"Seven Billion Light Years"

"Seven billion light-years" is a measure of distance in space. A light-year is the distance light travels in one year, about 5.88 trillion miles (9.46 trillion kilometers). So, when astronomers say an object is seven billion light-years away, they mean that the light from that object has taken seven billion years to reach us. This also implies we observe that object as it was billions of years ago, offering a glimpse into the universe’s past. It reflects the vastness of space and the incredible distances between celestial objects.
