Happy hours are not observed; pocket watch with a heart-shaped chain
The red-haired cat looks in surprise towards the observer
The scale of one planet and the observable universe
A pigeon observes the beauty of the city from a height
We observe the nature of English fields planted with lavender
A dilapidated observation tower near an abandoned country road
It is interesting to observe the planet through a telescope
The shining horizon is observed from the city embankment
The stellar atmosphere is the region in which the directly observed radiation is formed[33]
