![NASA's Mars Global Surveyor spacecraft has captured a lovely view of a bright, heart-shaped mesa in the south polar region of the red planet. The heart-shaped feature is about 837 feet across. According to Mars Global Surveyor scientists, the presence of this mesa indicates that the darker, rough terrain that surrounds it was once covered by a layer of the bright material.](https://api.time.com/wp-content/uploads/2016/02/time-valentines-day-hearts-in-space-mars-red-planet.jpg?quality=75&w=2400)
![Colliding galaxies make love, not war This Hubble image taken in Aug. 2012, of the Antennae galaxies is the sharpest yet of this merging pair of galaxies. As the two galaxies smash together, billions of stars are born, mostly in groups and clusters of stars. The brightest and most compact of these are called super star clusters.](https://api.time.com/wp-content/uploads/2016/02/time-valentines-day-hearts-in-space-hubble-galaxy.jpg?quality=75&w=2400)

Julien Girard drew the heart in the air by shining a tiny flashlight keychain at the camera during a 25-second exposure with a tripod. The central region of the Milky Way appears in the middle of the heart, as the plane of our galaxy stretches across the image.](https://api.time.com/wp-content/uploads/2016/02/time-valentines-day-hearts-from-space-eso.jpg?quality=75&w=2400)
