One of Euclid’s primary goals is to observe dark matter and dark energy. While dark matter has never been detected, it is believed to make up 85% of the total matter in the universe. Meanwhile, dark energy is a mysterious force thought to play a role in the accelerating expansion of the universe. Rhodes is the US science lead for Euclid and principal investigator for NASA’s Euclid dark energy science team. “The images capture detail from clusters of stars near an individual galaxy to some of the largest structures in the universe.

Ninety percent of the mass in this cluster is dark matter. Gravity makes dark matter clump together, but dark energy counteracts this effect. Studying the density of dark matter across the cosmos will help astronomers learn how dark energy influences the structure of our universe. The telescope’s sensors make it like a net for light, Dr. Cuillandre said. “It’s very rare to find an isolated galaxy,” Dr. Cuillandre said.

What Euclid’s first images revealEuclid focused on an array of targets for its first scientific images. While dark matter has never actually been detected, it is believed to make up 85% of the total matter in the universe. Both dark matter and dark energy also play a role in the distribution and movement of objects, such as galaxies and stars, across the cosmos. These observations will effectively allow Euclid to see how the universe has evolved over the past 10 billion years. “Euclid will make a leap in our understanding of the cosmos as a whole, and these exquisite Euclid images show that the mission is ready to help answer one of the greatest mysteries of modern physics,” said Carole Mundell, ESA Director of Science, in a statement.

☆ Euclid Telescope Dazzles With Detailed First Images of Our Universe

“And it’s those ingredients pulled together that is going to make Euclid the iconic cosmology mission of the day.”Whereas NASA’s James Webb Space Telescope zooms in on one part of the sky at a time, Euclid excels at imaging wide, but still detailed, swaths of the universe. That’s perfect for “when you want to look for a needle in a haystack,” Dr. Seiffert said, including objects like free-floating worlds. With the data Euclid sends home, researchers can learn about how the web of dark matter cementing our universe together influences the shapes and motions of visible objects in space. The telescope’s detailed resolution is also expected to help scientists map the distribution of galaxies across cosmic time, aiding in understanding dark energy, the inexplicable force pulling the universe apart. Over the summer, scientists worked around the clock to fix a faulty navigation sensor that made Euclid create images of winding star trails as the telescope tried to capture a piece of sky.

CAPE CANAVERAL, Fla. (AP) — Scientists on Tuesday unveiled the first pictures taken by the European space telescope Euclid, a shimmering and stunning collection of galaxies too numerous to count. The photos were revealed by the European Space Agency, four months after the telescope launched from Cape Canaveral. Although these celestial landscapes have been observed before by the Hubble Space Telescope and others, Euclid's snapshots provide "razor-sharp astronomical images across such a large patch of the sky, and looking so far into the distant universe," the agency said. In one picture, Euclid captured a group shot of 1,000 galaxies in a cluster 240 million light-years away, against a backdrop of more than 100,000 galaxies billions of light-years away. Although the Hubble Space Telescope previously observed the heart of this galaxy, Euclid’s shot reveals star formation across the entire region, scientists said.

☆ Euclid telescope shares its first glimpses of the universe

CNN —The Euclid space telescope, designed to investigate some of the universe’s biggest mysteries, has captured its first glimpses of the cosmos. Investigating invisible dark matterEuclid’s primary goal is to observe the cosmic mysteries of the universe, including dark matter and dark energy. While dark matter has never actually been detected, it is believed to make up at least 85% of the total matter in the universe. These observations will effectively allow Euclid to see how the universe has evolved over the past 10 billion years. As Euclid makes its observations, the telescope will create a catalog of about 1.5 billion galaxies and the stars within them.

☆ A.I. Is Coming for Mathematics, Too

For more than 2,000 years, Euclid’s text was the paradigm of mathematical argumentation and reasoning. “Euclid famously starts with ‘definitions’ that are almost poetic,” Jeremy Avigad, a logician at Carnegie Mellon University, said in an email. But by the 20th century, mathematicians were no longer willing to ground mathematics in this intuitive geometric foundation. Eventually, this formalization allowed mathematics to be translated into computer code. In 2019, Christian Szegedy, a computer scientist formerly at Google and now at a start-up in the Bay Area, predicted that a computer system would match or exceed the problem-solving ability of the best human mathematicians within a decade.

☆ The Dark Universe Is Waiting. What Will the Euclid Telescope Reveal?

At 11:12 a.m. on Saturday, the Euclid spacecraft launched into space on its mission to chart the history of our universe as far back as 10 billion years ago. Researchers plan to use Euclid’s map to explore how dark matter and dark energy — mysterious stuff that makes up 95 percent of our universe — have influenced what we see when we look out across space and time. “Euclid is coming at a really interesting time in the history of cosmology,” said Jason Rhodes, a physicist at NASA’s Jet Propulsion Laboratory who leads Euclid’s U.S. science team. “We are entering a time when Euclid is going to be great at answering questions that are just now emerging. And I am certain that Euclid is going to be fantastic for answering questions we haven’t even thought of.”

The European Space Agency’s Euclid space telescope launched at 11:12 a.m. The Euclid space telescope is seen right before its installation in the nose of the SpaceX Falcon 9 rocket on Tuesday. Investigating cosmic mysteriesEuclid’s primary goal is to observe the “dark side” of the universe, including dark matter and dark energy. While dark matter has never actually been detected, it is believed to make up 85% of the total matter in the universe. Both dark matter and dark energy also play a role in the distribution and movement of objects, such as galaxies and stars, across the cosmos.
