There's a chorus of gravitational waves coming from the core of the Milky Way. Will we hear them?

There's a chorus of gravitational waves coming from the core of the Milky Way. Will we hear them?

There is a supermassive black hole at the center of our galaxy, and it's not alone. There is also likely a forest of binary black holes, neutron stars, and white dwarfs. All of these emit gravitational waves as they gradually spiral ever closer together. These gravitational waves are too faint for us to detect at the moment, but future observatories will be able to observe them. This poses an interesting astronomical challenge.

Like the musical instruments, the stars resonate with frequencies that astronomers can "hear" with the right instruments. This field of research is designated as atherossmology.

NASA Telescopes Capture Black Hole's Musical Prelude and Fugue

NASA recently unveiled an intriguing auditory experience derived from the cosmos, using data captured by its space telescopes to create soundscapes centered around black holes. These unique creations, known as sonifications, convert data into sound, offering a fresh perspective on these enigmatic celestial phenomena. This endeavor involves the Chandra X-ray Observatory, the James Webb Space […]

Scientists conducted an unusual experiment. They listened to "star music" that allowed them to estimate the age of the planet they were studying.

During four consecutive nights, the team used KPF to collect more than 2,000 ultraprecious measurements of the star's speed, capturing its vibrations in action.

Astronomers using the W. M. Keck Observatory in Maunakea, Hawaii Island, have heard the music of a nearby star, discovering surprises that shake our understanding of how stars work. The studio used the latest generation instrument from the Keck Observatory, the Keck Planet Finder (KPF), to detect oscillations that spread to [...]
