-lapse video sequence, created of images taken with the NASA/ESA Hubble Space Telescope, reveals the dramatic changes in the ring of material around the supernova 1987A.

The images, taken between 1994 to 2016, show the movement of debris from the supernova within the ring. The ring, about one light-year across, also begins to brighten as the shock wave of material hits it.
