An amazing 1.3 gigapixel (1.3 billion pixel) image of the “Salis supernova remnant”, which is the remains left in space by a massive star that exploded as a supernova about 11,000 years ago, was captured by a ground-based telescope in Chile, South America. ) images have been released.
This image shows the National Science Foundation’s (NSF) Victor M at the Cerro Tololo Pan-American Observatory in Chile. The image was taken with the Dark Energy Camera (DECam) attached to the Blanco 4m telescope.

This spectacular image is available for download in an amazing 7 different resolutions. The download size for the highest quality image is 2.8GB. Also,Images that can be viewed online using the zoom functionare also provided.
The Blanco telescope reflects the collected light with a 4m diameter mirror, passes it through a correction lens, and directs it to 62 CCDs (imaging devices) arranged in a grid. CCD is similar to the camera sensor used in smartphone cameras. Image data was collected three times using three types of filters, each transmitting light at a different wavelength.
spider web filament
The image, the largest yet of the object, reveals an intricate web of filaments snaking throughout the expanding gas cloud. The striking red, yellow, and blue colors in this image were achieved using three DECam filters, each focusing on a specific color of light. This high-resolution color image was created by overlapping images taken individually with each filter.
closest to earth
Located about 800 light-years away in the constellation of Sails, this supernova remnant is one of the closest to Earth. This breathtakingly beautiful remnant of a star that violently exploded 11,000 years ago measures 100 light-years in diameter and has an apparent size equivalent to 20 full moons in the night sky. What we can now see is a cloud of gas glowing like plant tendrils, forming a web-like structure of thin gas filaments as the shock wave travels into space. is.
Supernova remnants
This is not the first time that high-resolution images have been created of a Scorpis supernova remnant. A 554-megapixel version was created in October 2022 using the European Southern Observatory’s (ESO) Very Large Telescope VLT, also located in Chile.

However, this image only shows the central region of the supernova remnant, which is only about nine full moons wide.
In December 2023, the James Webb Space Telescope (JWST) released the highest-resolution image ever of the supernova remnant Cassiopeia A. Cas A is located approximately 11,000 light-years away in the direction of the constellation Cassiopeia in the northern sky, which is famous for its W-shape. It has a diameter of 10 light years and has been the subject of much research.
