Astronomers Unearth an Unbelievable 'Sideways' Black Hole in NGC 5084

In a groundbreaking revelation announced on December 18, 2024, NASA researchers have discovered a supermassive black hole in the galaxy NGC 5084 that is spinning in a bizarre, tilted orientation, distinctively out of sync with the galaxy itself. This extraordinary finding challenges the conventional understanding of black holes and their alignment within galaxies.

First spotted centuries ago by the renowned astronomer William Herschel, NGC 5084 has long intrigued scientists. However, a revolutionary new technique called SAUNAS (Selective Amplification of Ultra Noisy Astronomical Signal) developed at NASA’s Ames Research Center has brought to light the peculiar properties of this black hole. This innovative method allows astronomers to isolate and scrutinize low-brightness X-ray emissions that earlier observations failed to detect amidst the background noise.

When NASA's team meticulously analyzed archival data from the Chandra X-ray Observatory—often referred to as the X-ray counterpart of the Hubble Space Telescope—they stumbled upon the enigmatic phenomenon. The new analysis revealed four substantial X-ray plumes emanating from the galaxy's core, with two aligned along the galaxy's galactic plane and the others extending vertically, an occurrence that is unprecedented in astronomical observations.

Typically, galaxies might showcase one or two such plumes, but four is exceptionally rare—especially when they appear symmetrically concerning the galactic plane. To validate their findings, the scientists expanded their investigation using images from the Hubble Space Telescope and the Atacama Large Millimeter Array (ALMA), which revealed an inner disk of dust spinning at a 90-degree angle, further supporting their hypothesis of an unusual galactic core.

Lead author and Ames research scientist Alejandro Serrano Borlaff likened their findings to piecing together evidence at a crime scene: 'It was like seeing a crime scene with multiple types of light. Putting all the pictures together revealed that NGC 5084 has changed a lot in its recent past.' Co-author Pamela Marcum highlighted the significance of their discovery, asserting that the unique cross-shaped structure of the X-ray plumes combined with the tilted dusty disk are key indicators of the galaxy's tumultuous history.

The implications of this discovery are profound. The unusual orientation of NGC 5084’s black hole suggests it may have experienced a violent disturbance, potentially from a collision with another galaxy. Such cosmic events could provide insight into the dynamic processes that shape galaxies over time, revealing that even seemingly stable systems have extraordinary backstories.

The deployment of SAUNAS illustrates the potential for reexamining older data with fresh techniques, igniting excitement among astronomers that further oddities may lie hidden in well-studied galaxies. This astonishing twist in our knowledge of NGC 5084, a galaxy known to us since 1785, opens the door for future astronomical discoveries that could redefine our understanding of the universe.
