  • Preparing for Euclid’s first images

    Preparing for Euclid’s first images

    Never before has a telescope been able to create such razor-sharp astronomical images across such a large patch of the sky.

    On Tuesday 7 November, ESA will release the first full-colour images captured by its recently launched Euclid space telescope. These images form part of the mission’s ‘Early Release Observations’ – where Euclid was tasked with scrutinising a set of celestial targets chosen for their public appeal and scientific value.

    The five images are full of cosmic secrets waiting to be revealed. And this is just the beginning. During its six-year mission, Euclid will generate the equivalent of a million DVDs of data. These data will be used to create the biggest ever 3D map of the Universe and uncover the secrets of dark matter and dark energy.

    In this video, hear from the experts about how Euclid has reached this milestone. Discover how they felt when they saw the first images, and find out what these images will reveal about the cosmos.

    Watch the reveal of the images live through ESA Web TV or YouTube on 7 November, 13:15 GMT / 14:15 CET. At the same time, an ESA press release including all images will be published at esa.int/euclid.

  • Euclid: Gate to the dark

    Euclid: Gate to the dark

    ESA’s Euclid mission is on a quest to unveil the nature of two elusive ‘dark’ entities. As the renowned theoretical physicist Stephen Hawking remarked in 2013, “The missing link in cosmology is the nature of dark matter and dark energy”.

    During the last 70 years, scientists have made enormous progress in understanding the very initial phases of the Universe and its evolution to the present day. Thanks to advances in observations and theoretical modelling, a clear picture has emerged of how stars form, and how galaxies grow and interact with each other, coming together to form groups and clusters.

    Yet, fundamental mysteries remain. 95% of the Universe appears to be made up of unknown ‘dark’ matter and energy. Dark matter and energy affect the motion and distribution of visible sources but do not emit, reflect or absorb any light. And scientists do not know what these dark entities actually are.

    To address this question, Euclid will create a great map of the large-scale structure of the Universe across space and time by observing with unprecedented accuracy billions of galaxies out to 10 billion light-years. This is not easy, and making sure that Euclid is up to the task has required the expertise and dedication of many people over several years of work.

    This video captures the journey behind the Euclid mission, from a human and intensely visual perspective. It shows tiny screws, winding cables and shiny surfaces in a whole new light, revealing how each piece comes together to form the space telescope. Be drawn in by awe-inspiring photos of the cosmos, and stay for the seemingly choreographed ballet of teamwork necessary to assemble and test the spacecraft, before being swept away by the emotion of the launch into space.

    Euclid’s adventure has begun. With its observations during the coming years, it will help us uncover the missing link in cosmology and open the gate to the ‘dark’ side of the Universe.

  • How Euclid will map the Universe

    How Euclid will map the Universe

    ESA’s Euclid mission will create a 3D-map of the Universe that scientists will use to measure the properties of dark energy and dark matter and uncover the nature of these mysterious components. The map will contain a vast amount of data, it will cover more than a third of the sky and its third dimension will represent time spanning 10 billion years of cosmic history.

    But dealing with the huge and detailed set of novel data that Euclid observations will produce is not an easy task. To prepare for this, scientists in the Euclid Consortium have developed one of the most accurate and comprehensive computer simulations of the large-scale structure of the Universe ever produced. They named this the Euclid Flagship simulation.

    Running on large banks of advanced processors, computer simulations provide a unique laboratory to model the formation and evolution of large-scale structures in the Universe, such as galaxies, galaxy clusters, and the filamentary cosmic web they form. These state-of-the-art computational techniques allow astrophysicists to trace the motion and behavior of an extremely large number of dark-matter particles over cosmological volumes under the influence of their own gravitational pull. They replicate how and where galaxies form and grow, and are used to predict their distribution across the celestial sphere.

    Explore the Euclid Flagship simulation in this video and get a sneak preview of the structure of the dark Universe, as we currently model it. New insights will be brought to you by the Euclid mission in the coming years.

  • Euclid | Launch to ‘L2’

    Euclid | Launch to ‘L2’

    If you think its only possible be held in orbit around a central body of mass – say a planet or a star – you’d be wrong. It is in fact possible to orbit around an invisible point, an oasis of forces, infinitesimal in size. ESA’s Euclid mission was launched on 1 July 2023 to uncover the secrets of the dark universe. Its destination? Like many astronomy missions before it, Lagrange point 2.

