Does Venus glow at night?
Excuse me, but could you clarify your question? Are you asking if the planet Venus, which is the second planet from the Sun, emits a visible glow at night from Earth's perspective? If so, it's worth noting that Venus is indeed visible in the night sky, and it is often referred to as the "evening star" or "morning star" depending on when it appears. Venus is one of the brightest objects in the night sky, and it has a distinct golden or whitish hue that can appear to glow. However, it does not emit light of its own, but rather reflects sunlight back to us. So, in a sense, Venus does "glow" at night, but it's important to understand that this is due to reflected light, not light generated by Venus itself.

Do old radium watches still glow?
The question that often arises among collectors and enthusiasts alike is: "Do old radium watches still glow?" This curiosity stems from the historical use of radium in watch dials during the early 20th century. Radium was prized for its ability to emit a faint glow in the dark, often referred to as "luminosity." However, over time, the radioactive decay of radium leads to a decrease in its ability to emit light. Therefore, the glow of old radium watches has significantly diminished, if not completely disappeared. While some may still exhibit a faint glow under specific conditions, it is generally accepted that the majority of radium watches no longer retain their original luminosity. This is due to the natural decay process of radium and the passage of time.
