The New Horizons spacecraft, having traveled nearly 3 billion miles, sends back its first close-up images of Pluto. The pictures reveal an alien landscape unlike anything scientists expected, dominated by a massive, heart-shaped feature on its surface. As the New Horizons Pluto mission continues, the spacecraft detects signals suggesting something bizarre is happening beneath the ice. NASA Scientists are baffled. Theories range from a massive impact to a cryovolcanic eruption of liquid nitrogen. Then, the mystery deepens. NASA officials observe strange shadows on Pluto moving across the surface, initially dismissed as a camera glitch but later confirmed to be real. Adding to the confusion, a Plutonian heat wave is detected, even though Pluto's atmosphere is mostly nitrogen and methane, gases that don't retain heat well. Could these be signs of an underground ocean or something even more extraordinary? Join the mission to uncover the truth behind these unexplained signals and the secrets of the outer solar system.
