Arp 220 is an ultra-luminous infrared #galaxy (ULIRG) that emits 300 times more light than the #MilkyWay. It also happens to glow brightest in infrared light, Webb's specialty.

This time-lapse of #Hubble images, spanning 22 years, traces the ongoing aftermath of #Supernova 1987A. Hubble shows a #shockwave from the #stellar explosion hitting a ring of material previously cast off by the dying #star.

Jupiter's monster storm, the Great Red Spot, was once so large that three Earths would fit inside it. But new measurements by NASA's Hubble Space Telescope reveal that the largest storm in our solar system has downsized significantly. The red spot, which has been raging for at least a hundred years, is only the width of one Earth.
The #Hubble images were taken in 1995, 2009, and 2014.

This is how Jupiter has protected earth for billions of years. The gravity of Jupiter keeps most asteroids and space rocks away from Earth. Without it earth would most likely be uninhabitable for humans. Mad respect for Jupiter.

Saturn's rings are 90% water

Saturn is home to the Solar System’s most epic ice rink. Being so far from the Sun, the water in its rings is frozen into ice. It is one of four planets that have rings around them - the other gas planets do too. However, the rest were undiscovered until the 1970s when probes went to explore them. Saturn’s were the first rings seen through telescopes from Earth.

As the air then descends, it becomes warmer and drier and therefore more stable. It blankets the region below and stabilizes the air contained within, causing people within that region to notice a calm before the storm.
