The “Euclid Dark Universe Explorer,” a novel space telescope, has triumphantly obtained preliminary test images that hint at the transformative potential of this instrument in deepening our understanding of the cosmos. The promising first images indicate that the telescope is functioning as intended, allowing for adjustments to optimize its performance, and preparing the way for unprecedented scientific discoveries.
These initial images were captured by Euclid’s two instruments. The stunning findings hint at the capability of the space telescope to meet its scientific objectives and perhaps go beyond. As we still have months before Euclid offers its new view of the universe, reaching this stage assures the mission’s scientists and engineers that the telescope and instruments are functioning correctly.
Euclid, a European Space Agency (ESA) mission, aims to observe billions of faint galaxies and probe the roots of the Universe’s accelerating expansion, as well as unravel the mysteries of dark energy, dark matter, and gravity.
The project manager of Euclid, Giuseppe Racca, expressed enormous joy and thrill at seeing the initial images after over 11 years of design and development. The potential that Euclid holds, to ultimately observe billions of galaxies and create the largest 3D sky map ever, is astounding.
ESA’s leadership also expressed their confidence in the mission, appreciating the early performance of Euclid. They look forward to the revelation of the largely unknown parts of the Universe by the mission.
The initial images, already rich in detail, display spiral and elliptical galaxies, stars near and far, star clusters, and more. However, the area covered is merely about a quarter of the width and height of the full moon.
Despite early challenges, such as unexpected light contamination in the initial images, the team has been able to overcome these issues, ensuring that the mission proceeds as planned.
Euclid’s Near-Infrared Spectrometer and Photometer (NISP) instrument will measure the light emitted by galaxies at different wavelengths, providing crucial distance data. This, combined with data on galaxy shapes from the VIS instrument, will allow a map of galaxies’ distribution across the Universe to be created, providing insights into dark matter and dark energy.
These preliminary images, as stunning as they are, serve mainly to validate the instruments and determine how the spacecraft might be refined. The Euclid Consortium will eventually convert the raw, artifact-laden images into artifact-free, detailed, and sharp scientific images.
Over the following months, ESA and industry colleagues will continue testing and checking to ensure Euclid’s optimal operation. Once the commissioning and performance verification phase is concluded, the real science can commence. At that point, a new set of images illustrating the mission’s capabilities will be released by ESA.

Frequently Asked Questions (FAQs) about Euclid Space Telescope
What are the first test images taken by Euclid’s instruments?
The first test images taken by Euclid’s instruments are groundbreaking and indicate that the space telescope will achieve its scientific goals and possibly much more. The two instruments are the VISible instrument (VIS) and the Near-Infrared Spectrometer and Photometer (NISP).
Who are some of the key people involved in the Euclid project?
Key people involved in the Euclid project include Giuseppe Racca, Euclid project manager; Josef Aschbacher, ESA Director General; Carole Mundell, ESA’s Director of Science; Yannick Mellier, Euclid Consortium lead; Mark Cropper, leader of the development of VIS; Reiko Nakajima, VIS instrument scientist; Knud Jahnke and William Gillard, NISP instrument scientists.
What are the primary scientific goals of the Euclid project?
Euclid is a mission to observe billions of faint galaxies and investigate the origin of the Universe’s accelerating expansion, as well as the mysterious nature of dark energy, dark matter, and gravity.
What were the challenges faced by the Euclid team during the initial testing phase?
The initial testing phase faced a scare of an unexpected pattern of light contaminating the images. Investigations suggested that some sunlight was creeping into the spacecraft, probably through a tiny gap. However, this was resolved by avoiding certain angles to fulfill its mission.
When will the ‘real science’ of the Euclid mission begin?
The ‘real science’ of the Euclid mission will begin following the completion of the ‘commissioning and performance verification phase’. At this point, ESA will release a new set of images to demonstrate what the mission is capable of.
