Rare planetary alignment visible tonight.

Five planets, including Mars, Uranus, Venus, Mercury, and Jupiter, will align under the moon in the western sky shortly after sunset on Tuesday evening. Jupiter and Mercury will disappear under the horizon after 7:45 p.m., but the other three planets may still be visible. Viewing conditions will be best in central and southern New Hampshire, where clouds will break apart, but it may be challenging to see up north due to lingering clouds and flurries.
