The Umov Effect—space dust clouds and the mysteries of the universe

FEFU scientists are developing a methodology to calculate the ratio of dust and gas in comas and tails of comets. This will reveal more about the history of the solar system and its development, as well as to understand the processes that took part on different stages of universal evolution.

A team of scientists from the Far Eastern Federal University (FEFU) under the supervision of the astrophysicist Evgenij Zubko, Ph.D., a lead scientist of the School of Natural Sciences at FEFU, is trying to solve a fundamental problem of modern astrophysics—to assess the reflectivity of cosmic dust particles and their ability to scatter star light. To do so, the scientists study the optic characteristics of dust particles in the comae and tails of comets.
