JELLYFISH NEBULA - a supernova remnant sculpted by powerful shock waves moving through dense interstellar gas. IC 443 is the aftermath of a massive stellar explosion that occurred thousands of years ago, with the expanding shock fronts now colliding with surrounding molecular clouds. These violent interactions energize hydrogen, sulfur, and oxygen atoms, creating the complex filaments and stratified color layers that define the nebula’s structure. Its distinctive, jellyfish-like form emerges where the blast wave encounters regions of uneven density, compressing and heating the gas into luminous arcs and clumps. IC 443 is also a notable source of high-energy emission, with strong evidence of particle acceleration and a connection to a nearby neutron star.

Japanese probe Kaguya discovered a cave on the Moon 🌖😳 The diameter of the hole is about 65 meters, and the depth is about 50 meters. This pit leads to a tunnel under the surface. @thewonderofspace

A quantum mechanical system behind a barrier can have varying amounts of energy, but it can only absorb or emit specific amounts of this energy. The system is quantised. Tunnelling occurs more easily at a higher energy level than at a lower one so, statistically, a system with more energy is held captive for less time than one with less energy. This year’s #NobelPrize laureates in physics conducted experiments with an electrical circuit in which they demonstrated both quantum mechanical tunnelling and quantised energy levels in a system big enough to be held in the hand.

BREAKING NEWS The Royal Swedish Academy of Sciences has decided to award the 2025 #NobelPrize in Physics to John Clarke, Michel H. Devoret and John M. Martinis “for the discovery of macroscopic quantum mechanical tunnelling and energy quantisation in an electric circuit.”
