DENVER (KDVR) — Colorado is no stranger to strange objects floating or flying across the sky (remember "Balloon Boy" from October 2009?), and many residents wanted answers for a strange balloon seen floating across the state on Tuesday.

The National Weather Service said it was a Stratollite balloon, owned by a private company in New Mexico that launches high-altitude balloons for research. The Moffat County Sheriff's Office also reported that residents had spotted the balloon just south of Craig.
