Supernovas, or star explosions, release an intense burst of light in all directions. Rarely, from the original supernova<\/a> position, rings of light or “light echoes” spread out in the months and years that follow.<\/p>\n

As described in a recent paper based on observations made with the Hubble Space Telescope, astronomers were able to capture images of supernova light echoes, which had only been seen before in a small number of other supernovae.<\/p>\n

“The data set is remarkable and enabled us to produce very impressive coloured images and animations that exhibit the evolution of the light echoes over a five-year period,”<\/p><\/blockquote>\n

said lead scientist Professor Maximillian Stritzinger of Aarhus University.<\/p>\n

Colored images of the light echo associated with SN 2016adj. The dashed line highlights the position of the main light echo ring as it expands from the position of the supernova from 300 to 580 days post-explosion, along with a prevalent dust lane. The dust lane extends from east-northeast to west-southwest direction and clearly obscures both portions of the light echo and the background stars.

Even though the James Webb Space Telescope<\/a> has received a lot of attention, Hubble Space Telescope (HST) is still producing many excellent images of the cosmos.<\/p>\n

“HST has now been observing the sky for over three decades, so we can find things like this light echo that evolve slowly over many years,”<\/p><\/blockquote>\n

said co-author and astrophysicist Dr. Morgan Fraser, University College Dublin School of Physics.<\/p>\n

Supernova Blastwave<\/h2>\n

The strong 2016adj supernova explosion is sending a blast wave outward at a speed of more than 10,000 kilometres per second. The bright flash of light that the supernova released prior to this blastwave is what is causing the expanding rings that can be seen in the images.<\/p>\n
