    Light Sky
In summary, the conversation discusses a stationary light in the sky near the moon that is visible when there are no stars. The speaker is asking for help in identifying the light, but the other person states that more information is needed. The light is ultimately identified as Venus, and the speaker suggests using Stellarium to compare the location and time of the photo with the night sky.

I'm in Surrey, London, UK.

I've noticed this stationary light in the sky near the moon when there are no stars visible. What is it?

Thas picture is just a spot of light. Not even sure which spot you need. You're asking us to tell one spot from another.

You need much, much more information: as a start, where and when was this taken, where is the camera pointing, and what are the two objects shown?

Venus. It's Venus.

Nice photo!
I analyzed the photo very thoroughly. Judging from the light and the altitude my guess is that what you saw was this (I could not resist, sorry :smile: ).

Edit: On a serious note you could use the free software Stellarium and enter correct location and time and compare with what was visible at that time in the night sky.

1. What causes the light we see in the night sky?

The light we see in the night sky is primarily caused by stars. Stars are massive, luminous objects that emit light and heat through nuclear reactions in their cores. They are located at vast distances from Earth, but their light is so bright that it can be seen from our planet.

2. Are all the lights in the sky stars?

No, not all the lights in the sky are stars. Some lights may be planets, which are celestial bodies that do not emit light on their own but reflect the light of the sun. Other lights may be man-made objects such as satellites or aircraft with lights on them.

3. Why do some lights in the sky appear to move?

The lights in the sky that appear to move are typically planets or satellites. Planets, such as Mars or Jupiter, are constantly orbiting around the sun, so their position in the sky changes as the Earth rotates. Satellites, on the other hand, are objects that orbit around the Earth and can be seen as they reflect sunlight while passing overhead.

4. Can the lights in the sky ever change color?

Yes, the lights in the sky can change color. This can occur due to various reasons such as atmospheric conditions, the angle at which the light is reaching our eyes, or the distance from the light source. For example, the sun appears to be yellow or orange during sunrise and sunset because its light has to travel through more of Earth's atmosphere, which scatters the shorter blue wavelengths and leaves the longer red wavelengths to reach our eyes.

5. Can we see any other lights in the sky besides stars and planets?

Yes, there are other lights in the sky that can be seen, such as meteors, comets, and auroras. Meteors, also known as shooting stars, are small pieces of debris that enter Earth's atmosphere and burn up, creating a streak of light. Comets are also pieces of debris, but they have a distinctive tail of gas and dust that reflects sunlight. Auroras, or the Northern and Southern Lights, are colorful displays of light in the sky caused by charged particles from the sun interacting with Earth's magnetic field.
