In short, more redshift means something is further away from Earth.įurther (2) closer to the center of the image is a bright galaxy with a redshift of z = 1.05. Fear not, however, because JWST can also collect this “invisible” light, which is why it promises to reveal the “unfiltered universe” – a phrase you may have seen online. It is named after the fact that as a glowing object moves away from our point of view, the light it emits gets redder and redder… and redder, eventually falling into the infrared region of the electromagnetic spectrum and becoming invisible to the human eye. Redshift is essentially a way for astronomers to measure how far and therefore an object is in the past. Leveįirst, (1) at the top left is a spiral galaxy emitting a redshift of z = 0.16. Below are close-ups of some highlights on the mosaic.

This is the full schematic of the CEERS Epoch 1 image.

According to the CEERS team, there are six main attractions. Okay, now that you’ve successfully accessed the image, let’s discuss some of the highlights. Because of how big this file is, your mobile phone may start to act up. You can download a medium or high-res version of the image here, but if you’re shooting for the latter, which I did, CEERS recommends using a computer or laptop.

“Era 1 covers less than half of our total field of view in the sky, and the images already acquired have led to new discoveries and an unexpected, but not undesirable abundance of previously unseen galaxies,” the CEERS team said in a press release. The climactic mosaic consists of 690 individual frames taken with the JWST near-infrared camera and will be built from observations scheduled for December. You can recognize some of them on Twitter due to my inability to remain silent ? /cJsVyXwuqLįor the context of how perfectly big This is the final image, the team explains that it covers an area about eight times larger than JWST’s first deep field, released on July 11, which was already mind-blowingly huge. I pulled out some of my favorite (I was limited to 6, that was rough) galaxies and regions to highlight. I’ve spent *time* just scrolling and looking at this picture for the past weeks.
