These delicate wisps of gas make up an object known as SNR B0519-69.0, or SNR 0519 for short. The thin, blood-red shells are actually the remnants from when an unstable progenitor star exploded violently as a supernova around 600 years ago. There are several types of supernova, but for SNR 0519 the star that exploded is known to have been a white dwarf star — a Sun-like star in the final stages of its life. SNR 0519 is located over 150 000 light-years from Earth in the southern constellation of Dorado (The Dolphinfish), a constellation that also contains most of our neighbouring galaxy the Large Magellanic Cloud (LMC). Because of this, this region of the sky is full of intriguing and beautiful deep sky objects. The LMC orbits the Milky Way galaxy as a satellite and is the fourth largest in our group of galaxies, the Local Group. SNR 0519 is not alone in the LMC; the NASA/ESA Hubble Space Telescope also came across a similar bauble a few years ago in SNR B0509-67.5, a supernova of the same type as SNR 0519 with a strikingly similar appearance. A version of this image was submitted to the Hubble’s Hidden Treasures Image Processing Competition by Claude Cornen, and won sixth prize.

Estos trazos finos de gas conforman un objeto conocido como SNR B0519-69.0, o SNR 0519. Las delgadas capas rojas son de hecho remanentes del momento en el que una estrella inestable estalló violentamente y se convirtió en una supernova hace 600 años.

Hay varias clases de supernovas, pero en el caso de SNR 0519 se sabe que la estrella que estalló era una enana blanca, una estrella similar al Sol pero en las últimas etapas de su vida.

SNR 0519 se localiza a 150 mil años luz de distancia de la Tierra en la constelación de Dorado en el Hemisferio Sur, una constelación que contiene a la Gran Nube de Magallanes. Por esta razón, esta región del cielo está llena de objetos hermosos e intrigantes del cielo profundo. La Gran Nube de Magallanes orbita a la Vía Láctea como un satélite y es la cuarta más grande en nuestro grupo de galaxias denominado el “Grupo Local”.
