There is a space telescope.
The North Ecliptic Pole is featured in one of the first medium-deep wide-field images of the universe. The image is from the Prime Extragalactic Areas for Reionization and Lensing Science program.
"Medium-deep" refers to the faintest objects that can be seen in this image, which are about 29th magnitude (1 billion times fainter than what can be seen with the eyes), while "wide-field" refers to the total area that will be covered by the program.
The image has eight different colors of near-IR light captured by the Near-Infrared Camera and three different colors of visible light from the Hubble Space Telescope. Many of the stars that were previously unseen by Hubble or the largest ground-based telescopes are visible in this beautiful color image.
The team will be able to find faint objects with emission lines that can be used to estimate their distances with the help of the NIR cam observations.
While analyzing this field, members of the PEARLS team shared their thoughts and reactions.
Over the course of two decades, I've worked with a large international team of scientists to prepare our program. The images are beyond my expectations. They allow me to measure the total amount of light produced and the number of stars in the sky.
Rolf was blown away by the first PEARLS images. When I selected this field near the North Ecliptic Pole, I didn't know that it would yield such a treasure trove of distant galaxies. I can see the leftovers of their building blocks in the stars outside.
Jake said the images far exceed what he expected from his simulations. I was surprised by the high resolution. There are a lot of objects that I didn't think we would be able to see.
The history of the universe is affected by the diffuse light that Imeasured in front of and behind stars. I'm very lucky to be starting my career now. I'm really excited about the opportunities and challenges that the data offers.
"I spent many years designing the tools to find and accurately measure the brightnesses of all objects in the new Webb PEARLS images, and to separate foreground stars from distant galaxies." The telescope's performance has exceeded all my expectations and allowed for unforeseen discoveries.
The PEARLS images were assembled into large mosaics and the image quality was out of this world. The PEARLS field allows us to get a glimpse of very rare galaxies at the dawn of the universe.
"I hope that this field will be monitored throughout the mission, so that we can see objects that move, vary in brightness, or briefly flare up."
It will be possible to find time-variable objects like exploding supernovae and bright accretion gas around black holes in active galaxies, which should be visible to larger distances than ever before.
The time-domain legacy, area covered, and depth reached can only get better with time.
