Comet C/2023 A3 (Tsuchinshan-ATLAS) over Austria
Astrophotographer Michael Karrer: "The comet in early twilight. Cirrus clouds gave a nice touch, even if we had to worry about them hiding the comet at some time."
Austria, formally the Republic of Austria, is a landlocked country in Central Europe, lying in the Eastern Alps. Austria is bordered by Germany to the northwest, the Czech Republic to the north, Slovakia to the northeast, Hungary to the east, Slovenia and Italy to the south, and Switzerland and Liechtenstein to the west.
The Oort cloud is theorized to be a vast cloud of icy planetesimals surrounding the Sun at distances ranging from 2,000 to 200,000 AU (0.03 to 3.2 light-years). The concept of such a cloud was proposed in 1950 by the Dutch astronomer Jan Oort, in whose honor the idea was named. Oort proposed that the bodies in this cloud replenish and keep constant the number of long-period comets entering the inner Solar System—where they are eventually consumed and destroyed during close approaches to the Sun.
