Please could someone explain why Earth looks to bright when it is so far away? Also, why can't we see any other objects (other planets and stars) in the image?
Thank you.
Thank you.
MullaTheMech said:0.25^2 degrees(or is it 0.25 degrees^2)? Can you tell me about this unit in this context please. Is this used from a point of view like: the moon has a diameter of 0.5 degrees from a viewer on earth?
The "Pale Blue Dot" image is a photograph taken by NASA's Voyager 1 spacecraft on February 14, 1990. It shows Earth as a tiny, pale blue speck in the vastness of space from a distance of about 6 billion kilometers.
The "Pale Blue Dot" image is significant because it provides a unique perspective of Earth's place in the universe. It highlights the fragility and insignificance of our planet in the grand scheme of things, but also the interconnectedness of all living beings on Earth.
The "Pale Blue Dot" image was taken using a narrow-angle camera on Voyager 1. The spacecraft had already completed its primary mission to explore the outer planets of our solar system and was on its way out of the solar system when it turned its camera towards Earth.
Yes, if you look closely, you can see other planets in the "Pale Blue Dot" image. For example, the bright streak on the right side is actually Saturn, and the fainter dot above and to the left of Earth is Venus. However, Earth is the only planet that is clearly visible in the image.
The "Pale Blue Dot" image has had a profound impact on our perception of Earth. It has helped us realize the fragility and uniqueness of our planet, and the importance of protecting it. It has also sparked a sense of curiosity and wonder about the vastness of space and our place in it.
