Yes, it is possible to see Earth from space. Astronauts aboard the International Space Station (ISS) and other spacecraft have the opportunity to observe Earth from a unique vantage point. They can witness the beautiful view of our planet, with its continents, oceans, and weather patterns.
When viewing Earth from space, the light from other stars does not significantly affect what astronauts see. The Earth's atmosphere acts as a filter, scattering and absorbing much of the starlight before it reaches the observer. Additionally, the brightness of stars is much lower compared to the Sun, so their impact on the overall view of Earth is minimal.
However, it's worth noting that the presence of the Sun can greatly impact the visibility of stars and other celestial objects. The Sun is an extremely bright source of light, and its illumination can make it difficult to observe fainter stars or objects in the same field of view. This phenomenon is known as "daylight" or "Earthshine" and is one of the reasons why stars are typically not visible during daytime on Earth or from space.
Overall, while astronauts can see Earth from space, the light from other stars has little effect on their observations due to the filtering properties of the Earth's atmosphere and the brightness of distant stars.
