Most distant star ever spotted
The furthest individual star ever seen has been discovered in recent Hubble images, thanks to a naturally occurring gravitational quirk.
The light from the star, nicknamed Icarus, has taken nine billion years to reach us, and dates from when the Universe was four billion years old. The gravity of a galaxy cluster bent Icarus’s light, magnifying it by 2,000 times – a process known as gravitational lensing – making it visible.
“This is the first time we’re seeing a magnified, individual star,” says Patrick Kelly of the University of Minnesota, Twin Cities, who led the study. “You can see individual galaxies out there but this star is at least 100 times further away than the next individual star we can study, except for supernova explosions.” http://hubblesite.org
