Ultimately, the creation of this 3D map will provide profound insights into the nature of dark matter and dark energy, unraveling some of the universe's most mysterious and captivating secrets. Through this mapping, we can observe how this distribution evolves over time. The fusion of distance data obtained by NISP with galaxy shape measurements from VIS will allow us to create a comprehensive map of the distribution of galaxies throughout the vast expanse of the Universe. This second role is crucial as it enables us to determine the distance to each galaxy directly. Firstly, it captures infrared light images of galaxies, and secondly, it measures the emitted light from galaxies across different wavelengths. The image we have now was taken at an orientation where sunlight interference was not an issue.Įuclid’s Near-Infrared Spectrometer and Photometer (NISP)Įuclid's Near-Infrared Spectrometer and Photometer (NISP) instrument serves a dual purpose in its mission. By avoiding these angles, Euclid's VIS will be able to execute its mission effectively. However, the team's quick thinking allowed them to realize that this light interference occurred only at specific orientations. After thorough investigations, it was determined that some sunlight had infiltrated the spacecraft, likely through a minute gap. They detected an unexpected pattern of light contaminating the images.
The uniqueness of this image is further underscored by an initial concern faced by the Euclid team when activating the instrument.

Remarkably, the image covers only about a quarter of the width and height of the full Moon, yet it is rich in detail and potential discoveries.
While a few galaxies are readily identifiable, many others appear as indistinct blobs amid the stars, eagerly awaiting Euclid's future unveiling. In the first image obtained, we catch a glimpse of the wealth of data that VIS will provide. “Our teams have worked tirelessly since the launch of Euclid on 1 July and these first engineering images give a tantalising glimpse of the remarkable data we can expect from Euclid.” - Carole Mundell, ESA’s Director Of Science Euclid’s VISible instrument (VIS)Įuclid's Visible Instrument (VIS) is designed to capture incredibly sharp images of billions of galaxies, allowing precise measurements of their shapes. I have full confidence that the team behind the mission will succeed in using Euclid to reveal so much about the 95% of the Universe that we currently know so little about.” - Josef Aschbacher, ESA Director General “It is fantastic to see the latest addition to ESA’s fleet of science missions already performing so well. The fully calibrated Euclid will ultimately observe billions of galaxies to create the biggest ever 3D map of the sky.” - ,” Giuseppe Racca, Euclid Project Manager
“After more than 11 years of designing and developing Euclid, it’s exhilarating and enormously emotional to see these first images.It’s even more incredible when we think that we see just a few galaxies here, produced with minimum system tuning. Months before the long-anticipated Euclid Telescope delivers its groundbreaking view of the cosmos, scientists and engineers involved in the mission are already celebrating a significant milestone as the telescope and instruments have proven to be in excellent working condition.
