All stars shine brightly both day and night. However, during the daytime, the blue sky and brilliant sunlight overshadow these fragile beacons of stars. In the universe and on the Moon, where there is no atmosphere, stars can be seen clearly even near the Sun, as the sky there remains pitch black even in the daytime.
With a modern telescope, scientists can detect the light of stars even in the middle of the day. At certain times, it is even possible to see bright celestial bodies like Venus with the naked eye while the Sun is still up, provided that the sky is clear and observers know the exact direction to look.
Although Venus, along with Jupiter and Mars, are very bright planets that are typically only visible at dawn, it would be fascinating to find ways to observe them for as long as possible, even after sunrise. Dual-lens telescopes can extend this observation period.
