As Papá fell sound asleep, Catalina slid from her bed and felt her way to the front door. The girl waited a moment to see if any of her family would wake, but nobody stirred. She tiptoed upstairs to her “Observatory”， longing for drinking in deep lungfuls of the clear night air under the bright stars.
She polished her dear telescope, which was presented by her grandpa, the only one to support her dream. She assembled (组装) it, disassembled it and reassembled it repeatedly, knowing its parts very well.
Through it she could explore the unknown galaxy, the Milky Way stretching across the deep blue sky. Night was always her favorite time. When everything was quiet, she was lost in her starry night. At this moment, she seemed to forget her cares and sorrows in the daytime.
She told her secret dream to these beloved ones, her friends, teachers and even her father. When she said, “Papá， I want to be an astronomer working in the Cerro Tololo Inter-American Observatory someday，” her father replied, “Maybe if you work hard, you'll be hired to clean the offices.” No one believed she would be a scientist one day. But why She knew she could be a good scientist. She knew it!
A big day was coming—to visit the Cerro Tololo Inter-American Observatory, where she had visited for dozens of times, familiar with every set of the instruments there. This time with her classmates she was still eager for something stimulating.
She took a cautious step forward, holding her breath, and her eyes getting closer to the lens ( 镜片) of the
telescope. She adjusted the device softly and carefully, hoping to find more... “Bang！...” suddenly there came a loud noise. One of her old friends “one-meter” telescope fell down, broken.
