NASA shares pics of 'interstellar rose', 'heart in clouds' on Valentine's Day

NASA took to social media to share "nature's most romantic examples of pareidolia" on the occasion of Valentine's Day. Pictures shared by NASA showed a star cluster and its associated nebula resembling a rose and a heart-shaped feature centred above Pluto's equator. A picture also showed clouds with heart-like shapes in a pattern known as von Kármán vortices.
