Identifying the gravitational waves from black holes binaries could also make it clearer to detect primordial gravitational ...

Researchers analyzing pulsar data have found tantalizing hints of ultra-slow gravitational waves. A team from Hirosaki University suggests these signals might carry “beats” — patterns formed by ...

A new paper presents a method for distinguishing between different sources of nanohertz gravitational waves. Pulsars may be revealing faint ripples in the fabric of the universe, ultra–low-frequency ...

Explore 10 breathtaking images of pink nebulae and supernovae captured by NASA, showcasing the beauty, mystery, and explosive ...

Pulsars suggest that ultra–low-frequency gravitational waves are rippling through the cosmos. The signal seen by international pulsar timing array collaborations in 2023 could come from a stochastic ...

Greetings stargazers. The night sky is changing. I am not talking about stars disappearing because of light pollution, even thought that is certainly an issue, but I am thinking of all the ways the ...

Astronomers studying the supermassive black hole M87*, a behemoth six and a half billion times the mass of the Sun, have uncovered a new way these cosmic monsters unleash their power.

In a recent piece for my column The Universe, I wrote about the biggest black holes in the cosmos. These can tip the scales at many billions of times the sun’s mass, outweighing even entire galaxies.

Some things in cosmology may simply be unknowable. Why is there something rather than nothing? What lies outside the universe? What is inside a black hole? That last one has been niggling at ...

At the heart of nearly every galaxy lurks a cosmic giant: a supermassive black hole. These mysterious objects, millions to billions of times more massive than our Sun, exert such powerful gravity that ...

Listen to more stories on the Noa app. To study the origins of our universe is to struggle with profound chicken-or-egg questions. We know the Big Bang happened. Cosmologists can see its afterglow in ...
