The first images of the “Dark World” telescope were published
The European Space Agency’s Euclid Space Telescope is on its way to deciphering the mysteries of dark matter and dark energy in the universe.
This telescope sent its first images to Earth on Monday (July 31). While these portraits are mesmerizing, they also confirm that the space observatory’s instruments are working just fine.
Euclid’s success is really exciting because, simply put, the probe aims to map the dark half of our universe by analyzing billions of galaxies up to about 10 billion light-years away.
Better yet, the European Space Agency also says the ambitious map will be drawn in “3D” as it includes an element of time to show how these realms have evolved alongside the maturing cosmos.
Yannick Mellier, an astronomer at the Paris Institute of Astrophysics and the Euclid Consortium, said in a statement: “The first remarkable images obtained using the Euclid visible and near-infrared instrument open a new era for observational cosmology and statistical astronomy.” . They represent the beginning of the search for the nature of dark energy.

Euclid was launched from the Cape Canaveral Space Station in Florida on July 1.
The telescope, now about a million miles (1.6 million kilometers) from Earth, joined the James Webb Space Telescope on July 28 at what is known as the second Lagrange point. Over the next few months, scientists will continue to test the device until it officially begins development on its epic space probe. The images you see above were taken with an instrument on Euclid called VIS, which stands for “Visible Instrument”.

As its name suggests, the VIS records the universe through the part of the electromagnetic spectrum visible to the human eye, with wavelengths between 550 and 900 nanometers.
On the left, you can see the full field of view of the visible tool, and on the right, a zoomed-in version of it. The European Space Agency equates the area of the magnified image to about a quarter of the width and height of the full moon as seen from Earth.
Some of the most striking visual instrument images include cosmic rays shooting straight across the field, masses of unmistakable bright stars and, most importantly, a few fuzzy bubbles.
The European Space Agency explains that these bubbles are the galaxies that Euclid will examine as it makes a very detailed map of the universe, dark energy and all.
“Ground-based experiments don’t give you images of galaxies or star clusters, but here they are all in one field,” visible instrument scientist Reiko Nakajima said in a statement. Looking at them is beautiful and enjoyable.
Next, we come to NISP, the Euclid Near Infrared Spectrometer and Photometer. As the European Space Agency says, NISP has two roles. First, it can image galaxies in infrared light, or light invisible to the human eye that ranges from 950 to 2000 nm in the electromagnetic spectrum. The James Webb Space Telescope also uses such infrared wavelengths, which is why scientists often say it is unveiling an invisible universe.
Second, NISP can measure exactly how much light each galaxy emits, which can tell us how far away those galaxies are. The NISP images you see above are almost identical to the visible toolkit, with the left containing the full image while the right is a zoomed-in section.

The light from deep space also passes through several filters before reaching the NISP detector, and this provides very surprising results. These filters can do things like measure brightness at a specific infrared wavelength, which helps NISP’s galactic distance measurements.
Knud Jahnke, from the Max Planck Institute for Astronomy (MPIA) in Heidelberg, who works on the telescope, says: “Although these first test images are not yet usable for scientific purposes, I am happy that the telescope and its two instruments are now They work well in space.

In this image, which looks like a computer screensaver from the early 2000s, each streak represents a separate light spectrum from a galaxy or star.
Euclid has a device called grism that can split cosmic light into a full spectrum of wavelengths before sending the data to NISP.
With this process, scientists can determine, for example, how far away a particular galaxy is, as well as what the galaxy is chemically made of.
“We’ve seen simulated images, experimental images,” NISP instrument scientist William Gillard said in a statement. I still find it hard to believe that these images are from the real world. Very accurate and amazing.
What is Euclid’s next work?
Dark energy and dark matter pose some of the biggest and most fascinating questions in astronomy today.
None of these phenomena can be seen with the human eye, yet they seem to hold our universe together.
For starters, space is constantly expanding outward in every direction like an unburstable balloon. But the strange thing is that this expansion seems to be happening at a rate that scientists can’t explain by taking into account all the observable things in our universe.
Therefore, there must be something else accelerating cosmic expansion, which scientists call “dark energy.”
Meanwhile, in this expanding universe, there seems to be some kind of glue that makes sure the galaxies stay in place and determines how they are arranged. For example, scientists calculate that intergalactic gas and stars often move as if some kind of extra gravity is pulling them along. This is probably because some kind of invisible matter surrounds the galaxies in which these objects live, and therefore exerts gravitational forces on them. That invisible “glue” is known as dark matter.
Dark matter and dark energy are not necessarily made up of one or even two things. They can consist of a bunch of different components. Scientists just use these as expressions to describe gaps in our understanding of the universe.
The only thing we know for sure right now is that the dark universe exists.
But if Euclid’s mission to accurately map the universe is completed within the next six years or so, scientists may have some clues about what the dark universe is.
General Josef Aschbacher, director of the European Space Agency, said in a statement: “I have every confidence that the team behind this mission will succeed in asking Euclid to reveal a lot about the 95 percent of the universe that we currently know little about.”
