A cloud that resembled something out of this world was spotted throughout much of the Denver metro on Tuesday morning.

Several 9NEWS viewers shared photos of a pink-hued cloud visible during the morning commute that looked somewhat like an alien spacecraft.

Meteorologist Belen De Leon says the mysterious looking formations are called lenticular clouds – lens shaped clouds that form on the downwind side of a mountain or range.

They’re created when moist, stable air flows over a mountain.

Cloud condensation occurs at the crest of the wave and then dissipates as the air rides back down the other side of the wave.

The lenticular clouds were spotted around Wheat Ridge, Brighton, Broomfield, Boulder and Lafayette.

Meteorologist Cory Reppenhagen shot a mesmerizing time-lapse showing how the cloud appears to hover in one spot.
