A paper published in 2024 theorizes that time may have existed before the Big Bang, but we're still not entirely sure.

This first light, as it's called, shows that all of the spacecraft's systems are working just as expected. "Based on the ...

The gist of the theory is that, back in the day — well, literally at the beginning of time and space, the “big bang” — the ...

Astronomers using the James Webb Space Telescope have discovered the most distant quiescent galaxy ever seen – one that had ...

They have shorter or longer wavelengths than visible light. After the Big Bang, the whole Universe was flooded with incredibly bright light. As the Universe has expanded, that light has stretched ...

In this image, three wavelengths of light have been combined ... capturing the afterglow of the Big Bang that radiated throughout the cosmos. The Atacama Cosmology Telescope (ACT) released the ...

So far, nobody's been able to see past it to the Big Bang. As it turns out ... with a sensitive telescope tuned to see millimeter-wavelength light," he said, pointing out that the observations ...

It can observe at redder wavelengths than its predecessor, the Hubble Space Telescope, and it has extended the frontier of galaxy detection to less than 300 million years since the Big Bang 3.

The first galaxies in the Universe were born enshrouded in a “foggy” gas, and could not be seen clearly until they had cleared up this fog. Using the James Webb Space Telescope, a team of researchers ...
