On International Cat Day on August 8, the European Space Agency showed a nebula that has the typical shape of a cat’s eye. The ESA has published a photo of a huge “cat’s eye”.

It is an interstellar agglomeration which resembles the pupil of the feline. This nebula is located in an area of ​​the universe that is 3,000 light years from Earth.

These forms are created by certain glowing gases. In fact, “cat’s eye” is not the scientific name of the interstellar cluster in question, which is instead called NGC 6543.

“Cat’s eye”, several hypotheses on this immense and spectacular nebula: the theories

The discovery of this nebula took place in 1786, but astronomers have continued to study it ever since. Now the European Space Agency has celebrated the cats by releasing a few photos, originally published in 2008, using NASA’s Hubble Telescope and in particular the ACS (Advanced Camera for Surveys).

According to astronomers, approximately every 1,500 years, the star at the center ejects its mass. The result is a powder with a spectacular effect.

At NASA, they wanted to understand why the central star had lost its mass. It is not excluded that cycles of magnetic activity similar to those of sunspots have occurred.

At the same time, pulsations of the stars were also speculated to be occurring as well as activities of other stars orbiting the dying one.

According to another hypothesis, the main star would have ejected matter in a less explosive way. This way, this dust could turn into concentric rings that formed the cat’s eye.
