NuSTAR Discovers Chorus of Black Holes

TEHRAN (Tasnim) – Just like the movies where every scene has background music, the universe too has an infinite loop of its own.

NuSTAR Discovers Chorus of Black Holes

After surveying the largest cosmic gig, NASA has finally identified the black holes that create these x-ray sounds - all this with the help of NuSTAR. 

NuSTAR stands for Nuclear Spectroscopic Telescope Array. It's a device used by NASA to locate black holes which emit high-energy x-rays. The chorus of black holes that emitted the x-ray sounds were spotted and studied by astronomers at the Californian Institute of Technology. These cosmic x-rays produce sounds at the highest pitch.

"We knew this cosmic choir had a strong high-pitched component, but we still don't know if it comes from a lot of smaller, quiet singers, or a few with loud voices," stated Daniel Stern, project scientist of NuSTAR located in NASA's Jet Propulsion Laboratory in Pasadena, Calif. "Now, thanks to NuSTAR, we're gaining a better understanding of the black holes and starting to address these questions."

Chandra X-ray observatory by NASA deduced that the black holes made the sounds. Yet, what exactly causes these cosmic x-ray sounds? The "background music" occurs when black holes consume their surroundings.

The discovery, thanks to NuSTAR, finally explains the mysterious songs caused by the black holes. According to NASA, the high-pitched "voices" caused by black holes are the most difficult to define. Long before NuSTAR, astronomers had difficulties in establishing patterns involving black holes.

NuSTAR was created thanks to a partnership between the Danish Technical University and the Italian Space Agency (ASI). Since the creation of NuSTAR, 32 black holes in the universe have been discovered. It has resolved approximately 35 percent of x-ray songs caused by black holes.
