In the dense environment of the early universe, dark matter particles would collide with, and annihilate, each other, ...

Most events in the universe are not fully understood, including the relatively simple process of star formation. Stars form in dense clouds of cold gas and dust. When these clouds reach a threshold ...

"This gives us a new way to rule out certain black hole scenarios for dark matter." New research suggests that primordial black holes created during the Big Bang could have played a major role in ...

Oftentimes, we think of space as an endless, mostly empty vacuum, a silent backdrop where planets, stars, and galaxies play out their dance. We also think of time as something separate, a steady ...

Astronomers using the James Webb telescope may have discovered some of the universe's first stars, and they may offer clues to how galaxies form. Using the James Webb Space Telescope (JWST) and a ...

A computational model of the early-to-present-day Universe predicts that some of the first stars formed in structures that challenge conventional classification. Read the paper: The emergence of ...

Artist’s impression of the powerful winds blowing from the bright X-ray source GX13+1. The X-rays are coming from a disc of hot matter, known as an accretion disc, that is gradually spiralling down to ...

We may have finally seen the first generation of stars. Astronomers have been looking for these primordial behemoths, called Population III stars, for decades. Now they have found what may be the most ...

Scientists working with the James Webb Space Telescope discovered three unusual astronomical objects in early 2025, which may be examples of dark stars. The concept of dark stars has existed for some ...

Alexey A Petrov receives funding from the US Department of Energy. Scientists working with the James Webb Space Telescope discovered three unusual astronomical objects in early 2025, which may be ...
