Nebula ESO 378-1 glows in the universe

ABC Science today reported that a large- sized telescope in the Southern European Observatory (Chile) captured the image of the ESO 378-1 nebula , also known as Southern Owl Nebula , a wide ionizing gas sphere. with 4 light years in the constellation Hydra .

The color of the nebula results from the ultraviolet radiation emitted by the dying star. This star ionizes the surrounding shell, causing hydrogen, helium, nitrogen, oxygen and many other elements to burn brightly, like the way electric light illuminates neon bulbs.

When the stars exhausted the materials to burn, preparing to switch to the red dwarf phase, the outer shell of gas will expand and cool. Nuclear fusion ends at the core of the stars and they will experience a powerful explosion no less than supernova explosions .

However, small stars like the Sun end their existence in a lighter way. Their outer shell will continue to spread until it is no longer affected by gravity and blown by the wind.

The nebula is a phenomenon that lasts only a short time, lasting tens of thousands of years before the constituent gases dissipate and dissolve into the physical environment between stars, laying the foundation for the formation of stars. and new planets in the future.
