Now we know that phenomena such as gravitational waves, and even primordial sounds from the dawn of the universe, can be “heard” by telescopes. It used to be thought that space was silent. The human ear is only capable of hearing 10 octaves lower than middle C. “It showcases a unique approach to processing data about sound through sound, almost 20 years later, to help add new value for the scientific findings.”Īstronomers detected sound waves coming from Perseus in 2003, more proof that space has its own peculiar music, when they were found to be the equivalent of a note 57 octaves below middle C. “This project is a whole other way to translate ‘invisible’ X-ray data,” she told SYFY WIRE. Visualization scientist Kimberly Arcand of the Chandra X-ray Center (CXC) was involved in morphing an inaudible noise from space into something that could have come off an ambient soundtrack for a haunted house. Sound waves are pressure waves, so the idea really isn’t too far out. While there have been sonifications for other black holes, and a new one for M87, the first whose glowing accretion disc was ever imaged, this stands out because it is based on the actual sound waves that showed up in the data. The black hole lurking in Perseus was previously known to produce some kind of sound. Now NASA scientists have translated that data into a sound we actually can hear, and it’s spooky. NASA’s Chandra X-ray Observatory was able to “hear” a black hole in the Perseus galaxy cluster through the detection of pressure waves that cause ripples in the cluster’s hot gas, but it was at a pitch way too low for human ears to make out (no word on what Cylons might have been able to pick up). Never mind anything that close to a black hole would be overcome by the beast’s gravity and fall towards its gaping maw - if it wasn’t already crushed. They were surprised to spot the monumental discovery in what may be considered a more obvious location, suggesting the possibility of many more similar objects.If the Battlestar Galactica universe was real and you were a Cylon living in The Colony, which is right on the edge of a black hole, what would you hear? Other interpretations of the data are possible, but scientists say the observations are in strong agreement with their earlier theories. "Our discovery provides an example of precursors to the supermassive black holes we observe at later epochs." "GNz7q provides a direct connection between these two rare populations and provides a new avenue toward understanding the rapid growth of supermassive black holes in the early days of the universe," continued Fujimoto. It will eventually become an extremely bright quasar once the dust is gone. "The object's properties across the electromagnetic spectrum are in excellent agreement with predictions from theoretical simulations." This is an artist's impression of a supermassive black hole that is inside the dust-shrouded core of a vigorously star-forming "starburst" galaxy. "Our analysis suggests that GNz7q is the first example of a rapidly growing black hole in the dusty core of a starburst galaxy at an epoch close to the earliest supermassive black hole known in the universe," said lead author Seiji Fujimoto. The findings are published in the journal Nature. This type of black hole that transforms into an extremely luminous quasar was predicted by theories and computer simulations but never observed - until now. They say the best explanation is a fast-growing black hole covered in dust, which will eventually emerge as a quasar, a brilliant source of light at the heart of a baby galaxy. Scientists found a compact source of ultraviolet and infrared light, which could not be attributed to star formation alone rather, it matches the radiation expected by materials falling into a black hole.

The object, which is referred to as GNz7q, is the red dot in the center of the image of the Hubble Great Observatories Origins Deep Survey-North. An international team of astronomers has discovered a unique object in the distant universe that is a crucial link between young star-forming galaxies and the earliest supermassive black holes. ![]() It's the first of its kind to be discovered. Using archival data from Hubble's Advanced Camera for Surveys, a team of international researchers determined the "monster" object existed just 750 million years after the Big Bang, during the "cosmic dawn" - the early period after the birth of our universe.
