Looking at this celestial image, what do you imagine?

This is the European Southern Observatory (IT’S)But2022year10moon31Introduced in the date (Halloween day), in the southern sky“Vela Supernova Remnant”This is an image of ESO is named following Halloween.IT’Scaptured the ghost of a giant star (ESO captures the ghost of a giant star)”, and the beginning of the commentary is also expressed as “A spooky spider web? A magic dragon? Or a faint footprint of a ghost?”

Supernova remnants are more than eight times heavier than the Sunmassive starcaused bysupernova explosionA celestial body observed followingThe pale cloud-like pink and orange structure of the Vela supernova remnant ended its stellar life in a supernova explosion.massive staris left by A neutron star or black hole may be left following a supernova, but it seems that a pulsar (a type of neutron star) that rotates at a speed of more than 10 times per second is left behind in the Vela supernova remnant.

The currently observed Vela supernova remnant isAbout 11,000 years following the supernova explosionis believed to have passed.Caused by a supernova explosionshock wavecompresses the gas around the star and creates a complex structure like a twisted thread.The energy released during this timegas heatedBy being done like thisshine brightIt is.

This image captures an area as large as nine full moons as seen from Earth, but the Vela supernova remnant extends far beyond the image. Vela supernova remnant just a few feet from Earth, according to ESO800 light yearsbut far away,The closest supernova remnant to EarthIt is said that it can be counted as one of

This image captures the Vela supernova remnant beautifully.IT’Sinstalled at the Paranal Observatory in“VLT Survey Telescope”（VLT Survey Telescope：VST) wide-field camera「OmegaCAM」was taken using The number of pixels of the original image reaches 554 million pixels.

2000000006800The megapixel OmegaCAM can use filters that transmit light of various colors (wavelengths) when shooting. This time, images acquired using five filters that pass specific ultraviolet rays, visible rays, and infrared rays were colored in four colors, magenta, blue, green, and red, and synthesized. The filamentary gas of the supernova remnant and the brightness of the bright blue star in front of it are captured in great detail.

ESO has also released a video that will make you feel like you’re flying through the Vela supernova remnant. If you were not conscious of Halloween, what would you associate with it?
