New NASA Black Hole Sonifications with a Remix
Since 2003, the black hole at the center of the Perseus galaxy cluster has been associated with sound. This is because astronomers discovered that pressure waves sent out by the black hole caused ripples in the cluster’s hot gas that could be translated into a note – one that humans cannot hear some 57 octaves below middle C. A new sonification – the translation of astronomical data into sound – brings more notes to this black hole sound machine.

Hubble Views a Galactic Oddity
The ultra-diffuse galaxy GAMA 526784 appears as a tenuous patch of light in an image from NASA’s Hubble Space Telescope. This wispy object resides in the constellation Hydra, roughly four billion light-years from Earth. Ultra-diffuse galaxies such as GAMA 526784 have a number of peculiarities. For example, they can have either very low or high amounts of dark matter, the invisible substance thought to make up the majority of matter in the universe.

NASA Visualization Rounds Up the Best-Known Black Hole Systems
Nearby black holes and their stellar companions form an astrophysical rogues’ gallery in a new NASA visualization. Stars born with more than about 20 times the Sun’s mass end their lives as black holes. As the name implies, black holes don’t glow on their own because nothing can escape them, not even light.
