One of the first images captured by Euclid shows the Perseus cluster, a group of thousands of galaxies located 240 million light-years from Earth. The closest galaxies appear as swirling structures while hundreds of thousands of background galaxies are visible only as points of light.<\/div>\n

The new images from the Euclid mission include a cluster of thousands of distant galaxies, demonstrating the spacecraft\u2019s unique abilities.\u00a0<\/em><\/p>\n

The Euclid mission, which will investigate the mysteries of dark matter and dark energy<\/a>, released its first five science images<\/a> Tuesday, Nov. 7 The observatory, led by ESA (European Space Agency) with NASA contributions, is scheduled to begin regular science operations in early 2024.<\/p>\n

The new images include views of a large cluster of thousands of distant galaxies, close-ups of two nearby galaxies, a gravitationally bound group of stars called a globular cluster, and a nebula (a cloud of gas and dust in space where stars form) \u2013 all depicted in vibrant colors.<\/p>\n

\u201cThe Euclid observatory will uncover a treasure trove of scientific discoveries that will be used across the world, including by U.S. scientists, for years to come,\u201d said Nicola Fox, associate administrator, Science Mission Directorate, at NASA Headquarters in Washington. \u201cTogether, NASA and ESA are paving the way for a new era of cosmology for NASA\u2019s forthcoming Nancy Grace Roman Space Telescope<\/a>, which will build upon what Euclid learns and will additionally survey objects on the outskirts of our solar system, discover thousands of new planets, explore nearby galaxies, and more.\u201d<\/p>\n

The spiral galaxy IC 342, located about 11 million light-years from Earth, lies behind the crowded plane of the Milky Way: Dust, gas, and stars obscure it from our view. Euclid used its near-infrared instrument to peer through the dust and study it.<\/div>\n

Euclid launched on July 1<\/a> from Cape Canaveral, Florida, then traveled nearly 1 million miles to its vantage point. Following a period of commissioning (testing of the instruments and other components), the space telescope is performing as expected.<\/p>\n

NASA\u2019s Jet Propulsion Laboratory in Southern California delivered critical hardware<\/a> for one of the Euclid spacecraft\u2019s instruments. In addition, NASA has established a U.S.-based Euclid science data center, and NASA-funded science teams will join other Euclid scientists in studying dark energy, galaxy evolution, and dark matter. The agency\u2019s Nancy Grace Roman mission will also study dark energy \u2013 in ways that are complementary to Euclid. Mission planners will use Euclid\u2019s findings to inform Roman\u2019s dark energy work.<\/p>\n

Surveying the Dark Universe<\/strong><\/h2>\n

During its planned six-year mission, Euclid will produce the most extensive 3D map of the universe yet, covering nearly one-third of the sky and containing billions of galaxies up to 10 billion light-years away from Earth.<\/p>\n

The galaxy NGC 6822 is located 1.6 million light-years from Earth. Euclid was able to capture this view of the entire galaxy and its surroundings in high resolution in about one hour, which isn\u2019t possible with ground-based telescopes or targeted telescopes (such as NASA\u2019s Webb) that have narrower fields of view.<\/div>\n

To do this, Euclid needs a wide field of view, which enabled these new images covering a relatively large area. In this way, Euclid differs from targeted observatories like NASA\u2019s James Webb Space Telescope<\/a> that focus on a smaller area of the sky at any one time but typically offer higher-resolution images. Wide-field observatories like Euclid can observe large sections of the sky much faster than targeted telescopes. In addition, Euclid has high resolution compared to previous survey missions, which means it will be able to see more galaxies in each image than previous telescopes.<\/p>\n

For example, Euclid\u2019s wide view was able to capture the entirety of the Perseus galaxy cluster, and many galaxies beyond it, in just one image. Located 240 million light-years from Earth, Perseus is among the most massive structures known in the universe. Euclid\u2019s full survey will ultimately cover an area 30,000 times larger than this image.<\/p>\n

The Horsehead Nebula, also known as Barnard 33, is part of the Orion constellation. About 1,375 light-years away, it is the closest giant star-forming region to Earth. With Euclid, which captured this image, scientists hope to find many dim and previously unseen Jupiter-mass planets in their celestial infancy, as well as baby stars. Full image here.<\/div>\n

The telescope\u2019s survey approach is necessary to study dark energy, the mysterious driver behind our universe\u2019s accelerating expansion. While gravity should pull everything in the universe together, everything is instead moving apart faster and faster. \u201cDark energy\u201d is the term scientists use for this unexplained expansion.<\/p>\n

To study the phenomenon, scientists will map the presence of another cosmic mystery, dark matter. This invisible substance can be observed only by its gravitational effect on \u201cregular\u201d matter and objects around it, like stars, galaxies, and planets. Dark matter is five times more common in the cosmos than regular matter, so if dark energy\u2019s expansive influence on the universe has changed over time, the change should be recorded in how dark matter is distributed on large scales across the universe, and Euclid\u2019s 3D map should capture it.<\/p>\n

No other telescope can capture an entire globular cluster in a single observation and distinguish so many stars within it.<\/div>\n

\u201cEuclid\u2019s first images mark the beginning of a new era of studying dark matter and dark energy,\u201d said Mike Seiffert, Euclid project scientist at JPL. \u201cThis is the first space telescope dedicated to dark universe studies, and the sheer scale of the data we\u2019re going to get out of this will be unlike anything we\u2019ve had before. These are big mysteries, so it\u2019s exciting for the international cosmology community to see this day finally arrive.\u201d<\/p>\n

NASA\u2019s Roman mission will study a smaller section of sky than Euclid, but it will provide higher-resolution images of hundreds of millions of galaxies and peer deeper into the universe\u2019s past, providing complementary information. Scheduled to launch by May 2027.<\/p>\n

The data from the new Euclid images is now available to the scientific community, and scientific papers analysing that data are expected to follow. As the mission progresses, Euclid\u2019s bank of data will grow. New batches will be released once per year and will be available to the global scientific community via the Astronomy Science Archives<\/a> hosted at ESA\u2019s European Space Astronomy Centre in Spain.<\/p>\n

More About the Mission<\/strong><\/h2>\n

Euclid is a European mission, built and operated by ESA, with contributions from NASA. The Euclid Consortium \u2013 consisting of more than 2,000 scientists from 300 institutes in 13 European countries, the U.S., Canada, and Japan \u2013 is responsible for providing the scientific instruments and scientific data analysis. ESA selected Thales Alenia Space as prime contractor for the construction of the satellite and its service module, with Airbus Defence and Space chosen to develop the payload module, including the telescope. NASA provided the detectors of the Near-Infrared Spectrometer and Photometer, NISP. Euclid is a medium-class mission in ESA\u2019s Cosmic Vision Programme.<\/p>\n
