NASA Releases Images of Two Galaxies Merging in Fine Detail from the James Webb Space Telescope
The object, called ‘Arp 107’, is located about 465 million light-years from Earth and includes the elliptical galaxy PGC 32628 (left) and the spiral galaxy PGC 32620 (right), which collided with hundreds of millions of years ago. already and is currently joining.
James Webb Camera’s NIRCam instrument records images in the near-infrared range. Revealing details of stars and dusty gas connecting the two galaxies While data from MIRI instruments that probe in the mid-infrared region details of star-forming regions have been recorded. Similar to the discovery of dust belonging to the Polycyclic Aromatic Hydrocarbons group in the object Arp 107.
NASA’s Spitzer Space Telescope previously captured an infrared image of the object in 2005, but the images and data from the James Webb telescope were able to reveal even more detail by combining data from the NIRCam instrument and MIRI was released for the first time on September 18. .
The merger of the two galaxies allows dust and gas from the two galaxies to compress each other. Increase the opportunities and environment for stars to be born. But at the same time the merger can cause dust and gas to disperse in a turbulent way. and reduce the chance of forming new stars According to the latest discovery of James Webb camera data.
A merger or collision of two or more galaxies. It is a process that can happen in general. The Milky Way galaxy of which Earth is a part and the nearby Andromeda galaxy. They are heading towards each other at a speed of 110 kilometers per second. and they may converge in about 4,500 million years from now.
