Black holes were always invisible to humans for years, only theorized, but never imagined.
Until recently, the world''s first-ever image of a black hole was revealed. In an adolescent moment, not many were expecting, we can hear a black hole again.
A team of astrophysicists transformed the X-ray echoes of eight black hole binaries found in the Milky Way into sound waves, resulting in incredible results.
Researchers developed a new program called the "Reverberation Machine" that reveals the black hole in NICER, a telescope aboard the International Space Station, and converted them into sound waves. In this video, you may see the pictures below.
The scientists, who published their findings in The Astrophysical Journal, describe eight new black hole X-ray binaries as well as their repercussions.
These are produced when a black hole is orbiting and "feeding" on a large companion star, releasing an abundance of X-rays in the process. This allows astronomers to identify distant black holes that might otherwise be invisible. Some of these X-rays reflect off of the accretion disc, emitting the "echoes" selected by the team of scientists.
Entdecking the role of black holes in galaxy evolution
Astrophysicists collected their data to learn more about the evolution of black holes as they feed on nearby stars." In a press release, MIT astrophysicist Erin Kara, who has co-authored the study, explained the role of black holes in galaxy evolution.
"Interestingly, these black hole binaries appear to be''mini''''supermassive black holes, according to Kara, and thus, by understanding the outbursts in these small, nearby systems, we can conceive how similar outbursts in supermassive black holes affect the galaxies in which they reside."
Kara is working with MIT education and music organizations to convert the emission of a black hole X-ray echo into audible sound waves. The lower frequency light was converted to lower pitches, and the high-frequency light was converted to higher pitches. These results, in the video above, give a satisfyingly eerie result that would be perfect at home in any sci-fi thriller.
