Đề bài

Read the following passage about SATELLITES AND SPACE OBSERVATION and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 23 to 30.

A NASA study warns about a serious problem facing astronomy today. Thousands of satellites are now in Earth's orbit, and this number will grow to hundreds of thousands soon. These satellites reflect sunlight and emit heat into space. This causes light pollution that damages images taken by space telescopes. Scientists are worried about how this will affect our ability to study the universe and explore distant objects in space.

The problem affects many important telescopes. The Hubble Space Telescope may have 40% of its images affected by satellite interference. Newer telescopes like SPHEREx and ARRAKIHS could have problems with up to 96% of their observations. This is a serious issue because these telescopes help scientists make important discoveries. When satellite trails appear in telescope images, it becomes much harder to see faint stars and galaxies clearly.

Researchers cannot easily find distant galaxies, planets around other stars, or dangerous asteroids near Earth because of this satellite pollution. The contamination from these objects creates major problems for astronomical research. Scientists waste time and money trying to clean data or repeat observations. This situation threatens the future of space-based astronomy and our ability to make new discoveries about our universe and space.

Scientists suggest several solutions to fix this problem. Satellites should be placed in lower orbits or better locations. They should be designed to reflect less light. Computer programs can help remove satellite marks from images. Most importantly, countries need international rules for using Earth's orbit. This shared space should not be used for unlimited commercial purposes. Working together is essential to protect astronomy's future.
