Hubble finds most distant star
In the galaxy cluster MACS J1149 Hubble has spotted the most distant star ever seen.
The star existed when the Universe was only 30 percent of its current age!
It became visible by gravitational lensing. The cluster and an object in the cluster acted as natural lenses amplifying the light of the star behind.
The light of the star was magnified by 2000 times!
The star is extremely luminous, blue in colour, and twice as hot as our Sun.
Using gravitational lenses we can study the evolution of the earliest stars in the Universe.
