‘The details of this transition will give astronomers a better understanding of the life of the doomed star, and how it ended,’ said Kari Frank of Penn State University who led the latest Chandra study of SN 1987A. Now, the central structure inside the ring in the Hubble image has grown to roughly half a light-year across.

Enter the Space & Beyond Box Photo Contest! Dans cette simulation en trois dimensions réalisée par la Nasa, on peut voir ce qui s'est passé dans l'environnement très proche de la supernova 1987A depuis son explosion, observée sur Terre le 23 février 1987. Small blobs of gas that were disconnected from other blobs or from the ring were removed from the model using 3D animation software for ease of printing. These observations also suggest that dust in the early universe likely formed from similar supernova explosions. Yet. Using the Ultimaker 3 printer with dissolvable supports at 0.1 mm resolution this model took about 40 hours to print. - Read the brief instructions below The series of data released by NASA includes breathtaking images, time-lapse movies, and a 3D model, providing an unprecedented glimpse at Supernova 1987A. A flash of light depicts the supernova explosion, followed by expansion of the subsequent blast wave. To complicate matters, astronomers suspect the supernova explosion itself was possibly not symmetric, but instead sent more energy in one direction than others, exaggerating the nonspherical shape of the remnant we see. This video shows a visualization of SN 1987A and the evolution of the resulting supernova remnant up until the present day.
The supernova was first spotted on February 23, 1987. A flash of ultraviolet light from the explosion energized the gas in the ring, making it glow for decades.The central structure visible inside the ring in the Hubble image has now grown to roughly half a light-year across. View our Privacy Policy. These changes provide evidence that the explosion's blast wave has moved beyond the ring into a region with less dense gas. Additionally, it required about an hour of finish work with needle-nose pliers and similar tools to remove the support structures manually. Astronomers also are still looking for evidence of a black hole or a neutron star left behind by the blast. Vue la distance, ces évènements se sont produits il y a 168.000 ans.

À raison de 4 années par seconde, cette vidéo de la Nasa montre l'explosion de la supernova découverte en 1987 et suivie depuis 30 ans.
One frame is shown per year and the visualization steps between them at four years per second. Learn how to print your own 3D copies of SN87A, 3D files (Ring Debris 2017 - Ring 2017 - Combined), Coding & Astronomy Celestron celebrates 60 years of crafting telescopes.

Ainsi, tout au long des 30 années écoulées les chercheurs ont pu voir l'embrasement progressif de cette couronne à mesure que les vents ont déferlé sur elle. Over the many years of observations, these telescopes have seen the initial powerful explosion morph into the heated debris field that hurtles the remains of the star outward into space.
