American space agency Nasa has agreed to rethink its decision to abandon the Hubble telescope.
The decision was made earlier this month but, after people wrote to Nasa asking to keep the telescope going, a review is now underway.
Nasa was worried about sending shuttles to the telescope following last year's Columbia disaster. Without help, Hubble would stop working in a few years.
Hubble has sent amazing images back to earth since it was launched in 1990.
