What is there in the sky? In 1985, this object was discovered by Arthur Gomez and became known as Gomez' hamburger because of its particular shape. Research allowed to identify this object as protoplanetary nebula - a gas cloud emitted by a star similar to the Sun after all the hydrogen in its nucleus has been burnt and turned into helium. Luminous areas resembling halves of hamburger are the light of a central star. The star itself is hidden behind a thick dust disk that passes in the middle (like chopped meat in a hamburger). The Center's answer: The central part is a solid body. The light lines are remnants of an object 10 times as powerful as the Sun, divided as the result of an explosion.
