So much happened in the earliest moments of the universe. Elementary particles appeared, the first nuclei of hydrogen and ...

Led by doctoral student Tatsuya Kotani and Professor Tomoharu Oka from Keio University, the research team measured the ...

Scientists may have identified the gravitational waves that make up some of the universe’s background, not just those coming from unusual events like black hole collisions. New Atlas reports that the ...

The Big Bang theory has dominated our understanding of the universe’s origin for almost 100 years. It describes a moment when ...

Many space-lovers know the phrase "We are all made of star stuff." And it's true - our planet formed from the dust cloud left over from the formation of our Sun, and from the planet, all life. That ...

Our view of a small region of the Universe near the northern galactic cap, where each pixel in the image represents a mapped galaxy. On the largest scales, the Universe is the same in all directions ...

The fabric of the universe is constantly rippling, according to astronomers who have discovered a background buzz of gravitational waves. These waves may be produced by supermassive black holes ...

According to the equations that govern black holes, the larger one of these cosmic behemoths is the lower its average density – given that the universe contains a lot of relatively empty space, could ...

Most explanations rely on "dark energy" to explain the Universe's accelerating expansion rate, but a new study takes a different path.

Such an exponential expansion may seem minor, but it is equivalent to a grape in the palm of your hand swelling to become ...

The detection of a predicted universal background of gravitational waves rippling across the fabric of space-time was announced last Wednesday by the NANOGrav consortium of over 190 scientists at more ...
