As the first supernova visible to the naked eye in about 400 years, Supernova 1987A (or SN 1987A for short) sparked great excitement among scientists and soon became one of the most studied objects in the sky.

The supernova is located in the Large Magellanic Cloud, a small companion galaxy to our own Milky Way, only about 170,000 light-years from Earth.

While astronomers watched debris explode outward from the site of the detonation, they also looked for what should have remained of the star's core: a neutron star.

Supernova 1987A exploded more than 30 years ago and is still surrounded by debris.

The energetic environment has been imaged by NASA’s Nuclear Spectroscopic Telescope Array, or NuSTAR (shown in blue) and the Chandra X-ray Observatory (shown in red), which has finer resolution.

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.
