What celestial body was referred to in a July 2015 article for sending a 'love note' back to Earth?

In July 2015, the celestial body that sent a 'love note' back to Earth was Pluto. This playful phrase was used to describe the data and images sent by NASA's New Horizons spacecraft after it conducted a flyby of Pluto. The spacecraft captured detailed images and information about Pluto's surface and atmosphere, revealing its heart-shaped glacier, which became affectionately referred to as "Tombaugh Regio." The message was symbolic of the deep interest and affection scientists and the public felt for this distant dwarf planet, particularly after being the last unexplored body in our solar system by a spacecraft. This historic event highlighted Pluto’s uniqueness and the emotional connection humanity has with exploring the universe. Other celestial bodies mentioned, like Mars and Venus, do not have a specific association with a 'love note' concept linked to that time frame, making Pluto the correct choice in this context.
