early Universe

Spectroscopic observations reveal that Maisie’s galaxy, named after Steven Finkelstein’s daughter, was detected 390 million years after the Big Bang. That makes it one of the four earliest confirmed galaxies ever observed.

Astronomers confirm Maisie’s galaxy is among earliest ever observed

Quasar ‘clocks’ show Universe was five times slower soon after the Big Bang

The galaxy observed by Webb shows an Einstein ring caused by a phenomenon known as lensing, which occurs when two galaxies are almost perfectly aligned from our perspective on Earth. The gravity from the galaxy in the foreground causes the light from the background galaxy to be distorted and magnified, like looking through the stem of a wine glass. Because they are magnified, lensing allows astronomers to study very distant galaxies in more detail than otherwise possible.

Webb images challenge theories of how universe evolved

The HERA radio telescope, located in Karoo in South Africa, consists of 350 dishes pointed upward to detect radio waves from the early universe.
