"A mosaic of images from the European Space Agency’s Euclid space telescope
captures more than 14 million galaxies, offering a first glimpse of a “cosmic
atlas”. The mapping project could add to our understanding of the role dark
matter and dark energy play in the structure of the universe.
“The scale is utterly incomprehensible,” Carole Mundell, the director of
science at the ESA, said at a meeting of the International Astronautical
Congress in Italy on 15 October. Representing the image at full resolution
would require more than 16,000 4K TV screens, she said.
The mosaic of 260 images is the first glimpse into Euclid’s project to create
the largest and most accurate map of the universe yet. The vast number of
galaxies was captured during a two-week survey in April and represents only 1
per cent of the final map. The image covers an area of the southern sky about
500 times the size of the full moon.
The wispy blue band across the image is dust and gas in the nearby Milky Way,
known as “galactic cirrus”, said Mundell. Zooming in reveals swirling galaxies
interacting hundreds of millions of light years away, some with a supermassive
black hole at their centre that can produce gravitational waves measurable on
Earth.
Over the next six years, the telescope will autonomously scan about a third of
the night sky. The researchers anticipate the final map will show around 8
billion galaxies, each with billions of stars, stretching across 10 billion
years of cosmic history."
