670-million light years away! NASA Hubble Space Telescope snaps stunning galaxy merger
NASA's old faithful flying observatory, the Hubble Space Telescope never lets a chance go abegging when it comes to surprising everyone with its uncomonly rare and exciting discoveries. Yet again, the National Aeronautics and Space Administration (NASA) has shared a breathtaking glimpse of a rare merger of two galaxies taken by the Hubble Telescope. Thanks to the amazing capabilities of the more than 30-year old Hubble Telescope, which witnessed this unusual phenomenon the world has got the chance to grab a glimpse of a rare galaxy out there in space. NASA revealed that the stunning photo depicts the Galaxy merger Arp-Madore 417-391.
While sharing details about this Galaxy merger, NASA says, “The Arp-Madore catalog is a collection of particularly peculiar galaxies spread throughout the southern sky, and includes a collection of subtly interacting galaxies as well as more spectacular colliding galaxies.” This amalgamation of two galaxies sits around 670-million light years away in the constellation Eridanus in the southern celestial hemisphere.
How did these two galaxies merge? The space agency says that these galaxies were distorted amazingly by gravity and then twisted into a colossal ring while miraculously leaving their cores nestled side by side!
To capture this astonishing view, Hubble used its special instrument named Advanced Camera for Surveys (ACS), which is optimized to hunt for galaxies and galaxy clusters in the early universe. Hubble's ACS instrument has been a constant contributor to uncovering several scientific discoveries for the last 20 years. During its journey, Hubble's ACS has been involved in mapping the distribution of dark matter to studying the evolution of galaxy clusters.
