Boundless Universe.
Two incomparably massive giant nebulae are swiftly approaching one another.
These two giant nebulae are none other than the Galaxy Nebula and the Andromeda Nebula; the former has a diameter reaching 160,000 light-years, while the latter is 220,000 light-years across. Despite these figures seemingly being colossal, they are no more than the size of two pizzas in the perspective of the endless Universe.
Yet from a cosmic viewpoint, one could clearly discern the features of both nebulae.
The Galaxy Nebula is a barred spiral nebula, with a luminosity at its center that is exceedingly intense, especially the massive glowing bar composed of billions of old stars - it is even more magnificent and spectacular than the Sky Tower from the novels!
