How close will Jupiter, Saturn come today in 400 yrs & how can people watch it?
On Monday night, Jupiter and Saturn will be at their closest separation in the sky since 1623 at 0.1° apart. "To see the Great Conjunction, look toward the southwest after sunset: it doesn't matter where on Earth you are!" tweeted astronomer Dr James O'Donoghue. "Find a spot with...unobstructed view of the sky, such as a field or park," said NASA.
