Colourful ghostly remnants drift in area the place an enormous star exploded 11,000 years in the past.

The Vela supernova remnant, named after the constellation Vela, is all that is still after a star has reached the top of its life.

Pink and orange gasoline clouds mark the spot 800 light-years from Earth, making it one of many nearest identified options. (A light-weight yr is about 6 trillion miles.)

When a star went supernova, shock waves traveled by way of the encompassing layers of gasoline that the star was giving off.

The energetic waves compressed the gasoline and created thread-like filaments that resemble a wonderful internet.

In a brand new picture of the Velo supernova remnant, taken by the VLT Survey Telescope on the European Southern Observatory in Chile, filaments of glowing gasoline glow attributable to warmth from shock waves.

The hauntingly stunning scene the place the star died was fittingly posted on Halloween.

The remnant is a dense neutron star, or pulsar, that spins quickly and emits beams of sunshine like a celestial beacon, however it’s not removed from the area proven within the picture.

9 full moons match into an in depth perspective, and the picture reveals solely a part of the enormous cloud.

The European Southern Observatory additionally shared detailed views of fascinating parts of the mosaic. 12 highlights enlarge varied points of the area’s brilliant stars and gasoline clouds.

Dazzling colors and starlight merge in a new image of the Velo supernova remnant.

The picture, containing 554 million pixels, was taken by the wide-field OmegaCAM on the telescope. The 268 million pixel digicam is able to capturing photos utilizing a number of totally different filters that enable for various wavelengths of sunshine and colours – therefore the magenta, blue, inexperienced and purple colours within the picture.

The VLT Survey Telescope is likely one of the largest telescopes to survey the evening sky utilizing seen gentle, serving to astronomers unlock the secrets and techniques of star formation and dying.
