Thanks to 3 wide-angle cameras, the Hubble Space Telescope is able to capture the so-called “penta-vision” effect, caused by gravitational lenses. Astronomers from the European Space Agency (ESA) They posted An image taken by the ship illustrates the phenomenon.
Six points of light converge in the center of this image, four of which form a circle around the central pair. However, as the researchers explain, “appearances can be deceiving.” “This formation does not consist of six individual galaxies, But only for three: to be precise, a pair of distant galaxies and quasars,” they detail from the European Space Agency.
This rare phenomenon is caused by the two galaxies in the foreground acting as lenses.
The astronomers explained that “the central pair of galaxies in this image are actually two separate galaxies, located 3.8 billion light-years from Earth.” “The four bright spots surrounding them, the darkest in the center, are— Actually five separate images of one quasar, known as 2M1310-1714, is a very bright but distant object. “
According to the European Space Agency, the reason behind the “pentagram vision” effect is a phenomenon known as gravitational lensing.
“Gravity lensing occurs when a celestial body with a very large mass distorts the fabric of space in such a way that light, traveling through that space from a distant object, bends and increases in size so that humans on Earth can observe some magnified images. from distant sources,” the scientists explain in detail.
