Absence makes the heart grow fonder ❤️⁣ ⁣ Our New Horizons spacecraft captured this heart-shaped glacier. It lies on Pluto’s surface, which also that features mountains, cliffs, valleys, craters, and plains, thought to be made of methane and nitrogen ice. ⁣ ⁣ Pluto lies in the Kuiper belt, a donut-shaped region of icy bodies remnants from the early days of our solar system, beyond the orbit of Neptune. The small icy world is on average around 3.7 billion miles (5.9 billion kilometers) away from the Sun, but its oval shaped orbit can bring Pluto closer to than Neptune at its closest point, expanding the tenuous atmosphere as it gets closer to our Sun.⁣ ⁣ Image description: Pluto’s surface is marked with cracks and craters in shades of brown. The partially visible heart appears in the lower right of the small world, which is surrounded by black space.⁣ ⁣ Credit: NASA/Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute⁣ ⁣ #Pluto #SolarSystem #Astronomy #NewHor...
