School students around the world are invited to take part in the 2016 Catch a Star astronomy writing contest.
Catch a Star is organised jointly by the European Association for Astronomy Education (EAAE) and ESO. Its aim is to encourage creativity and independent work amongst students, and to strengthen and expand their astronomical knowledge and skills.
To participate, students should submit a written report on an astronomical topic of their choice — for example, an astronomical object, phenomenon, observation, scientific problem or theory. Reports must be written in English and be no more than 5000 words in length. They may be undertaken by groups of up to three students, plus a group leader who is not a student.
