'Farout' is the farthest Solar System object known to date
The reach of the Solar System extends well beyond the full-size planets, and that's becoming clearer than ever with a new discovery. Astronomers have detected 2018 VG18 "Farout," which is the most distant Solar System object known to date at 120AU from the Sun (about 11.15 billion miles) -- the previous record-setter, the dwarf planet Eris, is 'just' 96AU away. That makes it over three and a half times farther from the Sun than Pluto (34AU), and over 100 times farther than Earth. But what is it, exactly?
World's largest telescope underway, scientists definitely observe big bang
Once again astronomers are observing formative explosions, but this time a little bit closer to home. Three million cubic feet of planet earth is being blasted from the Chilean Andes as work on what will be the world's largest telescope begins. The location is the Carnegie Institution's Las Campanas Observatory, and the project is a collaboration between South Korean, Australian and American institutions to create the Giant Magellan Telescope. The first mirror segment is just being completed, and is so precise, it matches its optical prescription to within a millionth of an inch. The project will cost $700 million once complete, small change we say for a chance to glimpse light from the edge of the Universe.
