Giant pupils in the universe

The sight of a star spraying dust and gas in the dying process makes viewers think of the great cornea.

The spherical material belt and the star form something like a cornea.

The star, known as U Camelopardis and belonging to the constellation Camelopardalis (Giraffe) , is in the final stages of life, the European Space Agency (ESA) said. Helium gas in its core is about to run out and it becomes an unstable body. Every few thousand years, U Camelopardis "sprayed" dust and gas once. Dust and gas from the star form a belt around the star core. Hubble Space Telescope has captured its latest material injection.

U Camelopardis is a representative representative of carbon stars, a rare star in the universe, National Geographic said. The carbon star's atmosphere contains more carbon than oxygen. The attraction of carbon stars is relatively weak, so strong winds on their surfaces can blow matter into the universe. Many carbon stars lose up to 50% of their mass due to the effects of strong winds.
