On April 23, 2019 (March 19, 2019, the lunar calendar), Hubble discovered the mysterious galaxy jellyfish. History Today, April 23, 2019. The universe is amazing with its incomparably wide space and various magical celestial bodies. Although modern science is very developed, mankind has achieved achievements in exploring the mysteries of the universe., it can still be said to be a drop in the bucket. However, fortunately, with the continuous advancement of science and technology, humans have been able to use various observation equipment to see distant space that cannot be seen with the naked eye, thereby discovering more magical things. Space telescopes are such a kind of equipment. It extends the vision of scientists and expands the vision of mankind. It can be said to be the clairvoyance and ears of modern astronomy. About nine years ago, NASA's Hubble Space Telescope observed a distant mysterious galaxy with two long tails that reached an astonishing 260,000 light-years long. Recently, the Hubble Telescope has made a new discovery: this mysterious galaxy is actually almost a giant cosmic "jellyfish" in shape, wandering in the ethereal and nothingness of space, confusing scientists. Jellyfish may be the oldest and most charming animal on the planet. It appeared on earth 650 million years ago and is found in waters around the world. Jellyfish account for 95% water, 3% salt, and only 2% protein. Jellyfish float in the sea and look beautiful and intoxicating. The largest jellyfish can be tens of meters long. There is even a lighthouse jellyfish that can live forever by rejuvenating and skipping the process of death. Isn't it amazing? There is such a charming guy in the vast universe, but it is not a living creature, but a dazzling giant galaxy. This mysterious galaxy is called ESO137 -001. It is a huge rod-spiral galaxy similar to our Milky Way, but unlike our Milky Way, it has a huge tail that is 260000 light-years long, which makes it look like It looks like a beautiful jellyfish floating in the vast space, but also like a galaxy wandering in the universe! ESO137 -001 is about 220 million light-years away from our Earth and was first discovered by the Hubble Telescope and the Chandra X-ray Observatory in 2014. NASA recently released its composite photo of the bright galactic disk, blue ribbons of young stars appear to be the long tentacles of galaxy jellyfish, propelling the galaxy through space. The specks of starlight in the background and foreground make the entire "jellyfish" seem mysterious and beautiful, quiet out of the vastness of the universe and distant in time and space. These blue ribbons are actually stripped off high-temperature gas. ESO137 -001 is a member of the Abell 3627 galaxy cluster. It is rushing towards the central region of the galaxy cluster. For some unknown reason, these gases are stripped off like comets, forming a beautiful molecular cloud that is 260,000 light-years long and looks like jellyfish tentacles. The most amazing thing is that these gases are actually gathering together to form young stars, thus showing a vibrant blue color. This makes it very difficult for scientists to understand, because under normal circumstances, molecular clouds that have formed stars will be tightly bonded to the galaxy due to gravity, but this jellyfish galaxy has formed many stars in its illusory tail. Stacy Alberts, a researcher at the University of Arizona, believes that either our previous theory was wrong, or the gases were heated and stripped off, then cooled again to form stars. But no matter what, this unique jellyfish tentacles have had a significant impact on the evolution of the entire galaxy, resulting in a decline in the rate of star formation in the galaxy and affecting the shape changes of the galaxy. The vastness of the universe leads to infinite mysteries. How much more are we unaware of? Scientists are pinning their hopes on James Webb, the most powerful telescope in history to be launched, to reveal the secret of how the tail of the jellyfish galaxy was peeled away from the galaxy. Or on the huge astronomical scale of time and space, these galaxies are originally living life? Of course, even so, this kind of life is meaningless to us. We live in worlds separated by huge differences in time and space, without interfering with each other or having any intersection. Life is unpredictable, not only at this moment, in the life forms you and I know well, but also in the entire universe and time, any potential life forms that may exist.
