Helium hydride’s origin also marked the beginning of a chain reaction that led to the formation of molecular hydrogen (H2), ...

A new study has found a few odd surprises about the first molecule in the universe, suggesting our models of the early cosmos ...

A new theory promises to simplify our approach to the universe's earliest moments, but some cosmologists say further mathematical scrutiny is warranted.

"Theories involving substantial formation of stars prior to or together with the black hole formation and growth are very ...

Jun 20, 2025 Cosmic signal from the very early universe will help astronomers detect the first stars Astronomers have shown that we will be able to learn about the masses of the earliest stars by ...

“We have produced two images of the very early universe from a time long before there were any stars and galaxies – when all of space was filled with an almost perfectly uniform mixture of hydrogen ...

Images from the James Webb Space Telescope show six bright red dots that scientists believe are distant galaxies from the early universe. But they're unlike any galaxies we've seen so far.

This incredible interactive map, dubbed COSMOS-Web, lets you scroll through 800,000 galaxies and peer back as far as 13.5 billion years.

They also closely match measurements based on properties of the early universe, such as those obtained by the Planck satellite, which took measurements between 2009 and 2013.

They could be very, very dense, highly star-forming galaxies. "Or they could be highly accreting supermassive black holes from the very early universe," said Mockler, who is an incoming professor at ...
