Professor Boris Shustov, the director of the Institute of Astronomy, visited Ural Federal University to meet with students and deliver a lecture on space and potential threats to earth.
Shustov said the biggest threat in space is human involvement in it. The accumuation of space debris during human space exploration is becoming a hazard, according to the professor.
He also spoke on the topic of the Chelyabinsk meteorite, the first fragments of which were discovered by an expedition from the Ural Federal University, as well as the full range of actions employed in detecting asteroid-comet hazards. He said the study of such hazards requires international cooperation from scientists of various disciplines.
Shustov spoke with students during the visit, including Igor Helmets, who expressed excitement to discover that such a "high level specialist" would be visiting to "lecture on the stars far from us and about what is happening outside the earth's solar system."
