After decades of drought, water levels in Lake Powell, the second-largest humanmade reservoir in the United States, have shrunk to its lowest level since it was created more than 50 years ago, threatening millions of people who rely on its water supply. Satellite images allow us to take a closer look at the dwindling water levels of the lake amidst the climate crisis.

Space Force is Releasing Decades of Tracking Data on a Thousand Bright Meteor Fireballs
When a meteoroid enters the Earth’s atmosphere at a very high speed it heats up. This heating up produces a streak of light and is termed a meteor. When a meteor is bright enough, about the brightness of Venus or brighter, it becomes a fireball. Sometimes these fireballs explode in the atmosphere, becoming bolides. These bolides are bright enough to be seen even during the day.
Is the origin of dark matter gravity itself?
Did the graviton, the quantum mechanical force carrier of gravity, flood the cosmos with dark matter before normal matter even had a chance to get started?

A SpaceX Dragon spacecraft docked at the International Space Station on Saturday with four private astronauts, beginning a planned stay of at least eight days — and maybe longer — while becoming the first mission with an all-commercial crew to visit the orbiting research complex.
Jupiter and Ganymede are Connected by Magnetic Fields
On July 5th, 2016, NASA’s Juno spacecraft arrived at Jupiter and began its four-year mission (which has since been extended to 2025) to study the gas giant’s atmosphere, composition, magnetosphere, and gravitational environment. Juno is the first dedicated mission to study Jupiter since the Galileo probe studied the system between 1995 and 2003. The images and data it has sent back to Earth have revealed much about Jupiter’s atmosphere, aurorae, polar storms, internal structure, and moons.
Ax-1, the first private crew to space station, welcomed aboard with astronaut pins
The three first-time fliers on the first commercial crew to visit the International Space Station arrived on board the orbiting outpost where they were pinned as the world's newest astronauts.

Astronauts are Practicing Landing at the Moon's South Pole
The European Space Agency (ESA) is learning how to touch down safely at the South Pole of the Moon, without ever leaving Earth. Actual Moon landings seem to be on the horizon in the next decade via the Artemis program, and astronauts are going to have to learn to handle the unique challenges of landing in the Moon’s polar environment. With low angle sunlight and deep, permanently shadowed craters, the Moon’s South Pole poses difficulties no Apollo mission ever faced. To get hands-on experience with this environment without risking human life, ESA is putting astronauts through their paces on high-tech simulators.
