James Webb Space Telescope is of Stephan’s Quintet
Astronomers using observations from Webb along with the Atacama Large Millimeter/submillimeter Array have discovered a sonic boom several times larger than the Milky Way, caused by colliding galaxies in Stephan’s Quintet. The findings, which were presented at an American Astronomical Society press conference on Jan. 9, revealed insights into gas clouds in Stephan’s Quintet along with the potential formation of a new galaxy.
“As this intruder crashes into the group, it is colliding with an old gas streamer that likely was caused by a previous interaction between two of the other galaxies, and is causing a giant shockwave to form,” Philip Appleton, an astronomer at Caltech’s Infrared Processing and Analysis Center and lead investigator on the project, said in a statement.
However, Appleton also adds that the team doesn’t quite fully understand the science and data behind the gas cycles yet. More research is needed in order to suss out its underlying mechanics and implications.
