Scientists don't only try to find Earth-like planets with their sophisticated telescopes. They also look at the younger sun-like stars for more information. The logic says that since Earth is the only planet where life can sustain, if the scientists have to look for other planets to find surviving life forms, they will have to look in places that have conditions similar to our own. However, according to Lisa Kaltenegger, astronomer, a lot of opportunity is being lost.
Experts have located a new star with a record variation period of about 69 years.
