James Webb Telescope found dusty skeleton in starburst galaxy

NASA Space Telescope James Webb (JWT) found a dusty skeleton in the starburst dwarf galaxy “NGC 4449.” It is the most recent cosmic image that the James Webb Telescope has captured.


NGC 4449 is a satellite galaxy surrounding the Milky Way located 12.5 million light-years away in the constellation of Canes Venatici.


Canes Venatici is a medium-sized constellation (group of stars) in the northern sky more easily visible from the northern hemisphere. Canes Venatici are also known as the Hunting Dogs.


The recently discovered galaxy NGC 4449 shares many similarities with our galaxy, the Large Magellanic Cloud (LMC). Both have a characteristics bar running through the middle of them. They are small and asymmetrical in design.


However, galaxy NGC 4449 shows a higher star formation rate along its entire length and width than LMC. LMC has only one extreme zone of star production, the 30 Doradus region (also known as Tarantula Nebula).


NGC 4449 is experiencing such a high level of star production. This phenomenon is called “starburst.” Starbursts occur when a collision or gravitational contact with another galaxy disturbs its molecular hydrogen gas.

Galaxy NGC 4449 is part of the M94 Group, comprised of two dozen galaxies. Hence, it interacts with several neighboured stars. The gravitational tidal forces have generated turbulence in the molecular gas throughout the star group.


It led to the gravitational collapse of massive spaces and the formation of many newborn star groups. The most recent image produced by JWT combines information from its Mid-infrared Instrument (MIRI) and Near-Infrared Camera (NIRCam).


It revealed the star group formation and other features in these images. Infrared vision capturing of the James Webb Telescope found a dusty skeleton in NGC 4449 as it is undergoing a star explosion or starburst due to consumption of smaller stars.
