In a delightful twist to planetary science, NASA's Mars Reconnaissance Orbiter has captured images of dozens of heart-shaped landforms sprinkled across the Martian surface—turning the cold, red expanse into a gallery of cosmic affection.
These curious shapes have appeared in various regions, from Arabia Terra to the southern highlands. While they might evoke sentiments of love and whimsy, scientists assure us they’re no extraterrestrial Valentine’s messages. Instead, they’re crafted by natural forces over millions of years.
How Does Mars Carve Out a Heart?
- Impact Craters: Small meteoroids collide with Mars, revealing lighter sediment underneath and sculpting crater patterns that coincidentally resemble hearts.
- Erosion & Volcanism: Mesas and depressions, shaped by erosion or volcanic activity, also contribute to heart-like silhouettes.
- Lighting & Shadows: Martian sunlight plays visual tricks—enhancing ridges and dips to accentuate these romantic outlines.

Mars: The Solar System’s Secret Romantic?
NASA has been sharing these striking visuals each year around Valentine’s Day, fueling public fascination. One post even quipped, “Looks like Mars has been secretly playing Cupid all along.”The trend has gained momentum online, with space enthusiasts tagging their favorite heart-shaped formations and debating whether the Red Planet deserves a new nickname: ‘The Loveliest Planet.’
What It Means for Science & Storytelling
While the formations are scientifically valuable—helping researchers analyze erosion patterns, geological layering, and ancient water flows—they also serve a purpose beyond data. They invite the public to engage with space exploration in a playful, emotional way.After all, when a distant planet 225 million kilometers away starts resembling symbols of love, it’s hard not to feel a cosmic connection.
