May 25 at 7:00 PM: Lecture by Ekaterina Efremova, "Jan Oort: From Comets to Galaxies"

🌠 Many people know that the Solar System contains the asteroid belt and the Kuiper belt. But not everyone has heard of the scattered disk and the Oort cloud. These regions are very extensive and occupy a significant portion of the Solar System. Furthermore, it is from there that icy visitors – comets – arrive.

In this lecture, we will discuss both the asteroid belt and the Oort cloud, as well as Jan Oort himself, after whom the cloud is named, how he was able to create a model of the Oort cloud, and why he studied the motion of stars in galaxies, and why an object consisting of a huge number of cometary nuclei bears his name.

👩‍🎓 Speaker: Ekaterina Efremova – astronomer, science popularizer, Moscow State Pedagogical University employee, co-organizer of the scientific travel club "ZonaZvezd."

The lecture is organized jointly with the S.P. Korolev Astrocomplex of the Institute of Physical and Theological Sciences of Moscow State Pedagogical University. A live broadcast will also be available on the channel of the Cultural and Educational Center "Arkhé":    / центрАрхэ
