New Space Telescope Euclid Beams Back First Razor-Sharp Images

Here’s lookin at you, ’clid.

On Tuesday, the European Space Agency revealed the first images captured by Euclid, a brand-new space telescope on a mission to study dark matter and energy.

The telescope sports much more sensitive sensors than its predecessors, which it uses to capture images across an extremely wide field of view.

The VISible instrument, one of the two instruments aboard, uses an array of 36 detectors to capture the equivalent of nearly 70 4k resolution screens in one capture. The resulting image covers a portion of the night sky equivalent to the area of two-and-a-half full moons seen from Earth.

The VISible instrument collects images in the visible spectrum of light, while the second instrument, a Near-Infrared Spectrometer and Photometer, measures near-infrared light. 

Over the next six years, Euclid will use both instruments to assemble a massive cosmic 3D map. Scientists will use that data to tease out a better understanding of how dark matter shapes and influences the universe.

“Dark matter pulls galaxies together and causes them to spin more rapidly than visible matter alone can account for; dark energy is driving the accelerated expansion of the Universe,” explained European Space Agency director of science Carole Mundell in a release.

“Euclid will for the first time allow cosmologists to study these competing dark mysteries together,” she continued.

Here are some of the images, with descriptions from the European Space Agency: 

The Perseus Cluster Of Galaxies

“This incredible snapshot from Euclid is a revolution for astronomy,” the ESA writes. “The image shows 1,000 galaxies belonging to the Perseus Cluster, and more than 100,000 additional galaxies further away in the background. Many of these faint galaxies were previously unseen. Some of them are so distant that their light has taken 10 billion years to reach us. By mapping the distribution and shapes of these galaxies, cosmologists will be able to find out more about how dark matter shaped the Universe that we see today.”

Spiral Galaxy IC 342, AKA The “Hidden Galaxy”

“Over its lifetime, our dark Universe detective will image billions of galaxies, revealing the unseen influence that dark matter and dark energy have on them,” the ESA writes of this image. “That’s why it’s fitting that one of the first galaxies that Euclid observed is nicknamed the ‘Hidden Galaxy’, also known as IC 342 or Caldwell 5. Thanks to its infrared view, Euclid has already uncovered crucial information about the stars in this galaxy, which is a look-alike of our Milky Way.”

Irregular Galaxy NGC 6822

“To create a 3D map of the Universe, Euclid will observe the light from galaxies out to 10 billion light-years,” the ESA writes. “Most galaxies in the early Universe don’t look like the quintessential neat spiral, but are irregular and small. They are the building blocks for bigger galaxies like our own, and we can still find some of these galaxies relatively close to us. This first irregular dwarf galaxy that Euclid observed is called NGC 6822 and is located close by, just 1.6 million light-years from Earth.”

The Horsehead Nebula

“In Euclid’s new observation of this stellar nursery, scientists hope to find many dim and previously unseen Jupiter-mass planets in their celestial infancy, as well as young brown dwarfs and baby stars,” the ESA writes.

Globular Cluster NGC 6397

“This is the second-closest globular cluster to Earth, located about 7800 light-years away,” the ESA writes of the above image. “Globular clusters are collections of hundreds of thousands of stars held together by gravity. Currently no other telescope than Euclid can observe an entire globular cluster in one single observation, and at the same time distinguish so many stars in the cluster.”
