We Finally Know What Turned The Lights on at The Dawn of Time

According to data from the Hubble and James Webb Space Telescopes, the origins of the free-flying photons in the early cosmic dawn were small dwarf galaxies that flared to life, clearing the fog of murky hydrogen that filled intergalactic space.

Webb sees carbon-rich dust grains in the first billion years of cosmic time

This observation suggests exciting avenues of investigation into both the production of cosmic dust and the earliest stellar populations in our Universe, and was made possible by Webb’s unprecedented sensitivity.

The universe was five times slower soon after the Big Bang

Scientists have for the first time observed the early universe running in extreme slow motion, unlocking one of the mysteries of Einstein's expanding universe. 

Webb Telescope Tracks Universe's First Light

New results from the James Webb Space Telescope find that radiation from ordinary galaxies cleared the primordial haze left over from the Big Bang, allowing the first light to shine through the early universe.

New Dark Matter Theory Says a "Dark Big Bang" Created the Hidden Universe

There could have been two scenarios with the two Big Bangs. The Hot Big Bang, as in the standard picture, creates the hot plasma of visible matter and radiation and the dark matter, however, could have been created in a later, ‘darker’ Big Bang.

James Webb Space Telescope finally on its way to discovery

A powerful European Ariane 5 rocket boosted NASA’s $10 billion James Webb Space Telescope into space on Christmas Day, kicking off a great attempt to capture light from the first galaxies to form in the aftermath of the Big Bang.

The Lifetime of a Neutron Has Been Measured in Space

For the first time, scientists have measured the lifespan of a neutron in the void of space. This could help us to better understand how quickly elements formed out of the particle soup that filled the Universe just after the Big Bang.

Quantum structures in super-chilled helium may mirror early universe

For the first time, researchers have documented the long-predicted occurrence of 'walls bound by strings' in superfluid helium-3. The existence of such an object may explain how the universe cooled down.

Fossil from the Big Bang discovered

A relic cloud of gas, orphaned after the Big Bang, has been discovered in the distant universe by astronomers using the world's most powerful optical telescope, the W. M. Keck Observatory on Maunakea, Hawaii.

Scientist finds elusive star with origins close to Big Bang

The discovery of this approximately 13.5 billion-year-old tiny star means more stars with very low mass and very low metal content are likely out there—perhaps even some of the universe's very first stars.

Dark Matter and Energy Are Real Reveals Final Data of Planck Mission

The Planck mission launched in 2009 has finally reached its ending point. So far the standard model of cosmology has survived all the tests.

Star formation underway 250 million years after Big Bang

Astronomers have observed a galaxy 13.3 billion light years away that includes stars that must have been shining just 250 million years after the Big Bang.

Stephen Hawking's final theory about the big bang

The theory, which was submitted for publication before Hawking's death earlier this year, is based on string theory and predicts the universe is finite and far simpler than many current theories about the big bang say.

The most distant supermassive black hole ever observed

This black hole resides in a luminous quasar and its light reaches us from when the Universe was only 5 percent of its current age — just 690 million years after the Big Bang.

New Calculation Could Spell Trouble For a Popular Theory of the Universe's Origin

When running Hawking and Hartles’ as well as Vilenkin’s, math, the new team didn’t get the teeny quantum fluctuations required to create today’s universe.
