Webb is taking us on an incredible journey back in time! ⌛️

@esawebb has unveiled 10 times more supernovae in the early Universe than ever known before. These findings include the most distant exploding stars used to measure the Universe’s expansion rate.

In the first three images, we see Webb’s deep space imagery with hundreds of celestial objects of various shapes, sizes, and colors. Among these, 83 of the smaller objects are circled in green. 

To discover the supernovae, the team compared multiple images taken up to one year apart and looked for sources that disappeared or appeared in those images. These objects that vary in observed brightness over time are called transients, and supernovae are a type of transient. In all, the team uncovered 79 supernovae in a patch of sky only about the thickness of a grain of rice held at arm’s length. These transients, or objects that change brightness over time, are the key to unveiling the Universe’s past.

Prior to Webb, only a few supernovae were found above a redshift of 2, which corresponds to when the universe was only 3.3 billion years old — just 25% of its current age. But now, the team has discovered supernovae from when the Universe was less than 2 billion years old, showing us a glimpse of the Universe in its “teen” or even “pre-teen” stages. 

Image four provides a closer look at these supernova discoveries. Here where have six different observations of three galaxies. Arrows point out bright blobs visible in one observation but not the other, indicating the presence of these transient supernovae. This comparison over time reveals the stars that have exploded, providing a deeper understanding of the Universe’s early years.

Swipe through to see these groundbreaking images.
