We May Have Found the First Stars Born After the Big Bang

Determination of the mass distribution of the first stars from the 21-cm signal

The formation of the first stars and the subsequent population of X-ray binaries represents a fundamental transition in the state of the Universe as it evolves from near homogeneity to being abundant in collapsed structures such as galaxies. Due to a lack of direct observations, the properties of these stars remain highly uncertain. Here, by considering the impact of the first stars and their remnant X-ray binaries on the cosmological 21-cm sign…

We May Have Found the First Stars Born After the Big Bang

Painstaking new work suggests that the burning balls of gas started forming about 180 million years after the cosmos burst into being.

Scientists discovered bizarre radio signal from 13,000,000,000 years ago and it could answer how the universe started

Scientists have discovered a radio signal which could show how the stars in the universe came out.

Radio signal from the very early universe offers clues about the first stars

Understanding how the universe transitioned from darkness to light with the formation of the first stars and galaxies is a key turning point in the universe's development, known as the Cosmic Dawn. However, even with the most powerful telescopes, we can't directly observe these earliest stars, so determining their properties is one of the biggest challenges in astronomy.
