The European Space Agency has released the first data from its Euclid Space Telescope, hoping to understand the mystery of dark energy and dark matter.
The first transistor shows three pieces of the sky, each of which represents a set of galaxies. Part of the sky shows more than 300 times the size of the moon when seen from the Earth.
Finally, Euclid hopes to mapping a complete atlas of the world and scanning more than a third of the sky.
Euclid, launched in 2023 on a planned six -year mission, is an observatory collecting data on how the world is expanded and how its structure is formed over time and interesting information on the nature of dark energy and dark matter and the role of large scales.
The polls revealed on Wednesday constitute only about half of the ultimate goal of the mission. This data shows only a week of observations, including one scanning from all three areas, but covers 26 million galaxies to 10.5 billion light -years. One light year, the distance from the distance in one year, is 5.9 trillion miles (9.5 trillion kilometers).
The Big Bang event began about 13.8 billion years ago, which has been expanding since then.
The contents of the world include ordinary matter as well as dark matter and dark energy. Ordinary matter – stars, planets, gas, dust and all familiar things on Earth – maybe 5 % of the material. Dark matter is an invisible substance that may make up about 27 % of the cosmos. Dark energy, a vague component that is thought to be responsible for the expansion of the world’s acceleration, may account for 68 %.
Images of the newly released Euclids to the large -scale galaxies in what is known as the cosmic web is essentially the backbone of the world. On this web, there are galaxies concentrations with space cavities, as if the galaxies were sitting on wide empty bubbles.
According to the researchers, the cosmic web structure offers clues to dark matter and dark energy.
Carroll Mondel, the European Space Agency’s director of science, called Okhalid “Dark Detective”.
“We now understand about 5 % of the world,” Mandeel said. “The other 95 % is dark and unknown.”
Euclid measures different forms and distribution of galaxies with high resolution imaging tools, or VIS, while its infrared or NISP tool determines the distances and masses of the galaxy. Euclid is eventually expected to get more than 1.5 billion galaxies.
“It is investigating the farther objects in the world with a greater amount of sky that has been explored for objects from any poll before,” said Chris Duffy of the University of Lancaster in the UK, a scientist involved in the study.
The Duffy section of Euclid’s research focuses on transient objects – things that appear only briefly – such as star explosions called Supernovae in observations.
The first joint catalog of more than 380,000 galaxies with different shapes and sizes was classified on Wednesday with features such as spiral arms and central bars, as well as attributes that indicate galactic integration.
“This will be the first piece of the biggest catalog of the galaxies,” said Mike Walmolidi, an Euclid scientist.
Light travel to the ground is bent from remote galaxies and is distorted by ordinary and dark matter in the foreground in a manifestation called gravitational lens. This is one of the tools used by Euclid to read how to distribute dark matter. Researchers are being discovered to identify strong gravitational lenses through Euclid data and have identified about 500 candidates.
“The invisible dark matter in the huge space of galaxies, bending light beams like a magnification glass. It distort and measure the galaxies behind them to arches and rings, and measuring distortion allows us to measure the invisible dark matter. But the galaxies must be very strong.”
“Euclid is the best tool ever made to find these, because it can get an incredibly sharp image of the wide pieces of the sky,” he said.
The next version of Euclids data, planned for October 2026, covers an area 30 times larger than Wednesday’s release.
