A treasure trove of data from the Euclid spacecraft, including significant contributions from UK scientists, has unveiled the largest images of the Universe ever captured from space. The release marks a milestone in the quest to understand dark matter and dark energy.
Unveiling the Dark Universe
A significant breakthrough in space exploration has emerged from the European Space Agency’s Euclid mission. Launched in July 2023, the mission aims to map the ‘dark Universe’ by observing two billion galaxies to create a comprehensive 3D map. UK scientists have played a pivotal role in this mission, contributing to the release of the largest space images ever taken.
The Significance of the Euclid Mission
The Euclid mission is dedicated to uncovering the mysteries of dark matter and dark energy, which comprise most of the Universe but remain poorly understood. The data released, stemming from only 24 hours of observations, offers a glimpse into the immense potential of Euclid in studying the cosmos.
Dr. Caroline Harper, Head of Space Science at the UK Space Agency, emphasized the mission’s importance:
“A key part of our purpose as a space agency is to understand more about the Universe, what it’s made of and how it works. The Euclid mission epitomizes this quest.”
Contributions from UK Scientists
UK scientists have been integral to the Euclid mission, contributing significantly to its early results. Among the notable contributions is a paper by Professor Mark Cropper from UCL Mullard Space Science Laboratory.
Over 16 years, he led the development of the VIS optical camera, one of the largest ever sent into space, supported by £20 million of UK Space Agency funding.
Professor Mark Cropper remarked:
“These are the largest images of the Universe ever taken from space, covering large swathes of the sky in fine detail. They demonstrate Euclid’s wide-ranging potential.”
Exploring the Perseus Cluster
Another groundbreaking paper from Professor Nina Hatch at the University of Nottingham examines the Perseus Cluster, a group of galaxies 240 million light-years away. This cluster is crucial for understanding dark matter, as its formation relies on the presence of this elusive substance.
Professor Nina Hatch highlighted a surprising discovery:
“Euclid’s images of the Perseus Cluster revealed a faint glow between the galaxies, known as intracluster light. This light can help us map dark matter if we understand where the intracluster stars came from.”
Technological Marvel: The VIS Optical Camera
The VIS optical camera is a technological marvel, requiring exquisite precision and stability to achieve Euclid’s core aims. The UK’s contribution to this instrument underscores its commitment to pioneering space science.

The Role of the UK in Data Processing
The UK’s involvement extends beyond instrument development. It plays a significant role in the Euclid Science Ground Segment, processing data from the telescope into science-ready products. A consortium of UK universities, led by the University of Edinburgh, provides critical data processing pipelines.
Professor Andy Taylor from the University of Edinburgh noted:
“These new images from Euclid are stunning. They demonstrate both the image quality and the huge area of the sky seen by Euclid in each observation.”
Industrial Contributions and International Collaboration
Teledyne e2v, based in Chelmsford, provided the telescope’s Charged Couple Device detectors, crucial for capturing high-resolution images. This collaboration highlights the synergy between industry and academia in advancing space science.
Antonio Spatola, Director of Business Development and Sales at Teledyne e2v, expressed pride in their contribution:
“We are privileged to contribute enabling technology to this important science mission.”
A Step Forward in Cosmic Understanding
The Euclid mission represents a remarkable achievement in space exploration and a significant step forward in our understanding of the dark Universe. UK scientists and institutions have demonstrated excellence in contributing to this mission, showcasing the nation’s leadership in space science and technology.
As the Euclid mission continues, the data and images it provides will be instrumental in answering fundamental questions about the Universe’s composition and evolution. The collaboration and dedication of scientists and engineers across the globe underscore the importance of international efforts in uncovering the secrets of the cosmos.