    ‘L2’ is an ideal location for astronomy missions because they can keep the Sun, Earth and Moon behind them at all times, so they don’t interfere with observations, while at the same time getting a clear view of deep space and pointing an antenna back to Earth to remain in close communication. The permanent sunlight on Euclid at L2 also keeps the telescope thermally stable, allowing for the extremely high stability required for the instrument’s long exposure observations.
    Euclid’s orbit around Lagrange point 2 is big. In terms of distance, the ‘radius’ of Euclid’s orbit varies from about 400 000 kilometres at its closest to the centre, and up to 800 000 kilometres at its furthest. By the time Euclid has completed one full revolution around L2, the Moon will have circled the Earth six times.

    The reason for this large orbit is that it is almost free, in terms of fuel, to get there. The better the accuracy of the rocket that launches a mission into such a large halo orbit around L2, the less fuel that’s needed to perform correction manoeuvres – and Euclid only required a tiny correction manoeuvre after its near-perfect launch on a Space X Falcon 9.

    This animation, created using “Gaia Sky”, shows Euclid’s path from Earth to this unique and useful position in space. Located about 1.5 million kilometres from Earth in the opposite direction from the Sun, the second Lagrange point (or Libration point) is about four times further away than our Moon.

    Euclid will spend about a month getting to ‘L2’ followed by a planned six years in orbit, from where it will study the mysterious nature of dark matter and dark energy, that make up 95% of our Universe, but about which very little is known.

    We are on our way to uncover the dark Universe!! 🚀 #shorts

    ESA’s latest astrophysics mission, Euclid, lifted off on a Space X Falcon 9 from Cape Canaveral in Florida, USA, at 17:12 CEST on 1 July 2023.

    Euclid has now started its month-long journey to Sun-Earth Lagrange point L2, located 1.5 million kilometres from Earth, in the opposite direction from the Sun.

    The telescope will survey one third of the sky with unprecedented accuracy and sensitivity. By observing billions of galaxies out to 10 billion light-years, it will create the most extensive 3D-map of the Universe, with the third dimension representing time.

    ESA’s Euclid mission is designed to explore the composition and evolution of the dark Universe. Euclid will chart how the Universe has expanded and how large-scale structure is distributed across space and time, revealing more about the role of gravity and the nature of dark energy and dark matter.

    Four weeks after launch, Euclid will enter its orbit around L2. Once in orbit, mission controllers will start the activities to verify all functions of the spacecraft, check out the telescope and finally turn the instruments on.
    Following this, scientists and engineers will be engaged in an intense two-month phase of testing and calibrating Euclid’s scientific instruments, and preparing for routine observations. The telescope begins its early phase of the survey of the Universe three months after launch.

  • Euclid | ESA’s mission into the unknown

    Euclid | ESA’s mission into the unknown

    ESA’s Euclid mission is designed to bring the dark side of the Universe to light. Based on the way galaxies rotate and orbit one another, and the way in which the Universe is expanding, astronomers believe that two unseen entities dominate the composition of our cosmos. They call these mysterious components dark matter and dark energy, yet to date we have not been able to detect either of them directly, only inferring their presence from the effects they have on the Universe at large.

    To better understand what dark matter and dark energy may be, we need a mission that can more closely reveal what effects they have had on galaxies, galaxy clusters and the expansion of the Universe itself. Euclid is that mission.

    ESA’s Euclid mission will create a 3D-map of the Universe, with the third dimension representing time itself. The further away a galaxy is located, the longer its light has taken to reach us and so the earlier in cosmic history we will see it. By observing billions of galaxies out to a distance of 10 billion light-years, scientists will be able to chart the position and velocity of galaxies over immense distances and through most of cosmic history, and trace the way the Universe has expanded during that time. Euclid’s extraordinary optics will also reveal subtle distortions in the appearance of galaxies.

    From this wealth of new data, astronomers will be able to infer the properties of dark energy and dark matter more precisely than ever before. This will help theorists pin down the nature of these mysterious components and develop a refined understanding of how gravity behaves at the largest distances.
