The delicate structure of the Philae supernova remnant was imaged with the Dark Energy Camera sorae satellite portal website

This is located near the center of the supernova remnant, the Saila supernova remnant, about 800 light-years away in the direction of the Saila supernova remnant. The intricately interwoven thread-like (chain-like) fine structure is captured and is bright throughout the field of view.

According to the National Science Foundation's (NSF) National Optical and Infrared Astronomy Laboratory (NOIRLab), which released the image, the Phila supernova remnant is about 100 light-years across. The size as seen from Earth is approximately 20 times the apparent diameter of the full moon, but what is shown here is only a part of it, and the width of the image is approximately equivalent to 5 full moons (161.11 x 161.53 arcsec).

A supernova remnant is a celestial object observed after a supernova explosion. Electromagnetic waves such as visible light and X-rays are thought to be emitted when shock waves heat the gas surrounding the exploding star. The star that left behind the Philae supernova remnant has ended its life as a star, but the shock wave from that explosion is visible as a pale arc extending from the top left to the bottom of the image.

The Philae supernova remnant is believed to be the remnant of a Type II supernova that occurred about 11,000 years before the current state was observed. A type II supernova is a type of supernova explosion caused by a massive star more than 8 times heavier than the Sun. An iron core is produced by a nuclear fusion reaction inside a massive star that has evolved into a red supergiant. It is believed that when this happens, the core, which… No longer able to support its own weight due to the energy of nuclear fusion, it collapses, causing an explosion that blows away the star's outer layer. Also, after a supernova explosion, extremely dense and compact celestial objects such as neutron stars and black holes may be left behind. A pulsar, a type of neutron star that regularly emits electromagnetic waves, was found near the bottom of the image in the Vela supernova remnant and has been named the Vela Pulsar.

This image was created based on observational data from the Dark Energy Camera (DECam), an observing device mounted on the Blanco 4-meter telescope at the Cerro Tololo Inter-American Observatory in Chile. As its name suggests, the DECam is an observing device developed for the main purpose of searching for dark energy. It has a resolution of about 520 megapixels and an area equivalent to about 14 full moons (3 square degrees), and you can shoot at once. Observations for the original purpose of dark energy research were conducted from 2013 to 2019.

The first image was published by NOIRLab on March 12, 2024. According to NOIRLab, the image of the Vela supernova remnant released this time is approximately 1.28 gigapixels (35,786 x 35,881 pixels), the largest image created based on DECam observational data. The images posted in this article have been reduced in size, but NOIRLab has also released a zoom-compatible version at the following URL, so if you're interested, please visit and enjoy!
