James Webb has peered into the distant Universe.
James Webb has spotted extremely distant galaxies formed soon after the Big Bang, but are they old or young? Or is this the wrong question to ask?
It’s the oldest light in the universe.

The Hubble Space Telescope could gaze back 13.4 billion years, and with the JWST we expect to improve on this possibly to 13.55 billion years.
Time ends when the universe does.
The evolution of the cosmos after the Big Bang.
Some argue the Big Bang was a rebirth rather than a birth.
Flouride is created by Wolf–Rayet stars, here seen in the Milky Way by the Hubble Space Telescope.
Tracing the cosmic origin of toothpaste, scientists got a glimpse into the surprising chemistry of early galaxies.
Hubble took pictures of the oldest galaxies it could – seen here – but the James Webb Space Telescope can go back much farther in time.
The James Webb Space Telescope is set to launch into orbit in December 2021. Its mission is to search for the first light to ever shine in the universe.
What happened during the Big Bang?
How scientists are planning to listen to the sound of the big bang with a gravitational wave detector that would fit in a kitchen.

A small add-on to existing gravitational wave detectors could reveal what happens to matter as it becomes a black hole, a process like the big bang in reverse.
No one knows what kicked off the Big Bang that eventually allowed the stars to begin forming.

The term ‘Big Bang’ might make you think of a massive explosion. Put the thought out of your head. Rather than an explosion, it was the start of everything in the universe.

Scientists who discovered planets in far off stellar systems and the fundamentals of the Big Bang Theory have earned the 2019 Nobel Prize in Physics.
The Princeton cosmologist helped pioneer our current model of the universe and began a whole new branch of physics.

Long ago in the distant past, our entire Universe was microscopic – just like an atom – and obeyed completely different rules of cause and effect.

Helium lifts balloons and makes our voices squeak. But its supply on Earth is finite and is critical for modern industrial processes and medical imaging in hospitals. How worried should we be?
Galaxy history revealed by the Hubble Space Telescope.
From a mysterious energy of empty space to parallel universes, cosmology’s view of ‘nothing’ is anything but boring.
Big History may provide a basis for drawing different human cultures closer together.
At a time when nationalism and religious ideologies are dividing humanity, it is important to find unifying perspectives on our ‘origin story.’
About a century ago, we didn’t even know that galaxies existed.

Pretty much as soon as we understood what galaxies were, we realised they are all moving away from each other. And the ones that are further away are moving faster. In short, the universe is expanding.
UK’s Astronomer Royal Martin Rees shares his memories of the physicist Stephen Hawking, who has died at the age of 76.

Signals from the first stars to form in the universe have been picked up by a table-sized detector in a west Australian desert. The find also hints at an early interaction with dark matter.
Timeline of the universe.
From blindingly bright and burning hot to pleasantly ‘candle-lit’, the first years of the universe would have been spectacular to see.
