Astronomers utilizing the effective Dark Energy Camera (DECam) on the Víctor M. Blanco 4-m telescope at Cerro Tololo Inter-American Observatory, a Program of NSF's NOIRLab, have actually built a huge 1.3-gigapixel picture of the Vela supernova residue, a residue of an enormous star that blew up almost 11,000 years earlier in the constellation of Vela.

The Vela supernova residue, Vela SNR for brief, is among the very best studied supernova residues in the sky and among the nearby to Earth.
Its progenitor star took off in between 11,000 and 12,300 years back in the southern constellation of Vela.
The association of this supernova residue with the Vela pulsar, made by Australian astronomers in 1968, was the direct observational proof that supernovae type neutron stars.
“When the star blew up 11,000 years back, its external layers were strongly removed away and flung into the surrounding area, driving the shockwave that is still noticeable today,” the astronomers stated in a declaration.
“As the shockwave broadens into the surrounding area, the hot, stimulated gas flies far from the point of detonation, compressing and engaging with the interstellar medium to produce the stringy blue and yellow filaments seen in the image.”
“Vela SNR is an enormous structure, covering nearly 100 light-years and encompassing twenty times the size of the moon in the night sky.”
“Despite the dramatics of the star's last minutes, it wasn't completely cleaned from presence.”
“After shedding its external layers, the core of the star collapsed into a neutron star– an ultra-dense ball including protons and electrons that have actually been smashed together to form neutrons.”
“The neutron star, called the Vela pulsar, is now an ultra-condensed item with the mass of a star like the Sun consisted of in a sphere simply a couple of kilometers throughout.”
“Located in the lower left area of this image, the Vela pulsar is a reasonably dim star that is equivalent from its countless celestial next-door neighbors.”
The brand-new picture of Vela SNR is the biggest DECam image ever launched openly, including an astonishing 1.3 gigapixels.
“The striking reds, yellows, and blues in this image were attained through using 3 DECam filters that each gathers a particular color of light,” the scientists stated.
“Separate images were taken in each filter and after that stacked on top of each other to produce this high-resolution color image that showcases the complex web-like filaments snaking throughout the broadening cloud of gas.”
