Saturn's Northern Hexagon
Image Credit: NASA, ESA, JPL, SSI, Cassini Imaging Team
Explanation: Why would clouds form a hexagon on Saturn? Nobody is sure. Originally discovered during the Voyager flybys of Saturn in the 1980s, nobody has ever seen anything like it anywhere else in the Solar System. Acquiring its first sunlit views of far northern Saturn in late 2012, the Cassini spacecraft's wide-angle camera recorded this stunning, false-color image of the ringed planet's north pole. The composite of near-infrared image data results in red hues for low clouds and green for high ones, giving the Saturnian cloudscape a vivid appearance. This and similar images show the stability of the hexagon even 20+ years after Voyager. Movies of Saturn's North Pole show the cloud structure maintaining its hexagonal structure while rotating. Unlike individual clouds appearing like a hexagon on Earth, the Saturn cloud pattern appears to have six well defined sides of nearly equal length.

This animation shows a purple burst of gas gurgling in front of a background infrared image taken by the Hubble Space Telescope. The Atacama Large Millimeter/submillimeter Array (ALMA) in Chile caught the fireworks-like activity when scientists took a new look at the star cluster called G286.21+0.17. This imagery shows the dynamic and chaotic process of star birth, as turbulence plays out on one side of the gas clouds, and stellar winds from the baby stars cause a stir on the other side.

Earth's Magnetic Field Could Be Changing Much Faster Than We Ever Realised
The Earth's magnetic field flips, every few hundred thousand years or so on average, which means magnetic north becomes magnetic south and vice versa (the planet doesn't actually turn upside down). New research suggests this change of direction can

How Your Heart Influences What You Perceive and Fear
The heartbeat and other bodily processes play a surprising role in shaping perception and cognition.
Researchers have recently shown that the distinct phases of the heartbeat exert sharply different effects on the brain’s processing of external and emotional stimuli.

This is one of the best pictures ever taken of ISS from Earth.
The pic was made by astrophotographer Thierry Legault on June 24 and 25, 2020 when International Space Station was passing in front of the Sun.
You can clearly see the station's robotic arm Canadarm2 and docked SpaceX Dragon capsule.
The Canadarm2 is 17.6 meters (57.7 feet) long when fully extended, but as you can see here, it was bent at the elbow over 90 degrees. At the time the picture was taken, an external pallet, or stowage platform, was attached to the end of the arm.
