Latest stunning image of 1.3 billion pixel 'Salis supernova remnant' taken from a mountaintop in Chile, South America | Forbes Japan official website (Forbes Japan)

A stunning 1.3 gigapixel (1.3 billion pixel) image of the Sallis supernova remnant, the remains of a massive star that exploded as a supernova about 11,000 years ago, has been captured by a ground-based telescope in Chile, South America.) Images have been released.

This photo shows Victor M. of the National Science Foundation (NSF) at the Cerro Tololo Inter-American Observatory in Chile. The image was taken with the Dark Energy Camera (DECam) attached to the Blanco 4M telescope.

The Blanco telescope reflects the collected light with a 4-meter diameter mirror, passes it through a correcting lens, and directs it to 62 CCDs (imaging devices) arranged in a grid. A 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.

The image, the largest yet of the object, reveals a complex network of filaments coiled throughout the expanding gas cloud. The stunning 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

The supernova remnant is located about 800 light-years away in the constellation Sails, and is one of the closest supernova remnants to Earth. This stunningly beautiful remnant of a star that violently exploded 11,000 years ago is 100 light-years in diameter and has an apparent size equivalent to 20 full moons in the night sky. What we can see now is a cloud of gas glowing like plant tendrils, forming a net-like structure of thin filaments of gas as the shock wave travels out into space.

Supernova remnants

This is not the first time high-resolution images of a Scorpio supernova remnant have been created. A 554-megapixel version was created in October 2022 using the European Southern Observatory's (ESO) Very Large Telescope (VLT), also in Chile. this picture1.1 GB fileIt can be downloaded asView online using zoom functionYou can also do this. However, this image only shows the central region of the supernova remnant, which is only about nine full moons across.

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 years Light, and has been the subject of much research.
