Extremely large telescope ESO has recently taken an unprecedented picture of the two mixed and chaotic galaxies. These photos also contain many surprises about intruders both far and near.
Sometimes strange objects in the sky bring stories to us or are very scientifically valuable. This is an idea in the collection of Halton Arp's strange galaxies that appeared in the 1960s. One of those odd galaxies is the Arp 261. Thanks to the FORS 2 instrument on the VLT ESO telescope, it is Arp 261 was photographed with details never before. This photo also contains many surprising things.
Apr 261 is about 70 million light-years away in the constellation Libra. Its unusual chaotic structure is the work of interactions between two galaxies involved in slow motion, but a very close encounter that is destructive. Although single stars will not collide in an event like this, large clouds of gas and dust will inevitably crash into each other at high speeds, leading to the formation of new hot star clusters. can be clearly seen in the picture. The path of the stars present in the two galaxies will also be broken, creating a vortex swirling extending to the upper left and lower right of the image. Both interacting galaxies are probably dwarf galaxies like the Magellanic cloud orbiting our galaxy.
Arp color photographs 261 were created from photographs taken by the FORS2 instrument on the very large VLT ESO Telescope at the observatory Paraval, Chile. Located above sea level 2600m, on the mountain of the Atacama desert, Paranal observatory owns the darkest and most opulent skies on the planet. (Photo: Image courtesy of ESO)
The photos used to create this illustration are in fact not taken to study interacting galaxies, but to understand the properties of non-observable objects right to the light. most of Arp 261, near the center of the image. It is an unusual exploding star called SN 1995N, which is thought to be the result of the final collapse of a giant star in the final stages of life - the explosion of the super core. nova. SN 1995N is very special because it fades gradually, but it can still be seen clearly in the photo taken in the period after the explosion took more than 7 years! It is also one of the observed supernovae that emits X-rays. It is thought that these unusual traits are the result of a star exploding in a dense space so the matter flies. from supernova by launching that space, creating X-rays.
In addition to the interactive galaxies and supernovae, the image also contains several other objects at different distances than ours. In very close proximity are two asteroids belonging to the Solar System in the midst of Mars and Jupiter's orbits, which seem to just pass by 'photographed', revealing the green, green, and blue road. tree and red on the left and above the photo. The path appears when objects move through different color filters. The asteroid above is numbered 14670 and the asteroid on the left has the number 9735. Their width is probably less than 5km. Light reflected from these two small objects takes about 15 minutes to reach the Earth.
The next closest object is probably a bright star below the photo. It looks like it is very bright but it will actually fade a hundred times if you look only with the naked eye. It is a star that is almost like the Sun and is 500 light-years away - 20 million times farther away than the two asteroids . Galaxy 261, supernova lies farther than this star 140,000 times but astronomers still consider them our neighbors in the vast universe. Farther away, perhaps 50 to 100 times more distant than the Arp 261 galaxy, is a cluster of galaxies that can be observed to the right of the image. However, there is no doubt that there is a much more distant object, not discovered, on the background containing faint objects in this marvelous photo.
