Juno.

https://www.youtube.com/watch?v=XpsQimYhNkA

NASA’s Juno spacecraft captured a unique time-lapse movie of the Galilean satellites in motion about Jupiter. The movie begins on June 12th with Juno 10 million miles from Jupiter, and ends on June 29th, 3 million miles distant. The innermost moon is volcanic Io; next in line is the ice-crusted ocean world Europa, followed by massive Ganymede, and finally, heavily cratered Callisto. Galileo observed these moons to change position with respect to Jupiter over the course of a few nights. From this observation he realized that the moons were orbiting mighty Jupiter, a truth that forever changed humanity’s understanding of our place in the cosmos. Earth was not the center of the Universe. For the first time in history, we look upon these moons as they orbit Jupiter and share in Galileo’s revelation. This is the motion of nature’s harmony.

Why no aquarium has a great white shark – usually

https://www.youtube.com/watch?v=QMbHLF_zwjs

There are several aquariums around the world, including one in Georgia, that house whale sharks, the biggest fish in the sea. But not one has a great white shark on display. Aquariums have made dozens of attempts since the 1970s to display a captive great white shark. Most of those attempts ended with dead sharks. By the 2000s, the only group still trying was the Monterey Bay Aquarium, which spent a decade planning its white shark program. In 2004, it acquired a shark that became the first great white to survive in captivity for more than 16 days. In fact, it was on display for more than six months before it was released back into the ocean. In the following years, the Monterey Bay Aquarium hosted five more juvenile white sharks for temporary stays before ending the program in 2011. It was an expensive effort and had come under criticism due to injuries that some of the sharks developed in the tank. Responding to those critics, Jon Hoech, the aquarium’s director of husbandry operations, said: “We believe strongly that putting people face to face with live animals like this is very significant in inspiring ocean conservation and connecting people to the ocean environment. We feel like white sharks face a significant threats out in the wild and our ability to bring awareness to that is significant in terms of encouraging people to become ocean stewards.” Check out the video above to learn why white sharks are so difficult to keep in captivity and how the Monterey Bay Aquarium designed a program that could keep them alive.

The April 2015 Nepal earthquake (Nepali: विसं २०७२ को महाभूकम्प) (also known as the Gorkha earthquake) killed over 8,000 people and injured more than 21,000. It occurred at 11:56 Nepal Standard Time on 25 April, with a magnitude of 7.8Mw or 8.1Ms and a maximum Mercalli Intensity of IX (Violent). Its epicenter was east of Gorkha District at Barpak, Gorkha, and its hypocenter was at a depth of approximately 8.2 km (5.1 mi). It was the worst natural disaster to strike Nepal since the 1934 Nepal–Bihar earthquake.

The earthquake triggered an avalanche on Mount Everest, killing 21, making April 25, 2015 the deadliest day on the mountain in history. The earthquake triggered another huge avalanche in the Langtang valley, where 250 people were reported missing.

Shock Breakout: Exploding Star

https://www.youtube.com/watch?v=kLlILnQjGfc

The brilliant flash of an exploding star’s shockwave—what astronomers call the “shock breakout” — is illustrated in this cartoon animation. The animation begins with a view of a red supergiant star that is 500 times bigger and 20,000 brighter than our sun. When the star’s internal furnace can no longer sustain nuclear fusion its core to collapses under gravity. A shockwave from the implosion rushes upward through the star’s
