The newly-discovered core-collapse supernova, seen at a lookback time of approximately 11.5 billion years, is strongly lensed by a member galaxy in the massive galaxy cluster Abell 370.

Think of bringing a pot of water to the boil: As the temperature reaches the boiling point, bubbles form in the water, burst and evaporate as the water boils. This continues until there is no more water changing phase from liquid to steam.

Discover how oscillons, formed after the Big Bang, hold the key to unlocking the secrets of our cosmic origins.

The seven galaxies highlighted in this Webb image have been confirmed to be at a distance that astronomers refer to as redshift 7.9, which correlates to 650 million years after the Big Bang.

In the middle of the last century, physicists found that protons can resonate, much like a ringing bell. Advances over the last three decades have led to 3D pictures of the proton and significant insight into its structure in its ground state. But little is known about the 3D structure of the resonating proton.

Some galaxies are choked with so much opaque dust they become … Dark Galaxies (dun dun dunnnnn).

Astronomers using the X-SHOOTER instrument at ESO's Very Large Telescope (VLT) have detected light from a gamma-ray burst at a redshift of 6.3, meaning

Researchers say gravitational waves could have been so strong in the early universe that gravity itself was able to create light.

Two distant galaxies observed by the James Webb Space Telescope have offered insight into the formation of galaxies after the Big Bang.

Using the Atacama Large Millimeter/submillimeter Array and the Subaru Telescope, astronomers have discovered a pair of merging gas-rich galaxies that existed 12.8 billion years ago.

In the early universe, the gas between stars and galaxies was opaque—energetic starlight could not penetrate it. But 1 billion years after the big bang, the gas had become completely transparent. Why? New data from NASA's James Webb Space Telescope has pinpointed the reason: The galaxies' stars emitted enough light to heat and ionize the gas around them, clearing our collective view over hundreds of millions of…

Astronomers have detected polycyclic aromatic hydrocarbons in SPT-S J041839-4751.9 (SPT0418-47 for short), a galaxy observed less than 1.5 billion years after the Big Bang.

The James Webb Space Telescope continues to throw up surprises, and recently it has been used to spot some very old galaxies which have astonished astronomers.

Astronomers using the NASA/ESA/CSA James Webb Space Telescope have spotted early galaxies with stellar bars at a time when the Universe was a mere 25% of its present age.

The newly-discovered blue supergiant is much hotter than the Sun, and existed when the Universe was about 2.6 billion years old.

Only a few hundred million years after the Big Bang, the infant Universe was brimming with opaque hydrogen gas that trapped light at some wavelengths from stars and galaxies.

Astronomers using the NASA/ESA/CSA James Webb Space Telescope have discovered three ultra-massive galaxies -- nearly as massive as our own Milky Way Galaxy -- already in place within the first billion years after the Big Bang.

Abstract. Deep space observations of the James Webb Space Telescope (JWST) have revealed that the structure and masses of very early Universe galaxies at high r

A new image from the James Webb Space Telescope captured more than 45,000 baby galaxies, at a time when our universe was less than 600 million years old. The post Glimpse 45,000 baby galaxies in the early universe first appeared on EarthSky.

Astronomers using the NASA/ESA/CSA James Webb Space Telescope have observed six candidate galaxies with stellar masses as high as 1011 solar masses about 500-700 million years after the Big Bang.
