Scientists say they have spotted a rare circle of light in space, which comes from a far-away galaxy which has never been observed before.<\/p>\n

The Euclid space telescope captured images of the light, known as an Einstein ring, created by gravitational lensing around a different galaxy which is closer to Earth – 500 million light years away – which scientists say is a “stone’s throw away in cosmic terms”.<\/p>\n

That closer galaxy – the foreground galaxy – is called NGC 6505. But the ring of light around its centre has never been detected before.<\/p>\n

The ring is made up of light from a background galaxy 4.42 billion light-years away and what can be seen from Earth is distorted by gravity.<\/p>\n

The distant galaxy itself has not been observed before and has not yet been named.<\/p>\n

Such rings can help scientists test Albert Einstein’s general theory of relativity, according to Professor Thomas Collett, from the University of Portsmouth’s Institute of Cosmology and Gravitation.<\/p>\n

“This lens is particularly special because it’s in our cosmic backyard: a ‘mere’ 500 million light-years away,” he said.<\/p>\n

“In fact, it’s so close that astronomers first observed the [NGC 6505] galaxy in the 1880s, but only with the resolving power of Euclid can we now reveal that it’s a gravitational lens.<\/p>\n

“Nearby lenses are exciting because they allow us to test the validity of general relativity on astronomical scales.”<\/p>\n

What is Einstein’s theory of general relativity?<\/strong><\/p>\n

Einstein’s theory of general relativity predicts light will bend around objects in space, so they focus the light like a giant lens – and the effect would be bigger for massive galaxies.<\/p>\n

It allows astronomers to see light from distant galaxies that would otherwise remain hidden.<\/p>\n

‘This one is particularly special’<\/strong><\/p>\n

Conor O’Riordan of the Max Planck Institute for Astrophysics in Germany and lead author of the first scientific paper analysing the ring, said: “An Einstein ring is an example of strong gravitational lensing.<\/p>\n

“All strong lenses are special, because they’re so rare, and they’re incredibly useful scientifically.<\/p>\n

“This one is particularly special, because it’s so close to Earth and the alignment makes it very beautiful.”<\/p>\n

The Euclid mission was launched in July 2023 and aims to create a 3D map of the universe by observing two billion galaxies. It will help scientists unravel the cosmic history of the universe.<\/p>\n<\/p><\/div>\n
