New Discovery by the Hubble Telescope.

NASA’s Hubble Space Telescope has found a strange, elongated, pearl-like pillar almost hidden within two merging elliptical galaxies. The twisting pillar-like object is 100,000 light-years long and blue in color. In reality, it is a massive young star cluster.

Researchers say, “You have set your sights on a beautiful structure. And we will be able to learn much more about this.” They added that they were amazed to have discovered this extraordinary object. Grant Tremblay, the lead researcher from the European Southern Observatory in Garching, Germany, said this in a statement.

He stated, “We’ve seen such a massive star cluster arrangement in the central region of a giant merging elliptical galaxy, but we can’t say for sure if we have ever seen something quite like this before. This is because the object is located at the edge of the galaxy’s arm, in a region of incredibly strong gravitational force.” The star cluster existing between these two galaxies is known as J1531+3414, and the pair of galaxies are 330,000 light-years across.

The researchers mentioned, “For comparison, our own Milky Way is about 100,000 light-years across.” This formation of the young, large blue cluster was accompanied by a powerful burst of energy during the process of star formation—a result of nuclear explosions as new stars formed. Whatever the origin of this star-forming gas may be, Tremblay said, “It’s very exciting. You or I can’t find a mundane explanation for this. More research is needed.”

In Hubble’s new photo, the intense light produced by the bright blue cluster’s powerful gravity is seen spreading as far as distant galaxies.
