The Hubble Space Telescope celebrates 32 years with stunning images of galaxies

NASA celebrates the 32nd birthday of the Hubble Space Telescope with a stunning look at an unusual array of five galaxies called the 40-Hixon Compact Group. Hubble Space Telescope at the age of 32, consists of three spiral galaxies, an elliptical galaxy and a lens-like galaxy. In a way, these various galaxies have evolved to form a very crowded collection of galaxies.

Following a slow gravitational dance, the whole group is as crowded as it can be. In an area of Space less than twice the diameter of the Milky Way star disk. Although such galaxy clusters can be found at the heart of massive galaxy clusters, these galaxies are specifically trapped in their tiny chunks of the universe in the direction of the constellation Hydra (narrow snake).

One possible explanation is that There is a lot of dark matter in connection with these galaxies. If they come together, dark matter can form a large cloud into which galaxies orbit, and as galaxies penetrate dark matter, they feel a force of resistance due to its gravitational effects. This effect slows them down, causing the galaxies to lose their energy and thus fall apart.

Thus, this image depicts galaxies at a particular moment in their life. In about 1 billion years, they will eventually collide to form a giant elliptical galaxy. Astronomers have studied this group of compact galaxies not only in visible light, but also in radio, infrared, and X-ray wavelengths. Be a major offense. X-ray observations show that the galaxies had a gravitational interaction due to the presence of very hot gas among them. Infrared observations also provide clues as to the speed at which a new star formed.

  • Scientists discovered the first generation of macromassive black holes Although more than 100 such compact galaxies have been listed in celestial mapping over the past few decades, the Hixon 40 compact group is one of the densest. Observations show that such compact clusters were probably more abundant in the early cosmos and provided fuel for the activity of black holes at the center of early galaxies, known as quasars, that emitted light from superheated falling material into space.

    Studying the details of galaxies in close groups like this helps astronomers understand what galaxies are made of and when and where their components come together. . "I remember seeing this on a sky map and saying, 'Wow, look at that,'" said Paul Hickson of the University of British Columbia in Vancouver, Canada. "While looking at the sky mapping photographs, all I had at the time was a large plastic ruler and a magnifying glass."

    The Halton Arp was released in 1966, rediscovered, and now the Hubble Space Telescope has released a spectacular image of them on the occasion of their 32nd birthday.

    Hubble on April 25, 1990 NASA Space exploration spacecraft deployed in Earth orbit. To date, the Telescope has made 1.5 million observations of about 50,000 celestial targets. This cosmic treasure trove of public access is stored in the Mikulski Space Telescope Archive at the Space Telescope Institute in Baltimore, Maryland.

    While Hubble has unique capabilities for observing visible and ultraviolet light, it now A vital scientific complement to infrared light observations, the James Webb Space Telescope, launched last Christmas, is set to begin scientific observations in the summer.
