The Hubble Space Telescope has helped scientists discover the farthest star known today. Icarus is located 9 billion light years from Earth. This is the first time that we have been able to establish a separate object in space at such a distance.
“For the first time, we see a separate star – not a supernova, not a gamma-ray burst, but one stable star – at a distance of 9 billion light-years, ” said Professor Alex Filippenko of the University of California. The star found is a hundred times farther away than the previous most distant star from our planet. Hubble took a picture back in 2016, but scientists have long been exploring images. Apparently, on the same site in 2011 the star was not:
To obtain an image of such a distant object, scientists succeeded with the help of the effect of a gravitational lens. This is the name of the phenomenon in which the cosmic body (planet, star, and so on) changes its direction of electromagnetic radiation by its gravitational field. The process is partly similar to how the most common lens refracts a light beam.
