But a speck
We are but a speck in our rather ordinary galaxy, just one of a billion galaxies in our part of the multiverse. Something to think about don't you think?
As part of an engineering test, NASA’s OSIRIS-REx spacecraft captured this image of the Earth and Moon using its NavCam1 imager on January 17 from a distance of 39.5 million miles (63.6 million km). When the camera acquired the image, the spacecraft was moving away from home at a speed of 19,000 miles per hour (8.5 kilometers per second).
We know so little but assume so much but we do know what the word assume means, right?
