Getting closer to the”Big Bang”
Astronomers discover some of the oldest galaxies to date, a mere 787 million years after the “Big Bang.” But remember distance is time, so astronomers may only be seeing remnants of what once was. Much like the classic sci-fi movie Star Wars when Luke looks out at the two setting suns, more clues have been discovered about a binary system, thus indicating somewhere in the galaxy there might be a pair of stars with their own set of planets. Also Lunar Reconnaissance Orbiter gives us a glimpse of the Apollo 11 landing site – a remarkable image to see.
