James Webb Space Telescope spies massive shockwave and baby dwarf galaxy

Shockwaves generated by a collision between the galaxies of Stephen’s Quintet and an intruding galaxy are driving strange processes in the intergalactic medium, the tenuous cloud of hotter-than-hot hydrogen plasma that exists in the space between galaxies.

new observations made with james webb space telescope (WEBB or JWST) and the Atacama Large Millimeter/submillimeter Array (alma) provides astronomers with good information about the intruder Galaxy NGC 7318b as it winds its way into this cluster of galaxies at a relative speed of about 1.8 million miles per hour (about 800 kilometers per second). fast enough to travel from earth until Moon And come back in only 15 minutes.
