The Space Telescope Hubblea prodigy of space technology, has captured a truly impressive scene in the cosmos: the famous “dance galactic“from a trio of galaxies in interaction known as Arp-Madore 2339-661. This fascinating cosmic event, cataloged within the collection of galaxies peculiar to Arp-Madore, has perplexed astronomers and generated excitement in the scientific community.
At first glance, you might think that only two galaxies are involved, but closer examination reveals a third actor in this extraordinary space ballet. Both galaxies Clearly identifiable in this cosmic scene are NGC 7733 and NGC 7734. NGC 7733, the smaller of the two, is located at the bottom right of the imagewhile NGC 7734, the largest and most majestic, is located in the upper left corner.
But the real surprise and the center of attention falls on the third galaxy, often referred to as NGC 7733N. NGC 7733N is located in the upper arm of NGC 7733 and appears as a knot-like structure, which emits a different color than the arm and is partially hidden by dense clouds of cosmic dust.
What does the galactic dance captured by Hubble mean?
At first glance, we could assume that NGC 7733N is part of NGC 7733, merging in some way with it. galaxy. However, deeper astronomical analysis, including evaluation of the speeds and directions involved, has revealed a fascinating fact. NGC 7733N exhibits significant additional redshift, suggesting it is highly likely to be its own entity galactic and not a mere appendix to NGC 7733.
This discovery poses a unique challenge for observational astronomers: determining the true nature of an astronomical object. Sometimes these cosmic observations can cause confusion, since the terrestrial perspective can hide or superimpose celestial objects, which requires careful investigation.
This cosmic spectacle takes place at a significant distance from our planet, approximately 500 million light years from Earth. This impressive set of galaxies It is located in the constellation of Tucana, and, as the image, they interact with each other in a gravitational way. In fact, some experts refer to this celestial group as a “merging group,” implying that these three galaxies They will eventually come together and evolve into a unique entity in the vast landscape of the universe.
The Space Telescope Hubblea joint creation of the POT and ESA, has played a fundamental role in the exploration and discovery of cosmic phenomena. This sophisticated observation tool has allowed astronomers to capture images spectacular views and collect valuable data that has improved our understanding of the universe. The image of the “galactic dance” of Arp-Madore 2339-661 shows the ability of the Hubble in the field of astronomy and cosmology.
