Look at the nebula with a huge space cave: no one knows how it came to be

NASA's Goddard Space Flight Center has released a new image from the Hubble Space Telescope. He

 photographed an unusual object —The N44 nebula is filled with glowing hydrogen gas, dark lanes of dust, massive stars, and multiple populations of stars of varying ages. One of the features is a dark star gap or hole called a “superbubble.” It is clearly visible in the picture.

The hole is about 250 light-years wide.How and why it appeared is still a mystery. According to one theory, stellar winds emitted by massive stars inside the bubble could ward off gas. Also the possibly expanding shells of old supernovae have formed a space cave.

Astronomers have discovered one supernova remnantnext to the hole and determined the difference in age between the stars inside and at the edge of the gap - it was 5 million years. As noted by NASA, this indicates multiple star formation chain reactions. The dark blue in the image is one of the hottest regions of the nebula and the region with the most intense star formation.

N44 is  in the Large Magellanic Cloud, its size is about 1,000 light years. The nebula itself is located about 170,000 light years from Earth.
