New reports from James Webb indicate that a massive shockwave rippled through Stephan's Quintet and could mark the birth of a new galaxy.
first James Webb images
that marked the brand-new telescope’s first observations. Now, the quintet is at the center of Webb’s observations as it spied a shockwave barreling through the collective. The Atacama Large Millimeter/submillimeter Array has also been at the center of the new observations. The shockwave, which Webb astronomers attribute to the collision of an intruder galaxy known as NGC 731b with Stephan’s Quintet. The new galaxy has been forcing its way into the quintet at a relative speed of around 1.8 million MPH . At this speed, the galaxy could travel from Earth to the moon and back in a little over 15 minutes.
The collision between NGC 731b and Stephan’s Quintet has given birth to this new shockwave, though, which Webb observed moving at over one million miles per hour. The invasion of the quintet by this intruder galaxy has caused a rippling through the interstellar plasma of the galaxies, kicking up warm and cold molecular hydrogen gas amidst the quintet.This “recycling plant” of gases has been seen forming a giant cloud of gas that has since begun to break apart into a more fog-like appearance.
The importance of the data gathered from Webb observing this shockwave could have massive implications, too.
