In May 2020, a study was published in the journal Nature-Astronomy, which was discovered based on spectral data from the Keck Observatory mobile phone in Hawaii and images taken by the Hubble Space Telescope . The reason why this galaxy is strange is that due to gravity, the core star clusters will form an light ball very densely, while the core part of this galaxy is a huge hole, with a diameter of more than 17,000 light years.
The technological development of human beings over the years is like flying. In the 1990s, humans launched the first space telescope - Hubble . Over the past 30 years, Hubble Space Telescope has dutifully sent back millions of cosmic photos to the earth, constantly refreshing our understanding of the spectacular universe.
According to the observations of Hubble Telescope , R5519 is about 10.8 billion light years away from the earth, which is an amazing interstellar space. It is worth noting that the R5519 has a diameter of about 42,000 light years, which is much smaller than the Milky Way . Most notably, based on the collected spectra effect, scientists discovered that the central area of R5519 is a huge black hole with a diameter of about 17,000 light years. Scientists in the
group said in their paper that they discovered the ruins of the "Star Wars" 11 billion light years away from the Earth through observations. However, the so-called "Star Wars" did not have a high-tech battle between alien civilizations, but a phenomenon in the evolution of the universe - galaxy collision. It is worth mentioning that this is also the first "collision ring galaxy" discovered by humans. People named this galaxy r5519.
In other words, this huge black hole area has almost no stars, which is an extremely unusual cosmic phenomenon. It is worth noting that unlike most stars in the universe where most of the stars are concentrated in the center, the situation of R5519 is different.
Scientists analyzed that the predecessor of this galaxy should be a disc-shaped galaxy, which was hit by another galaxy head-on and penetrated through the body, thus knocking a large hole into the core of this disc-shaped galaxy. Further research has found that in the ring of this ring galaxy, the star formation speed is very fast, 50 times the speed of the Milky Way star formation.
It is worth noting that the star density of R5519 decreases from the outside to the inside. Some scientists suspect that the existence of R5519 seems to be disturbed by some external force. So what is this external force? According to this logic, scientists discovered the "suspicious" galaxy G5593 not far from R5519. The galaxy broke into R5519 about 40 million years ago and passed through the interior of R5519 at an extremely fast speed, carrying most of the stars in the center of R5519. And R5519 seems to be a relic after Star Wars.
This proves the existence of this impact from another aspect. It is a huge impact that crashes the gas and dust of the galaxy into the ring-shaped part of the edge, breaking the gravitational balance there, which leads to the acceleration of the nebula gathering speed and the greatly accelerated star formation speed. There has always been a scientific assumption regarding the division of stellar civilizations. Some people divide space civilization into three levels. The first civilization is the most basic and has the lowest level of science and technology. It can only utilize planetary resources, and its activities are limited to planets. The second type of civilization has a high level of technology and can use the resources of stars, and its range of activities is large, so it can move freely in star system ; the third type of civilization has a high level of technology and can use the resources of stars and galaxies for your own use. According to the standards of interstellar civilization classification, the energy that can decompose the "R5519" galaxy is most likely to come from the Type 3 civilization, which shows that the technical level of the Type 3 civilization is quite amazing.
